Ansible Docker container image

The goal of this project is to provide an up-to-date version of Ansible and agru that people can run in a (Docker) container.

This project was created for spantaleev/matrix-docker-ansible-deploy (see Using Ansible via Docker).

Building

If you need to build it yourself, instead of using the ghcr.io/devture/ansible image that we publish to Docker Hub.

docker build -t ghcr.io/devture/ansible:latest -f Dockerfile .

Usage

Usage against a remote SSH host

If you can connect to the remote server using SSH, use the following command:

cd /some/ansible-project

docker run
-it \
--rm \
-w /work \
--mount type=bind,src=`pwd`,dst=/work \
--mount type=bind,src$HOME/.ssh/id_ed25519,dst=/root/.ssh/id_ed25519,ro \
--entrypoint=/bin/sh \
ghcr.io/devture/ansible:latest

You can execute ansible-playbook commands as per normal now.

Usage against the same host

If you'd like to run Ansible in a container on the server, and then target that same server from inside the container, use this:

cd /some/ansible-project

docker run
-it \
--rm \
--privileged \
--pid=host \
-w /work \
--mount type=bind,src=`pwd`,dst=/work \
--entrypoint=/bin/sh \
ghcr.io/devture/ansible:latest

When invoking the ansible-playbook commands, ensure that:

• you either add --connection=community.docker.nsenter to the command (e.g. ansible-playbook --connection=community.docker.nsenter ...)

• or that you've set ansible_connection=community.docker.nsenter for each host that needs it in your Ansible hosts file
