The `consul validate` command tests that config files are valid by attempting
|
|
|
|
|
to parse them. Useful to ensure a configuration change will not cause consul
|
|
|
|
|
to fail after a restart.

# Consul Validate
|

|
|
|
The `consul validate` command performs a thorough sanity test on Consul
|
|
|
|
|
configuration files. For each file or directory given, the command will
|
|
|
|
|
attempt to parse the contents just as the `consul agent` command would,
|
|
|
|
|
and catch any errors.
|
|
|
|
|
|
|
|
|
|
This is useful to do a test of the configuration only, without actually
|
|
|
|
|
starting the agent. This performs all of the validation the agent would, so
|
|
|
|
|
this should be given the complete set of configuration files that are going
|
|
|
|
|
to be loaded by the agent. This command cannot operate on partial
|
|
|
|
|
configuration fragments since those won't pass the full agent validation.
