commit container and re-run on docker.

After I commited container to image,
I run container by saved image again and add option to publish the container’s port(8888).

Command list

  • stop container
$ docker ps
$ docker container stop work
$ docker ps
  • commit container to image
$ docker container commit -m "add python3.5 and jupyter notebook" work xxxxxxx/centos7:python3
$ docker images
  • run container
$ docker container run -d --name work2 -p 18888:8888 xxxxxxx/centos7:python3 tail -f /dev/null
$ docker ps
$ docker exec -it work2 /bin/bash
