Previously, the documentation linked to Golang's source code, which
can drift from the list of cipher suites supported by Consul. Consul
has a hard-coded mapping of string values to Golang cipher suites, so
this is a more direct source of truth to help users understand which
string values are accepted in the `tls_cipher_suites` configuration
value.
This avoids a conflict with #datacenter later on the page. We're mixing
histroic manually specified anchors with generated anchors (via
redcarpet / middleman-hashicorp) so we have to manually override the
automatic generation here.
I was tempted to rewrite the old manual anchors to use the automatic
generation, but there is no way to maintain backwards compatibility,
so will leave that for a time when it is appropriate for us to break
links (or redirect them, etc).
Fixes#3916
These was spotted in issue #3709.
These two configuration elements were renamed "serf_lan" and "serf_wan" in commit 12216583a1
Update documentation to fit the new code.
Note that flags "-serf-lan-bind" and "-serf-wan-bind" were not renamed.
* 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
* agent: add option to discard health output
In high volatile environments consul will have checks with "noisy"
output which changes every time even though the status does not change.
Since the output is stored in the raft log every health check update
unblocks a blocking call on health checks since the raft index has
changed even though the status of the health checks may not have changed
at all. By discarding the output of the health checks the users can
choose a different tradeoff. Less visibility on why a check failed in
exchange for a reduced change rate on the raft log.
* agent: discard output also when adding a check
* agent: add test for discard check output
* agent: update docs
* go vet
* Adds discard_check_output to reloadable config table.
* Updates the change log.
* Adds client-side retry for no leader errors.
This paves over the case where the client was connected to the leader
when it loses leadership.
* Adds a configurable server RPC drain time and a fail-fast path for RPCs.
When a server leaves it gets removed from the Raft configuration, so it will
never know who the new leader server ends up being. Without this we'd be
doomed to wait out the RPC hold timeout and then fail. This makes things fail
a little quicker while a sever is draining, and since we added a client retry
AND since the server doing this has already shut down and left the Serf LAN,
clients should retry against some other server.
* Makes the RPC hold timeout configurable.
* Reorders struct members.
* Sets the RPC hold timeout default for test servers.
* Bumps the leave drain time up to 5 seconds.
* Robustifies retries with a simpler client-side RPC hold.
* Reverts untended delete.
* Cleans up information about file extensions, now that they are required.
* Removes references to deprecated configuration options.
* Adds docs for multiple bind address support.
