该博客主要介绍了使用Docker部署分布式Minio的详细步骤。首先讲解了创建蜂群，包括主节点初始化、从节点加入及查看蜂群；接着阐述部署分布式Minio，如准备密钥、添加节点标签、准备docker - compose文件和部署stack；最后说明了删除stack和volume的操作。

Docker部署swarm模式的minio

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：

docker node ls

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

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
minio1在master上，minio2在slave001上，minio3和minio4在slave00上

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'

services:
  minio1:
    image: minio/minio:RELEASE.2020-11-19T23-48-16Z

  secret_key:
    external: true

  access_key:
    external: true
    name: minio_access_key

2.4 部属stack

docker stack deploy --compose-file=docker-compose-secrets.yaml minio_stack

三、删除

3.1 删除stack

docker stack rm minio_stack

3.2 删除volume

docker volume prune
