| # BGP support | ||
|
|
||
| Kube-OVN supports broadcast pod ips to external networks by BGP protocol. | ||
| To enable BGP announce function, you need to install kube-ovn-speaker and annotate pods that need to be exposed. | ||
|
|
||
| ## Install kube-ovn-speaker | ||
|
|
||
| 1. Download `kube-ovn-speaker` yaml | ||
|
|
||
| ```bash | ||
| wget https://github.com/alauda/kube-ovn/blob/master/yamls/speaker.yaml | ||
| ``` | ||
|
|
||
| 2. Modify the args in yaml | ||
|
|
||
| ```bash | ||
| --neighbor-address=10.32.32.1 # The router address that need to establish bgp peers | ||
| --neighbor-as=65030 # The AS of router | ||
| --cluster-as=65000 # The AS of container network | ||
| ``` | ||
|
|
||
| 3. Apply the yaml | ||
|
|
||
| ```bash | ||
| kubectl apply -f speaker.yaml | ||
| ``` | ||
|
|
||
| ## Annotate pods that need to be exposed | ||
|
|
||
| ```bash | ||
| # Enable BGP | ||
| kubectl annotate pod sample ovn.kubernetes.io/bgp=true | ||
|
|
||
| # Disable BGP | ||
| kubectl annotate pod perf-ovn-xzvd4 ovn.kubernetes.io/bgp- | ||
| ``` |
