Docker DAB support does not currently work (still in experimental)

[cdrage]

Converting the current example we have produces this error:

▶ ./kompose convert -f examples/docker-compose-bundle.dab
ERRO Could not parse config for project examples : yaml: unmarshal errors:
  line 24: cannot unmarshal !!str `0.1` into config.RawService 
FATA Failed to load compose file: yaml: unmarshal errors:
  line 24: cannot unmarshal !!str `0.1` into config.RawService

@ngtuna Any idea why this may be happening? I'm assuming problems with floating values not being converted.

I am proposing a GSoC project to improve the dab support:

@sebgoa Should we deprecate this feature since it's still experimental within Docker and at the moment doesn't work with Kompose?

[sebgoa]

if it does not work, it is a regression that we should fix.

Is DAB actually used somewhere? Do we know if someone is using dab even with docker?

[sebgoa]

Honestly I have not kept up with the dab development. but I will check.

Please, I am interested in working on this project for the Google Summer of Code. I am very comfortable working with programming languages like Java, C/C++, Python and Go. I am very passionate about cloud and container technologies, and I would like to get some help that would enable me better familiarizing myself with the project. I am already familiar with Docker and Docker compose and I am currently familiarizing myself with Kubernetes.

I believe this link: moby/moby#26876 would be the best in terms of keeping track IF DAB comes out of being experimental.

It has happened in the past that an experimental feature wasn't accepted into Docker. So it'd be best to keep track of this while we continue to support development / improvements.

I'm closing this for now until Docker figures out DAB's role.
