Usage: consul configtest [options]
|

|

|
|
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.
|
||
|
|
|
||
|
|
Options:
|
||
|
|
|
||
|
|
-config-file=foo Path to a JSON file to read configuration from.
|
||
|
|
This can be specified multiple times.
|
||
|
|
-config-dir=foo Path to a directory to read configuration files
|
||
|
|
from. This will read every file ending in ".json"
|
||
|
|
as configuration in this directory in alphabetical
|
||
|
