Run ansible-playbook in Jenkins container - docker

Question

Question: Is it possible to have a docker-compose file to run ansible-playbook in a Jenkins container?
Summary:
I have a Jenkins container (containerA) that I would like to run ansible-playbook. However, since the containers stop after the execution, I don't know how to define a non-running container in docker-compose.
I have posted the output for docker ps -a, the docker-compose and the Dockerfile for ansible-playbook
Please let me know if my question is unclear.

Answer 1

the docker container will be up only if there is any process or service that is holding that container to run.
In your docker file you are executing ansible-playbook command this will error out stating ERROR! You must specify a playbook file to run along with the help options.
If you want to execute ansible playbook you have to pass more arguments
A successful playbook execution happens like.
ansible-playbook -i <inventory_file> <playbook_name>
