    Description

      So this happened while testing other flakiness issues in docker containers:

      "docker build" command pulls from external registry, and apparently if that registry is unresponsive, then our builds fail.

      We can cache the two images we need (ubuntu:16.04 and ubuntu:18.04) as tarballs and feed them to "docker build", according to this technique. On my machine:

      # docker pull ubuntu:16.04
# docker save -o ubuntu:18.04.tar ubuntu:18.04

      Save the tarball somewhere, and then on the build host:

      # docker load -i ubuntu:18.04.tar
