Local Kubernetes Setup

Docker

Local builds and testing uses docker to generate the container. It is recommended that Docker Desktop is used.

Minikube

Minikube is used for deploying the service to kubernetes locally.

• Install Minikube
• Start Minikube: minikube -p minikube start --driver=docker
• Create the metalus namespace once: kubectl create namespace metalus
• Set the default Namespace: kubectl config set-context --current --namespace=metalus

Build and Publish locally

• Make sure that containers are published to docker: eval $(minikube -p minikube docker-env)
• Build and publish locally: sbt clean docker:publishLocal

Deploy locally

• Run the build steps
• Deploy the container image to minikube: kubectl apply -f k8s/deploy-local.yml
• Setup Minikube Load Balancer (must be in a different terminal window than the minkube terminal): minikube tunnel
• Setup the Load Balancer: kubectl expose deployment process- --type=LoadBalancer --name=process-preview-services-lb --port=9000

Undeploy locally

Delete the local deployment: kubectl delete -f k8s/deploy-local.yml

Useful Kubernetes Commands

• Show Pods - kubectl get pods
• Show Logs - kubectl logs <container-name>
• Pod Shell Access - kubectl exec --stdin --tty <container-name> -- /bin/bash
