`juju controller-config`¶

See also: controllers, model-config, show-cloud

Summary¶

Displays or sets configuration settings for a controller.

Usage¶

juju controller-config [options] [<attribute key>[=<value>] ...]

Options¶

Flag	Default	Usage
`-B`, `--no-browser-login`	false	Do not use web browser for authentication
`-c`, `--controller`		Controller to operate in
`--color`	false	Use ANSI color codes in output
`--file`		path to yaml-formatted configuration file
`--format`	tabular	Specify output format (json\|tabular\|yaml)
`--ignore-read-only-fields`	false	Ignore read only fields that might cause errors to be emitted while processing yaml documents
`--no-color`	false	Disable ANSI color codes in tabular output
`-o`, `--output`		Specify an output file

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.
