if the provided value is empty string then the client services
(DNS, HTTP, HTTPS, GRPC) are not listening and the user is not notified
in any way about what's happening.
Also, since a not provided client_addr defaults to 127.0.0.1, we make sure
we are not getting unwanted warnings

This struct allows us to move all the deprecated config options off of
the main config struct, and keeps all the deprecation logic in a single
place, instead of spread across 3+ places.

* agent: add failures_before_warning setting
The new setting allows users to specify the number of check failures
that have to happen before a service status us updated to be `warning`.
This allows for more visibility for detected issues without creating
alerts and pinging administrators. Unlike the previous behavior, which
caused the service status to not update until it reached the configured
`failures_before_critical` setting, now Consul updates the Web UI view
with the `warning` state and the output of the service check when
`failures_before_warning` is breached.
The default value of `FailuresBeforeWarning` is the same as the value of
`FailuresBeforeCritical`, which allows for retaining the previous default
behavior of not triggering a warning.
When `FailuresBeforeWarning` is set to a value higher than that of
`FailuresBeforeCritical it has no effect as `FailuresBeforeCritical`
takes precedence.

This field was never user-configurable. We always overwrote the value with 120s from
NonUserSource. However, we also never copied the value from RuntimeConfig to consul.Config,
So the value in NonUserSource was always ignored, and we used the default value of 30s
set by consul.DefaultConfig.
All of this code is an unnecessary distraction because a user can not actually configure
this value.
This commit removes the fields and uses a constant value instad. Someone attempting to set
acl.disabled_ttl in their config will now get an error about an unknown field, but previously
the value was completely ignored, so the new behaviour seems more correct.
We have to keep this field in the AutoConfig response for backwards compatibility, but the value
will be ignored by the client, so it doesn't really matter what value we set.
This field has been unnecessary for a while now. It was always set to the same value
as PrimaryDatacenter. So we can remove the duplicate field and use PrimaryDatacenter
directly.
This change was made by GoLand refactor, which did most of the work for me.
The blocking query backend sets the default value on the server side.
The streaming backend does not using blocking queries, so we must set the timeout on
the client.
This change adds a new `dns_config.recursor_strategy` option which
controls how Consul queries DNS resolvers listed in the `recursors`
config option. The supported options are `sequential` (default), and
`random`.
Closes#8807

And remove BuildAndValidate. This commit completes some earlier work to reduce the config
interface a single Load function.
The last remaining test was converted to use Load instad of BuildAndValidate.
The hcl decoding apparently uses strconv.ParseInt, which fails to parse a 64bit int.
Since hcl v1 is basically EOl, it seems unlikely we'll fix this in hcl.
Since this test is only about loading values from config files, the extra large number
doesn't seem important. Trim a few zeros from the numbers so that they parse
properly on 32bit platforms.
Also skip a slow test when -short is used.
CatalogDestinationsOnly is a passthrough that would enable dialing
addresses outside of Consul's catalog. However, when this flag is set to
true only _connect_ endpoints for services can be dialed.
This flag is being renamed to signal that non-Connect endpoints can't be
dialed by transparent proxies when the value is set to true.
The bulk of this commit is moving the LeaderRoutineManager from the agent/consul package into its own package: lib/gort. It also got a renaming and its Start method now requires a context. Requiring that context required updating a whole bunch of other places in the code.
No config entry needs a Kind field. It is only used to determine the Go type to
target. As we introduce new config entries (like this one) we can remove the kind field
and have the GetKind method return the single supported value.
In this case (similar to proxy-defaults) the Name field is also unnecessary. We always
use the same value. So we can omit the name field entirely.
This config entry is being renamed primarily because in k8s the name
cluster could be confusing given that the config entry applies across
federated datacenters.
Additionally, this config entry will only apply to Consul as a service
mesh, so the more generic "cluster" name is not needed.
This PR replaces the original boolean used to configure transparent
proxy mode. It was replaced with a string mode that can be set to:
- "": Empty string is the default for when the setting should be
defaulted from other configuration like config entries.
- "direct": Direct mode is how applications originally opted into the
mesh. Proxy listeners need to be dialed directly.
- "transparent": Transparent mode enables configuring Envoy as a
transparent proxy. Traffic must be captured and redirected to the
inbound and outbound listeners.
This PR also adds a struct for transparent proxy specific configuration.
Initially this is not stored as a pointer. Will revisit that decision
before GA.

Some TLS servers require SNI, but the Golang HTTP client doesn't
include it in the ClientHello when connecting to an IP address. This
change adds a new TLSServerName field to health check definitions to
optionally set it. This fixes#9473.
Replace the large table of tests with individual calls to run(). By using
runCase, failure messages will include the line number for the test case, as
well as a line number from the test functions.
Example:
=== FAIL: agent/config TestLoad_IntegrationWithFlags/failing_case (0.01s)
runtime_test.go:4721: case: failing case
runtime_test.go:4864: error "data_dir cannot be empty" does not contain "I expected this error"
Previous:
runtime_test.go:4864: error "data_dir cannot be empty" does not contain "I expected this error"
Without the line number to the testCase data, debugging these tests is
difficult. It is impossible to jump directly to the test case, and
difficult to find the location because of many similarly named cases.
AEInterval is overridden by NonUserSource, so there is no way for a user
to set this value. These two cases represented impossible real world
scenarios.
Instead the test is replaced with one that shows that the AEInterval can
not be set by config.
This change allows us to remove the hcltail and jsontail fields from
testCase
This commit makes a number of changes that should make
TestLoad_FullConfig easier to work with, and make the test more like
real world scenarios.
* use separate files in testdata/ dir to store the config source.
Separate files are much easier to edit because editors can syntax
highlight json/hcl, and it makes strings easier to find. Previously
trying to find strings would match strings used in other tests.
* use the exported config.Load interface instead of internal NewBuilder
and BuildAndValidate.
* remove the tail config overrides, which are only necessary with
nonZero works.
This commit reduces the interface to Load() a bit, in preparation for
unexporting NewBuilder and having everything call Load.
The three arguments are reduced to a single argument by moving the other
two into the options struct.
The three return values are reduced to two by moving the RuntimeConfig
and Warnings into a LoadResult struct.
This change allows us to re-use these functions in other places without the Builder, and makes it
more explicit about which functions can warn/error and which can not.
A golden file makes the expected value easier to work with. This change also
removes a number of shims for enterprise and replaces them with a single one
for the golden filename.
* Display a warning when rpc.enable_streaming = true is set on a client
This option has no effect when running as an agent
* Added warning when server starts with use_streaming_backend but without rpc.enable_streaming
* Added unit test
It is no safe to assumes that the mapstructure keys will contain all the keys because some config can be specified
with command line flags or literals.
This change allows us to remove the json marshal/unmarshal cycle for command line flags, which will allow
us to remove all of the hcl/json struct tags on config fields.
Add a skip condition to all tests slower than 100ms.
This change was made using `gotestsum tool slowest` with data from the
last 3 CI runs of master.
See https://github.com/gotestyourself/gotestsum#finding-and-skipping-slow-tests
With this change:
```
$ time go test -count=1 -short ./agent
ok github.com/hashicorp/consul/agent 0.743s
real 0m4.791s
$ time go test -count=1 -short ./agent/consul
ok github.com/hashicorp/consul/agent/consul 4.229s
real 0m8.769s
```
And remove the devMode field from builder.
This change helps make the Builder state more explicit by moving inputs to the BuilderOps struct,
leaving only fields that can change during Builder.Build on the Builder struct.
Using the LiteralSource makes it much easier to find default values, because an IDE reports
the location of a default. With an HCL string they are harder to discover.
Also removes unnecessary mapstructure.Decodes of constant values.
Header is: X-Consul-Default-ACL-Policy=<allow|deny>
This is of particular utility when fetching matching intentions, as the
fallthrough for a request that doesn't match any intentions is to
enforce using the default acl policy.
Added a new option `ui_config.metrics_proxy.path_allowlist`. This defaults to `["/api/v1/query", "/api/v1/query_range"]` when the metrics provider is set to `prometheus`.
Requests that do not use one of the allow-listed paths (via exact match) get a 403 Forbidden response instead.
This allows for client agent to be run in a more stateless manner where they may be abruptly terminated and not expected to come back. If advertising a per-agent reconnect timeout using the advertise_reconnect_timeout configuration when that agent leaves, other agents will wait only that amount of time for the agent to come back before reaping it.
This has the advantageous side effect of causing servers to deregister the node/services/checks for that agent sooner than if the global reconnect_timeout was used.
- Upgrade the ConfigEntry.ListAll RPC to be kind-aware so that older
copies of consul will not see new config entries it doesn't understand
replicate down.
- Add shim conversion code so that the old API/CLI method of interacting
with intentions will continue to work so long as none of these are
edited via config entry endpoints. Almost all of the read-only APIs will
continue to function indefinitely.
- Add new APIs that operate on individual intentions without IDs so that
the UI doesn't need to implement CAS operations.
- Add a new serf feature flag indicating support for
intentions-as-config-entries.
- The old line-item intentions way of interacting with the state store
will transparently flip between the legacy memdb table and the config
entry representations so that readers will never see a hiccup during
migration where the results are incomplete. It uses a piece of system
metadata to control the flip.
- The primary datacenter will begin migrating intentions into config
entries on startup once all servers in the datacenter are on a version
of Consul with the intentions-as-config-entries feature flag. When it is
complete the old state store representations will be cleared. We also
record a piece of system metadata indicating this has occurred. We use
this metadata to skip ALL of this code the next time the leader starts
up.
- The secondary datacenters continue to run the old intentions
replicator until all servers in the secondary DC and primary DC support
intentions-as-config-entries (via serf flag). Once this condition it met
the old intentions replicator ceases.
- The secondary datacenters replicate the new config entries as they are
migrated in the primary. When they detect that the primary has zeroed
it's old state store table it waits until all config entries up to that
point are replicated and then zeroes its own copy of the old state store
table. We also record a piece of system metadata indicating this has
occurred. We use this metadata to skip ALL of this code the next time
the leader starts up.
And into token.Store. This change isolates any awareness of token
persistence in a single place.
It is a small step in allowing Agent.New to accept its dependencies.
This might be better handled by allowing configuration for the InMemSink interval and retail, and disabling
the global. For now this is a smaller change to remove the goroutine leak caused by tests because go-metrics
does not provide any way of shutting down the global goroutine.
With this change, Agent.New() accepts many of the dependencies instead
of creating them in New. Accepting fully constructed dependencies from
a constructor makes the type easier to test, and easier to change.
There are still a number of dependencies created in Start() which can
be addressed in a follow up.
Previsouly it was done in Agent.Start, which is much later then it needs to be.
The new 'dns' package was required, because otherwise there would be an
import cycle. In the future we should move more of the dns server into
the dns package.
- unexport testing shims, and document their purpose
- resolve a TODO by moving validation to NewBuilder and storing the one
field that is used instead of all of Options
- create a slice with the correct size to avoid extra allocations
This is a small step to allowing Agent to accept its dependencies
instead of creating them in New.
There were two fields in autoconfig.Config that were used exclusively
to load config. These were replaced with a single function, allowing us
to move LoadConfig back to the config package.
Also removed the WithX functions for building a Config. Since these were
simple assignment, it appeared we were not getting much value from them.
