Docker – Some Commands

To run the docker with host port matching and with mounts

#docker run -tiP -p 0.0.0.0:: -v :

To get to console of running container

#docker exec -ti  /bin/bash

To get the host ports which docker ports are bind to- check DOCKER chain

Ref: https://docs.docker.com/engine/reference/commandline/inspect/

[root@ip-172-31-35-29 ~]# docker inspect --format='{{range $p, $conf := .NetworkSettings.Ports}} {{$p}} -> {{(index $conf 0).HostPort}} {{end}}' 8d0d0a2e4539
 8153/tcp -> 32772  8154/tcp -> 32771
[root@ip-172-31-35-29 ~]#

Docker CLI – https://docs.docker.com/engine/reference/commandline/docker/#child-commands

I was not able to share host mount to docker mount eventhough I am trying – “docker run -v : ” . Reading through https://forums.docker.com/t/docker-fails-to-mount-v-volume-from-nfs-mounted-directory/582/8 found that restarting docker service worked strangely.

Below section gives the commands on how to clean up – delete exited containers and images and deleting the volumes.
