Github：在具有多个 Dockerfile 的存储库中构建 docker 映像

Question

I have a repository that has multiple directories each containing a python script, a requirements.txt, and a Dockerfile. I want to use Github actions to build an image on merge to the main branch and push this image to Github packages. Each Dockerfile defines a running environment for the accompanying python script. But want to build only that directory's Dockerfile on which changes are made and tag each image with the directory name and a version number that is different from other directories version changes. How can I accomplish this? An example workflow.yml file would be awesome.

Answer 1

Yes, it is possible.

In order to trigger a separate build for every Dockerfile, you will need a separate workflow - eg for every Dockerfile - one workflow. The workflows should be triggered on push to main and specify paths for the Dockerfile.

For building the images themselves you can use GitHub Action Build and push Docker images
