$ docker exec -u 0 -it <CONTAINER ID> /bin/bash

⁠Execute adhoc commands through the container

⁠Using the built image described above

$ docker run  --rm  -v ~/.ssh:/ssh --env-file .env provisioning "ansible-playbook files/playbook.yml -i files/hosts && ssh docker-node 'cat hello-world.txt'"

⁠using the latest pre-built image available on docker-hub

$ docker run  --rm  -v ~/.ssh:/ssh --env-file .env arranbartish/provisioning "ansible-playbook files/playbook.yml -i files/hosts && ssh docker-node 'cat hello-world.txt'"

You can mount custom inventory and playbooks in a volume and use them from the same image.

$ docker run  --rm  -v ~/.ssh:/ssh -v ~/dev/provisioning/files:/files --env-file .env arranbartish/provisioning "ansible-playbook /files/playbook.yml -i /files/hosts && ssh docker-node 'cat hello-world.txt'"
