Is it possible to see the dockerfile jib creates behind the scenes ? If yes then where and how can i locate it ?
Context - I am bit familiar with docker file and want to make sure the docker file that gets generated has everything required for my app to run successfully.
Jib does not generate Dockerfile or make any use of Docker during image building. You don't need to install Docker to use Jib.
For a normal project, if a Dockefile existed, some part of it would roughly look like this. However, do note that the Dockerfile in the link is mostly for informational purposes; almost all the time, there cannot be a Dockerfile that can accurately reproduce the image generated by Jib.
Related, note that the way Jib works is fundamentally different than Docker's:
the way Jib builds an image is fundamentally different from how the Docker CLI builds an image using
Dockerfile(reproducible vs. non-reproducible, declarative vs. imperative, Docker and Dockerfile-less build vs. requiring Docker daemon and client, requiring root-privilege vs. not). Jib is in a very different realm ...
UPDATE: if you want to examine the built image, check out dive.
