Node 10.14 and 10.15 slim images are not being built for ARM64

[carlosedp]

The Node 10.14 and 10.15 images are not being built for ARM64 on -slim variants as can be seen on https://github.com/docker-library/official-images/blob/master/library/node.
The "full" stretch images are Ok.

That's because it's not in the support architectures list: https://github.com/nodejs/docker-node/blob/master/10/architectures#L4

@PeterDaveHello @chorrell @tianon does anyone know if there's a reason for this?

[chorrell]

No idea. The matrix of what is supported by Debian and Node is confusing.

[chorrell]

fwiw I can't think of a reason to not add ARM64 to the slim images given that it already works on stretch

[LaurentGoderre]

@chorrell especially since other versions have it.

[LaurentGoderre]

@chorrell should we also add ppc64le and s390x?

[chorrell]

I’m assuming so, but I’m not really sure. I think they were only ever excluded for jessie
