Created docker container not running bash

Question

I have a docker container that is not running bash. My docker command to create container was:

docker run -it -d -p 8088:80 containername centos:centos6

Which pulls docker image centos6 from hub. Then run docker start containername and returns the name of the container, which is on this example, containername.

If I do docker exec -it containername bash it says Container xxxxxx is not running, When I check on my docker app, it is shaded grey. Rerun docker start containername then docker ps -a it says Container exited 1 second ago.

I read somewhere that the -d (detached mode) will keep the container running but in this case, it does not. This docker run was already used on my computer but I had to reformat due to circumstances. Any help would be appreciated.

Answer 1

Your container runs all commands and stop his life. Try to create a Dockerfile with a sleep to keep it alive, like this:

FROM centos:centos6

CMD sleep infinity
