Migrate to dockerfile-maven or Google Jib

[arey]

Spotify recommand recommend that new projects use dockerfile-maven instead of the old github.com/spotify/docker-maven-plugin.
We could also migrate to Google Jib: https://github.com/GoogleContainerTools/jib

I've tried to migrate to Google Jib with the jib-maven-plugin but I'm not satisfied with it: the is no version of Dockerize for the gcr.io/distroless/java image and the wait-for-it.sh script is not working. Thus I have to use the openjdk:8 Docker image.

You could check my commit: arey@1da92dd

Hey @arey, I checked out your commit on Windows 10 and the docker containers failed to start up due to this error: /usr/bin/env: ‘bash\r’: No such file or directory.
Since git checks out files with the default line endings of the OS on Windows it defaults to CRLF. I was able to use the dos2unix command to convert to unix line endings. after that the wait-for-it.sh worked as expected.

I have an interest in getting this merged into master, is there anything I can do to help?

Hi @damc-dev I've added a .gitattributesfile to my feature/jibbranch: https://github.com/arey/spring-petclinic-microservices/blob/feature/jib/.gitattributes
It should solve your issue without having to use dos2unix tool.

It could be great to use dockerize instead of wait-for-it.sh. Microservices startup appears be more stable with it.

Spring Boot layered jars is preferred to Google Jib: #155
