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、安裝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、配置防火墻

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、在安裝docker時(shí)，docker在/etc/下自動(dòng)生成一個(gè)docker文件，導(dǎo)致docker啟動(dòng)時(shí)不能創(chuàng)建/etc/docker目錄，不能生成/etc/docker/daemon.json 文件，所以不能啟動(dòng)，如果沒有該文件沒法同步docker鏡像，創(chuàng)建文件后需要重啟docker服務(wù)
[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管理主機(jī)上運(yùn)行
1、查看管理主機(jī)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、查看集群節(jié)點(diǎn)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

在節(jié)點(diǎn)主機(jī)上運(yùn)行

添加節(jié)點(diǎn)到docker集群
命令用法
docker swarm join –token <manger節(jié)點(diǎn)的token值> manger node ip:port

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