Today I needed access to an environment variable whilst building a Docker image from a Dockerfile. To make the example concrete, I wanted to get access to the Git commit hash exposed in a CircleCI build. The idea was to then use this commit hash inside my build as a cache buster on client side … Read more
Last night I clicked the update button when prompted to switch from Ubuntu 22.04 Jammy (I think!) to Ubuntu 23.04 Lunar. I say I think because I’m not entirely sure what version I was on before. Possibly I’d updated to 22.10… but it doesn’t matter. The fun comes in when I hit that update, but … Read more
Today I needed to resize a ton of stock photos in various sizes so that the result was each image was at most 800 pixels in width, but I wanted to maintain the aspect ratio. What I mean is that if the original image was 8256 x 5504 pixels (where that is width x height), … Read more
For reasons that currently escape me, I started using Docker for smbd a while back. I’m not sure if it’s the case by default, but my installation of Ubuntu has samba running as soon as the machine starts up. This conflicts with the Docker container implementation, and as the local samba starts before Docker, that … Read more
This morning I needed to do a deploy to production on a Kubernetes cluster. One of the useful commands is seeing the output of a kubectl get pods -n {some namespace}, which is one way to get a summary of the pods being transitioned between old and new. The “problem”, as such, is that the … Read more
A good few years back now I made a post on the previous iteration of this site about my problems with Portrait mode in Ubuntu. I still run a similar set of screens, but my triple monitor setup has slightly changed since then. What I will say is that in Ubuntu 22.x onwards (currently just … Read more
This is for my future reference, covering how do I connect a running container in a Kubernetes pod? First, it’s pretty useful to see all the pods in the namespace. Typically someone will have told me the right namespace to use, but if not, I can run: Which gives output like this: As with anything … Read more
Five days a week I ride my bike. A lot of those days are done indoors, on what is a very nerdy exercise bike setup. There’s a bit more too it than that, and if you are at all interested, have a read of (one of) my other blog(s) over at CyclingIndoors.co.uk. Why that’s relevant … Read more
To upgrade from Ubuntu 16.04 LTS to the latest LTS (Long Term Support) release, you’ll need to follow a series of steps. The current Ubuntu LTS at the time of writing is 22.04.3, and this process is unlikely to change in the near term future. Here are the steps I followed to upgrade from Ubuntu … Read more
My computer is dual use. Gaming, and work. It runs pretty much 24/7/365, but when I play a game at night in Windows, then reboot back into Linux, I have to manually log in and mount my drive(s) or my overnight backups don’t work. Of course, I frequently forget to log in. And even when … Read more
