Description
Adds GCE Alias IP support for flannel. The feature is enabled by setting
FLANNEL_GCE_NETWORK_USE_ALIAS_IP=true.The code paths between static route support and alias IP support were separated in
RegisterNetwork()to avoid crossing any lines between the two features. Static routes should still work and remain the default.The bulk of the changes are under
backend/gceand only a few hundred lines, but the GCP SDK required a large update invendorto support the alias IP part of the API.As mentioned in the code, the following needs to be set in
/etc/default/instance_configs.cfgbefore the installation process:and then run
systemctl restart google-guest-agent.service. This prevents the google guest agent from installing a conflicting route that will break pod networking.Todos
