Running your own docker registry in one line

Example of how to add a pvc to a deployment.

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.

In order to use k8s secrets manifest you first need to encode the data values.

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.

I recently spun up k3s in my homelab. 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.

Tailwind comes with space that I have never heard of that is made to give margin and padding together in one class. Adam dropped it here in the Tailwind Connect conference.

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, but its something I want to try.

Deleting a fly postgres db cluster was not straightforward to me as the app name is not inferred from the toml like it is for the main app.

![[None]]

Yet again twitter cards were causing me pain. This time it was me not realizing that they require full urls, and not relative or abolute urls.

This was not working

<meta name="twitter:image" content="/shot/?path={{ request.url|quote_plus }}" content-type='image/png'/>

This does work with a full url

Boot.dev is crushing it with these interviews. This one has Wes Bos, includes teaching, webdev, where is webdev headed.

This seems like a promising tool to use with ollama.

ollama is the easiest to get going local llm tool that I have tried, and seems to be crazy fast. It feels faster than chat gpt, which has not been the experience I have had previously with running llm’s on my hardware.

sse-FastAPI.">starlette provides server sent events for startlette and FastApi. I’m evaluating for use with htmx.

Controlling overflow with tailwindcss

Default scrollbars on a dark theme website are just the ugliest thing. This page covers all the pseudo selectors needed to style the scrollbar.

Wincent (Greg Hurrel) has a pretty solid and fast zshrc. I recently grabbed his completion section and it seems to be working better than whatever I had.

zsh completion snippet

All the hover, select, autofil, focus combinations have left me confused on how to consistently get my form elements styled in dark mode

This snippet from CSS tricks has fixed all the different states for me to give me full control.

arel is a “Lightweight browser hot reload for Python ASGI web apps”

I just implemented this on my thoughts website using fastapi, 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.

When in development mode, this snippet gets injected directly on the page and does a refresh when arel detects a change.

import os import arel from fastapi import FastAPI, Request from fastapi.templating import Jinja2Templates app = FastAPI() templates = Jinja2Templates("templates") if _debug := os.getenv("DEBUG"): hot_reload = arel.HotReload(paths=[arel.Path(".")]) app.add_websocket_route("/hot-reload", route=hot_reload, name="hot-reload") app.add_event_handler("startup", hot_reload.startup) app.add_event_handler("shutdown", hot_reload.shutdown) templates.env.globals["DEBUG"] = _debug templates.env.globals["hot_reload"] = hot_reload @app.get("/") def index(request: Request): return templates.TemplateResponse("index.html", context={"request": request}) # run: # DEBUG=true uvicorn main:app --reload

I just discovered arel for hot reloading python applications when content changes from this snippet that implements it for fatapi.
