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](http://docs.projectcalico.org/v1.5/getting-started/docker/installation/gce) requires a security rule for calico ip-ip tunnels. Note, calico is always configured with ``ipip: true`` if the cloud provider was defined.
