Today I am working on fokais.com, trying to get to a point where I can launch
by workig through stripe integrations. This is my first time using stripe, so
there has been quite a bit to learn, and I am probably building in more than I
need to before launching, but I am learning, and not in a rush to launch.
I am building the fokais backent in python primarilyt with fastapi [1] and sqlmodel
on sqlite. My billing integration is going to be all Stripe.
Stripe Subscription Cancellations Docs # [2]
Here is a link to the stripe docs for your refrence, especially if you want to
see how to cancel subscriptions in other languages. They include code samples
for many popular languages.

User Model # [4]
This is the part of the user model that includes the cancel and reactivate
methods. It pretty much follows the stripe guide.

You can find your customers next billing date through the stripe api by using Invoice. and passing in customer, customer_details, subscription, or schedule.
import stripe
stripe.api_key = "sk_test_51ODvHtB26msLKqCAPBAo1qkBBuIfT5tQBX6YFWCLMsPixIExxITCRVa9tNCIqkdQS8olhR79NYXsFWBPKsM3LbGO00zEcNQfNI"
invoice = stripe.Invoice.upcoming(customer="cus_NeZwdNtLEOXuvB")
Within the invoice, you can find the next_payment_attempt as a epoch.
date = datetime.fromtimestamp(invoice.next_payment_attempt)
amount = invoice.amount_due
currency = invoice.currency

Search
Use the search APIs to look up and retrieve objects in your Stripe data. Using search is a faster alternative to paginating through all resources.
stripe.com [1]
Stripe has it’s own query language for querying data. I’m just getting into using it and it seems pretty good so far. I needed to lookup the price for products. I was able to find prices for my product using the python api as shown below.
stripe.Price.search(query="active: 'true' and product: 'prod_P8SfwtxJ45cWE2'")

Looking for a Heroku replacement, What I found was shocking!
Your browser does not support the audio element.
I’ve long hosted my personal blog as a static site on waylonwalker.com. It’s
all markdown, converted to html [1], and shipped as is. It’s been great, I’ve
moved it from GitHub Pages, to Netlify, tried Vercel for a minute, and have
landed on Cloudflare Pages. Each migration has not really been that
hard, it’s just pointing ci to a different host after the site has built.

Now the part that I have struggled with is how to cheaply host a server

I never really deployed anything that useful on heroku, but it seems like the

Dang this is such a good message. I can’t exactly relate to being forced into the overworking situation that PirateSofware is talking about. I can relate to being conditioned to feeling a certain way and changing that is very difficult. I can also relate to not feeling like I am getting enough done in the day. Sometimes a bit of separation is good.

page-break-after CSS property - CSS | MDN
The page-break-after CSS property adjusts page breaks after the current element.
MDN Web Docs · developer.mozilla.org [1]
I’m working on something that might go to print, so I want the page breaks to happen somewhat in my control as the content author. As I do my writing I break my content up in to many short sections using h2, sometimes an h3. These are generally short sections that go together, should stay together, and typically are not too lengthy to cause a large white space in print.
I found a way in css to only allow page breaks to happen on h2 and h3, and it turned out perfect, suck it WSIWIG editors

How to Build a Website or App - Syntax #696
This podcast episode covers a wide range of topics related to building a website or web application from start to finish.
syntax.fm [1]
Great tips in this one. They discuss everything from front end to backend, databases and ORMS, here are a few of my favorite points.
- Use good data or good fake data
- make it have some variation like long and short text
- Don’t use a database if you need one, static content is eaiser to manage
- end to end test, (does the site load page x)
- You DONT NEED all this complexity, you can deploy a site with HTML [2] and CSS.

Nice take by @t3dotgg [1]. Some of the old patterns that go deep into webdev, MVC, separation of concerns, REST, are things we are told to believe on day one, thrown so many things, no mental bandwidth, or experience to form our own opinions we must take them as fact. Rarely do we take these facts and revisit them with our new understandings years later.

GitHub - johanhaleby/kubetail: Bash script to tail Kubernetes logs from multiple pods at the same time
Bash script to tail Kubernetes logs from multiple pods at the same time - johanhaleby/kubetail
GitHub · github.com [1]
Kubetail is a pretty sick bash script that allows you to tail logs for multiple pods in one stream. Very handy when you have more than one replica running.
wget https://raw.githubusercontent.com/johanhaleby/kubetail/master/kubetail
chmod u+x ./kubetail
Now with kubetail I can tail all the logs for every shot-wayl-one pod in the shot namespace.

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.
kubectl create secret generic minio-access-key --from-literal=ACCESS_KEY=7FkTV**** -n shot
If you don’t use the --from-literal you will have to base64 encode it.
echo "7FkTV****" | openssl base64
Once you have your secret deployed, you have to update the container spec in your deployment manifest to get the valueFrom secretKeyRef.
spec:
containers:
- env:
- name: ACCESS_KEY
valueFrom:
secretKeyRef:
key: ACCESS_KEY
name: minio-access-key
- name: SECRET_KEY
valueFrom:
secretKeyRef:
key: SECRET_KEY
name: minio-secret-key
image: registry.wayl.one/shot-scraper-api
name: shot-wayl-one
ports:
- containerPort: 5000

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 [2].

I was looking to add running kubernetes jobs to a python cli I am creating, and I found this solution, mostly thanks to ollama run mistral:7b-instruct-q4_K_M 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.

# Load the default kubeconfig
config.load_kube_config()

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

In order to use k8s secrets manifest you first need to encode the data values.
echo -n 'mega_secret_key' | openssl base64

Can I access k3s using just kubectl (no sudo and no k3s command)

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

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
