Kamal DevOps
The course
This is a 2:30h long and practical course explaining what Kamal is and how it fits the wider ecosystem of platform tools.
There are two videos:
- Part 1: Kamal theory talking about connectivity, networking, infrastructure, system configuration and how it all fits together with Kamal. Length is around 1:30h.
- Part 2: Kamal practice deploying two applications (one SQLite and one on PostgreSQL with monitoring). Length is around 1:00h.
You can download both videos to your computer and watch them offline at convenient time (take them on the airplane!). Both videos have markers for sections they contain.
What you’ll learn
Connectivity and networking - How to deploy Kamal application with SSH or with a Tailscale VPN.
Infrastructure - How to deploy Kamal manually or with Terraform on Hetzner and optionally fronted by Cloudflare proxy.
