Change the port for the existing container

You can change the port mapping by directly editing the hostconfig.json file at /var/lib/docker/containers/[hash_of_the_container]/hostconfig.json or /var/snap/docker/common/var-lib-docker/containers/[hash_of_the_container]/hostconfig.json, I believe, if You installed Docker as a snap.

You can determine the [hash_of_the_container] via the docker inspect <container_name> command and the value of the "Id" field is the hash.

  1. Stop the container (docker stop <container_name>).
  2. Stop docker service (per Tacsiazuma's comment)
  3. Change the file.
  4. Restart your docker engine (to flush/clear config caches).
  5. Start the container (docker start <container_name>).

Clear

	docker system df   # show disk space about docker
	docker image prune -f # clear all images which is not used

Print Logs

# print the log for container
docker logs -f <container-name> 1>/dev/null
