We need to properly backup and secure the application data which is typically stored in persistent volumes. On the other hand, we need to backup the etcd data because it is the operational data store that is used by Kubernetes in order to operate accordingly. In this post we are looking at how to schedule the etcd data backup using out of the box Kubernetes features.

K8s on RPi 4 Pt. 4 – Configuring Kubernetes Storage

Posted on by CK

In a perfect world, we would prefer to implement microservices to be stateless. This stateless approach eliminates a lot of problems towards maintaining the storage for the applications data. However, we are not in a perfect world. At most time, applications need to deal with data and keep them on storage for long term references. We need persistent storage solution so that the applications data can survive containers (or systems) restart or crash. Kubernetes provides this type of storage support in the concept of volumes. We are going to look at how can we configured storage for Kubernetes on Raspberry Pi 4.
