I don;'t think this should be done all in one shot because it might break people's build. We should be adding the version without changing the default

[jnoordsij]

I basically followed the commit from the previous Alpine version update (3760675), in which the default version also was updated immediately.

Also I think updating default is a pretty reasonable thing to do (and is done by more official images), because if you need a specific OS version you probably should have already tagged it in your own pipeline, similar to using latest vs. a specific version.

But this effectively drops support fort Alpine 3.14 for all version, forcing everyone who want a future security update in NOde, to also update their Alpine version

[jnoordsij]

Yeah, I think that's open to maintainers to decide how many OS versions you want to support. Alpine does still provide security support for 3.14 (and 3.13 even, see https://alpinelinux.org/releases/), so you might keep some more versions if preferred. Happy to adjust for that if wanted.

Any consensus on this? 🤔

@LaurentGoderre see the previous discussion #1615 (comment) in that DockerHub doesn't want us supported more than 2 majors for Alpine at one time, so we dropped the oldest last time.

@jnoordsij hold off on rebasing this for now, till #1733 (comment) lands

Saw #1733 just got merged, so rebased this. Let me know if anything else is needed.

We need to ship 🚢 it asap 😀
