Flash OpenWRT to NanoPi R6S eMMC and Expand Filesystem

Sat, 31 May 2025 15:30:00 +0100

Got a NanoPi R6S with FriendlyWRT and want OpenWRT on the eMMC? The OpenWRT sysupgrade images work but only use ~120MB of your 32GB eMMC. Here’s how to get the full space.

Open WebUI with Podman on macOS

Mon, 24 Mar 2025 12:34:54 +0100

If you lookup Open WebUI¹ and Ollama² on the internet, you’ll probably get examples that are all using Docker. What about Podman? Well, here you go!

Installation

We’re using homebrew, of course.

brew install ollama
brew install podman-desktop

I’ll not go into the details of setting up Podman Desktop³ and Ollama here because they both have pretty good online documention available (see resources at the bottom).

Configuration details

Ollama

By default, ollama will be listening on localhost:11434 - Make sure you start it before running the container, although, Open WebUI should pick it up afterwards anyway.

Switch to Podman Quadlets

If you wanted to run podman containers as a systemd service in the past, podman-generate-systemd was the way to go. Now in 2025, their Docs¹ say this:

DEPRECATED: Note: podman generate systemd is deprecated. We recommend using Quadlet files when running Podman containers or pods under systemd. There are no plans to remove the command. It will receive urgent bug fixes but no new features.

Let’s see, how that works and convert a simple podman container to a quadlet.
