Examples
Print all config values for the current controller:
juju controller-config
Print the value of “api-port” for the current controller:
juju controller-config api-port
Print all config values for the controller “mycontroller”:
juju controller-config -c mycontroller
Set the “auditing-enabled” and “audit-log-max-backups” keys:
juju controller-config auditing-enabled=true audit-log-max-backups=5
Set the current controller’s config from a yaml file:
juju controller-config --file path/to/file.yaml
Details
To view all configuration values for the current controller, run juju controller-config You can target a specific controller using the -c flag: juju controller-config -c By default, the config will be printed in a tabular format. You can instead print it in json or yaml format using the --format flag: juju controller-config --format json juju controller-config --format yaml
To view the value of a single config key, run juju controller-config key To set config values, run juju controller-config key1=val1 key2=val2 …
Config values can be imported from a yaml file using the --file flag: juju controller-config --file=path/to/cfg.yaml This allows you to e.g. save a controller’s config to a file: juju controller-config --format=yaml > cfg.yaml and then import the config later. Note that the output of controller-config may include read-only values, which will cause an error when importing later. To prevent the error, use the --ignore-read-only-fields flag: juju controller-config --file=cfg.yaml --ignore-read-only-fields
You can also read from stdin using “-”, which allows you to pipe config values
from one controller to another:
juju controller-config -c c1 --format=yaml
| juju controller-config -c c2 --file=- --ignore-read-only-fields
You can simultaneously read config from a yaml file and set config keys
as above. The command-line args will override any values specified in the file.
