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 ```
