`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¶

To view the value of a single config key for the current controller:

juju controller-config <key>

To view the value of all config keys for the current controller in the json format:

juju controller-config --format json

To view the values of all config keys for a different controller:

juju controller-config -c <controller>

To set two keys in the current controller to a different value:

juju controller-config <key>=<value> <key>=<value>

To save a controller’s current config to a yaml file:

juju controller-config --format=yaml > <configuration-filename>.yaml

To set the current controller’s config from a yaml file ignoring read-only fields, then override the value for one key:

juju controller-config --file path/to/file.yaml --ignore-read-only-fields <key>=<value>

To view all the configs from one file in yaml, then apply the same config values to another controller from stdin using | and - (in --file=-):

juju controller-config -c <controller> --format=yaml \
  | juju controller-config -c <controller> --file=- --ignore-read-only-fields
