* rename ansible groups to use _ instead of -
k8s-cluster -> k8s_cluster
k8s-node -> k8s_node
calico-rr -> calico_rr
no-floating -> no_floating
Note: kube-node,k8s-cluster groups in upgrade CI
need clean-up after v2.16 is tagged
* ensure old groups are mapped to the new ones

# Kube-OVN
|
|
|
|
Kube-OVN integrates the OVN-based Network Virtualization with Kubernetes. It offers an advanced Container Network Fabric for Enterprises.
|
|
|
|
For more information please check [Kube-OVN documentation](https://github.com/alauda/kube-ovn)
|
|
|
|
**Warning:** Kernel version (`cat /proc/version`) needs to be different than `3.10.0-862` or kube-ovn won't start and will print this message:
|
|
|
|
```bash
|
|
kernel version 3.10.0-862 has a nat related bug that will affect ovs function, please update to a version greater than 3.10.0-898
|
|
```
|
|
|
|
## How to use it
|
|
|
|
Enable kube-ovn in `group_vars/k8s_cluster/k8s_cluster.yml`
|
|
|
|
```yml
|
|
...
|
|
kube_network_plugin: kube-ovn
|
|
...
|
|
```
|
|
|
|
## Verifying kube-ovn install
|
|
|
|
Kube-OVN run ovn and controller in `kube-ovn` namespace
|
|
|
|
* Check the status of kube-ovn pods
|
|
|
|
```ShellSession
|
|
# From the CLI
|
|
kubectl get pod -n kube-ovn
|
|
|
|
# Output
