Images are gone after using boot2docker for a few days

Hello,

I have been working with docker for about a week now. I am using boot2docker in a virtualbox with a ubuntu OS. Today, after a couple of days of non-use, I opened boot to docker, issued a

docker ps

command, and the containers are missing. The images are still there that I initially used to create the containers. I do not have any idea of how to trouble shoot this. Any suggestions would be appreciated.

The only thing I can think of is that I restarted my computer (I usually leave it on in the evening). Could that have caused the problem somehow?

Thanks,

Ivan

Hello,

It sounds like your VM has been rebooted. Docker will not start containers unless they were created with a restart policy.

By default docker ps only shows running containers. Run docker ps -a to show all containers (running and otherwise)

You can start stopped containers with the docker start command.

Hi Jeff,

Thanks very much for the reply. I found it there.

I will look into what restart policies are.

All the best,

Ivan
