By default, the `GET /containers/json` endpoint returns a list of all single containers in a space that are in a running state. To request a list of all containers independent of their current state, set the `all` query parameter to true. Allowed values are: `all=true`, `all=True`, and `all=1`.

You can filter your containers by any environment variable key or value that is listed in the `Env` section of your CLI/ API response when you run the `cf ic inspect <container>` command, or call the `GET /containers/{id}/json` endpoint. Your search criteria does not need to be an exact match. It can also be a part of the key or value you are looking for. For example, to filter all containers with an environment variable that contains `id` in one of their environment variables, use `filter=id`.
