I am converting my docker compose env secrets over to k8s secrets. This guide was clear and to the point how I can replicate this exact workflow. First set the secret, the easiest way is to use kubectl wtih –from-literal because it automatically base64 encodes for you. If you don’t use the you will have to base64 encode it. Once you have your secret deployed, you have to update the container spec in your deployment manifest to get the valueFrom secretKeyRef.

waylon walker (@_WaylonWalker) on X Which is more complicated X (formerly Twitter) · twitter.com Wow, shocked at these results. All this time I’ve been told and believed that k8s is incredibly hard, and you need a $1M problem before you think about it because it will take a $1M team to maintain it. So far my experience has been good, and I definitely do not have a $1M problem in my homelab.

External Link thoughts.waylonwalker.com I was looking to add running kubernetes jobs to a python cli I am creating, and I found this solution, mostly thanks to and my loose understanding of what the yaml syntax is supposed to look like for a kubernetes job. This will let me create a job in the cluster, choose the image that runs, the command that is called, and how long until the job expires and is cleaned up. While the job still exists I can go in and look at the logs, but once its ttl has expired they are gone.

Reddit reddit.com Right after installing k3s you are going to need to use to use any command. The reason for this is that the default config is owned by root.

Pagefind Pagefind is a fully static search library that aims to perform well on large sites, while using as little of your users’ bandwidth as possible, and without hosting any infrastructure. Pagefind · pagefind.app Pagefind is absolutely insane. I’ve tried a number of static site searches, and found them all hard to get get going, clunky and not the best experience as a user or developer. I setup pagefind in about 2 minutes on my site where it found and indexed 833 pages in 2 minutes. The only downside I see so far is that it is a lot of bandwidth to the user. On simulated slow 3G you can definitly feel it, but not terrible. Anything slower and its going to start feeling frustrating. edit: I have actually fully deployed it on waylonwalker.com, and its fast! create the index Then I put this on a page, it looks really nice on a white background, but would need some work to drop into a dark theme.
