This build process assumes that you have already built the application using gradlew as specified in the parent README. If you haven't, this build will error out complaining of missing files.
Decide where you would like the built container to be stored. The default is quay.io/coffeepac/kafak-monitor. You can probably not write to this location so you should specifiy a new location either at the command line or in an environment variable
Using default tag/repo location
make container
Using command line flags
make container -e TAG=0.2
Using environment variables
export PREFIX=quay.io/your_userid/kafka-monitor
make container
make push
