Calico

Check if the calico-node container is running

docker ps | grep calico

The calicoctl command allows to check the status of the network workloads.

• Check the status of Calico nodes

calicoctl node status

or for versions prior v1.0.0:

calicoctl status

• Show the configured network subnet for containers

calicoctl get ippool -o wide

or for versions prior v1.0.0:

calicoctl pool show

• Show the workloads (ip addresses of containers and their located)

calicoctl get workloadEndpoint -o wide

and

calicoctl get hostEndpoint -o wide

or for versions prior v1.0.0:

calicoctl endpoint show --detail

Optionnal : Define network backend

In some cases you may want to define Calico network backend. Allowed values are 'bird', 'gobgp' or 'none'. Bird is a default value.

To re-define you need to edit the inventory and add a group variable calico_network_backend

calico_network_backend: none

Optionnal : BGP Peering with border routers

In some cases you may want to route the pods subnet and so NAT is not needed on the nodes. For instance if you have a cluster spread on different locations and you want your pods to talk each other no matter where they are located. The following variables need to be set: peer_with_router to enable the peering with the datacenter's border router (default value: false). you'll need to edit the inventory and add a and a hostvar local_as by node.

node1 ansible_ssh_host=95.54.0.12 local_as=xxxxxx

Cloud providers configuration

Please refer to the official documentation, for example GCE configuration requires a security rule for calico ip-ip tunnels. Note, calico is always configured with ipip: true if the cloud provider was defined.
