Commands

A full reference can be viewed at https://docs.docker.com/reference/cli/docker/

Images

List all available image tags

$ docker images

Volumes

List local mount points of a running container

$ docker inspect -f '{{ .Mounts }}' <CONTAINER_NAME>

Logs

Display log messages (follow latest):

$ docker logs --follow <CONTAINER_NAME>

Follow incoming log messages (but don’t show previous):

$ docker logs --tail=0 --follow <CONTAINER_NAME>

Save all previous logs to file (no file logging driver configured, container must still run):

$ docker logs <CONTAINER_NAME> 2> file.log

Important

The command does not catch logs arriving after executing the command.

Log saving location

(default logging driver is JSON)

• Docker: /var/lib/docker/containers/<container_id>/<CONTAINER_ID>-json.log

• Rootless Docker: ~/.local/share/docker/containers/<CONTAINER_ID>/<CONTAINER_ID>-json.log

The beginning of the container ID can be retrieved via docker container ls.

You may also retrieve the filepath by running:

$ docker inspect <CONTAINER_NAME> | jq -r .[].LogPath
