I encountered persistent issues with my container image build pipeline. The pipeline is run by my local GitLab CI instance. After struggling for a considerable period, I decided to address the problem by transitioning from a build setup relying on “docker” to a new setup built on “podman/buildah”. This required a complete overhaul of the build process. Unfortunately, this change broke the deployment of my website using GitLab CI.
I ran a rather decent monitoring system for my servers at home based on prometheus. My monitoring service sends an alert, if some file systems start filling up. Unfortunately, in most cases, I don’t know, what file(s) cause this mess. I use ncdu to find the largest files in the alerted filesystem. This short article shows how to install and use this small helper.
Some time ago, I started to set up the “Network UPS Tools” (NUT) for my uninterruptible power supply (UPS) “Eaton 3S”. It’s a UPS which can be connected to a computer via USB cable.
I bought an “Eaton 3S” uninterruptible power supply (UPS) some time ago. It is supposed to support my servers with power in case of a power loss. I also wanted to get notified about those “power down” events, so I looked for an open-source software to monitor the UPS hardware. I found the “Network UPS Tools” (NUT). In this article, I describe some of the pitfalls I came across.
This blog post dives into setting up the Open Source “S3” compatible object storage server “MinIO” as backend for “restic” backups. The main focus of this setup is to have a stable storage backend with nearly zero maintenance – ok more or less zero maintenance.
One of “Go”’s strengths is its capability to build your “Go” project cross-platform for all kinds of operating systems and architectures, e. g. windows/amd64 (Windows), linux/386 (Linux), darwin/amd64 (MacOS). But setting up the environment for this is not that easy. This article is a small “HOWTO” listing all the steps required to set up a cross-platform “Go” environment.
Occasionally I get some really weird errors when I try to install gems using gem or bundler. It took me some time to find out the reason for this. Read on if you’d like to hear the full story.
