Docker部署swarm模式的minio

• • 一、创建蜂群
  • • 1.1 主节点上初始化
    • 1.2 从节点加入蜂群
    • 1.3 查看蜂群
  • 二、部属分布式的minio
  • • 2.1 准备密钥
    • 2.2 给分群节点添加标签
    • 2.3 准备docker-compose的文件
    • 2.4 部属stack
  • 三、删除
  • • 3.1 删除stack
    • 3.2 删除volume

一、创建蜂群

1.1 主节点上初始化

master上执行：

docker swarm init --advertise-addr 192.168.1.100
           

1.2 从节点加入蜂群

在slave001和slave002上执行：

docker swarm join --token SWMTKN-1-3nd71k9vkufr27loqf74offrjvqyezozizj3poq10jf3hdefvd-a3q6c8u227f3rcfnkomdq5pql 192.168.1.100:2377
           

1.3 查看蜂群

在master上查看蜂群：

二、部属分布式的minio

2.1 准备密钥

echo "minioadmin" | docker secret create minio_access_key -
echo "minioadmin" | docker secret create minio_secret_key -
           

2.2 给分群节点添加标签

docker node update --label-add minio1=true nu93s16h3lwt1et8606hy2woi
docker node update --label-add minio2=true yqiyrmyjptx91owxqs94qsfcw
docker node update --label-add minio3=true usfo19iz0ehtle7bvzfc9z9hh
docker node update --label-add minio4=true usfo19iz0ehtle7bvzfc9z9hh
           

1. 必须至少是4个节点。因为采用的是Erasure Code（纠删码） 的方式实现数据恢复运算
2. minio1在master上，minio2在slave001上，minio3和minio4在slave00上
3. 纠删码的一些资料：https://zhuanlan.zhihu.com/p/106096265?utm_source=wechat_session

2.3 准备docker-compose的文件

新建一个文件

docker-compose-secrets.yaml

vi docker-compose-secrets.yaml
           

文件内容如下：

version: '3.7'
