Bootiful Kubernetes

• Build a Spring Boot application that uses Packeto and Buildacks and publishes it to a registry
• Here's how you publish it to a registry like Google's Container Registry:

export APP_NAME=hello-java
export PROJECT_ID=bootiful

mvn -DskipTests=true clean spring-boot:build-image
image_id=$(docker images -q $APP_NAME)

docker tag "${image_id}" gcr.io/${PROJECT_ID}/${APP_NAME}
docker push gcr.io/${PROJECT_ID}/${APP_NAME}
docker pull gcr.io/${PROJECT_ID}/${APP_NAME}:latest

kubectl create deployment ${APP_NAME} --image=gcr.io/${PROJECT_ID}/${APP_NAME}
kubectl expose deployment ${APP_NAME} --port=80 --target-port=8080 --name=${APP_NAME} --type=LoadBalancer

kubectl describe services $APP_NAME
