Execute ansible playbook on a docker container

Question

I'm trying to execute an ansible playbook on a docker container before running it on the actual platform(just to be safe). How do I do this? Can I please get a dockerfile for the same?

Hey @Ram, you could use a dockerfile something like this:

# Start with the ubuntu image
FROM ubuntu
# Update apt cache
RUN apt-get -y update
# Install ansible dependencies
RUN apt-get install -y python-yaml

 # Set variables for ansible
WORKDIR /tmp/ansible
ENV PATH /tmp/ansible/bin:/sbin:/usr/sbin:/usr/bin
ENV ANSIBLE_LIBRARY /tmp/ansible/library
ENV PYTHONPATH /tmp/ansible/lib:$PYTHON_PATH

 # add playbooks to the image. This might be a git repo instead
ADD playbooks/ /etc/ansible/
ADD inventory /etc/ansible/hosts
WORKDIR /etc/ansible

 # Run ansible using the site.yml playbook
RUN ansible-playbook /etc/ansible/site.yml -c local
