Working with Kubernetes' recommended labels

Among Kubernetes' well-known labels, a subset of them are considered recommended. I have repeatedly tried to figure out what a good structure is, often when deploying resources in Kubernetes or when writing new manifests from scratch. But I frequently change my mind regarding what the right choices are and I am easily mislead by existing misguided choices.

This document is my attempt at finding a reasonable structure, hopefully easy to work with and flexible when it needs to be.

Backup requirements

Different applications have different requirements when it comes to being backed up. Some applications works perfectly fine if a disk snapshot is taken, while others may require to first enter some sort of maintenance mode first to ensure data consistency. These are my personal notes on what requirements different software stacks has. I make no promises that any of this is true. What I do promise you is that this is not an exhaustive list.

Splitting a repo

Here is a recepie for how to split a repo.

If you have a repo that you want to split in twine, life can be simple! At least if you have been a good boy and kept the different parts in different subdirectories to begin with…

This is all you have to do:
