## 0.7.4 (UNRELEASED)
|
|
|
|
FEATURES:
|
|
|
|
IMPROVEMENTS:
|
|
|
|
* build: Consul is now built with Go 1.7.5. [GH-2682]
|
|
|
|
BUG FIXES:
|
|
|
|
## 0.7.3 (January 26, 2017)
|
|
|
|
FEATURES:
|
|
|
|
* **KV Import/Export CLI:** `consul kv export` and `consul kv import` can be used to move parts of the KV tree between disconnected consul clusters, using JSON as the intermediate representation. [GH-2633]
|
|
* **Node Metadata:** Support for assigning user-defined metadata key/value pairs to nodes has been added. This can be viewed when looking up node info, and can be used to filter the results of various catalog and health endpoints. For more information, see the [Catalog](https://www.consul.io/docs/agent/http/catalog.html), [Health](https://www.consul.io/docs/agent/http/health.html), and [Prepared Query](https://www.consul.io/docs/agent/http/query.html) endpoint documentation, as well as the [Node Meta](https://www.consul.io/docs/agent/options.html#_node_meta) section of the agent configuration. [GH-2654]
|
|
* **Node Identifiers:** Consul agents can now be configured with a unique identifier, or they will generate one at startup that will persist across agent restarts. This identifier is designed to represent a node across all time, even if the name or address of the node changes. Identifiers are currently only exposed in node-related endpoints, but they will be used in future versions of Consul to help manage Consul servers and the Raft quorum in a more robust manner, as the quorum is currently tracked via addresses, which can change. [GH-2661]
|
|
* **Improved Blocking Queries:** Consul's [blocking query](https://www.consul.io/docs/agent/http.html#blocking-queries) implementation was improved to provide a much more fine-grained mechanism for detecting changes. For example, in previous versions of Consul blocking to wait on a change to a specific service would result in a wake up if any service changed. Now, wake ups are scoped to the specific service being watched, if possible. This support has been added to all endpoints that support blocking queries, nothing new is required to take advantage of this feature. [GH-2671]
|
|
* **GCE auto-discovery:** New `-retry-join-gce` configuration options added to allow bootstrapping by automatically discovering Google Cloud instances with a given tag at startup. [GH-2570]
|
|
|
|
IMPROVEMENTS:
|
|
|
|
* build: Consul is now built with Go 1.7.4. [GH-2676]
|
|
* cli: `consul kv get` now has a `-base64` flag to base 64 encode the value. [GH-2631]
|
|
* cli: `consul kv put` now has a `-base64` flag for setting values which are base 64 encoded. [GH-2632]
|
|
* ui: Added a notice that JS is required when viewing the web UI with JS disabled. [GH-2636]
|
|
|
|
BUG FIXES:
|
|
|
|
* agent: Redacted the AWS access key and secret key ID from the /v1/agent/self output so they are not disclosed. [GH-2677]
|
|
* agent: Fixed a rare startup panic due to a Raft/Serf race condition. [GH-1899]
|
|
* cli: Fixed a panic when an empty quoted argument was given to `consul kv put`. [GH-2635]
|
|
* tests: Fixed a race condition with check mock's map usage. [GH-2578]
|
|
|
|
## 0.7.2 (December 19, 2016)
|
|
|
|
FEATURES:
|
|
|
|
* **Keyring API:** A new `/v1/operator/keyring` HTTP endpoint was added that allows for performing operations such as list, install, use, and remove on the encryption keys in the gossip keyring. See the [Keyring Endpoint](https://www.consul.io/docs/agent/http/operator.html#keyring) for more details. [GH-2509]
|
|
* **Monitor API:** A new `/v1/agent/monitor` HTTP endpoint was added to allow for viewing streaming log output from the agent, similar to the `consul monitor` command. See the [Monitor Endpoint](https://www.consul.io/docs/agent/http/agent.html#agent_monitor) for more details. [GH-2511]
|
|
* **Reload API:** A new `/v1/agent/reload` HTTP endpoint was added for triggering a reload of the agent's configuration. See the [Reload Endpoint](https://www.consul.io/docs/agent/http/agent.html#agent_reload) for more details. [GH-2516]
|
|
* **Leave API:** A new `/v1/agent/leave` HTTP endpoint was added for causing an agent to gracefully shutdown and leave the cluster (previously, only `force-leave` was present in the HTTP API). See the [Leave Endpoint](https://www.consul.io/docs/agent/http/agent.html#agent_leave) for more details. [GH-2516]
|
|
* **Bind Address Templates (beta):** Consul agents now allow [go-sockaddr/template](https://godoc.org/github.com/hashicorp/go-sockaddr/template) syntax to be used for any bind address configuration (`advertise_addr`, `bind_addr`, `client_addr`, and others). This allows for easy creation of immutable images for Consul that can fetch their own address based on an interface name, network CIDR, address family from an actual RFC number, and many other possible schemes. This feature is in beta and we may tweak the template syntax before final release, but we encourage the community to try this and provide feedback. [GH-2563]
|
|
* **Complete ACL Coverage (beta):** Consul 0.8 will feature complete ACL coverage for all of Consul. To ease the transition to the new policies, a beta version of complete ACL support was added to help with testing and migration to the new features. Please see the [ACLs Internals Guide](https://www.consul.io/docs/internals/acl.html#version_8_acls) for more details. [GH-2594, GH-2592, GH-2590]
|
|
|
|
IMPROVEMENTS:
|
|
|
|
* agent: Defaults to `?pretty` JSON for HTTP API requests when in `-dev` mode. [GH-2518]
|
|
* agent: Updated Circonus metrics library and added new Circonus configration options for Consul for customizing check display name and tags. [GH-2555]
|
|
* agent: Added a checksum to UDP gossip messages to guard against packet corruption. [GH-2574]
|
|
* agent: Check whether a snapshot needs to be taken more often (every 5 seconds instead of 2 minutes) to keep the raft file smaller and to avoid doing huge truncations when writing lots of entries very quickly. [GH-2591]
|
|
* agent: Allow gossiping to suspected/recently dead nodes. [GH-2593]
|
|
* agent: Changed the gossip suspicion timeout to grow smoothly as the number of nodes grows. [GH-2593]
|
|
* agent: Added a deprecation notice for Atlas features to the CLI and docs. [GH-2597]
|
|
* agent: Give a better error message when the given data-dir is not a directory. [GH-2529]
|
|
|
|
BUG FIXES:
|
|
|
|
* agent: Fixed a panic when SIGPIPE signal was received. [GH-2404]
|
|
* api: Added missing Raft index fields to `CatalogService` structure. [GH-2366]
|
|
* api: Added missing notes field to `AgentServiceCheck` structure. [GH-2336]
|
|
* api: Changed type of `AgentServiceCheck.TLSSkipVerify` from `string` to `bool`. [GH-2530]
|
|
* api: Added new `HealthChecks.AggregatedStatus()` method that makes it easy get an overall health status from a list of checks. [GH-2544]
|
|
* api: Changed type of `KVTxnOp.Verb` from `string` to `KVOp`. [GH-2531]
|
|
* cli: Fixed an issue with the `consul kv put` command where a negative value would be interpreted as an argument to read from standard input. [GH-2526]
|
|
* ui: Fixed an issue where extra commas would be shown around service tags. [GH-2340]
|
|
* ui: Customized Bootstrap config to avoid missing font file references. [GH-2485]
|
|
* ui: Removed "Deregister" button as removing nodes from the catalog isn't a common operation and leads to lots of user confusion. [GH-2541]
|
|
|
|
## 0.7.1 (November 10, 2016)
|
|
|
|
BREAKING CHANGES:
|
|
|
|
* Child process reaping support has been removed, along with the `reap` configuration option. Reaping is also done via [dumb-init](https://github.com/Yelp/dumb-init) in the [Consul Docker image](https://github.com/hashicorp/docker-consul), so removing it from Consul itself simplifies the code and eases future maintainence for Consul. If you are running Consul as PID 1 in a container you will need to arrange for a wrapper process to reap child processes. [GH-1988]
|
|
* The default for `max_stale` has been increased to a near-indefinite threshold (10 years) to allow DNS queries to continue to be served in the event of a long outage with no leader. A new telemetry counter has also been added at `consul.dns.stale_queries` to track when agents serve DNS queries that are over a certain staleness (>5 seconds). [GH-2481]
|
|
* The api package's `PreparedQuery.Delete()` method now takes `WriteOptions` instead of `QueryOptions`. [GH-2417]
|
|
|
|
FEATURES:
|
|
|
|
* **Key/Value Store Command Line Interface:** New `consul kv` commands were added for easy access to all basic key/value store operations. [GH-2360]
|
|
* **Snapshot/Restore:** A new /v1/snapshot HTTP endpoint and corresponding set of `consul snapshot` commands were added for easy point-in-time snapshots for disaster recovery. Snapshots include all state managed by Consul's Raft [consensus protocol](/docs/internals/consensus.html), including Key/Value Entries, Service Catalog, Prepared Queries, Sessions, and ACLs. Snapshots can be restored on the fly into a completely fresh cluster. [GH-2396]
|
|
* **AWS auto-discovery:** New `-retry-join-ec2` configuration options added to allow bootstrapping by automatically discovering AWS instances with a given tag key/value at startup. [GH-2459]
|
|
|
|
IMPROVEMENTS:
|
|
|
|
* api: All session options can now be set when using `api.Lock()`. [GH-2372]
|
|
* agent: Added the ability to bind Serf WAN and LAN to different interfaces than the general bind address. [GH-2007]
|
|
* agent: Added a new `tls_skip_verify` configuration option for HTTP checks. [GH-1984]
|
|
* build: Consul is now built with Go 1.7.3. [GH-2281]
|
|
|
|
BUG FIXES:
|
|
|
|
* agent: Fixed a Go race issue with log buffering at startup. [GH-2262]
|
|
* agent: Fixed a panic during anti-entropy sync for services and checks. [GH-2125]
|
|
* agent: Fixed an issue on Windows where "wsarecv" errors were logged when CLI commands accessed the RPC interface. [GH-2356]
|
|
* agent: Syslog initialization will now retry on errors for up to 60 seconds to avoid a race condition at system startup. [GH-1610]
|
|
* agent: Fixed a panic when both -dev and -bootstrap-expect flags were provided. [GH-2464]
|
|
* agent: Added a retry with backoff when a session fails to invalidate after expiring. [GH-2435]
|
|
* agent: Fixed an issue where Consul would fail to start because of leftover malformed check/service state files. [GH-1221]
|
|
* agent: Fixed agent crashes on macOS Sierra by upgrading Go. [GH-2407, GH-2281]
|
|
* agent: Log a warning instead of success when attempting to deregister a nonexistent service. [GH-2492]
|
|
* api: Trim leading slashes from keys/prefixes when querying KV endpoints to avoid a bug with redirects in Go 1.7 (golang/go#4800). [GH-2403]
|
|
* dns: Fixed external services that pointed to consul addresses (CNAME records) not resolving to A-records. [GH-1228]
|
|
* dns: Fixed an issue with SRV lookups where the service address was different from the node's. [GH-832]
|
|
* dns: Fixed an issue where truncated records from a recursor query were improperly reported as errors. [GH-2384]
|
|
* server: Fixed the port numbers in the sample JSON inside peers.info. [GH-2391]
|
|
* server: Squashes ACL datacenter name to lower case and checks for proper formatting at startup. [GH-2059, GH-1778, GH-2478]
|
|
* ui: Fixed an XSS issue with the display of sessions and ACLs in the web UI. [GH-2456]
|
|
|
|
## 0.7.0 (September 14, 2016)
|
|
|
|
BREAKING CHANGES:
|
|
|
|
* The default behavior of `leave_on_terminate` and `skip_leave_on_interrupt` are now dependent on whether or not the agent is acting as a server or client. When Consul is started as a server the defaults for these are `false` and `true`, respectively, which means that you have to explicitly configure a server to leave the cluster. When Consul is started as a client the defaults are the opposite, which means by default, clients will leave the cluster if shutdown or interrupted. [GH-1909] [GH-2320]
|
|
* The `allow_stale` configuration for DNS queries to the Consul agent now defaults to `true`, allowing for better utilization of available Consul servers and higher throughput at the expense of weaker consistency. This is almost always an acceptable tradeoff for DNS queries, but this can be reconfigured to use the old default behavior if desired. [GH-2315]
|
|
* Output from HTTP checks is truncated to 4k when stored on the servers, similar to script check output. [GH-1952]
|
|
* Consul's Go API client will now send ACL tokens using HTTP headers instead of query parameters, requiring Consul 0.6.0 or later. [GH-2233]
|
|
* Removed support for protocol version 1, so Consul 0.7 is no longer compatible with Consul versions prior to 0.3. [GH-2259]
|
|
* The Raft peers information in `consul info` has changed format and includes information about the suffrage of a server, which will be used in future versions of Consul. [GH-2222]
|
|
* New [`translate_wan_addrs`](https://www.consul.io/docs/agent/options.html#translate_wan_addrs) behavior from [GH-2118] translates addresses in HTTP responses and could break clients that are expecting local addresses. A new `X-Consul-Translate-Addresses` header was added to allow clients to detect if translation is enabled for HTTP responses, and a "lan" tag was added to `TaggedAddresses` for clients that need the local address regardless of translation. [GH-2280]
|
|
* The behavior of the `peers.json` file is different in this version of Consul. This file won't normally be present and is used only during outage recovery. Be sure to read the updated [Outage Recovery Guide](https://www.consul.io/docs/guides/outage.html) for details. [GH-2222]
|
|
* Consul's default Raft timing is now set to work more reliably on lower-performance servers, which allows small clusters to use lower cost compute at the expense of reduced performance for failed leader detection and leader elections. You will need to configure Consul to get the same performance as before. See the new [Server Performance](https://www.consul.io/docs/guides/performance.html) guide for more details. [GH-2303]
|
|
|
|
FEATURES:
|
|
|
|
* **Transactional Key/Value API:** A new `/v1/txn` API was added that allows for atomic updates to and fetches from multiple entries in the key/value store inside of an atomic transaction. This includes conditional updates based on obtaining locks, and all other key/value store operations. See the [Key/Value Store Endpoint](https://www.consul.io/docs/agent/http/kv.html#txn) for more details. [GH-2028]
|
|
* **Native ACL Replication:** Added a built-in full replication capability for ACLs. Non-ACL datacenters can now replicate the complete ACL set locally to their state store and fall back to that if there's an outage. Additionally, this provides a good way to make a backup ACL datacenter, or to migrate the ACL datacenter to a different one. See the [ACL Internals Guide](https://www.consul.io/docs/internals/acl.html#replication) for more details. [GH-2237]
|
|
* **Server Connection Rebalancing:** Consul agents will now periodically reconnect to available Consul servers in order to redistribute their RPC query load. Consul clients will, by default, attempt to establish a new connection every 120s to 180s unless the size of the cluster is sufficiently large. The rate at which agents begin to query new servers is proportional to the size of the Consul cluster (servers should never receive more than 64 new connections per second per Consul server as a result of rebalancing). Clusters in stable environments who use `allow_stale` should see a more even distribution of query load across all of their Consul servers. [GH-1743]
|
|
* **Raft Updates and Consul Operator Interface:** This version of Consul upgrades to "stage one" of the v2 HashiCorp Raft library. This version offers improved handling of cluster membership changes and recovery after a loss of quorum. This version also provides a foundation for new features that will appear in future Consul versions once the remainder of the v2 library is complete. [GH-2222] <br> Consul's default Raft timing is now set to work more reliably on lower-performance servers, which allows small clusters to use lower cost compute at the expense of reduced performance for failed leader detection and leader elections. You will need to configure Consul to get the same performance as before. See the new [Server Performance](https://www.consul.io/docs/guides/performance.html) guide for more details. [GH-2303] <br> Servers will now abort bootstrapping if they detect an existing cluster with configured Raft peers. This will help prevent safe but spurious leader elections when introducing new nodes with `bootstrap_expect` enabled into an existing cluster. [GH-2319] <br> Added new `consul operator` command, HTTP endpoint, and associated ACL to allow Consul operators to view and update the Raft configuration. This allows a stale server to be removed from the Raft peers without requiring downtime and peers.json recovery file use. See the new [Consul Operator Command](https://www.consul.io/docs/commands/operator.html) and the [Consul Operator Endpoint](https://www.consul.io/docs/agent/http/operator.html) for details, as well as the updated [Outage Recovery Guide](https://www.consul.io/docs/guides/outage.html). [GH-2312]
|
|
* **Serf Lifeguard Updates:** Implemented a new set of feedback controls for the gossip layer that help prevent degraded nodes that can't meet the soft real-time requirements from erroneously causing `serfHealth` flapping in other, healthy nodes. This feature tunes itself automatically and requires no configuration. [GH-2101]
|
|
* **Prepared Query Near Parameter:** Prepared queries support baking in a new `Near` sorting parameter. This allows results to be sorted by network round trip time based on a static node, or based on the round trip time from the Consul agent where the request originated. This can be used to find a co-located service instance is one is available, with a transparent fallback to the next best alternate instance otherwise. [GH-2137]
|
|
* **Automatic Service Deregistration:** Added a new `deregister_critical_service_after` timeout field for health checks which will cause the service associated with that check to get deregistered if the check is critical for longer than the timeout. This is useful for cleanup of health checks registered natively by applications, or in other situations where services may not always be cleanly shutdown. [GH-679]
|
|
* **WAN Address Translation Everywhere:** Extended the [`translate_wan_addrs`](https://www.consul.io/docs/agent/options.html#translate_wan_addrs) config option to also translate node addresses in HTTP responses, making it easy to use this feature from non-DNS clients. [GH-2118]
|
|
* **RPC Retries:** Consul will now retry RPC calls that result in "no leader" errors for up to 5 seconds. This allows agents to ride out leader elections with a delayed response vs. an error. [GH-2175]
|
|
* **Circonus Telemetry Support:** Added support for Circonus as a telemetry destination. [GH-2193]
|
|
|
|
IMPROVEMENTS:
|
|
|
|
* agent: Reap time for failed nodes is now configurable via new `reconnect_timeout` and `reconnect_timeout_wan` config options ([use with caution](https://www.consul.io/docs/agent/options.html#reconnect_timeout)). [GH-1935]
|
|
* agent: Joins based on a DNS lookup will use TCP and attempt to join with the full list of returned addresses. [GH-2101]
|
|
* agent: Consul will now refuse to start with a helpful message if the same UNIX socket is used for more than one listening endpoint. [GH-1910]
|
|
* agent: Removed an obsolete warning message when Consul starts on Windows. [GH-1920]
|
|
* agent: Defaults bind address to 127.0.0.1 when running in `-dev` mode. [GH-1878]
|
|
* agent: Added version information to the log when Consul starts up. [GH-1404]
|
|
* agent: Added timing metrics for HTTP requests in the form of `consul.http.<verb>.<path>`. [GH-2256]
|
|
* build: Updated all vendored dependencies. [GH-2258]
|
|
* build: Consul releases are now built with Go 1.6.3. [GH-2260]
|
|
* checks: Script checks now support an optional `timeout` parameter. [GH-1762]
|
|
* checks: HTTP health checks limit saved output to 4K to avoid performance issues. [GH-1952]
|
|
* cli: Added a `-stale` mode for watchers to allow them to pull data from any Consul server, not just the leader. [GH-2045] [GH-917]
|
|
* dns: Consul agents can now limit the number of UDP answers returned via the DNS interface. The default number of UDP answers is `3`, however by adjusting the `dns_config.udp_answer_limit` configuration parameter, it is now possible to limit the results down to `1`. This tunable provides environments where RFC3484 section 6, rule 9 is enforced with an important workaround in order to preserve the desired behavior of randomized DNS results. Most modern environments will not need to adjust this setting as this RFC was made obsolete by RFC 6724\. See the [agent options](https://www.consul.io/docs/agent/options.html#udp_answer_limit) documentation for additional details for when this should be used. [GH-1712]
|
|
* dns: Consul now compresses all DNS responses by default. This prevents issues when recursing records that were originally compressed, where Consul would sometimes generate an invalid, uncompressed response that was too large. [GH-2266]
|
|
* dns: Added a new `recursor_timeout` configuration option to set the timeout for Consul's internal DNS client that's used for recursing queries to upstream DNS servers. [GH-2321]
|
|
* dns: Added a new `-dns-port` command line option so this can be set without a config file. [GH-2263]
|
|
* ui: Added a new network tomography visualization to the UI. [GH-2046]
|
|
|
|
BUG FIXES:
|
|
|
|
* agent: Fixed an issue where a health check's output never updates if the check status doesn't change after the Consul agent starts. [GH-1934]
|
|
* agent: External services can now be registered with ACL tokens. [GH-1738]
|
|
* agent: Fixed an issue where large events affecting many nodes could cause infinite intent rebroadcasts, leading to many log messages about intent queue overflows. [GH-1062]
|
|
* agent: Gossip encryption keys are now validated before being made persistent in the keyring, avoiding delayed feedback at runtime. [GH-1299]
|
|
* dns: Fixed an issue where DNS requests for SRV records could be incorrectly trimmed, resulting in an ADDITIONAL section that was out of sync with the ANSWER. [GH-1931]
|
|
* dns: Fixed two issues where DNS requests for SRV records on a prepared query that failed over would report the wrong domain and fail to translate addresses. [GH-2218] [GH-2220]
|
|
* server: Fixed a deadlock related to sorting the list of available datacenters by round trip time. [GH-2130]
|
|
* server: Fixed an issue with the state store's immutable radix tree that would prevent it from using cached modified objects during transactions, leading to extra copies and increased memory / GC pressure. [GH-2106]
|
|
* server: Upgraded Bolt DB to v1.2.1 to fix an issue on Windows where Consul would sometimes fail to start due to open user-mapped sections. [GH-2203]
|
|
|
|
OTHER CHANGES:
|
|
|
|
* build: Switched from Godep to govendor. [GH-2252]
|
|
|
|
## 0.6.4 (March 16, 2016)
|
|
|
|
BACKWARDS INCOMPATIBILITIES:
|
|
|
|
* Added a new `query` ACL type to manage prepared query names, and stopped capturing
|
|
ACL tokens by default when prepared queries are created. This won't affect existing
|
|
queries and how they are executed, but this will affect how they are managed. Now
|
|
management of prepared queries can be delegated within an organization. If you use
|
|
prepared queries, you'll need to read the
|
|
[Consul 0.6.4 upgrade instructions](https://www.consul.io/docs/upgrade-specific.html)
|
|
before upgrading to this version of Consul. [GH-1748]
|
|
* Consul's Go API client now pools connections by default, and requires you to manually
|
|
opt-out of this behavior. Previously, idle connections were supported and their
|
|
lifetime was managed by a finalizer, but this wasn't reliable in certain situations.
|
|
If you reuse an API client object during the lifetime of your application, then there's
|
|
nothing to do. If you have short-lived API client objects, you may need to configure them
|
|
using the new `api.DefaultNonPooledConfig()` method to avoid leaking idle connections. [GH-1825]
|
|
* Consul's Go API client's `agent.UpdateTTL()` function was updated in a way that will
|
|
only work with Consul 0.6.4 and later. The `agent.PassTTL()`, `agent.WarnTTL()`, and
|
|
`agent.FailTTL()` functions were not affected and will continue work with older
|
|
versions of Consul. [GH-1794]
|
|
|
|
FEATURES:
|
|
|
|
* Added new template prepared queries which allow you to define a prefix (possibly even
|
|
an empty prefix) to apply prepared query features like datacenter failover to multiple
|
|
services with a single query definition. This makes it easy to apply a common policy to
|
|
multiple services without having to manage many prepared queries. See
|
|
[Prepared Query Templates](https://www.consul.io/docs/agent/http/query.html#templates)
|
|
for more details. [GH-1764]
|
|
* Added a new ability to translate address lookups when doing queries of nodes in
|
|
remote datacenters via DNS using a new `translate_wan_addrs` configuration
|
|
option. This allows the node to be reached within its own datacenter using its
|
|
local address, and reached from other datacenters using its WAN address, which is
|
|
useful in hybrid setups with mixed networks. [GH-1698]
|
|
|
|
IMPROVEMENTS:
|
|
|
|
* Added a new `disable_hostname` configuration option to control whether Consul's
|
|
runtime telemetry gets prepended with the host name. All of the telemetry
|
|
configuration has also been moved to a `telemetry` nested structure, but the old
|
|
format is currently still supported. [GH-1284]
|
|
* Consul's Go dependencies are now vendored using Godep. [GH-1714]
|
|
* Added support for `EnableTagOverride` for the catalog in the Go API client. [GH-1726]
|
|
* Consul now ships built from Go 1.6. [GH-1735]
|
|
* Added a new `/v1/agent/check/update/<check id>` API for updating TTL checks which
|
|
makes it easier to send large check output as part of a PUT body and not a query
|
|
parameter. [GH-1785].
|
|
* Added a default set of `Accept` headers for HTTP checks. [GH-1819]
|
|
* Added support for RHEL7/Systemd in Terraform example. [GH-1629]
|
|
|
|
BUG FIXES:
|
|
|
|
* Updated the internal web UI (`-ui` option) to latest released build, fixing
|
|
an ACL-related issue and the broken settings icon. [GH-1619]
|
|
* Fixed an issue where blocking KV reads could miss updates and return stale data
|
|
when another key whose name is a prefix of the watched key was updated. [GH-1632]
|
|
* Fixed the redirect from `/` to `/ui` when the internal web UI (`-ui` option) is
|
|
enabled. [GH-1713]
|
|
* Updated memberlist to pull in a fix for leaking goroutines when performing TCP
|
|
fallback pings. This affected users with frequent UDP connectivity problems. [GH-1802]
|
|
* Added a fix to trim UDP DNS responses so they don't exceed 512 bytes. [GH-1813]
|
|
* Updated go-dockerclient to fix Docker health checks with Docker 1.10. [GH-1706]
|
|
* Removed fixed height display of nodes and services in UI, leading to broken displays
|
|
when a node has a lot of services. [GH-2055]
|
|
|
|
## 0.6.3 (January 15, 2016)
|
|
|
|
BUG FIXES:
|
|
|
|
* Fixed an issue when running Consul as PID 1 in a Docker container where
|
|
it could consume CPU and show spurious failures for health checks, watch
|
|
handlers, and `consul exec` commands [GH-1592]
|
|
|
|
## 0.6.2 (January 13, 2016)
|
|
|
|
SECURITY:
|
|
|
|
* Build against Go 1.5.3 to mitigate a security vulnerability introduced
|
|
in Go 1.5. For more information, please see https://groups.google.com/forum/#!topic/golang-dev/MEATuOi_ei4
|
|
|
|
This is a security-only release; other than the version number and building
|
|
against Go 1.5.3, there are no changes from 0.6.1.
|
|
|
|
## 0.6.1 (January 6, 2016)
|
|
|
|
BACKWARDS INCOMPATIBILITIES:
|
|
|
|
* The new `-monitor-retry` option to `consul lock` defaults to 3. This
|
|
will cause the lock monitor to retry up to 3 times, waiting 1s between
|
|
each attempt if it gets a 500 error from the Consul servers. For the
|
|
vast majority of use cases this is desirable to prevent the lock from
|
|
being given up during a brief period of Consul unavailability. If you
|
|
want to get the previous default behavior you will need to set the
|
|
`-monitor-retry=0` option.
|
|
|
|
IMPROVEMENTS:
|
|
|
|
* Consul is now built with Go 1.5.2
|
|
* Added source IP address and port information to RPC-related log error
|
|
messages and HTTP access logs [GH-1513] [GH-1448]
|
|
* API clients configured for insecure SSL now use an HTTP transport that's
|
|
set up the same way as the Go default transport [GH-1526]
|
|
* Added new per-host telemetry on DNS requests [GH-1537]
|
|
* Added support for reaping child processes which is useful when running
|
|
Consul as PID 1 in Docker containers [GH-1539]
|
|
* Added new `-ui` command line and `ui` config option that enables a built-in
|
|
Consul web UI, making deployment much simpler [GH-1543]
|
|
* Added new `-dev` command line option that creates a completely in-memory
|
|
standalone Consul server for development
|
|
* Added a Solaris build, now that dependencies have been updated to support
|
|
it [GH-1568]
|
|
* Added new `-try` option to `consul lock` to allow it to timeout with an error
|
|
if it doesn't acquire the lock [GH-1567]
|
|
* Added a new `-monitor-retry` option to `consul lock` to help ride out brief
|
|
periods of Consul unavailabily without causing the lock to be given up [GH-1567]
|
|
|
|
BUG FIXES:
|
|
|
|
* Fixed broken settings icon in web UI [GH-1469]
|
|
* Fixed a web UI bug where the supplied token wasn't being passed into
|
|
the internal endpoint, breaking some pages when multiple datacenters
|
|
were present [GH-1071]
|
|
|
|
## 0.6.0 (December 3, 2015)
|
|
|
|
BACKWARDS INCOMPATIBILITIES:
|
|
|
|
* A KV lock acquisition operation will now allow the lock holder to
|
|
update the key's contents without giving up the lock by doing another
|
|
PUT with `?acquire=<session>` and providing the same session that
|
|
is holding the lock. Previously, this operation would fail.
|
|
|
|
FEATURES:
|
|
|
|
* Service ACLs now apply to service discovery [GH-1024]
|
|
* Added event ACLs to guard firing user events [GH-1046]
|
|
* Added keyring ACLs for gossip encryption keyring operations [GH-1090]
|
|
* Added a new TCP check type that does a connect as a check [GH-1130]
|
|
* Added new "tag override" feature that lets catalog updates to a
|
|
service's tags flow down to agents [GH-1187]
|
|
* Ported in-memory database from LMDB to an immutable radix tree to improve
|
|
read throughput, reduce garbage collection pressure, and make Consul 100%
|
|
pure Go [GH-1291]
|
|
* Added support for sending telemetry to DogStatsD [GH-1293]
|
|
* Added new network tomography subsystem that estimates the network
|
|
round trip times between nodes and exposes that in raw APIs, as well
|
|
as in existing APIs (find the service node nearest node X); also
|
|
includes a new `consul rtt` command to query interactively [GH-1331]
|
|
* Consul now builds under Go 1.5.1 by default [GH-1345]
|
|
* Added built-in support for running health checks inside Docker containers
|
|
[GH-1343]
|
|
* Added prepared queries which support service health queries with rich
|
|
features such as filters for multiple tags and failover to remote datacenters
|
|
based on network coordinates; these are available via HTTP as well as the
|
|
DNS interface [GH-1389]
|
|
|
|
BUG FIXES:
|
|
|
|
* Fixed expired certificates in unit tests [GH-979]
|
|
* Allow services with `/` characters in the UI [GH-988]

|
|
* Added missing support for AAAA queries for nodes [GH-1222]
|
|
* Tokens passed from the CLI or API work for maint mode [GH-1230]
|
|
* Fixed service deregister/reregister flaps that could happen during
|
|
`consul reload` [GH-1235]
|
|
* Fixed the Go API client to properly distinguish between expired sessions
|
|
and sessions that don't exist [GH-1041]
|
|
* Fixed the KV section of the UI to work on Safari [GH-1321]
|
|
* Cleaned up JavaScript for built-in UI with bug fixes [GH-1338]
|
|
|
|
IMPROVEMENTS:
|
|
|
|

|
|
* Advertised gossip/rpc addresses can now be configured [GH-1004]
|
|

|
|
[GH-1006]
|
|
* Agents now remember check state across restarts [GH-1009]
|
|
* Always run ACL tests by default in API tests [GH-1030]
|
|
* Consul now refuses to start if there are multiple private IPs [GH-1099]
|
|
* Improved efficiency of servers managing incoming connections from agents
|
|
[GH-1170]
|
|
* Added logging of the DNS client addresses in error messages [GH-1166]
|
|
* Added `-http-port` option to change the HTTP API port number [GH-1167]
|
|
* Atlas integration options are reload-able via SIGHUP [GH-1199]
|
|
* Atlas endpoint is a configurable option and CLI arg [GH-1201]
|
|
* Added `-pass-stdin` option to `consul lock` command [GH-1200]
|
|
* Enables the `/v1/internal/ui/*` endpoints, even if `-ui-dir` isn't set
|
|
[GH-1215]
|
|
* Added HTTP method to Consul's log output for better debugging [GH-1270]
|
|
* Lock holders can `?acquire=<session>` a key again with the same session
|
|
that holds the lock to update a key's contents without releasing the
|
|
lock [GH-1291]
|
|
* Improved an O(n^2) algorithm in the agent's catalog sync code [GH-1296]
|
|

|
|
Consul to avoid conflicts with other packages [GH-1310] [GH-1327]
|
|
* Added new `X-Consul-Token` HTTP header option to avoid passing tokens
|
|
in the query string [GH-1318]
|
|
* Increased session TTL max to 24 hours (use with caution, see note added
|
|
to the Session HTTP endpoint documentation) [GH-1412]
|
|
* Added support to the API client for retrying lock monitoring when Consul
|
|
is unavailable, helping prevent false indications of lost locks (eg. apps
|
|
like Vault can avoid failing over when a Consul leader election occurs)
|
|
[GH-1457]
|
|
* Added reap of receive buffer space for idle streams in the connection
|
|
pool [GH-1452]
|
|
|
|
MISC:
|
|
|
|
* Lots of docs fixes
|
|
* Lots of Vagrantfile cleanup
|
|
* Data migrator utility removed to eliminate cgo dependency [GH-1309]
|
|
|
|
UPGRADE NOTES:
|
|
|
|
* Consul will refuse to start if the data directory contains an "mdb" folder.
|
|
This folder was used in versions of Consul up to 0.5.1. Consul version 0.5.2
|
|
included a baked-in utility to automatically upgrade the data format, but
|
|
this has been removed in Consul 0.6 to eliminate the dependency on cgo.
|
|
* New service read, event firing, and keyring ACLs may require special steps to
|
|
perform during an upgrade if ACLs are enabled and set to deny by default.
|
|
* Consul will refuse to start if there are multiple private IPs available, so
|
|
if this is the case you will need to configure Consul's advertise or bind
|
|
addresses before upgrading.
|
|
|
|
See https://www.consul.io/docs/upgrade-specific.html for detailed upgrade
|
|
instructions.

|
|
* Datacenter name is case insensitive for DNS lookups
|
|
* Queries for invalid datacenters do not leak sockets [GH-807]
|
|
|
|
IMPROVEMENTS:

|
|
## 0.5.0 (February 19, 2015)
|
|
|
|
FEATURES:
|
|
|
|
* Key rotation support for gossip layer. This allows the `encrypt` key
|
|
to be changed globally. See "keyring" command. [GH-336]
|
|
* Options to join the WAN pool on start (`start_join_wan`, `retry_join_wan`) [GH-477]
|
|
* Optional HTTPS interface [GH-478]
|
|
* Ephemeral keys via "delete" session behavior. This allows keys to be deleted when
|
|
a session is invalidated instead of having the lock released. Adds new "Behavior"
|
|
field to Session which is configurable. [GH-487]
|
|
* Reverse DNS lookups via PTR for IPv4 and IPv6 [GH-475]
|
|
* API added checks and services are persisted. This means services and
|
|
checks will survive a crash or restart. [GH-497]
|
|
* ACLs can now protect service registration. Users in blacklist mode should
|
|
allow registrations before upgrading to prevent a service disruption. [GH-506] [GH-465]
|
|
* Sessions support a heartbeat failure detector via use of TTLs. This adds a new
|
|
"TTL" field to Sessions and a `/v1/session/renew` endpoint. Heartbeats act like a
|
|
failure detector (health check), but are managed by the servers. [GH-524] [GH-172]
|
|
* Support for service specific IP addresses. This allows the service to advertise an
|
|
address that is different from the agent. [GH-229] [GH-570]
|
|
* Support KV Delete with Check-And-Set [GH-589]
|
|
* Merge `armon/consul-api` into `api` as official Go client.

|
|
* Support for native HTTP health checks [GH-592]
|
|
* Support for node and service maintenance modes [GH-606]
|
|
* Added new "consul maint" command to easily toggle maintenance modes [GH-625]
|
|
* Added new "consul lock" command for simple highly-available deployments.
|
|
This lets Consul manage the leader election and easily handle N+1 deployments
|
|
without the applications being Consul aware. [GH-619]
|
|
* Multiple checks can be associated with a service [GH-591] [GH-230]
|
|
|
|
BUG FIXES:
|
|
|
|
* Fixed X-Consul-Index calculation for KV ListKeys
|
|
* Fixed errors under extremely high read parallelism
|
|
* Fixed issue causing event watches to not fire reliably [GH-479]
|
|
* Fixed non-monotonic X-Consul-Index with key deletion [GH-577] [GH-195]
|
|
* Fixed use of default instead of custom TLD in some DNS responses [GH-582]
|
|
* Fixed memory leaks in API client when an error response is returned [GH-608]
|
|
* Fixed issues with graceful leave in single-node bootstrap cluster [GH-621]
|
|
* Fixed issue preventing node reaping [GH-371]
|
|
* Fixed gossip stability at very large scale
|
|
* Fixed string of rpc error: rpc error: ... no known leader. [GH-611]

|
* Improved K/V blocking query performance [GH-578]
|
|
* CLI respects CONSUL_RPC_ADDR environment variable to load parameter [GH-542]
|
|

|
|
* Added support for defining multiple services per configuration file [GH-433]
|
|
* Added support for defining multiple checks per configuration file [GH-433]
|
|
* Allow mixing of service and check definitions in a configuration file [GH-433]
|
|
* Allow notes for checks in service definition file [GH-449]
|
|
* Random stagger for agent checks to prevent thundering herd [GH-546]
|
|
* More useful metrics are sent to statsd/statsite
|
|
* Added configuration to set custom HTTP headers (CORS) [GH-558]
|
|
* Reject invalid configurations to simplify validation [GH-576]
|
|
* Guard against accidental cluster mixing [GH-580] [GH-260]
|
|
* Added option to filter DNS results on warning [GH-595]
|
|
* Improve write throughput with raft log caching [GH-604]
|
|
* Added ability to bind RPC and HTTP listeners to UNIX sockets [GH-587] [GH-612]
|
|
* K/V HTTP endpoint returns 400 on conflicting flags [GH-634] [GH-432]
|
|
|
|
MISC:
|
|
|
|
* UI confirms before deleting key sub-tree [GH-520]
|
|
* More useful output in "consul version" [GH-480]
|
|
* Many documentation improvements
|
|
* Reduce log messages when quorum member is logs [GH-566]
|
|
|
|
UPGRADE NOTES:
|
|
|
|
* If `acl_default_policy` is "deny", ensure tokens are updated to enable
|
|
service registration to avoid a service disruption. The new ACL policy
|
|
can be submitted with 0.4 before upgrading to 0.5 where it will be
|
|
enforced.
|
|
|
|
* Servers running 0.5.X cannot be mixed with older servers. (Any client
|
|
version is fine). There is a 15 minute upgrade window where mixed
|
|
versions are allowed before older servers will panic due to an unsupported
|
|
internal command. This is due to the new KV tombstones which are internal
|
|
to servers.
|
|
|
|
## 0.4.1 (October 20, 2014)
|
|
|
|

|
|
|
|
## 0.4.0 (September 5, 2014)
|
|
|
|
FEATURES:
|
|
|
|
* Fine-grained ACL system to restrict access to KV store. Clients
|
|
use tokens which can be restricted to (read, write, deny) permissions
|
|
using longest-prefix matches.
|
|
|
|
* Watch mechanisms added to invoke a handler when data changes in consul.
|
|
Used with the `consul watch` command, or by specifying `watches` in
|
|
an agent configuration.
|
|
|
|
* Event system added to support custom user events. Events are fired using
|
|
the `consul event` command. They are handled using a standard watch.
|
|
|
|
* Remote execution using `consul exec`. This allows for command execution on remote
|
|
instances mediated through Consul.
|
|
|
|
* RFC-2782 style DNS lookups supported
|
|
|
|
* UI improvements, including support for ACLs.
|
|
|
|
IMPROVEMENTS:

* New `statsd_add` config for Statsd support. [GH-247]
|
|
* New `addresses` config for providing an override to `client_addr` for
|
|
DNS, HTTP, or RPC endpoints. [GH-301] [GH-253]
|
|
* Support [Checkpoint](http://checkpoint.hashicorp.com) for security bulletins
|
|
and update announcements.
|
|
|
|
BUG FIXES:
|
|
|
|
* Fixed race condition in `-bootstrap-expect` [GH-254]
|
|
* Require PUT to /v1/session/destroy [GH-285]
|
|
* Fixed registration race condition [GH-300] [GH-279]
