Deploying custom-built deck using bom


I built custom deck image and deployed it as follows:

  • stored as public image in docker hub registry
  • created .hal/default/service-settings/deck.yml containing “artifactId: imageName”
  • executed “hal deploy apply --service-names deck”

I would prefer to define the custom bom, and point deck to image in private gcr.
Is it possible to do that?
What will be the format of the bom file?
