Reddit - Please wait for verification 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 References: [1]: https://www.reddit.com/r/kubernetes/comments/cojjf5/can_i_access_k3s_using_just_kubectl_no_sudo_and/

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 References: [1]: https://docs.k3s.io/quick-start [2]: /homelab/

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. References: [1]: https://talkpython.fm/episodes/show/433/litestar-effortlessly-build-performant-apis [2]: /fastapi/

GitHub - florimondmanca/arel: Lightweight browser hot reload for Python ASGI web apps Lightweight browser hot reload for Python ASGI web apps - florimondmanca/arel GitHub · github.com [1] arel is a “Lightweight browser hot reload for Python ASGI web apps” I just implemented this on my thoughts website using fastapi [2], and it’s incredibly fast and lightweight. There just two lines of js that make a web socket connection back to the backend that watches for changes.
