-- `--account ACCOUNT_NAME` - Specify the account name to use for the volume that stores the home directory data. Defaults to the current user's username.
-- `--user CONTAINER_USERNAME` - Specify the username to use inside the container. Defaults `ubuntu`.
-- `container CLI arguments...` - Any additional arguments are passed to the container CLI command (not the command inside the container).
+List all containers created by this script.

+```text
+azure-cli [(-a|--account) <account_name>]
