Kubernetes Local Dev Environment

• Install Rancher Desktop
• Review simplest k8s deployment example
• Review Rancher Desktop Using the Traefik Ingress Controller
• Build the API docker image via npm run prod:api. It will utilize the production environment variables at apps/api/src/environments/environment.prod.ts and produce a Docker image tagged zen-api:latest
• Fill out JWT_PRIVATE_KEY & JWT_PUBLIC_KEY under deploy/dev/k8s-secrets.yaml. The other secrets can be left blank. Refer to deploy/NOTES.md for instructions of how to generate keys using openssl.
• Setup a minimal DNS utilizing nip.io
  • Get your ingress IP via kubectl get node/<MACHINE_NAME> -o json under status.addresses.address with "type": "InternalIP"
  • Edit the deploy/dev/k8s-setup.yaml manifest and replace <IP> with the IP looked up from the previous step

# Apply the manifests
kubectl apply -f deploy/dev/k8s-secrets.yaml
kubectl apply -f deploy/dev/k8s-postgres.yaml
kubectl apply -f deploy/dev/k8s-setup.yaml

# Expose PostgreSQL pod via port forward
kubectl get pods
kubectl port-forward <POSTGRES_POD> 5446:5432

# Set the port for the DATABASE_URL in the .env file to 5446
# Run Prisma Migrate
pnpm prisma migrate deploy --schema apps/api/prisma/schema.prisma

# Connect to the DB via psql to verify succesful DB deployment
psql -h localhost -U zenadmin -p 5446

Modify libs/common/src/lib/environment.ts to point to the local k8s deployment. Replace <IP> with your ingress IP

export class EnvironmentDev implements Environment {
  //...
  url = {
    loginRedirect: '/',
    api: 'http://zen.<IP>.nip.io',
    portal: 'http://localhost:4200/#',
    graphql: 'http://zen.<IP>.nip.io/graphql',
    graphqlSubscriptions: 'ws://zen.<IP>.nip.io/graphql',
  };
}

• Run npm start to start the Angular app to test the API running in k8s

• To build the static HTML/CSS assets for production, utilize the npm script npm run prod:portal
