   docker volume rm $(docker volume ls -q -f dangling=true)
+===== Connect to different docker daemon running on different port =====
+Example connecting to [[wiki:dockerized_jenkins_install_docker_via_ansible_dind|Dockerized jenkins install with docker in docker via ansible (dind)]] listening on 2376 port on host
+  docker -H tcp://localhost:2376 version
+You will get error //Error response from daemon: Client sent an HTTP request to an HTTPS server//. You have to point the docker client to use the certificates e.g.
+  docker --tlsverify --tlscacert=/var/lib/docker/volumes/build-server_jenkins-docker-certs/_data/ca.pem --tlscert=/var/lib/docker/volumes/build-server_jenkins-docker-certs/_data/cert.pem --tlskey=/var/lib/docker/volumes/build-server_jenkins-docker-certs/_data/key.pem -H tcp://localhost:2376 ps
+===== How to determine what containers use the docker volume? =====
+  docker ps -a --filter volume=VOLUME_NAME_OR_MOUNT_POINT
+===== Remove images older than 2 weeks =====
+  docker image prune -a --filter "until=336h" && docker system prune --filter "until=336h"
+The second command removes dangling build cache which will reclaim the disk space after image deletion.
+===== Print IPs for all containers =====
+  docker ps -a --format "table {{.ID}}\t{{.Names}}\t{{.Image}}" \
+  | tail -n +2 \
+  | while read -r id name image; do
+    ip=$(docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' "$id")
+    printf "%-12s\t%-30s\t%-20s\t%s\n" "$id" "$name" "$image" "${ip:-<no‑IP>}"
+  done
