Share built image between jobs with GitHub Actions	ci, github actions, gha, buildkit, buildx

As each job is isolated in its own runner, you can't use your built image between jobs, except if you're using self-hosted runners{:target="blank" rel="noopener" class=""} However, you can pass data between jobs{:target="blank" rel="noopener" class=""} in a workflow using the actions/upload-artifact{:target="blank" rel="noopener" class=""} and actions/download-artifact{:target="blank" rel="noopener" class=""} actions:
