Multi-stage Docker Build for Java Applications

This repository shows how to create a multi-stage Docker build for Java application.

Single-stage

1. Build: docker image build -f Dockerfile.single -t people:singlestage .

2. Run: docker container run -it -p 8080:8080 people:singlestage

3. Access: curl http://localhost:8080/people/resources/persons

Multi-stage

1. Build: docker image build -f Dockerfile -t people:multistage .

2. Run: docker container run -it -p 8080:8080 people:multistage

3. Access: curl http://localhost:8080/people/resources/persons

docker-java-multistage's Issues

Mounting local Maven Repo

First thanks for this example.
I was just wondering whether you see a possibility to specify an existing local Maven repository which could be used for the build. This way not all artifacts have to be downloaded every time during a build (considering one would have a application with more dependencies).
Thanks,
Thorsten

"maven:3.5-jdk-8 as BUILD" is not a valid repository/tag

I ran:

docker image build -f Dockerfile -t people:multistage .

and got:
Sending build context to Docker daemon 164.9 kB
Step 1/6 : FROM maven:3.5-jdk-8 as BUILD
Error parsing reference: "maven:3.5-jdk-8 as BUILD" is not a valid repository/tag: invalid reference format

Here is my docker version:

docker --version

Docker version 17.03.1-ce, build c6d412e
