I’ve been looking for some ci/cd that I can host myself, but everything looks pretty big, so for now I am going to use just as my task runner. I installed with installer. curl https://i.wayl.one/casey/just | bash I set up my devtainer builds with just.

[1] I was curious to see what was going on inside of my minio object storage. Great technique here by Frank to create an inspector pod, then you can do as you wish with the data. I created the manifest as pvc-inspector.yml apiVersion: v1 kind: Pod metadata: name: pvc-inspector spec: containers: - image: busybox name: pvc-inspector command: ["tail"] args: ["-f", "/dev/null"] volumeMounts: - mountPath: /pvc name: pvc-mount volumes: - name: pvc-mount persistentVolumeClaim: claimName: pvc-name Then used it like this. # create pvc-inspector pod kubectl apply -f pvc-inspector.yml # exec into inspector kubectl exec -it pvc-inspector -- sh # explore data ls /pvc # cleanup kubectl delete -f pvc-inspector.yml Note This post is a thought [2].

Can I access k3s using just kubectl (no sudo and no k3s command) Can I access k3s using just kubectl (no sudo and no k3s command) Reddit · reddit.com [1] Right after installing k3s you are going to need to use sudo to use any kubectl command. The reason for this is that the default config is owned by root. To get around this you will need to make your own config and set the KUBECONFIG environment variable To do this I used sudo one last time to copy the k3s.yaml file into my own directory and take ownership of it. sudo cp /etc/rancher/k3s/k3s.yaml /home/waylon/.config/kube sudo chown -R waylon:waylon ~/.config/kube export KUBECONFIG=~/.config/kube/k3s.yaml Note This post is a thought [2].

Quick-Start Guide | K3s This guide will help you quickly launch a cluster with default options. Make sure your nodes meet the requirements before proceeding. docs.k3s.io [1] I recently spun up k3s in my homelab [2]. I’m trying to offload some work off of my free tier fly.io app in order to keep it free tier without crashing. # install and start k3s curl -sfL https://get.k3s.io | sh - # check to see if your nodes are started sudo kubectl get nodes My main hiccup so far was the machine I am running on runs zfs on root, and it would not start the master node. Rather than figuring out how to make zfs play nice I just pointed k3s to a drive that is not zfs. # manuallly sudo k3s server -d /mnt/vault/.rancher/k3s # without editing systemd service sudo ln -s /mnt/vault/.rancher/k3s /var/lib/rancher/k3s Note This post is a thought [3].

Litestar: Effortlessly Build Performant APIs We all know about Flask and Django. And of course FastAPI made a huge splash when it came on the scene a few years ago. But new web frameworks are being created all the time. And they have these ea... talkpython.fm [1] Litestar is an interesting api framework similar to fastpi, that I am interested to check out to see if it fits into some project scope. It sounds like it comes with a lot more batteries included for things like auth, but does not have hard opinions like django. At this point I’m not jumping off of fastapi [2], but its something I want to try. Note This post is a thought [3].
