Make IMAGE_REPO, IMAGE_NAME, IMAGE_TAG available in build.artifacts[i].docker.buildArgs

[javier-b-perez]

Expected behavior

apiVersion: skaffold/v2beta1
kind: Config
build:
  local:
    push: false
  artifacts:
  - image: gobuilder
    context: build/gobuilder
    docker:
      dockerfile: Dockerfile
  # These containers are using builders (like golang + tools) + src.
  - image: my-app
    docker:
      dockerfile: my-app/Dockerfile
      buildArgs:
        GOBUILDER: "{{.IMAGE_REPO}}/gobuilder:{{.IMAGE_TAG}}"

skaffold build --default-repo=gcr.io/my-project -t demo

Actual behavior

- my-app: Error checking cache.
getting hash for artifact "my-app": getting dependencies for "my-app": parsing ONBUILD instructions: retrieving image "<no value>/gobuilder:<no value>": parsing reference [<no value>/gobuilder:<no value>]: could not parse reference: <no value>/gobuilder:<no value>

Information

• Skaffold version: v1.10.1

Steps to reproduce the behavior

1. git clone https://github.com/javier-b-perez/skaffold-tags-demo.git
2. skaffold build --default-repo=gcr.io/my-project -t demo

Workaround

1. Update skaffold.yaml

apiVersion: skaffold/v2beta1
kind: Config
build:
  local:
    push: false
  artifacts:
  - image: basebuilder
    docker:
      dockerfile: Dockerfile.base
  # These containers are using builders (like golang + tools) + src.
  - image: my-app
    docker:
      dockerfile: Dockerfile
      buildArgs:
        BASEBUILDER: "gcr.io/my-project/basebuilder:demo"

2. Build builder

skaffold build --default-repo=gcr.io/my-project -t demo -b basebuilder

3. Build app

skaffold build --default-repo=gcr.io/my-project

@javier-b-perez Unfortunately the pr #3974 linked in #3229 only added the IMAGE_REPO, IMAGE_NAME and IMAGE_TAG to kaniko builder.

We need to do similar thing for docker builder here
