Usage: nomad config validate <config_path> [<config_path...>]
|

|
|
|
||
|
|
Perform validation on a set of Nomad configuration files. This is useful
|
||
|
|
to test the Nomad configuration without starting the agent.
|
||
|
|
|
||
|
|
Accepts the path to either a single config file or a directory of
|
||
|
|
config files to use for configuring the Nomad agent. This option may
|
||
|
|
be specified multiple times. If multiple config files are used, the
|
||
|
|
values from each will be merged together. During merging, values from
|
||
|
|
files found later in the list are merged over values from previously
|
||
|
|
parsed files.
|
||
|
|
|
||
|
|
This command cannot operate on partial configuration fragments since
|
||
|
|
those won't pass the full agent validation. This command does not
|
||
|
|
require an ACL token.
|
||
|
|
|
||
|
|
Returns 0 if the configuration is valid, or 1 if there are problems.
