An Ansible primer for DevOps: Infrastructure as Code, part 3

Ansible is highlighted as an essential tool for DevOps engineers due to its ability to simplify deployments across varying scales, from a single node to 100,000 nodes. The discussion focuses on integrating Ansible with Tailscale, utilizing Tailscale SSH to streamline identity and SSH key management, and deploying a DigitalOcean droplet with cloud-init and Terraform as part of an Infrastructure as Code (IaC) series. This deployment automatically enrolls the node into a Tailscale network and sets up a Jellyfin server to stream video via a Caddy reverse proxy without intermediaries. The video tutorial also demonstrates the use of Ansible’s Jinja2 templating engine to programmatically configure a Caddyfile for the reverse proxy on DigitalOcean. This content is part three of a series, with previous parts covering cloud-init basics and the combination of Terraform and cloud-init for automated cloud tailnet node creation, supported by open-sourced code and Tailscale documentation.
