二进制部署K8s集群第13节之验证集群

一、创建一个资源配置清单nginx容器在hdss7-21或hdss7-22任意一个节点上创建一个资源配置清单

cat > /root/nginx-ds.yaml <<'eof' apiVersion: apps/v1 kind: DaemonSet metadata: name: my-nginx spec: selector: matchLabels: app: my-nginx template: metadata: labels: app: my-nginx spec: containers: - name: my-nginx image: harbor.od.com/public/nginx:v1.7.9 ports: - containerPort: 80 eof kubectl create -f /root/nginx-ds.yaml

二、集群检查在hdss7-21 curl 172.7.21.2在hdss7-22 curl 172.7.22.2
