Kubernetes Blackjack

• Flask server with game logic
• Preact frontend

To run in Minikube:

1. Make sure minikube is running:

minikube status

2. In the k8s directory, create services/deployments:

kubectl apply -f .

3. Enable an ingress controller:

minikube addons enable ingress

4. Open a browser to the minikube IP address. You can find it by running:

minikube ip

To run in Docker:

1. yarn watch in frontend directory
2. docker-compose up --build in root
3. Open localhost in a browser

To run locally:

1. LOCAL=true python server.py in backend directory
2. yarn watch in frontend directory
3. open dist/index.html in frontend directory

Making changes

If you make changes to a project, you'll need to do a few things to update kubernetes. For example, after making changes to frontend:

1. In the frontend directory, rebuild from src: yarn build:minikube
2. Rebuild docker image: docker build -t helloitsjoe/blackjack-preact-frontend:minikube . (Note the .)
3. Push to docker hub: docker push helloitsjoe/blackjack-preact-frontend:minikube
4. Despite the imagePullPolicy: Always in the deployment.yml, it will not pull a new image without restarting (apply is not enough)
5. In the k8s directory, bring down the running kubernetes pods for the frontend: kubectl delete -f preact-frontend.yml
6. Restart them: kubectl apply -f preact-frontend.yml
