The same answer applies here as with your other question: https://news.ycombinator.com/item?id=16357653 but with some additions, you can use AWS lambda for that with some hacks or set up your own service, just spin up a docker image and run what you need doing in that (its what you do with pipelines either way). You can use githooks if you want functions to be executed at some self-hosted repository once someone pushes.
