Mastodon

Welcome to Larvitz Blog! I’m Christian, a Cloud Consultant by day and FreeBSD enthusiast by night, with over 20 years in enterprise IT. Here I write about FreeBSD jails, PF firewalling, self-hosting, Linux system administration, and anything that’s cleanly engineered. Most articles are hands-on guides born from running my own infrastructure, from dual-stack networking and Ansible automation to hosting a Mastodon instance on FreeBSD.

Have a question or want to discuss something? Find me on the Fediverse at @Larvitz@burningboard.net. I’m always happy to chat!

Reproducible Ansible with Execution Environments

A “control node” with a hand-curated venv works. Until it doesn’t. A colleague has different collection versions, CI installs a slightly newer Python library, and a playbook that ran yesterday now fails. Execution Environments turn the control node into a versioned container image. ansible-builder produces it, ansible-navigator runs against it, and the same artifact ships from your laptop into AAP/AWX without modification.
