docker v8 image not supported on Apple Silicon

Expected behavior:

Locally, I should be able to run a docker compose up with image: coralproject/talk:8 on an apple silicon laptop.

Actual behavior:

I get an error no matching manifest for linux/arm64/v8 in the manifest list entries

This is resolvable by adding platform: linux/amd64 to the docker-compose file, but is it possible that arm architecture could be added when pushing images to docker hub? Or does the stack actually need to run on amd64 and maybe docs should be updated with the platform line?

Here's the full working docker-compose file:

version: "2"
services:
  talk:
    # Added to avoid error about no matching manifest for linux/arm64/v8 in the manifest list entries
    platform: linux/amd64
    image: coralproject/talk:8.5.0
    ports:
      - "127.0.0.1:5000:5000"
    depends_on:
      - mongo
      - redis
    environment:
      - MONGODB_URI=mongodb://mongo:27017/coral
      - REDIS_URI=redis://redis:6379
      - SIGNING_SECRET=[redacted]
  mongo:
    image: mongo:4.2
    volumes:
      - ./data/mongo:/data/db
  redis:
    image: redis:3.2
    volumes:
      - ./data/redis:/data

Hello, thank you for reporting this issue. We have a PR open to add the platform line to docker-compose here: https://github.com/coralproject/talk/pull/4378. This will be included in an upcoming release.

We are also working toward adding arm architecture when pushing images. Here is a PR related to this work: https://github.com/coralproject/talk/pull/4386
