Could you also update the alpine version in docker/Dockerfile.revad-eos?

[SamuAlfageme]

@vascoguita have you tried running an alpine-built revad on CentOS7 successfully after aa93c90 ?

The image built correctly, but there were many static linking issues hard to fix when using alpine rather than the EOS image for the builder step.

[vascoguita]

Oh I see, I'll test it and if it fails I'll try with -extldflags=-static in the ldflags.
Hold on

[SamuAlfageme]

@vascoguita I can save you some time if you check #1705 (when I originally used alpine on the builder step) and #1718 (where I restricted the static linking to the build-ci target)

[vascoguita]

I've just tested the revad image built from Dockerfile.revad-eos and apparently it's working: https://github.com/vascoguita/reva/actions/runs/4374000858/jobs/7652883570
(Ignore the job name 'docker (docker/Dockerfile.revad) / docker', the steps are building and testing Dockerfile.revad-eos)

[SamuAlfageme]

@vascoguita looks promising. I'm not sure to which extent these tests check all the services in reva and how they interact with the eos binary but this might be reviewed in the future if issues arise.

I'll rebase and include it as well on the -eos image. Thanks a lot for checking!
