ansible-role-docker VS ansible.traefik

In this case, yeah sure, go ahead. Looks fine. But is the package really not available at all or rather called differently? (from my perspective packages named equally across a wide range of distros / package managers aren't to common) In the later case you would / could load a var file with a variable which contains distro-specific package names for Redhat and just reference the variable in your install task. (see for example https://github.com/geerlingguy/ansible-role-docker/blob/master/tasks/main.yml#L2 and https://github.com/geerlingguy/ansible-role-docker/tree/master/vars)

To install docker, there's multiple examples to find, I'd start with this role : https://github.com/geerlingguy/ansible-role-docker

You might want to check out https://github.com/geerlingguy/ansible-role-docker

before writing a playbook, check for an existing role to do the work for you

This might not be the answer you're looking for, but geerlingguy.docker is pretty good

I mark bugs, security-related issues, and planned features with appropriate labels, and the stale bot ignores those: https://github.com/geerlingguy/ansible-role-docker/blob/mast...

Not all maintainers do the same. And some even _lock issues_, which I hate, because even closed issues can have a very fruitful discussion long after the issue was originally posted.

As a teaching example, installing your own docker this way might be good.But it would be better to install using a role. One you design yourself, or even better use an existing role like geerlingguy.docker.

I use ansible to setup the docker VMs after provisioning (https://github.com/geerlingguy/ansible-role-docker)

PS. As a slight sidenote, I just wanted to thank you for your (many!) Ansible roles - today I was able to run Docker in Ansible in my side project because of your docker ansible role to investigate Opensearch. Just wanted to say thanks you very much
