• 1.安装docker环境,参考其他教程

• 2.初始化docker swarm
  docker swarm init [option]

• 3.创建网关 over-lay
  docker network create -d overlay swarm-overlay

• 4.登录私有docker私服
  sudo docker login -u 'username' -p 'password' registry-vpc.cn-hangzhou.aliyuncs.com

• 5.部署deploy
  docker stack deploy -c docker-stack-deloy.yml --with-registry-auth {stackName}

• 6.其他命令

# 查看服务运行情况
docker service ls

# 输出docker swarm service日志
docker service logs -f --tail=100 {serviceName}

# 查看所有堆栈
docker stack ls 

# 查看stack内容器运行情况
docker stack ps {stackName} 

# 删除指定镜像关联的Exited容器
sudo docker container rm $(sudo docker container ls -a|grep 'registry-vpc.cn-hangzhou.aliyuncs.com/xxxxx'|grep 'Exited'|awk '{print $1}')

# 删除未被容器使用关联指定镜像($GIT_COMMIT 为 jenkins中的session级别的环境变量 )
sudo docker rmi $(sudo docker image ls|grep 'registry-vpc.cn-hangzhou.aliyuncs.com/xxxxx'|grep -v $GIT_COMMIT|awk '{print $3}')

# 横向扩容/收缩
docker service scale {serviceName}=2

• 7.其他 docker-stack-deloy.yml 文件参考 (endpoint_mode 默认为 vip 模式)
