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 use an arbitrary mirror set PYPI\_MIRROR\_URL=http[s]://somevalue/
[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
