Debugging Python Code

People on my team asked me some time ago how I debug things in our python code base. So I thought I’d share here.

The easiest (and least efficient) way to debug is to use print statements and logging. But since you’re not using a real debugger, you need to update the code and rerun in order to get new results.

Hence the most efficient way to debug things in python is to use a debugger. Don’t be scared, they are easy to master and they’ll serve you nicely for the rest of your life. They all are very similar.

Ansible and Podman Can Play Together Now

Sam Doran just merged my pull request which introduces a new connection plugin for podman. If you are not sure what an Ansible connection plugin is, hold tight and I’ll show you.

The connection plugin is the component which enables Ansible to execute commands in a target environment: you are probably mostly familiar with these two:

  • ssh — managing remote machines
  • local — executing a playbook in the current environment

Since Ansible abstracts this mechanic very well, you can easily write connection plugins for such a thing as container managers. Ansible has one for docker and some time ago I wrote one for buildah. I concluded it’s time to write it for podman as well, finally (so I can utilize it in ansible-bender).
