Docker 部署入门大全

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、ASP站长网安装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
