@ridwanmsharif sles 12 does not appear to be building correctly. When I try to build the sles12 docker target locally or test with kokoro I get an error

#5 29.18 Problem: systemd-devel-228-27.2.x86_64 requires libsystemd0 = 228-27.2, but this requirement cannot be provided

This shouldn't be set as this is a 404 non existent link.

When google technical writer has the documentation, we will set this public_url in post agent release jobs :)

Oh great catch! Will fix this as part of the flink metrics PR. Also made a pass through the other PRs that added this and commented on them too.
