从连接到Docker容器的代码/命令行运行Ansible-Playbook

Question

I am using this:

Specify docker containers in /etc/ansible/hosts file

to run my ansible playbooks against a docker container.

But is there any way to avoid having a physical /etc/ansible/hosts file with the information about the container? Eg run it from code where this information can be configured?

I looked at:

Running ansible-playbook using Python API

but when looking at the answers I see variables pointing to physical files, eg:

inventory = Inventory(loader=loader, sources='/home/slotlocker/hosts2')
playbook_path = '/home/slotlocker/ls.yml'

So not really sure why that is better than simply just calling from command line without using the Python ansible API.

Answer 1

May be install Ansible in Docker container and then run it locally inside the container. For example in the Dockerfile, include:

# Install Ansible
RUN pip install ansible
COPY ansible /tmp/ansible
# Run Ansible to configure the machine
RUN cd /tmp/ansible && ansible-playbook -i inventory/docker example_playbook.yml
