Calico

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

Building

Following the integration guide there are a few things we need to rebuild, in order to stick to our policy of "internal builds only":

- the calico/node container - the calicoctl cli tool (which gets built as part of the calico/node build pipeline) - the calico-cni CNI plugins - the base cni plugins we'll be using

The next few sections will detail how to do each of these things.

calicoctl (and calico/node)

We keep a cloned/modified repository at operations/calico-containers. Please note that calico has renamed their repo to "calicoctl" in the meanwhile.

Download the needed version using the debian/repack scipt, then import it using gbp

# In the directory where you cloned calico-containers
/srv/calico $ debian/repack 1.2.1
...
/srv/calico $ gpb import-orig ../calico-containers-1.2.1.tar.xz
....
/srv/calico $ dch -v "1.2.1-1~wmf1"
/srv/calico $ git add debian/changelog && git commit -m "Updating debian version"
# Now build calicoctl; this will also apply the needed patches to the dockerfiles
/srv/calico $ gbp buildpackage
...
/srv/calico $ make calico-node node-test-containerized

The resulting calico-node container will need to be tagged appropriately and pushed to the registry.

calico-cni

Download the needed version using the debian/repack script, then import it using gbp

# In the directory where you cloned operations/calico-cni
/srv/calico-cni $ debian/repack 1.8.3

Please note that this will result in a "dirty" package as we're downloading all go dependencies directly and not "the debian way". This might change once the number of natively supported libraries becomes larger
