On OS (CoreOS) restart Docker starts multiple containers

Question

I have my customer Docker container on a CoreOS OS host. I start my container using the docker run command as. follows:

docker run -d --restart always --net=host -p 8080:8080 --log-opt max-size=2mb my_docker_hub_accountname/imagename

And when I reboot the host I always see multiple images being run when I run the following command:

user@coreos-1 ~ $ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                  PORTS               NAMES

Is there a way to control so that I only have 1 image running instead of multiple images by the Docker container?

Answer 1

I was able to resolve this in one way.

I searched for all container using command:

docker ps -a

I had to remove all the other containers that were previously run using

docker rm $container_id

Now I only 1 docker image running in a container. I reboot and I only see 1 container running.

hope it helps another docker user.
