Sigil Sorcery: Custom Sigils in Elixir
Elixir sigils are general-purpose tools for handling common data types. Examples of built-in sigils include strings (~s), regular expressions (~r), dates (~D), and lists of words (~w). But, as you might have guessed, Elixir’s flexibility doesn’t stop here; Elixir allows us to create custom sigils for specific needs, and that is what we’re doing now. […]
Cluster Creation – The Kubernetes Cluster DIY Pt. 4
After the preparation in the last few chapters we now start with the actual cluster creation. I think it’s best to just follow the instructions of this kube-hetzner-project on GitHub. Here are a couple of changes that I made, which I should create a pull request for: dotenv support terraform state tracking via Google Cloud […]
