# Provisioning Pod Network
|
||
|
|
|
||
|
|
Container Network Interface (CNI) is a standard interface for managing IP networks between containers across many nodes.
|
||
|
|
|
||
|
|
We chose to use CNI - [weave](https://www.weave.works/docs/net/latest/kubernetes/kube-addon/) as our networking option.
|
||
|
|
|
||
|
|
|
||
|
|
### Deploy Weave Network
|
||
|
|
|
||
|
|
Deploy weave network. Run only once on the `master-1` node. You will see a warning, but this is OK.
|
||
|
|
|
||
|
|
[//]: # (host:master-1)
|
||
|
|
|
||
|
|
On `master-1`
|
||
|
|
|
||
|
|
```bash
|
||
|
|
kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"
|
||
|
|
```
|
||
|
|
|
||
|
|
Weave uses POD CIDR of `10.32.0.0/12` by default.
|
||
|
|
|
||
|
|
## Verification
|
||
|
|
|
||
|
|
[//]: # (sleep:45)
|
||
|
|
|
||
|
|
List the registered Kubernetes nodes from the master node:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
kubectl get pods -n kube-system
|
||
|
|
```
|
||
|
|
|
||
|
|
> output
|
||
|
|
|
||
|
|
```
|
||
|
|
NAME READY STATUS RESTARTS AGE
|
||
|
|
weave-net-58j2j 2/2 Running 0 89s
|
||
|
|
weave-net-rr5dk 2/2 Running 0 89s
|
||
|
|
```
|
||
|
|
|
||
|
|
Once the Weave pods are fully running which might take up to 60 seconds, the nodes should be ready
|
||
|
|
|
||
|
|
```bash
|
||
|
|
kubectl get nodes
|
||
|
|
```
|
||
|
|
|
||
|
|
> Output
|
||
|
|
|
||
|
|
```
|
||
|
|
NAME STATUS ROLES AGE VERSION
|
||
|
|
worker-1 Ready <none> 4m11s v1.24.3
|
||
|
|
worker-2 Ready <none> 2m49s v1.24.3
|
||
|
|
```
