It's simple enough and I had some prior experience with it, so I merely have some variables, roles that render a docker-compose.yml.j2 template and boom. It all works, I have easy access to secrets, shared variables among stacks and run it with a simple `ansible-playbook` call.
If I forget/don't know the Ansible modules, Claude or their docs are really easy to use.
Every time I went down a bash script route I felt like I was re-inventing something like Ansible.
