Kubernetes Deployment Guide for Dutchie Backend

Prerequisites

1. Access to your remote Kubernetes cluster
2. kubectl configured to connect to your cluster
3. Docker installed locally (to build the image)
4. Access to a Docker registry (Docker Hub, Google Container Registry, etc.)

Step-by-Step Deployment

1. Build and Push Docker Image

# Navigate to backend directory
cd /home/kelly/dutchie-menus/backend

# Build the Docker image
docker build -t your-registry/dutchie-backend:latest .

# Log in to your Docker registry (example for Docker Hub)
docker login

# Push the image
docker push your-registry/dutchie-backend:latest

2. Update Kubernetes Manifests

Edit the following files with your actual values:

k8s/secret.yaml - Add your database and service credentials k8s/deployment.yaml - Replace YOUR_REGISTRY/dutchie-backend:latest with your actual image name

3. Deploy to Kubernetes

# Connect to your remote cluster (method depends on your provider)
# Example for GKE:
# gcloud container clusters get-credentials YOUR_CLUSTER --region YOUR_REGION

# Example for AWS EKS:
# aws eks update-kubeconfig --name YOUR_CLUSTER --region YOUR_REGION

# Verify connection
kubectl cluster-info

# Apply the manifests
kubectl apply -f k8s/configmap.yaml
kubectl apply -f k8s/secret.yaml
kubectl apply -f k8s/deployment.yaml
kubectl apply -f k8s/service.yaml

# Check deployment status
kubectl get deployments
kubectl get pods
kubectl get services

4. Get Your Public IP

# Wait for LoadBalancer to provision (this may take 2-5 minutes)
kubectl get service dutchie-backend --watch

# Once EXTERNAL-IP shows an IP address (not <pending>), that's your public IP
kubectl get service dutchie-backend

The output will look like:

NAME              TYPE           CLUSTER-IP      EXTERNAL-IP       PORT(S)        AGE
dutchie-backend   LoadBalancer   10.0.45.123     203.0.113.45     80:30123/TCP   2m

Your API will be available at: http://203.0.113.45 (use your actual EXTERNAL-IP)

5. Update WordPress Plugin

Update the "Dutchie Menus Settings" in your WordPress site:

• API URL: http://YOUR_EXTERNAL_IP (or https://your-domain.com if you set up DNS)

6. Verify Deployment

# Check pod logs
kubectl logs -l app=dutchie-backend --tail=100

# Test the health endpoint
curl http://YOUR_EXTERNAL_IP/health

Updating the Deployment

When you make changes to your code:

# 1. Build new image with a tag
docker build -t your-registry/dutchie-backend:v1.1 .
docker push your-registry/dutchie-backend:v1.1

# 2. Update deployment
kubectl set image deployment/dutchie-backend backend=your-registry/dutchie-backend:v1.1

# 3. Check rollout status
kubectl rollout status deployment/dutchie-backend

Troubleshooting

# View pod logs
kubectl logs -l app=dutchie-backend --tail=100 --follow

# Describe pod (shows events and errors)
kubectl describe pod -l app=dutchie-backend

# Get into a pod shell
kubectl exec -it $(kubectl get pod -l app=dutchie-backend -o jsonpath='{.items[0].metadata.name}') -- sh

# Check service
kubectl describe service dutchie-backend

Setting up HTTPS (Optional but Recommended)

For production, you should use HTTPS. Options:

1. Ingress with cert-manager (recommended for most cases)
2. Cloud provider's load balancer with SSL certificate
3. Cloudflare in front of your LoadBalancer

Let me know if you need help setting up HTTPS!

Clean Up

To remove everything:

kubectl delete -f k8s/
