Unable to use modules with common base image artifact dependencies

[viglesiasce]

Expected behavior

Use a single base image (as per this example) between two modules and have a requires between one module and the other.

In this case I have a frontend and backend that share mostly the same build environment so I have a base Dockerfile shared between them.

Actual behavior

skaffold build throws an error due to duplicate artifacts:

❯ skaffold build
invalid skaffold config: found duplicate images "base": artifact image names must be unique across all configurations

Information

• Skaffold version: v1.21.0
• Operating system: MacOS arm64
• Installed via: Cloud Code
• Contents of skaffold.yaml:

apiVersion: skaffold/v2beta13
kind: Config
metadata:
  name: frontend
requires:
  - path: ../backend
build:
  artifacts:
  - image: base
    context: ../../base
  - image: sample-app-frontend-dev
    requires:
      - alias: BASE
        image: base
deploy:
  kustomize:
    paths:
    - k8s/dev
profiles:
- name: prod
  deploy:
    kustomize:
      paths:
      - k8s/prod
---

    docker:
      dockerfile: Dockerfile

    - k8s/dev

how about:

apiVersion: skaffold/v2beta13
kind: Config
metadata:
  name: base
build:
  artifacts:
  - image: base
    context: ../../base
---
apiVersion: skaffold/v2beta13
kind: Config
metadata:
  name: frontend
requires:
  - configs: [base, backend]
build:
  artifacts:
  - image: sample-app-frontend-dev
    requires:
      - alias: BASE
        image: base
deploy:
  kustomize:
    paths:
    - k8s/dev
profiles:
- name: prod
  deploy:
    kustomize:
      paths:
      - k8s/prod
---
apiVersion: skaffold/v2beta13
kind: Config
metadata:
  name: backend
requires:
  - configs: [base]
build:
  artifacts:
  - image: sample-app-backend-dev
    docker:
      dockerfile: Dockerfile
    requires:
    - alias: BASE
      image: base
deploy:
  kustomize:
    paths:
    - k8s/dev
profiles:
- name: prod
  deploy:
    kustomize:
      paths:
      - k8s/prod

The issue you're facing is that the artifact image property needs to be unique across. Also to declare a reusable base artifact it needs to be a single artifact.

Got it! Tested this and it worked! I'm upstream my example so the end to end gets represented here.
