The GitHub runner windows-2019 has Docker installed, so you can build and push images with a workflow like this:

Would be great if this action supported Windows image builds on Windows runners.

Hi @sixeyed , thanks for your feedback. This is interesting and I can see it being useful. Currently the action runs using a Linux container hence it wouldn't work with the Windows hosts so this will need some investigating on the best way to support this. I will discuss this with our PM and see if we can get it prioritized

FYI this is working with Windows https://github.com/mr-smithers-excellent/docker-build-push but hitting some issues on second push.

We have Linux images and Windows based images (for On prem customers).

Windows containers require a special treatment due to buildx not being compatible, yet.

## Description Docker builds and smoke tests are only run on Linux machines as building docker containers on macOS and windows runners introduces complexity to the CI setup that we consider not worth the effort: - macOS runners require the setup of [colima as a docker runtime]( actions/runner-images#6216 ) which adds another 1.5-2m to the runtime - on macOS testcontainers failed to detect the docker environment unless [additional environment variables]( https://www.testcontainers.org/features/configuration/#customizing-docker-host-detection ) have been set - some docker related actions are not supported on windows runners like [`docker/build-push-action`]( docker/build-push-action#18 (comment) ) - the docker setup on Githubs windows runners seems to be bound to the `windows/amd64` platform, see e.g. this [log]( https://github.com/camunda/zeebe/actions/runs/3500015748/jobs/5862231609 ) Usage of native arm64 runners is listed as a separate sub-task on #10986 . ## Related issues closes #11020 Co-authored-by: Meggle (Sebastian Bathke) <[email protected]> Co-authored-by: Sebastian Bathke (Meggle) <[email protected]>
