Oracle want’s to participate in the open source movement lately, making itself known as “an Open Source company”. Part of this is the Oracle Database Operator for Kubernetes. It’s an early version (0.1.0) that I’ve tested out, so it offers only a limited set of features as of now. Let’s move it to it’s paces, shall we?

In an earlier blogpost, I wrote about doing Postgres backups using WAL-G to a S3 storage. This time we have a look to either clone or “inplace” restore a postgres instance from these backups. All of this using the Zalando Postgres Operator. If you haven’t done so, please read the backup post before proceeding reading this one.

Github Actions is a free CI/CD solution that comes along with every Github account. It enables you to test, build and deploy your code you push to your Github repository. When using a free (non-payed) Github account, it comes with some limitation though. Which you can workaround by using your own, selfhosted Actions runner host.

Some days ago I was pushed to the kind project. A leightweight possibility to build a Kubernetes cluster on top of Docker for easy and fast testing Kubernetes deployments. I’ve written an Ansible role to install kind and create / delete clusters as you need.

Storing sensitive or secret information within a Git repository is never a good idea, at least as long as you do it unencrypted. Whoever has access to the Git repository, can view and change this sensitive data. Storing encrypted data within a Git repo has also the downside, that you need to decrypt it while you want to work with the data and you have to remember to reencrypt it, before pushing it back again. Here comes git-crypt into play. Git-crypt gives you a transparent method to de- and encrypt data during pulling and pushing from or to your Git repository.

Doing basebackups of Postgres databases enables you to do a Point-in-time recovery (PITR) of your database. Doing backups for your databases that have been deployed using the Zalando Postgres Operator, is a different beast. Here I show you how it’s done with a MinIO (self)hosted S3 compatible Object Storage.

Wanting to have a S3 compatible Object Storage costs you money when ordering it with a Cloud provider out there. Self hosting it on your existing Homelab is for free and also fun to do. So let’s have a look into how to deploy MinIO Object Storage on your Docker environment.

If you’re forgetful like me, you have to wrote everything down to remember what you did later. For Docker, this hits me quite hard for every “docker run” command I’ve ever issued. What was the env setting like? On which port did I ran the container? I found a small little Python project called “docker-replay” quite useful to generate docker run commands out of running containers for me.
