Building debian-stretch-jenkins on ARM currently results in a few
libraries getting installed for the i386 architecture. This results in
the following build failures for master-osmo-trx and master-osmo-pcu:
checking for LIBGNUTLS... no
configure: error: Package requirements (gnutls >= 2.12.0) were not met:
No package 'gnutls' found
It is weird that we are only seeing this now, the dpkg-line has been in
debian-stretch-jenkins since the Dockerfile was added to osmo-ci four
years ago in Icb0406f96b0c18e77be51ad8317c2668fb23a45e. I'm also
wondering why it was added in the first place, and if we need it
anymore. In any case, running this on anything but x86_64 does not make
sense, so disable it there.
Instead of hardcoding laforge's username in all FROM statements in the
Dockerfiles, make use of the USER variable (as passed through by the
"make/Makefile" with "docker build --build-arg USER=..."). Thanks to
fixeria for proposing this fix!
This requires running docker-ce, old versions of docker (such as the
one in the official repositories of the latest Fedora) don't support
variables in the FROM line. But docker-ce can be installed after
adding docker's 3rd party repositories.
