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.
