Building Applications

SpringBoot

[[source,bash]

pack build example/helloboot \
   --builder quay.io/kameshsampath/java-11-jvm-builder:v1.0.0 \
   --path $PROJECT_HOME/apps/helloboot

Tip

If you have a maven repository manager , then you can run the builder with an environment variable MAVEN_MIRROR_URL as shown: pack build example/helloboot \ --env MAVEN_MIRROR_URL="<MAVEN_MIRROR_URL>" \ --builder quay.io/kameshsampath/java-11-jvm-builder:tip \ --path $PROJECT_HOME/apps/helloboot \ --verbose

To run and test the image:

[[source,bash]

docker run -it --rm -p 8080:8080 example/helloboot

Doing curl localhost:8080/hello should return an response Hello SpringBoot!
