a-dockerfile

Using the Dockerfile

Classic: build using maven, then package into an image

./mvnw package -DskipTests

docker build -f src/main/docker/Dockerfile -t myapp .

Multi stage build: 1 stage to build, other stage to package into an image

docker build -f src/main/docker/Dockerfile.multi -t myapp .

Run the container

docker run -p 8080:8080 -it myapp:latest
