How to run Fedora CoreOS in lxc

Intro Link to heading

Fedora CoreOS advertises itself as container first OS, immutable, auto-updating, scalable, and secure. As I am beginning to learn Kubernetes, it looks like a perfect match. Regardless of if you prefer Fedora CoreOS, Flatcar Container Linux, or anything else, you first want to play with it in a local environment. In 2022 I switched from Windows 11 to Fedora, and I was searching for a lightweight solution to run Virtual Machines and Container OS - lxc / lxd feels like a great alternative to Oracle VirtualBox. Installing Ubuntu, Fedora or Alpine Linux is easy with lxc, however, what do you do if you want to run something different? Below you will find easy to follow instructions on how to add Fedora CoreOS image to lxc and how to launch it as VM in lxc.

Twirl in Scala Link to heading

Twirl is a type safe template engine based on Scala, and designed for Play Framework. It can also be used standalone, without Play. I will go through some information about Twirl, how to set it up, and use in a standalone Scala application.

Keep in mind:

Templates are compiled to a standard Scala functions. This provides type safety.
When used standalone in Scala, Twirl needs to be added as an SBT plugin (sbt-twirl), not as library dependency.
If you are using Intellij Idea please note that you will see Cannot resolve symbol until SBT compiles your templates. You can always run sbt compile
