(command-juju-model-config)= # `juju model-config` > See also: [models](#models), [model-defaults](#model-defaults), [show-cloud](#show-cloud), [controller-config](#controller-config) ## Summary Displays or sets configuration values on a model. ## Usage ```juju model-config [options] [[=] ...]``` ### Options | Flag | Default | Usage | | --- | --- | --- | | `-B`, `--no-browser-login` | false | Do not use web browser for authentication | | `--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 | | `-m`, `--model` | | Model to operate in. Accepts [<controller name>:]<model name>|<model UUID> | | `--no-color` | false | Disable ANSI color codes in tabular output | | `-o`, `--output` | | Specify an output file | | `--reset` | | Reset the provided comma delimited keys | ## Examples Print the value of default-base: juju model-config default-base Print the model config of model mycontroller:mymodel: juju model-config -m mycontroller:mymodel Set the value of ftp-proxy to 10.0.0.1:8000: juju model-config ftp-proxy=10.0.0.1:8000 Set the model config to key=value pairs defined in a file: juju model-config --file path/to/file.yaml Set model config values of a specific model: juju model-config -m othercontroller:mymodel default-base=ubuntu@22.04 test-mode=false Reset the values of the provided keys to model defaults: juju model-config --reset default-base,test-mode ## Details To view all configuration values for the current model, run juju model-config You can target a specific model using the -m flag: juju model-config -m juju model-config -m : 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 model-config --format json juju model-config --format yaml To view the value of a single config key, run juju model-config key To set config values, run juju model-config key1=val1 key2=val2 ... You can also reset config keys to their default values: juju model-config --reset key1 juju model-config --reset key1,key2,key3 You may simultaneously set some keys and reset others: juju model-config key1=val1 key2=val2 --reset key3,key4 Config values can be imported from a yaml file using the --file flag: juju model-config --file=path/to/cfg.yaml This allows you to e.g. save a model's config to a file: juju model-config --format=yaml > cfg.yaml and then import the config later. Note that the output of model-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 model-config --file=cfg.yaml --ignore-read-only-fields You can also read from stdin using "-", which allows you to pipe config values from one model to another: juju model-config -c c1 --format=yaml \ | juju model-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. The default-series key is deprecated in favour of default-base e.g. default-base=ubuntu@22.04.
