通过kubernetes构建ela服务

一、kubernetes 通过yaml 创建pod与service

apiVersion: extensions/v1beta1
kind: Deployment
metadata:name: ela
spec:replicas: 1template:metadata:labels:name: elaspec:containers:- name: elaimage: 59.61.79.157:5000/elatty: trueports:- containerPort: 9200- containerPort: 8080volumeMounts:- name: ssl-certsmountPath: /eladatavolumes:- name: ssl-certshostPath:emptyDir: {}
---
apiVersion: v1
kind: Service
metadata:name: elalabels:name: ela
spec:type: NodePortports:- port: 8080targetPort: 8080#  nodePort: 30001protocol: TCPname: elasql- port: 9200targetPort: 9200protocol: TCPname: elasselector:name: ela

二、kubectl常用命令

kubectl delete deployment *  删除部署
kubectl create -f k8s.yaml 创建服务
kubectl  apply -f k8s.yaml  更新服务
kubectl get pods 查看容器
kubectl get deployment 查看部署
kubectl get service 查看服务
kubectl get node 查看集群
kubectl get pods -o wide 查看服务运行在哪个节点 

 三、其他

删除镜像：（非管理员勿操作）docker exec registry  rm -rf /var/lib/registry/docker/registry/v2/repositories/<镜像名>docker exec registry bin/registry garbage-collect /etc/docker/registry/config.yml详情： #centos7.2 images not ifconfig commod   #yum -y install net-tools
