Upgrade notes

v1 to v2

  • Input path is now called context for consistency with other Docker build tools
  • path defaults to current git repository so checkout action is not required in a workflow
  • Rename dockerfile input to file for consistency with other Docker build tools
  • Rename always_pull input to pull for consistency with other Docker build tools
  • Add builder input to be able to choose a builder instance through our setup-buildx action
  • Add platforms input to support multi-platform builds
  • Add allow input
  • Add load input
  • Add outputs input
  • Add cache-from input (cache_froms removed)
  • Add cache-to input
  • Rename build_args input to build-args for consistency with other Docker build tools
  • Add secrets input
  • Review tags input
  • Remove repository input. See Simple workflow for migration
  • Remove username, password and registry inputs. Login support moved to docker/login-action repo
  • Remove tag_with_sha, tag_with_ref, add_git_labels inputs. See Tags with ref and Git labels for migration
  • Handle Git context
  • Add digest output
