Deploy Go to Kubernetes

Deploy your Go application to Kubernetes by building a Docker image, pushing it to a registry, and applying a Deployment manifest.

1. Build the Docker image using your Go binary and push it to your container registry.

docker build -t your-registry/your-app:latest .
docker push your-registry/your-app:latest

2. Create a deployment.yaml file defining the container image and resource limits.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: go-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: go-app
  template:
    metadata:
      labels:
        app: go-app
    spec:
      containers:
      - name: go-app
        image: your-registry/your-app:latest
        ports:
        - containerPort: 8080

3. Apply the manifest to your cluster to start the application.

kubectl apply -f deployment.yaml

4. Verify the deployment is running and healthy.

kubectl get pods -l app=go-app

Deploying Go to Kubernetes packages your code into a portable container and instructs the cluster how to run it. Think of it like shipping a pre-built appliance to a warehouse that automatically manages its power and placement. You use this whenever you need your application to run reliably on a cluster of servers.
