arm64 image is not actually arm64; binaries are x86-64

This is probably the same problem as #35, but that seems to be focused on arm32; arm64 is also affected.

Can confirm, doesn't work on a Raspberry Pi 4 with aarch64

 $ uname -m
aarch64
 $ docker run --rm osixia/keepalived:2.0.20
standard_init_linux.go:211: exec user process caused "exec format error"

[Heire]

Indeed, wrong architecture. was looking for an arm version.

[linkvt]

@Heire I fixed it with my pull request, maybe you can test my image https://hub.docker.com/r/linkvt/osixia_keepalived/tags?page=1&ordering=last_updated (stable tag) and maybe comment in referenced PR to confirm if it works for you.

[SiqingYu]

Confirmed. The arm64/v8 image is actually amd64.

[lettore]

I found this issue too, I'm rebuilding the images with latest Alpine and Keepalived, you can find it at https://hub.docker.com/r/lettore/keepalived/tags tag is x.xx-y.yy.y where x is Alpine version and y Keepalived version.

[runfabi]

Can confirm pulling different digests also results in pulling the non arm image

[MarcelloPercoco]

Hi.

Confirmed even for armv7 image
