Migrating from self-hosted in Kubernetes Databases to managed hosted at Digital Ocean or the story of how I started working on Opportunistic TLS in ReactPHP

One of the things I’ve been planning for months, is to move my self-hosted Redis, PostgreSQL, and MySQL servers from hosting it inside my Kubernetes cluster to managed hosted at DigitalOcean. At $15 each, I would have to save at least $45 on Kubernetes cluster resources (nodes and volumes) by moving them. In the end, I succeeded at that and probably will end up saving even more as I’m moving some Prometheus exporters for certain things into my home Kubernetes cluster. (Less expensive per month to run and not super important to have a high uptime/availability, to be honest.) Plus I’ve been cutting down on services. On the plus side it comes with shiny graphs to look inside how the managed databases are doing

Building a kubernetes homelab with Raspberry Pi and Lego: Persistent Data Storage for PVC's

While most apps are stateless, the often do need to store state somewhere. In Kubernetes you can use a Persistent Volume Claim. That claims a piece of storage for the pod for now and in the future.

Building a kubernetes homelab with Raspberry Pi and Lego: Table of contents

For years I've been using Raspberry Pi's to do in home automation. One of the major constraints was maintenance, if one goes down I have to look at it while things are down. This made running Home Assistant less than ideal. After working with Kubernetes for a few years I decided to bring it into my home permanently. But with a challenge, by using Lego. During the Pandemic we got back into building Lego and this is a way for me to bring my Lego skills to the next level.

The post is probably the most boring one as it is the table of contents. However, it will be updated every time a new post is published. Also, posts won't be written in a logical order but more in order of the things that are already done. As such the "Home Assistant" post will come before the "Node Software set up" post because the former can be done again without changes or data loss due to the "Terraform" and "Storage" posts.
