docker 拉去minio镜像

docker run -p 9000:9000 -p 9001:9001 minio/minio server /data
    \--console-address ":9001"

docker 启动镜像

docker run -d `
  -p 9000:9000 `
  -p 9001:9001 `
  --name minio `
  -v D:\minio-data:/data `
  -e "MINIO_ROOT_USER=minioadmin" `
  -e "MINIO_ROOT_PASSWORD=minioadmin" `
  minio/minio server /data --console-address ":9001"
