MinIO

安装MinIo

# 先创建minio 文件存放的位置
mkdir -p /opt/docker/minio/data# 启动并指定端口
docker run \-p 9000:9000 \-p 5001:5001 \--name minio \-v /opt/docker/minio/data:/data \-e "MINIO_ROOT_USER=minioadmin" \-e "MINIO_ROOT_PASSWORD=minioadmin" \-d minio/minio server /data --console-address ":5001"# 设置为和 docker 绑定启动,docker 启动则 minio 就启动
docker update --restart=always
