Add tag support for docker images

[telmich]

This is an amazing and easy container, I love it. For k8s setups, it would be great if this container had some more tags / different versions, like:

• alpine:3.14
• debian:...

While it is not saying which openssh it is, it is at least clear that it is the openssh that was available in alpine:3.14. This would also make it easier for upgrading in k8s environments, as the :latest tag needs to be pulled every time and cannot be controlled whether this is changed.

I could contribute two small scripts, if they would be merged, like:

• debian.sh <version> building and creates the images based on debian:version
• alpine.sh ... same same

Does that make sense?

ping @atmoz - is this not of interest?

Seconded @telmich, all good points 👍

The way I see it, the current release "strategy" for atmoz/sftp provides zero traceability with regards to changes between releases ~ ie. what's changed between the last versioned release from 4 years ago, ex. alpine-3.7, and the 20h old unversioned alpine-tag ? (only the maintainers might know)

This approach is to unpredictable for me ~ resulting in a hard pass until remedied 🤓

Are there any updates regarding this issue? Is this correct, that using

1. atmoz/sftp:alpine Tag uses the alpine:latest as base image
2. atmoz/sftp:debian Tag uses the debian:bullseye as base image

If yes, using the debian image gives more predictability, but it's a bit bigger in size.
