    本文是swarm docker集群的实施文档

    环境: centos 7

    192.168.1.23 swarm-manager rethinkdb controller swarm-agent consul-c1 registrator

    192.168.1.45 registrator swarm-agent consul-s3

    192.168.1.65 registrator swarm-agent consul-s2

    192.168.1.66 registrator swarm-agent consul-s2

    192.168.1.70 registrator  consul-c2 consul-template (nginx、haproxy)

    192.168.1.71 registrator  consul-c2 consul-template (nginx、haproxy)

    docker-engine 1.12.4

    一、安装 docker-engine 1.12.4 

    1、先检查是否安装旧版本docker

    1
    2
    3
    rpm -qa|grep docker
    如果有先卸载
    yum remove docker*

    2.编辑docker.repo文件,写入如下内容

    1
    2
    3
    4
    5
    6
    7
    cat >> /etc/yum.repos.d/docker-main.repo << EOF
    name=Docker main Repository
    baseurl=https://yum.dockerproject.org/repo/main/centos/7
    enabled=1
    gpgcheck=1
    gpgkey=
    EOF

    3.安装docker

    1
    yum -y install docker-engine

    4.关闭防火墙和selinux

    1
    2
    3
    4
    5
    systemctl stop firewalld.service
    systemctl disable firewalld.service
    关闭selinux
    sed -i 's/SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config 
    重启

    5.增加tcp监听端口

    1
    2
    修改/lib/systemd/system/docker.service
    sed -i 's/ExecStart=.*/ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -D -H tcp://0.0.0.0:2375/g' /lib/systemd/system/docker.service

    6.重启docker

    1
    2
    3
    4
    systemctl enable docker.service
    systemctl restart docker
    ps -ef|grep docker
    能看到docker启动及2375端口

    7、安装pip及docker api

    1
    2
    3
    yum -y install epel-release
    yum -y install python-pip
    pip install docker-py docker-compose

    二、配置consul cluster

    1、创建 consul 用户及组

    1
    2
    groupadd -g 1000 consul
    useradd -u 100 -g 1000 -s /sbin/nologin consul

    2、创建consul 数据存储文件夹

    1
    2
    mkdir -p /opt/consul/{data,conf}
    chown -R consul: /opt/consul

    3、拉取consul镜像

    1
    2
    docker pull progrium/consul
    提示:目录没有官方出consul镜像,以上consul镜像是星数最高的,也是consul官方推荐的第三方docker image

    4、启动consul server 192.168.1.66

                   echo "Usage: /etc/init.d/tmpl {start|stop|restart|force-reload}" >&2
                    exit 1
    esac

    9、设置开机启动

    1
    2
    3
    chmod +x nginx_ctmpl 
    chkconfig nginx_ctmpl on
    service nginx_ctmpl start

    七、测试是否自动发现

    1
    2
    docker run -ti -d -p :80 eboraas/apache-php 
    docker run -d -ti -p :80 nginx

    1、打开 http://192.168.1.66:8500/ui/#/dc1/services

    wKiom1hQ-d_hbARTAAD4abtS1z4077.png-wh_50

    2、http://192.168.1.23:8080/#/containers 

    查看shipyard  管理平台

    账号admin密码 shipyard

    wKioL1hQ-wuyjg2lAAIbesaRHzo687.png-wh_50

    3、haproxy 

    http://192.168.1.70:8888/admin?stats 

    http://192.168.1.71:8888/admin?stats

    账号:admin 密码admin

    wKioL1hQ-6uRI9yYAAKYPhux_rg092.png-wh_50

     

     

     

     

     

     

     

     

     

    最后:注意事项:consul  registrator 是基于端口发现的不映射端口是发现不了的

    consul 服务挂了整个宿主机运行应用将不可见。registrator 是基于镜像名加端口服务 

    镜像名称为nginx 多端口暴露  对外发现的服务名称nginx-80 单个端口暴露就是镜像名称为服务名

    像集群添加宿主机

    consul  registrator  swarm-agent   registrator   链接consul  端口请使用宿主机的consul  端口

    使用其它机器端口如果其它机器挂了这台宿主机的应用不可被发现
