Inject a PyPI mirror ==================== Use a custom PyPI mirror to build images. The default is to bind mount one from ~/.cache/image-create/pypi/mirror into the build environment. The element temporarily overwrites /root/.pip.conf and .pydistutils.cfg to use it. When online, the official pypi.python.org pypi index is supplied as an extra-url, so uncached dependencies will still be available. When offline, only the mirror is used - be warned that a stale mirror will cause build failures. To disable the pypi.python.org index without using --offline (e.g. when working behind a corporate firewall that prohibits pypi.python.org) set DIB\_NO\_PYPI\_PIP to any non-empty value. To use an arbitrary mirror set PYPI\_MIRROR\_URL=http[s]://somevalue/ Additional mirrors can be added by exporting PYPI\_MIRROR\_URL\_1=... etc. Only the one mirror can be used by easy-install, but since wheels need to be in the first mirror to be used, the last listed mirror is used as the pydistutils index. NB: The sort order for these variables is a simple string sort - if you have more than 9 additional mirrors, some care will be needed. A typical use of this element is thus: export PYPI\_MIRROR\_URL=http://site/pypi/Ubuntu-13.10 export PYPI\_MIRROR\_URL\_1=http://site/pypi/ [pypi-mirror](https://git.openstack.org/cgit/openstack-infra/pypi-mirror) 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://git.openstack.org/openstack-infra/pypi-mirror * cat << EOF > mirror.yaml cache-root: /home/USER/.cache/image-create/pypi/download mirrors: - name: openstack projects: - https://git.openstack.org/openstack/requirements output: /home/USER/.cache/image-create/pypi/mirror EOF * 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
