第一步 查镜像
docker search minio
第二步 拉镜像
docker pull minio/minio
第三步 启动容器
docker run -p 9000:9000 --name minio -d --restart=always -e “MINIO_ACCESS_KEY=admin” -e “MINIO_SECRET_KEY=admin123456” -v /home/data:/data -v /home/config:/root/.minio minio/minio server /data
第四步 登录界面
http//:ip+9000
ACCESS_KEY:damin
SECRET_KEY:admin123456
