Sometimes, regardless of the possibilities offered by “the cloud”, you want to host important services yourself. For me as a software and DevOp engineer, this applies to my source code. For this reason, I host my GitLab instance myself. Since the GitLab package for DSM provided by Synology is outdated, I will explain here how to install the latest version of GitLab on a DiskStation using Docker.

For certain docker-driven services, I would like to check regularly for new versions. One way to do this is to query Docker Hub via Cronjob. Here I provide a little bash script to check for Docker image updates on Docker Hub.

In order to gain experience with a Kubernetes cluster or to be able to experiment with it, a functioning cluster is required. Since most conceptual challenges do not require a high performance test cluster, it is also sufficient to build a smaller and therefore more cost-effective one. For this reason I decided to set up a Raspberry Pi Kubernetes Cluster for testing purposes.
If the Raspberry Pis are not to be connected via WLAN but cable, the corresponding network components are also required:
The website of Hypriot has a very good tutorial how to set up a Kubernetes cluster with Raspberry Pi boards: https://blog.hypriot.com/post/setup-kubernetes-raspberry-pi-cluster/. If you need some configuration examples (executable on a Raspberry Pi Kubernetes Cluster) please check out my GitHub repository with configuration examples: https://github.com/MatthiasLohr/kubernetes-rpi-examples.
