SpringBoot 对象存储 MinIO的详细过程

## 国外资源，龟速下载
## /usr/local/minio 存储目录；--console-address 是 UI 界面的端口
wget https://dl.min.io/server/minio/release/linux-amd64/minio 
chmod +x minio
MINIO_ROOT_USER=admin MINIO_ROOT_PASSWORD=admin123 ./minio server /usr/local/minio --console-address ":9001" 

cd /usr/local/mkdir minio

version: '3'
services:
  minio:
    image: minio/minio
    container_name: myminio
    ports:
      - "9001:9000"
    volumes:
      - /usr/local/minio/data:/data
      - /usr/local/minio/config:/root/.minio
    environment:
      MINIO_ROOT_USER: "admin"
      MINIO_ROOT_PASSWORD: "admin123"
    command: server /data
    restart: always

# 后台启动
docker-compose up -d
# docker-compose logs  yml里面的服务id     # 查看容器输出日志
docker-compose logs minio
