以一个nginx的service和deployment来验证集群功能
创建启动文件
mkdir /opt/k8s/yml
cd /opt/k8s/yml
cat > nginx.yml << EOF
apiVersion: v1
kind: Service
metadata:
name: nginx
labels:
app: nginx
spec:
type: NodePort
selector:
app: nginx
ports:
- name: http
port: 80
targetPort: 80
nodePort: 8080
---
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
spec:
selector:
matchLabels:
app: nginx
replicas: 1
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:1.9.1
ports:
- containerPort: 80
EOF
启动服务
kubectl create -f nginx.yml
第一次启动时需要下载k8s.gcr.io/pause:3.1镜像，国内无法直接下载，造成服务无法启动，通过下面操作来解决
docker pull kubeimage/pause:3.1
docker tag kubeimage/pause:3.1 k8s.gcr.io/pause:3.1
观察服务启动情况
root@master:/opt/k8s/yml# kubectl get service -o wide
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE SELECTOR
kubernetes ClusterIP 10.254.0.1 <none> 443/TCP 41h <none>

root@master:/opt/k8s/yml# kubectl get pod -o wide
