Usage: consul validate [options] FILE_OR_DIRECTORY...

|
|
Performs a basic 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.
|
|
|
|
Returns 0 if the configuration is valid, or 1 if there are problems.
