Cloud Native Java, 2020 Redux. This contains the code to the updated version of my talk "Cloud Native Java," as of Q4 2020.
- 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
