Podman (docker) container

Question

Does someone know how to start and stop services inside the container?

E.g. wish to stop sshd service INSIDE the Ubuntu container, but not in the whole host (RHEL).

Have you checked this issue on serverfault? https://serverfault.com/questions/724553/how-to-prevent-attach-or-exec-in-a-docker-container — JustLudo, Nov 19 '20 at 08:34
A Docker container runs one process; it does not run "services" _per se_, and commands like `service` don't usually work. — David Maze, Nov 19 '20 at 11:11

you need to get a root shell in the container with docker exec -it <container_name> /bin/bash then you can run the command that you want

I can't! this is the problem. in Centos (RHEL based) all the containers are running without their own kernels – J. Doe Nov 19 '20 at 19:24
Are you sure sshd is running? – Kroustou Nov 19 '20 at 20:19

Log in to the container using the below command

docker exec -it <container_id> /bin/bash
Using any of the below commands can stop the ssh service

$ sudo /etc/init.d/ssh stop or $ sudo service ssh stop or $ sudo systemctl stop ssh

The problem is that I'm using Centos. It says that `root@3904ba96d9b2:/# /etc/init.d/ssh start bash: /etc/init.d/ssh: No such file or directory` – J. Doe Nov 19 '20 at 19:22
