How to Continue a Docker Container Which Has Exited
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...
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.)

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
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
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.
If you want to do it in multiple, easy-to-remember commands:
- list stopped containers:
docker ps -a
- 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"`
Follow these steps:
Run below command to see that all the container services both running and stopped on. Option
-ais given to see that the container stops as welldocker ps -aThen start the docker container either by
container_idor container tag namesdocker start <CONTAINER_ID> or <NAMES>Say from the above picture, container id 4b161b302337
So command to be run isdocker start 4b161b302337One can verify whether the container is running with
docker ps
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
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:
List all dockers by using this command and note the container id of the container you want to restart:
docker ps -aStart your container using container id:
docker start <container_id>Attach and run your container:
docker attach <container_id>
NOTE: Works on linux
by name
sudo docker start bob_the_container
or by Id
sudo docker start aa3f365f0f4e
this restarts stopped container, use -i to attach container's STDIN or instead of -i you can attach to container session (if you run with -it)
sudo docker attach bob_the_container
If you just want to start a container with status 'Exited', just type:
sudo docker start container_name
Without sudo. See more
docker start container_name
If container name doesn't work, replace the name to container id
Run your container with --privileged flag.
docker run -it --privileged ...
docker start `docker ps -a | awk '{print $1}'`
This will start up all the containers that are in the 'Exited' state
For those coming here in 2021 and beyond, the following command will do what the accepted answer will do in one line.
$ docker start -ai $(docker ps -q -l)
In my case, the docker container exits cleanly when I start it so none of the above worked. What I needed was a way to change the command to be run.
With docker-compose I was able to change the command by running:
docker-compose run <container name in docker-compose.yml> bash
e.g.
docker-compose run app bash
Note! This actually recreates the container, so it is not run on the previous instance.
