docker swarm集群部署

alenas

1. 集群概况
master-node1          192.168.47.140
node2                192.168.47.142
node3                192.168.47.142
2. 系统版本
[root@master-node1 ~]# cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)
[root@master-node1 ~]# uname -a
Linux master-node1 3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22 21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
3. 系统初始化
关闭selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
setenforce 0
关闭防火墙
systemctl disable firewalld
systemctl stop firewalld
修改hostname
hostnamectl set-hostname master-node1
4. 安装docker
wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo
sed -i 's#download.docker.com#mirrors.ustc.edu.cn/docker-ce#g' /etc/yum.repos.d/docker-ce.repo
yum install docker-ce -y
5. 修改docker启动文件，监听端口，启动docker
vim /usr/lib/systemd/system/docker.serviceExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://10.0.0.100:2375systemctl daemon-reloadsystemctl enable docker.service systemctl restart docker.service
6. master上启动etcd、swarm-manage
docker run -ti -d -p 4001:4001 -p 7001:7001 --restart=always --name shipyard-discovery docker.io/microbox/etcd -name discovery
docker run -ti -d -p 2376:2375 --restart=always --name shipyard-swarm-manager swarm:latest manage --host tcp://0.0.0.0:2375 etcd://192.168.47.140:4001
7. 在所有节点安装swarm-agent
master-node1        docker run -ti -d --restart=always --name shipyard-swarm-agent swarm:latest join --addr 192.168.47.140:2375 etcd://192.168.47.140:4001
node2                docker run -ti -d --restart=always --name shipyard-swarm-agent swarm:latest join --addr 192.168.47.141:2375 etcd://192.168.47.140:4001
node3                docker run -ti -d --restart=always --name shipyard-swarm-agent swarm:latest join --addr 192.168.47.142:2375 etcd://192.168.47.140:4001
8. 在任意节点上查看节点状态
[root@master-node1 ~]# docker run --rm swarm list etcd://192.168.47.140:4001
time="2018-04-24T06:55:41Z" level=info msg="Initializing discovery without TLS"
192.168.47.140:2375
192.168.47.141:2375
192.168.47.142:2375
9. 安装Shipyard
docker pull rethinkdb
docker pull shipyard/shipyard
docker run -ti -d --restart=always --name shipyard-rethinkdb -p 8082:8080 -p 28015:28015 -p 29015:29015 -v /opt/rethinkdb:/data rethinkdb
访问：http://192.168.47.140:8082/

docker run -ti -d --restart=always --name shipyard-controller --link shipyard-rethinkdb:rethinkdb --link shipyard-swarm-manager:swarm -p 8081:8080 shipyard/shipyard server -d tcp://swarm:2375
访问：http://192.168.47.140:8081/         默认用户名密码：admin/shipyard
