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.
