Calico is a virtual network infrastructure that we use to manage kubernetes networking.


We don't actually build calico but package it's components from upstream binary releases.

Because of that, you will need to set HTTP proxy variables for internet access on the build host.

The general process to follow is:*Check out operations/debs/calico on your workstation

  • Decide if you want to package a new master (production) or future (potential next production) version
  • Create a patch to bump the debian changelog
export NEW_VERSION=3.16.5 # Calico version you want to package
dch -v ${NEW_VERSION}-1 -D unstable "Update to v${NEW_VERSION}"
git commit debian/changelog

# If you're packaging a new future version, make sure to submit the patch to the correct branch
git review future
git checkout future # If you want to build a new version not directly to be released to production

# Ensure you allow networking in pbuilder
# This option needs to be in the file, an environment variable will *not* work!
echo "USENETWORKING=yes" >> ~/.pbuilderrc

# Build the package
https_proxy=http://webproxy.$(hostname -d):8080 DIST=<dist> pdebuild


The Debian Packages

# On apt1001, copy the packages from the build host
rsync -vaz deneb.codfw.wmnet::pbuilder-result/<dist>-amd64/calico*<PACKAGE VERSION>* .

# If you want to import a new production version, import to component main
sudo -i reprepro -C main --ignore=wrongdistribution include <dist>-wikimedia /path/to/<PACKAGE>.changes

# If you want to import a test/pre-production version, import to component calico-future
sudo -i reprepro -C component/kubernetes-future --ignore=wrongdistribution include <dist>-wikimedia /path/to/<PACKAGE>.changes

The Docker Images

Calico also includes a bunch of docker images which need to be published into our docker registry. To simplify the process, the packaging generates a debian package named "calico-images" that includes the images as well as a script to publish them:

# On the build host, extract the calico-images debian package
tmpd=$(mktemp -d)
dpkg -x /var/cache/pbuilder/result/<dist>-amd64/calico-images_<PACKAGE_VERSION>_amd64.deb $tmpd

# Load and push the images
sudo CALICO_IMAGE_DIR=${tmpd}/usr/share/calico ${tmpd}/usr/share/calico/
rm -rf $tmpd
