Research direction

Start with the linked .github/workflows/bake.yml lines 226-228 to understand the single-target limitation, then review the linked bake-action subaction/matrix example. Document why Bake is limited to one target and explain how users can use a matrix strategy to handle multiple targets.

Written by the indexing model from the issue text.

Description

kind/docs

We currently limit Bake build to a single target: https://github.com/docker/github-builder-experimental/blob/e875129c872af249a9411fc0b1b1d1fe79ee6ddf/.github/workflows/bake.yml#L226-L228

Mainly because we don't have a way to discern which generated tags are associated to a target but also because a target could output build result locally while another one would push to registry.

We should document this but also explain how users can use a matrix strategy to solve this issue. For example using our matrix subaction: https://github.com/docker/bake-action/tree/master/subaction/matrix
