 A [default configuration](defaults/main.yml) is provided in this role. It establishes a cache service based on the freedesktop-sdk buildbox-casd Docker image with persistent storage. The following variables are defined:
 
 - `casd_cache`: the path to the cache on the host
+- `casd_docker_host`: The path (or address) to use to connect to the docker API, can be used for example to run the container with podman
 - `casd_image`: the Docker image to use in instantiating the container
 - `casd_container`: the container name
 - `casd_network`: the name of the Docker network to create and attach the service container to
 - `casd_network_connected_containers`: a list of containers to connect to the network being created for buildbox-casd
+- `casd_log_driver`: the log driver to use for the buildbox-casd container
+- `casd_log_options`: additional options to pass to the log driver
 - `casd_port`: the port the service listens to in the container and which is exposed on the container
 - `casd_published_ports`: a list of docker port specifications to be published. This does not affect whether the port on which buildbox-casd is listening is exposed.
 - `casd_bind_address`: the address the service listens to inside the container
