Research direction

Start with the devcontainers CLI path invoked by the devcontainers action when publishing all templates. Review the linked devcontainers/images build guidance and the manifest-list documentation, then determine how publishing should produce both aarch64 and amd64 images; done means the published templates expose both platforms in a multi-architecture manifest.

Written by the indexing model from the issue text.

Description

I use the devcontainers action which calls the devcontainers cli to publish all templates at once. I want to support multiple platforms (aarch64 and amd64).

I might follow https://github.com/devcontainers/images/tree/main/build#build-and-image-generation-for-devcontainers but it looks like a PITA

Some basic research

Create a Manifest List?
