  1. # A dockerfile which builds a docker image for building a debian package for
  2. # synapse. The distro to build for is passed as a docker build var.
  3. #
  4. # The default entrypoint expects the synapse source to be mounted as a
  5. # (read-only) volume at /synapse/source, and an output directory at /debs.
  6. #
  7. # A pair of environment variables (TARGET_USERID and TARGET_GROUPID) can be
  8. # passed to the docker container; if these are set, the build script will chown
  9. # the build products accordingly, to avoid ending up with things owned by root
  10. # in the host filesystem.
  11. # Get the distro we want to pull from as a dynamic build variable
  12. ARG distro=""

  16. # This is only really needed on focal, since other distributions we
  17. # care about have a recent version of dh-virtualenv by default. Unfortunately,
  18. # it looks like focal is going to be with us for a while.
  19. #
  20. # (focal doesn't have a dh-virtualenv package at all. There is a PPA at
  21. # https://launchpad.net/~jyrki-pulliainen/+archive/ubuntu/dh-virtualenv, but
  22. # it's not obviously easier to use that than to build our own.)
