Associate an ENI with a pod - User Guide for Kubernetes Clusters| Alibaba Cloud Documentation Center

This topic describes how to associate an Elastic Network Interface (ENI) with a pod.

Background information

When you create a Kubernetes cluster, you need to select Network Plugin as Terway. For more information, see Create an ACK cluster.
If you use a Kubernetes cluster that is installed with the Terway network plugin, you must make sure that the Terway plugin is V1.0.0.1 or later.
Note
1. Log on to the Container Service console, click Clusters under the Kubernetes menu.
2. In the action column of the target cluster, choose More > Addon Upgrade.
3. On the Addon Upgrade page, view your current version of Terway.
4. Determine whether to upgrade according to Current Version and Upgradeable Version. If you want to upgrade Terway, click Upgrade in the action column.

Procedure

Log on to the Container Service console.
In the left-side navigation pane under Container Service-Kubernetes, choose Application > Deployment.

In the upper-right corner, click Create by Template.

You can use the following YAML template to create a pod:

apiVersion: v1
kind: Pod
metadata:
  name: terway-pod
  labels:
    app: nginx
spec:
  containers:
  - name: nginx
    image: nginx
    ports:
    - containerPort: 80
    resources:
      limits:
        aliyun/eni: 1

Result

In the left-side navigation pane under Container Service-Kubernetes, choose Application > Pods.
The pod named terway-pod is displayed.
In the left-side navigation pane under Kubernetes, click Clusters.
Click the name of the target cluster to view the cluster details.
In the Cluster Resource area, click VPC to view the VPC CIDR block of the cluster.
Run the following command to obtain the IP address of the deployed pod and verify that the IP address is within the VPC CIDR block of the cluster:
```
$ kubectl get pod -o wide
```
