MinIO
MinIO 是一个高性能、兼容 S3 的对象存储，主要用于各种云原生应用、数据备份、归档等通用场景。提供身份验证，访问控制，加密等方式保护存储数据的安全。
MinIO Docker
$ docker run -d \--name minio \-p 9900:9000 \-p 9901:9001 \-v ~/data/docker/minio/data:/data \-v ~/data/docker/minio/config:/root/.minio \-e MINIO_ROOT_USER=tester \-e MINIO_ROOT_PASSWORD=12345678 \minio/minio server /data --console-address ":9001"

概念
-
bucket: MinIO使用bucket来组织对象。bucket类似于文件系统中的文件夹或目录，其中每个bucket可以容纳任意数量的对象。
-
access key: 继承了显式附加到父用户的策略，以及附加到其父用户所属的每个组的策略。
创建 bucket
上传对象 （任何文件/文件夹）
- 上传一张图片
创建访问密钥
验证
以下使用Python验证
- 检查存储桶是否存在
- 上传文件到存储桶
- 列出存储桶中的所有对象
- 下载文件从存储桶
- 删除存储桶中的对象
from minio import Minio
from minio.error import S3Erroraccess_key = "jsbZVomx7aYfs8ZkWcpj"
secrets_key = "alVeNp8ZbpdWIzZeEGfLvn6UliX0UBWDRh5OiQwy"# 初始化 MinIO 客户端
minio_client = Minio(# MinIO 服务器地址 9900 而不是 9901，不要加 http/https前缀endpoint="192.168.56.101:9900", # 访问密钥access_key=f"{access_key}",# 安全密钥secret_key=f"{secrets_key}",# 如果使用 HTTPS，设置为 Truesecure=False
)bucket_name = "bucket1"
object_name = "example"
file_path = "../../data/file.txt"

输出
Bucket 'bucket1' already exists.
File '../../data/file.txt' uploaded as 'example' to bucket 'bucket1'.
Objects in bucket 'bucket1':
example
kafka.png
File 'example' downloaded from bucket 'bucket1' to '../../data/file_download.txt'.
可能遇到的错误
- 访问密钥及安全密钥没配置正确
S3 operation failed; code: InvalidAccessKeyId, message: The Access Key Id you provided does not exist in our records., resource: /bucket1, request_id: 182E8D3B83F823D5, host_id: dd9025bab4ad464b049177c95eb6ebf374d3b3fd1af9251148b658df7ac2e3e8, bucket_name: bucket1
- endpoint 配置错误
