这里是把Deployment和Services在一个文件中实现了。也可以分为两个文件来实现。

完整的文件如下:
1 | kubectl create -f kube-tomcat.yaml |
---|
查看创建的deployment:、
1 | kubectl get deployment |
---|
查看这个deployment的详情:
1 | kubectl describe deployment kube-tomcat |
---|
查看创建的service:
1 | kubectl get service |
---|
查看这个service的详情。
1 | kubectl describe service kube-tomcat |
---|
查看创建的pod:
1 | kubectl get pod |
---|
查看其中一个pod的详情。
pod详情这里的IP是nodes中的虚拟IP。该虚拟IP可以去nodes里面使用ifconfig查看。
1 | kubectl describe pod kube-tomcat-1115055280-tk1f8 |
---|
在nodes上查看创建的容器:
这里一定要指定namespaces和services。
注意在请求中的IP应该是master所在的IP。返回成功。可以使用Postman来进行接口测试,测试通过表示部署成功。
