To ease the transition for users, the original gRPC
port can still operate in a deprecated mode as either
plain-text or TLS mode. This behavior should be removed
in a future release whenever we no longer support this.
The resulting behavior from this commit is:
`ports.grpc > 0 && ports.grpc_tls > 0` spawns both plain-text and tls ports.
`ports.grpc > 0 && grpc.tls == undefined` spawns a single plain-text port.
`ports.grpc > 0 && grpc.tls != undefined` spawns a single tls port (backwards compat mode).

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.
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.
The nil value was never used. We can avoid a bunch of complications by
making the field a string value instead of a pointer.
This change is in preparation for fixing a silent config failure.
Flags is an overloaded term in this context. It generally is used to
refer to command line flags. This struct, however, is a data object
used as input to the construction.
It happens to be partially populated by command line flags, but
otherwise has very little to do with them.
Renaming this struct should make the actual responsibility of this struct
more obvious, and remove the possibility that it is confused with
command line flags.
This change is in preparation for adding additional fields to
BuilderOpts.
This field was populated for one reason, to test that it was empty.
Of all the callers, only a single one used this functionality. The rest
constructed a `Flags{}` struct which did not set Args.
I think this shows that the logic was in the wrong place. Only the agent
command needs to care about validating the args.
This commit removes the field, and moves the logic to the one caller
that cares.
Also fix some comments.
Based on work done in https://github.com/hashicorp/memberlist/pull/196
this allows to restrict the IP ranges that can join a given Serf cluster
and be a member of the cluster.
Restrictions on IPs can be done separatly using 2 new differents flags
and config options to restrict IPs for LAN and WAN Serf.
This is like a Möbius strip of code due to the fact that low-level components (serf/memberlist) are connected to high-level components (the catalog and mesh-gateways) in a twisty maze of references which make it hard to dive into. With that in mind here's a high level summary of what you'll find in the patch:
There are several distinct chunks of code that are affected:
* new flags and config options for the server
* retry join WAN is slightly different
* retry join code is shared to discover primary mesh gateways from secondary datacenters
* because retry join logic runs in the *agent* and the results of that
operation for primary mesh gateways are needed in the *server* there are
some methods like `RefreshPrimaryGatewayFallbackAddresses` that must occur
at multiple layers of abstraction just to pass the data down to the right
layer.
* new cache type `FederationStateListMeshGatewaysName` for use in `proxycfg/xds` layers
* the function signature for RPC dialing picked up a new required field (the
node name of the destination)
* several new RPCs for manipulating a FederationState object:
`FederationState:{Apply,Get,List,ListMeshGateways}`
* 3 read-only internal APIs for debugging use to invoke those RPCs from curl
* raft and fsm changes to persist these FederationStates
* replication for FederationStates as they are canonically stored in the
Primary and replicated to the Secondaries.
* a special derivative of anti-entropy that runs in secondaries to snapshot
their local mesh gateway `CheckServiceNodes` and sync them into their upstream
FederationState in the primary (this works in conjunction with the
replication to distribute addresses for all mesh gateways in all DCs to all
other DCs)
* a "gateway locator" convenience object to make use of this data to choose
the addresses of gateways to use for any given RPC or gossip operation to a
remote DC. This gets data from the "retry join" logic in the agent and also
directly calls into the FSM.
* RPC (`:8300`) on the server sniffs the first byte of a new connection to
determine if it's actually doing native TLS. If so it checks the ALPN header
for protocol determination (just like how the existing system uses the
type-byte marker).
* 2 new kinds of protocols are exclusively decoded via this native TLS
mechanism: one for ferrying "packet" operations (udp-like) from the gossip
layer and one for "stream" operations (tcp-like). The packet operations
re-use sockets (using length-prefixing) to cut down on TLS re-negotiation
overhead.
* the server instances specially wrap the `memberlist.NetTransport` when running
with gateway federation enabled (in a `wanfed.Transport`). The general gist is
that if it tries to dial a node in the SAME datacenter (deduced by looking
at the suffix of the node name) there is no change. If dialing a DIFFERENT
datacenter it is wrapped up in a TLS+ALPN blob and sent through some mesh
gateways to eventually end up in a server's :8300 port.
* a new flag when launching a mesh gateway via `consul connect envoy` to
indicate that the servers are to be exposed. This sets a special service
meta when registering the gateway into the catalog.
* `proxycfg/xds` notice this metadata blob to activate additional watches for
the FederationState objects as well as the location of all of the consul
servers in that datacenter.
* `xds:` if the extra metadata is in place additional clusters are defined in a
DC to bulk sink all traffic to another DC's gateways. For the current
datacenter we listen on a wildcard name (`server.<dc>.consul`) that load
balances all servers as well as one mini-cluster per node
(`<node>.server.<dc>.consul`)
* the `consul tls cert create` command got a new flag (`-node`) to help create
an additional SAN in certs that can be used with this flavor of federation.
* Add ui-content-path flag
* tests complete, regex validator on string, index.html updated
* cleaning up debugging stuff
* ui: Enable ember environment configuration to be set via the go binary at runtime (#5934)
* ui: Only inject {{.ContentPath}} if we are makeing a prod build...
...otherwise we just use the current rootURL
This gets injected into a <base /> node which solves the assets path
problem but not the ember problem
* ui: Pull out the <base href=""> value and inject it into ember env
See previous commit:
The <base href=""> value is 'sometimes' injected from go at index
serve time. We pass this value down to ember by overwriting the ember
config that is injected via a <meta> tag. This has to be done before
ember bootup.
Sometimes (during testing and development, basically not production)
this is injected with the already existing value, in which case this
essentially changes nothing.
The code here is slightly abstracted away from our specific usage to
make it easier for anyone else to use, and also make sure we can cope
with using this same method to pass variables down from the CLI through
to ember in the future.
* ui: We can't use <base /> move everything to javascript (#5941)
Unfortuantely we can't seem to be able to use <base> and rootURL
together as URL paths will get doubled up (`ui/ui/`).
This moves all the things that we need to interpolate with .ContentPath
to the `startup` javascript so we can conditionally print out
`{{.ContentPath}}` in lots of places (now we can't use base)
* fixed when we serve index.html
* ui: For writing a ContentPath, we also need to cope with testing... (#5945)
...and potentially more environments
Testing has more additional things in a separate index.html in `tests/`
This make the entire thing a little saner and uses just javascriopt
template literals instead of a pseudo handbrake synatx for our
templating of these files.
Intead of just templating the entire file this way, we still only
template `{{content-for 'head'}}` and `{{content-for 'body'}}`
in this way to ensure we support other plugins/addons
* build: Loosen up the regex for retrieving the CONSUL_VERSION (#5946)
* build: Loosen up the regex for retrieving the CONSUL_VERSION
1. Previously the `sed` replacement was searching for the CONSUL_VERSION
comment at the start of a line, it no longer does this to allow for
indentation.
2. Both `grep` and `sed` where looking for the omment at the end of the
line. We've removed this restriction here. We don't need to remove it
right now, but if we ever put the comment followed by something here the
searching would break.
3. Added `xargs` for trimming the resulting version string. We aren't
using this already in the rest of the scripts, but we are pretty sure
this is available on most systems.
* ui: Fix erroneous variable, and also force an ember cache clean on build
1. We referenced a variable incorrectly here, this fixes that.
2. We also made sure that every `make` target clears ember's `tmp` cache
to ensure that its not using any caches that have since been edited
everytime we call a `make` target.

* remove contentpath from redirectFS struct
* Support for maximum size for Output of checks
This PR allows users to limit the size of output produced by checks at the agent
and check level.
When set at the agent level, it will limit the output for all checks monitored
by the agent.
When set at the check level, it can override the agent max for a specific check but
only if it is lower than the agent max.
Default value is 4k, and input must be at least 1.

These options allow for a finer control over when script checks are enabled by
giving the option to only allow them when they are declared from the local
file system.

* config: refactor ReadPath(s) methods without side-effects
Return the sources instead of modifying the state.
* config: clean data dir before every test
* config: add tests for config-file and config-dir
* config: add -config-format option
Starting with Consul 1.0 all config files must have a '.json' or '.hcl'
extension to make it unambigous how the data should be parsed. Some
automation tools generate temporary files by appending a random string
to the generated file which obfuscates the extension and prevents the
file type detection.
This patch adds a -config-format option which can be used to override
the auto-detection behavior by forcing all config files or all files
within a config directory independent of their extension to be
interpreted as of this format.
Fixes#3620
The `consul agent` command was ignoring extra command line arguments
which can lead to confusion when the user has for example forgotten to
add a dash in front of an argument or is not using an `=` when setting
boolean flags to `true`. `-bootstrap true` is not the same as
`-bootstrap=true`, for example.
Since all command line flags are known and we don't expect unparsed
arguments we can return an error. However, this may make it slightly
more difficult in the future if we ever wanted to have these kinds of
arguments.
Fixes#3397
* new config parser for agent
This patch implements a new config parser for the consul agent which
makes the following changes to the previous implementation:
* add HCL support
* all configuration fragments in tests and for default config are
expressed as HCL fragments
* HCL fragments can be provided on the command line so that they
can eventually replace the command line flags.
* HCL/JSON fragments are parsed into a temporary Config structure
which can be merged using reflection (all values are pointers).
The existing merge logic of overwrite for values and append
for slices has been preserved.
* A single builder process generates a typed runtime configuration
for the agent.
The new implementation is more strict and fails in the builder process
if no valid runtime configuration can be generated. Therefore,
additional validations in other parts of the code should be removed.
The builder also pre-computes all required network addresses so that no
address/port magic should be required where the configuration is used
and should therefore be removed.
