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 <model>
juju model-config -m <controller>:<model>

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.
