A docker job scheduler (aka. crontab for docker)

In late 2025 the company behind MinIO decided to abandon it to pursue other commercial interests. As well as upsetting a bunch of folk, it also put the cat amongst the pigeons of many software demos that relied on MinIO to emulate S3 storage locally, not to mention build pipelines that used it for validating S3 compatibility. In this blog post I’m going to look at some alternatives to MinIO.

VPN client in a thin Docker container for multiple VPN providers, written in Go, and using OpenVPN or Wireguard, DNS over TLS, with a few proxy servers built-in.

TL;DR Umami analytics (built with Next.js) had an RCE vulnerability. Got exploited, installed cryptominers Mined Monero for 10 days at 1000%+ CPU Container isolation saved me because it ran as non-root with no mounts Fix: docker rm umami and enable firewall Lesson: Know what your dependencies are built with, and configure containers properly

Booting and auto provisioning a Docker Swarm cluster with PXE and enjoying zero-downtime deployments from a single git repository

Here’s the idea. I have a solo project that I’m working on, and instead of hacking away on the main branch, I’m using a full feature branch and pull request workflow to keep my changes organized. This might seem like overkill, but it’s helpful for me because I tend to bounce around and leave things half done. I can run things locally and test different things by switching between branches. But I’m also doing a lot more AI-assisted development. Locally I use Claude Code. But I’ve been experimenting with allowing Github Copilot to create PRs. I create a github issue, assign it to copilot, and it spins up in the cloud and does work. Afterwards it opens a pull request for me to review. So even though this is a “solo” project, I end up with pull requests that I didn’t write myself and I need to validate.

Until recently, I used to think that serving static websites from Docker would be a waste of bandwith and storage. Bundling nginx or various other heavy runtimes inside a Docker image for the sole purpose of serving static files didn’t seem like the best idea - Netlify or Github Pages can handle this much better. But my hobby server was sad and cried digital tears.

docker run -it --rm -p 3000:3000 my-static-website

A central Obsidian server, running in my homelab, accessible via browser, no desktop clients, no mobile apps, just one self-hosted solution available from anywhere I go.

In this tutorial, we will guide you through the process of installing Docker on your Android phone, specifically using a OnePlus 6T with postmarketOS. I also wrote another blog post explaining how you can run this phone without a battery, allowing it to run forever as long as it remains connected to a power source. If you’re interested, feel free to check it out! This guide can be adapted only for phones on the postmarketOS device list. Please note that this process will erase all data on your phone, so it’s important to use a device you don’t need.

Unprivileged LXC containers do not have access to the networking resource needed for Tailscale to work. This article explains how to give it access.

Creates an ssh+git user that creates repositories on the fly and lets you run scripts or hit HTTP endpoints when you push code. Build your own Heroku. Push code anywhere. It's just not a post-receive hook. It's a powerful wrapper around pre-receive giving you easy access to the code that was pushed while still being able to send output back to the git user.

Buildstep is the glue that turns Docker and gitreceive into a mini-Heroku

Docker is an open-source engine which automates the deployment of applications as highly portable, self-sufficient containers which are independent of hardware, language, framework, packaging system and hosting provider.
