Setting up Grafana on Raspberry Pi with Docker (compose)

2021-01-05 4 min read anoff

In previous blog posts I showed you how to setup a Raspberry Pi with docker-compose support and how to run InfluxDB on your Raspberry Pi. This tutorial will add Grafana to your Pi-stack and give you a complete monitoring setup. The InfluxDB+Grafana stack is heavily used in DevOps scenarios but also extremely useful if you want to visualize any kind of timeseries data at home; power consumption, smart home events, computer uptime, amount of devices in your network, weather in your basement … endless opportunities at your fingertips!

Running influxdb on Raspberry Pi using Docker compose

This blog post will explain how you can setup influxdb (and the telegraf plugin) on your Raspberry Pi using docker-compose. We will use the config-as-code to create a reproducible setup. This is extremely helpful for hobby projects that you come back to every now-and-then because you can lookup exactly what you are running 😉

How to setup Raspberry Pi as home server with Docker support

This blog post will cover how to setup a Raspberry Pi with Docker support. It will also cover some basic steps that will make it easier to work with your RasPi later on. This setup will work completely without monitor/keyboard for your Raspberry but you need a LAN connection to it. I wrote most commands so they are easily pastable and do not require too much interactive work - you should however carefully read what is going on with each of those commands before you fire them off!

Building autoscaling CI infrastructure with Azure Kubernetes

2019-10-17 9 min read anoff

Ever wanted to create a build agent factory where you do not have to care about how many build agents you need at a given point? With this post I want to share my experience setting up a dedicated CI runner infrastructure with the Azure + Pipelines ecosystem. The main features of the solution are automated scaling, ephemeral build agents, docker based environments, minimal operation responsible and strong pay-per-use billing concepts. Continue reading

Migrating to Azure Pipelines

2019-08-24 10 min read anoff

Beginning of the year I switched my blogs build chain from Travis CI to drone CI. Due to some tasks with Azure DevOps at work I wanted to test how good it fits my private projects. In this post I will NOT tell you how to set up your pipelines project because Microsoft has great docs for that. Instead this post will cover how to best put your build workflow into a pipeline specification. Continue reading

Continuous Vitae - Auto built and git versioned CV

2019-04-08 6 min read anoff

Versioning your CV is important. One traditional approach is to date it whenever you send it out. I chose to present my CV on my website and host it on GitHub. In this blog post I want to explain how I set up continuous integration pipeline for building my CV that automatically injects a unique version into each build. This method is applicable for anyone choosing to ascii-based CV - in my case LaTeX. Continue reading

Hosting Gitea and Drone with Docker

2019-03-24 8 min read anoff

This post will walk you through setting up a self hosted git based continuous integration environment on a two machine setup - assuming you already have two virtual machines at your disposal. Using Gitea for git hosting and contribution management and Drone for docker-based build jobs, this will guide you through creating docker-compose files as well as configuring the individual services and getting SSL certificates via traefik. Docker and docker-compose knowledge is required for this tutorial. It mostly focuses on the correct configuration of all the services at play here and not explaining their basic functionality.

This tutorial uses Azure resources so some of the aspects might not be 100% applicable if you chose another infrastructure provider.

Get Hugo to render (nice) Asciidocs

While migrating my blog from Jekyll to Hugo I went down quite a rabbit hole. While setup and migration to Hugo was a breeze, I spent a lot of time making my .adoc formatted post work with the new blog. After working through several GitHub issues I ended up manipulating the DOM with Javascript to get admonitions working. It still doesn’t feel right - but hey it works! 🤷‍♂️ This post will cover the steps I took in case I myself or anyone out there ever needs to do this again. Continue reading
