Size of release

120 MiB for each of the three packages

Which indexes

PyPI only.

Reasons for the request

These packages contains one or more xz-compressed tarball of "kernel runner environment" Docker volume archives for several Linux distributions optimized for running a small coordinator daemon ("kernel runner") inside arbitrary Docker images on Backend.AI clusters.

For instance, backend.ai-krunner-ubuntu package contains environment images for Ubuntu 16.04 and 18.04. Each tar.xz archives takes about 20-30 MiB, and we are going to add a few more in the near future (e.g., Ubuntu 20.04 / CentOS 8 / Alpine 3.11).

Of course, we won't accumulate the archives infinitely but keep only latest 2 or 3 versions of each Linux distributions. We also have been trying to minimize the size using Docker's multi-stage builds, xz compression, and bundling only the isolated Python and package directory (each volume archives are mounted as /opt/backend.ai in user containers).

Still, adding more packages and distribution supports to the environment volume archives may touch the package size limit of 60 MiB, and I believe that 120 MiB would be good for now. I am writing this request since our newly built backend.ai-krunner-alpine package just hit 60.1 MiB and I got upload failure.

I've set the upload limit for all three projects to 120 MB on PyPI. Please be mindful of the frequency of releases at that size.

Thanks! I'll do my best to keep the package sizes small.
