The config commands are used for managing container configuration. The configuration data is edited in two stages. First the changes are queued until they are dynamically loaded into the container by executing the config:update command. A copy of the configuration is persisted to the file system in the container's etc folder.
When editing a configuration the commands are used as follows:
Start the editing session for the specified configuration.
Edits, or creates, a configuration.
Lists the properties in the configuration.
Append a new property to the configuration.
Sets the value for a configuration property.
Deletes a property from the configuration.
Saves the changes and updates the containers using the configuration.
You can abandon an editing session using config:cancel.
Type config: then press Tab at the prompt to view the available commands.
