Verifying K8s + Docker Deployment

001

Checking nodes in the K8s cluster

Deploy the network by referring to chapter Environment Requirements.

1. Install Docker by referring to chapter Installing Docker.
2. Install K8s, configure the master node, and add the compute nodes to the cluster by referring to chapter Installing K8s.

Check the cluster nodes on the master node. The expected result is displayed.

kubectl get nodes

All compute nodes are added to the cluster. For details, see the screenshot in the "Remarks" row.

The master node provisions containers to the Kunpeng nodes.

Deploy the network by referring to chapter Environment Requirements.

The Kunpeng servers have been added to the cluster and are in the Ready state.

1. Write the YAML file on the master node.

   vi nginx-arm.yaml

   apiVersion: apps/v1
   kind: Deployment
   metadata:
     name: nginx-arm-deployment
   spec:
     selector:
       matchLabels:
         app: arm64v8_nginx
     replicas: 40
     template:
       metadata:
         labels:
           app: arm64v8_nginx
         annotations:
           cni: "flannel"
       spec:
         containers:
         - name: nginx
           image: nginx:latest
           ports:
           - containerPort: 80
         nodeSelector:
           kubernetes.io/arch: arm64

2. On the master node, create pods based on the YAML file.

   kubectl apply -f nginx-arm.yaml

3. Check the pod status on the master node. Expected result 1 is displayed.

   kubectl get pods -o wide -A

4. Log in to the Kunpeng nodes where the pods are located and check the architecture of the Docker image. Expected result 2 is displayed.

   docker inspect nginx

1. The nodes where the pods of Nginx reside are the Kunpeng nodes. For details, see the screenshot in the "Remarks" row.
2. The system architecture is Arm64. For details, see the screenshot in the "Remarks" row.
