Dockerfile multi stage support

[anonymouse-jj]

I often have different stages in a single Dockerfile and I'd like the option to specify the target in .gitpod.yml

Example .gitpod.yml:

image:
  file: .gitpod.Dockerfile
  #  target: devstage

Hi @anonymouse-jj! Thanks for the suggestion. Unfortunately, we won't be able to prioritize this at this time, given other competing priorities

This feature would be very useful and does not seem to require a significant implementation effort. Could you reconsider integrating the target stage?
