Alpine image for arm64

[jlamande]

This is a feature request.

Our Kubernetes platform is running on arm64 processors, and using the alpine flavor of the flyway image would be appreciated since it is lighter.

Any reason to not make use of buildx for Alpine in the Makefile ?

and thanks for the great flyway product

Unfortunately, there does not seem to be a reliable officially maintained base image for a Java 11 JRE on Alpine for arm64.
As a result, using buildx would not work for this architecture. We are very aware of the desire for more architecture for the alpine image but until the correct base images are available, we can unfortunately not support them. Please keep an eye on our this repository or our Dockerhub page for any more developments.
Until then, the base Flyway image supports arm64 but, as you may have observed, it is not as lightweight.
