Docker 部署入门笔记

一、Docker 部署 1、配置docker yum源 [root@ docker]# cat /etc/yum.repos.d/docker-main.repo [docker-main-repo] name=Docker main Repository baseurl=https://get.daocloud.io/docker/yum-repo/main/CentOS/7 enabled=1 gpgcheck=1 gpgkey=https://get.daocloud.io/docker/yum/gpg

2、安装docker 17ce版本包 [root@ docker]# yum install docker-engine –y

3、查看docker版本 [root@ docker]# docker --version Docker version 17.05.0-ce, build 89658be

4、配置防火墙

firewall-cmd --add-port=2377/tcp --permanent

firewall-cmd --add-port=7946/tcp --permanent

firewall-cmd --add-port=7946/udp --permanent

firewall-cmd --add-port=4789/udp --permanent

firewall-cmd --reload**

5、在安装docker时，docker在/etc/下自动生成一个docker文件，导致docker启动时不能创建/etc/docker目录，不能生成/etc/docker/daemon.json 文件，所以不能启动，如果没有该文件没法同步docker镜像，创建文件后需要重启docker服务 [root@ docker]# cat /etc/docker/daemon.json { "insecure-registries":["docker-registry.istarshine.net.cn:5000"], "log-driver":"json-file", "log-opts":{"max-size":"1024m","max-file":"2"} } [root@ ~]# systemctl restart docker.service 二、加入docker集群

在manger管理主机上运行 1、查看管理主机token值 [root@filters5_191_6 ~]# docker swarm join-token worker To add a worker to this swarm, run the following command:

docker swarm join \ --token SWMTKN-1-4p4djbee1kqcss8x5prfzg6v01x0y7hfa7rqob6rffg6e2p2wq-278qafb9ptpqtfebr0kyngi0b \ 192.168.191.6:2377

2、查看集群节点列表 [root@filters ~]# docker node ls ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS 0y4ga216x49nd9zt821afe45p * filters5_191_6 Ready Active Reachable 56mgklq3iyf0ajioytmtr0b44 filters5_191_10 Ready Active b5mljua4e0tchrrk871ggbw7r filters5_191_7 Ready Active Reachable gxm1gvh8lx2eja36a4cms9w98 filters5_182_212 Ready Active hgweoxc5vmy9g30uyozmbumhj filters5_182_213 Ready Active lluom23ugtfuiwphcye2frbmd filters5_182_215 Ready Active om0ezdbqzdvavn8z8d844osbo filters5_182_214 Ready Active t00tu1qs7wbll2fg2accsx7wf filters5_191_4 Ready Active Leader tk89xphvsg16rz7b7l6lam4xv filters5_191_9 Ready Active xbcx4hx2lq3ji8zog2ayzctat filters5_191_8 Ready Active Reachable y3pnrw9jt69vkfiuxrs0co7ke filters5_191_5 Ready Active Reachable

在节点主机上运行

添加节点到docker集群 命令用法 docker swarm join --token <manger节点的token值> manger node ip:port

[root@dockernode~]#docker swarm join --token SWMTKN-1-4p4djbee1kqcss8x5prfzg6v01x0y7hfa7rqob6rffg6e2p2wq-278qafb9ptpqtfebr0kyngi0b 192.168.191.6:2377
