How to continue a Docker container which has exite

问题:

Consider:

docker run -it centos /bin/bash

I pressed Ctrl+D to exit it.

I want to continue to run this container, but I found I can't.

The only method is

docker commit `docker ps -q -l` my_image
docker run -it my_image /bin/bash

Am I right? Is there a better method? (I'm using docker 0.8.0.)

回答1:

You can restart an existing container after it exited and your changes are still there.

docker start  `docker ps -q -l` # restart it in the background
docker attach `docker ps -q -l` # reattach the terminal & stdin

回答2:

docker start -a -i `docker ps -q -l`

Explanation:

docker start start a container (requires name or ID)
-a attach to container
-i interactive mode
docker ps List containers
-q list only container IDs
-l list only last created container

回答3:

Use:

docker start $(docker ps -a -q --filter "status=exited")

This will start all containers which are in the exited state.

docker exec -it <container-id> /bin/bash

This will connect to the particular container.

回答4:

If you want to do it in multiple, easy-to-remember commands:

1. list stopped containers:

docker ps -a

2. copy the name or the container id of the container you want to attach to, and start the container with:

docker start -i <name/id>

The -i flag tells docker to attach to the container's stdin.

If the container wasn't started with an interactive shell to connect to, you need to do this to run a shell:

docker start <name/id>
docker exec -it <name/id> /bin/sh

The /bin/sh is the shell usually available with alpine-based images.

If you want to continue exactly one Docker container with a known name:

docker start  `docker ps -a -q --filter "name=elas"`

回答6:

Follow these steps:

1. Run below command to see that all the container services both running and stopped on. Option -a is given to see that the container stops as well

   docker ps -a
   

2. Then start the docker container either by container_id or container tag names

   docker start <CONTAINER_ID> or <NAMES>
   

   

   Say from the above picture, container id 4b161b302337
   So command to be run is

   docker start 4b161b302337
   

3. One can verify whether the container is running with

   docker ps
   

回答7:

If you have a named container then it can be started by running

docker container start container_name

where container_name is name of the container that must be given at the time of creating container. You can replace container_name with the container id in case the container is not named. The container ID can be found by running:

docker ps -a

回答8:

These commands will work for any container (not only last exited ones). This way will work even after your system has rebooted. To do so, these commands will use "container id".

Steps:

1. List all dockers by using this command and note the container id of the container you want to restart: docker ps -a

2. Start your container using container id: docker start <container_id>

3. Attache and run your container: docker attach <container_id>

NOTE: I had tried this with linux system

Hope this helps someone!

回答9:

docker start `docker ps -a | awk '{print $1}'`

This will start up all the containers that are in the 'Exited' state
