Inject a PyPI mirror

Bind mounts a PyPI mirror from ~/.cache/image-create/pypi/mirror into the build environment and temporarily overwrites /root/.pip.conf and .pydistutils.cfg to use it.

When online, the master pypi index is supplied as an extra-url, so uncached dependencies will still be available. When offline, only the mirror is used - a stale mirror will cause build failures.

jeepyb can be useful in making a partial PyPI mirror suitable for building images. For instance:

  • sudo apt-get install libxml2-dev libxslt-dev libmysqlclient-dev libpq-dev
    libnspr4-dev pkg-config libsqlite3-dev libzmq-dev libffi-dev libldap2-dev
    libsasl2-dev

  • pip install git+https://github.com/openstack-infra/jeepyb

  • cat << EOF > mirror.yaml cache-root: /home/USER/.cache/image-create/pypi/download

    mirrors:

  • mkdir -p /home/USER/.cache/image-create/pypi/{download,mirror}

  • run-mirror -b remotes/origin/master --verbose -c mirror.yaml

    This creates and updates the mirror.

If you have additional packages that are not identified in the global openstack requirements project, you can include them:

  • pip install -d ~/.cache/image-create/pypi/download/pip/openstack
    heat-cfntools distribute os-apply-config run-mirror -b remotes/origin/master --verbose -c mirror.yaml --no-download
