Docker rancher 部署

Docker-rancher

环境 centos7.4 , Docker version 17.12.0-ce

下载docker镜像

docker pull mysql:5.7
docker pull rancher/server:latest
docker images

#运行MySQL容器

 #创建挂载目录
mkdir -p /data/mysql/{datadir,conf.d,logs}

 #创建mysql容器,设置密码sql2018
DBPass=sql2018
docker run --name mysqldb -p 3306:3306 \
  -v /data/mysql/datadir:/var/lib/mysql \
  -v /data/mysql/conf.d:/etc/mysql/conf.d \
  -e MYSQL_ROOT_PASSWORD=$DBPass -d mysql:5.7

 #查询测试
docker ps -l
docker exec -it mysqldb mysql -p$DBPass -e "show databases;"

 #创建库并授权(库,用户,密码都为cattle)
docker exec -it mysqldb mysql -p$DBPass -e "
  create database if not exists cattle collate = 'utf8_general_ci' character set = 'utf8';
  grant all on cattle.* to 'cattle'@'%' identified by 'cattle';
  grant all on cattle.* to 'cattle'@'localhost' identified by 'cattle';
  flush privileges;show databases;"

#运行rancher容器

IP=172.16.50.26  #本机IP
Port=8090  #rancher web端口
docker run -d --name rancher --link=mysqldb:db \
--restart=unless-stopped -p $Port:8080 -p 9345:9345 rancher/server:latest \
--db-host db --db-port 3306 --db-user cattle --db-pass cattle --db-name cattle \
--advertise-address $IP

等几分钟,当数据表超过100行时,可以浏览器打开了

 #显示为109时安装完成
docker exec -it mysqldb mysql -u"cattle" -h localhost -p"cattle" -e "use cattle;show tables;" |wc -l
echo "浏览器访问 $IP:$Port "

#添加主机(节点)

基础架构——主机——添加主机(保存)——复制第5部分代码，在其它docker节点执行

本次安装，添加节点代码

sudo docker run --rm --privileged -v /var/run/docker.sock:/var/run/docker.sock \
 -v /var/lib/rancher:/var/lib/rancher rancher/agent:v1.2.9  \
 http://172.16.50.26:8090/v1/scripts/EBB906FD4DA3BFB93D88:1514678400000:68jkNNZXjsOp2zDIwxHCb4MkjI8

rancher安装k8s(仅供测试)
