Build the new Docker image. Check for previous version numbers on Docker Hub here.
docker build -t bufferapp/buffer-code-exercise-api:<YOUR-NEW-VERSION> .
Verify the Docker image runs correctly:
docker run --rm -p 8888:8888 bufferapp/buffer-code-exercise-api:<YOUR-NEW-VERSION>
curl http://localhost:8888
{
"status": "awesome"
}
Push the image to Docker hub
docker push buffer-code-exercise-api:<YOUR-NEW-VERSION>
Update the kubernetes.yaml file with your new image version and apply the changes (create if the service has been previously deleted).
kubectl apply -f kubernetes-deployment.yaml
Monitor your rollout:
kubectl -n internal get pods -l app=buffer-code-exercise-api
If a change is required to the Kubernetes service, first get the AWS SSL cert ARN from the AWS dashboard, then apply the changes:
kubectl apply -f kubernetes-service.yaml
