Kubernetes manifests can seem quite daunting at first, but it is important to understand that their apparent complexity is simply a result of the large number of customization options. In the end, manifests are used to deploy resources that interact with each other, which, among others, lead to the correct operations of containerized applications. Consequently, resources specified in a manifest must be configured accordingly. This article aims at explaining how manifests are structured to do so.

Kubernetes is a container orchestration system. As such, it features functions that are similar to that of Docker. If a container can be run with the Docker CLI, it can also be run equivalently using Kubernetes. This articles highlights such equivalence by presenting how to deploy a PostgreSQL instance using both technologies.

ChartMuseum is an open-source Helm chart repository server which can be used as a self-hosted alternative to Artifact Hub. Although it originally consists of only a server-side application to be interacted with via a REST API, its official UI, ChartMuseumUI, can be deployed to interact with ChartMuseum graphically. Unfortunately, ChartMuseumUI seems to be broken and the GitHub repository has been inactive for years now. Thus, I decided to make my own GUI for ChartMuseum.

Maintaining good habits can sometimes be hard. Recently, I've been looking at the way contributions are displayed on GitHub: a grid with a cell for each day, turning green if contributions have been made on that date. I realized that it motivated me to write code everyday, just to keep that grid as green as possible. So, I decided to create an app that provides a similar kind of motivation but for habits other than coding daily.

I live by myself far away from my relatives, which can can make them worried if they don't hear about me for too long. To reassure them, I made a simple web application which displays my recent activity alongside a list of emergency contacts.

URL query parameters are a convenient way to store the state of a view so that the user can return to it using the back button after navigating away. This short article introduces a method to add parameters to the current URL.

I recently replaced the RFID ring reader that I use to unlock my front door with an IoT fingerprint reader. An obvious advantage is that I risk losing my finger way less than a ring.

With newer versions of Microk8s, its GitLab integration changes slightly. Here are the key differences

Kong is a popular API gateway that can be used as a reverse proxy for clients to access back-end services. It can be run as a Docker container and, as such, can be deployed to Kubernetes. However, when doing so, requests might be severely impacted by unusually high latency. This can be solved by configuring the order in which Kong resolves DNS records.
