Thanks for doing this

@xmikus01 as #1500 was resolved in #1510, would you like to rebase added-alpine3.14 branch base on the latest main branch, so that we can pass the CI and get it merged? Thanks!

[xmikus01]

Build is broken for Alpine variants, see #1514.

Looks like NODE_VERSIONs might be bumped to the latest versions available atm ⏲️

[PeterDaveHello]

The build issue seem to be fixed?

[nschonni]

@PeterDaveHello yes, this has the fix from #1510 applied already

[xmikus01]

@PeterDaveHello @nschonni Ready to merge.
