开源minio-AWS-S3存储的部署及java操作

简介

MinIO 是在 GNU Affero 通用公共许可证 v3.0 下发布的高性能对象存储。它是与 Amazon S3 云存储服务兼容的 API。使用 MinIO 为机器学习、分析和应用程序数据工作负载构建高性能基础架构。

搭建mini

MinIO 需要一个持久卷来存储配置和应用程序数据。但是，出于测试目的，您可以通过简单地传递一个目录（/data在下面的示例中）来启动 MinIO 。该目录是在容器启动时在容器文件系统中创建的。但是容器退出后所有的数据都丢失了。如果打算持久化，进行挂载即可。

docker run \
  -p 9000:9000 \
  -p 9001:9001 \
  -e "MINIO_ROOT_USER=LIUYUNSHENG" \
  -e "MINIO_ROOT_PASSWORD=LIUYUNSHENGKEY" \
  minio/minio server /data --console-address ":9001"

搭建持久化的

docker run --restart always --privileged=true -d -p 9000:9000 -p 9001:9001\
-v /home/lys/minio/miniodata:/data:rw -v /home/lys/minio/minioconfig:/root/.minio:rw \
-v /etc/localtime:/etc/localtime:ro \
minio/minio server /data \
--console-address ":9001"
