Usage: consul validate [options] FILE_OR_DIRECTORY...
|
|
|
|
Performs a thorough sanity test on Consul configuration files. For each file
|
|
or directory given, the validate 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.
|
|
|
|
Returns 0 if the configuration is valid, or 1 if there are problems.
