AWS上构建Docker Swarm

1、准备机器
manager-ha-master 172.31.72.142
manager-ha-backup 172.31.82.187
manager3 172.31.61.130
woker-smarthome  172.31.80.14
woker-justfitv2 172.31.76.147
work-oss 172.31.56.103

2、Docker Ce版安装
    yum remove -y docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-selinux \
                  docker-engine-selinux \
                  docker-engine
                  
   yum install -y yum-utils \
      device-mapper-persistent-data \
      lvm2
      
      yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo
    
    yum-config-manager --disable docker-ce-edge
    
    yum install docker-ce -y
    
3、启动Docker
 systemctl enable docker && systemctl start docker
 systemctl status docker
 
4、manager机器1：
 docker swarm init --advertise-addr 172.31.72.142
 
5、为mananger1添加worker：
 docker swarm join --token SWMTKN-1-5q21bxnln5799he8fnll8yggp8caxryickc3j9xmaozvgwe97s-e11wyfdcrsbewpx97823ep6xa 172.31.72.142:2377
 
 To get manager token:

docker swarm join-token manager

To get worker token:

docker swarm join-token worker

6、把manager2添加到swarm中。
[root@master1 centos]# docker swarm join-token manager
To add a manager to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-5q21bxnln5799he8fnll8yggp8caxryickc3j9xmaozvgwe97s-44dqddtgbamyu8s292jyuy66k 172.31.72.142:2377
    
7、安装docker swarm UI portainer
 
# mypassword is plaintext here
$ echo -n bosma2018 | docker secret create portainer-pass -
$ docker service create \
  --name portainer \
  --secret portainer-pass \
  --publish 9000:9000 \
  --replicas=1 \
  --constraint 'node.role == manager' \
  --mount type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \
  portainer/portainer \
  --admin-password-file '/run/secrets/portainer-pass' \
  -H unix:///var/run/docker.sock
  
8、利用软链接，修改docker默认的数据路径。
    
    systemctl stop docker
    mv /var/lib/docker /app/
    ln -s /app/docker /var/lib/docker
    systemctl start docker
    systemctl status docker
    
9、在haproxy配置

frontend dashboard
    bind 172.31.72.142:80
    mode tcp
    option tcplog
    default_backend docker-dashboard

backend docker-dashboard
    mode tcp
    option tcplog
    option tcp-check
    balance roundrobin
    default-server inter 10s downinter 5s rise 2 fall 2 slowstart 60s maxconn 250 maxqueue 256 weight 100
    server m1 172.31.72.142:9000 check
    server m2 172.31.82.187:9000 check
    server m3 172.31.61.130:9000 check
    server n1 172.31.76.147:9000 check
    server n2 172.31.80.14:9000 check
    server n3 172.31.56.103:9000 check
