Deploy a Go app to Kubernetes by building a Docker image, pushing it to a registry, and applying a deployment manifest with kubectl.
Deploy a Go application to Kubernetes by building a container image, pushing it to a registry, and applying a Deployment manifest.
- Build the binary and create a Docker image using
docker build -t my-go-app:latest ..
- Push the image to a container registry with
docker push my-go-app:latest.
- Create a
deployment.yaml file defining the container image and replicas.
- Apply the configuration to your cluster using
kubectl apply -f deployment.yaml.
Deploying a Go application to Kubernetes packages your code into a portable container and tells the cluster how to run it. It is like shipping a pre-configured appliance to a data center and handing the manager a list of how many to install. You use this whenever you need your application to run reliably across multiple servers.
