分享一个k8s的mysql-router配置

因为用了k8s里搭建mysql-innodb-cluster，网上又好像没有对应mysql-router的配置，虽然也简单但能直接用最好啦，就简单修改了下弄了对应配置

好吧，直接代码。。。

Dockerfile（server.cicd:8089是私仓地址，自行更换呗）

FROM server.cicd:8089/common/percona-xtrabackup:8.0
LABEL maintainer="jiyilee"
RUN apt-get update
RUN apt-get  install -y net-tools
RUN apt-get  install -y iputils-ping
RUN apt-get purge -y percona-xtrabackup-80
RUN apt-get update && apt-get install -y mysql-shell
RUN apt-get install -y mysql-router

EXPOSE 6446
EXPOSE 6447

CMD ["bash", "-c", "tail -f /dev/null"]

install-router.sh（这里前提是在k8s里的mysql-service搭建好了mysql集群哦。。。好像是废话~）

#!/usr/bin/env bash
mysqlrouter --bootstrap root@mysql-primary-0.mysql-service:3306 -d myrouter --user=root

#myrouter/start.sh

#ps -ef|grep myroute

#mysql -u root -h 127.0.0.1 -P 6446 -p

deploy-mysql-router.yaml ingress-mysql-router.yaml service-nodeport.yaml（k8s文件，分三个、合一个你喜欢）

#创建service为mysql-router
apiVersion: v1
kind: Service
metadata:
  name: mysql-router
  namespace: default
spec:
  ports:
  - name: router-port
    #targetPort: 6446
    port: 6446
  clusterIP: None
  selector:
    app: mysql-router

#创建后端服务的pod
apiVersion: apps/v1
kind: Deployment

    spec:

        image: server.cicd:8089/common/mysql-router
        ports:

          containerPort: 6446

apiVersion: extensions/v1beta1

    kubernetes.io/ingress.class: "nginx"
spec:      
  rules:   
  - host: mysql-router.cicd   
    http:
      paths:       
      - path:       
        backend:    
          serviceName: mysql-router
          servicePort: 6446

---
apiVersion: v1
kind: Service
metadata:
  name: mysql-router-ingress-nginx
  namespace: default
  labels:
    app: mysql-router
spec:
  type: NodePort
  ports:
    - name: router-port
      port: 6446
      targetPort: 6446
      protocol: TCP
      nodePort: 36446
  selector:
    app: mysql-router

ok了， 其实整个东东很简单，当然直接mysql-router-service那type:NodePort也行。。。

再做个mysql-router.cicd域名指向，最后就可以这样访问了

mysql -u root -h mysql-router.cicd -P 36446 -p

PS,还是router简单，而不是什么mycat之类。
