🚀 | Enable Multi-Architecture Docker Image Publishing (amd64 + arm64) #301

Description

@KarimGl

Which part of our software stack is concerned by the feature ?

Chutney

Describe your use case

Currently, the chutney-server and chutney-demo Docker images published to GHCR are built only for the default GitHub Actions runner architecture (linux/amd64).

As a result, users running on ARM platforms (e.g., Apple Silicon, ARM-based servers) encounter the following error when pulling the image:
no matching manifest for linux/arm64/v8 in the manifest list entries

Is your feature request related to a problem ?

No response

Describe the solution you'd like

To improve compatibility, we should publish multi-architecture Docker images (manifest lists) so that a single tag automatically works for both:

  • linux/amd64
  • linux/arm64

This will allow users to pull the image without specifying --platform.
