在启动minio的时候，我们会声明一个pv，其中定义了minio最终文件的存储方式和路径 minio/k8s/standalone/pv.yaml
volumeMode: FilesystemhostPath:path: /Users/xiazemin/source/k8s_learn/minio/k8s/standalone/minio/
进入到/Users/xiazemin/source/k8s_learn/minio/k8s/standalone/minio/这个目录，我们可以看到里面的有一个隐藏目录：
.minio.sys
进入到这个隐藏目录，里面的文件如下：
bucketsconfigformat.jsonmultiparttmp
假设我们创建一个buckey
mymusic
然后上传一个文件
test.tar
1，我们去buckets里面看下文件列表如下
.bloomcycle.bin.minio.sys.tracker.bin.usage-cache.bin.usage.jsonmymusic
进入到mymusic目录我们就看到了我们上传的文件test.tar
.metadata.bin.usage-cache.bintest.tar
接着看下.usage.json文件的详细类容
{"lastUpdate": "2021-11-21T06:22:24.902605427Z","objectsCount": 1,"objectsTotalSize": 9099,"objectsReplicationInfo": null,"bucketsCount": 1,"bucketsUsageInfo": {"mymusic": {"size": 9099,"objectsPendingReplicationTotalSize": 0,"objectsFailedReplicationTotalSize": 0,"objectsReplicatedTotalSize": 0,"objectsPendingReplicationCount": 0,"objectsFailedReplicationCount": 0,"objectsCount": 1,"objectsSizesHistogram": {"BETWEEN_1024_B_AND_1_MB": 1,"BETWEEN_10_MB_AND_64_MB": 0,"BETWEEN_128_MB_AND_512_MB": 0,"BETWEEN_1_MB_AND_10_MB": 0,"BETWEEN_64_MB_AND_128_MB": 0,"GREATER_THAN_512_MB": 0,"LESS_THAN_1024_B": 0},"objectReplicaTotalSize": 0,"objectsReplicationInfo": { }}},"bucketsSizes": null}
里面定义了文件数量和分桶的信息，以及每个桶内的统计信息。
2，config 目录下就一个文件和一个目录
config.jsoniam
先看下config.json的详细内容：

里面定义了minio的全局配置，比如消息通知，有多种方式，redis，kafka，postgres，nsq，webhook等等，同时也定义了认证方式，审计，日志，https 等相关内容，比如初始化的用户名和密码：
"credentials": {"_": [{"key": "access_key","value": "minioadmin"},{"key": "secret_key","value": "minioadmin"}]},
在iam里面只有一个文件format.json，内容如下：
{"version":1}
3，外层的format.json文件
format.json{"version":"1","format":"fs","id":"bd78d817-8f16-4589-a8fd-e7db8569033e","fs":{"version":"2"}}
定义了format是fs
4，multipart，由于我们没有分片上传过文件，所以multipart目录里面是空的。
5，最后看下tmp目录，里面是一系列目录
tmp1eb28e69-63c4-4c14-b02b-0b0c5452acbb1fe4efd1-aa6a-4403-bcf1-080894be4b089aca98bc-0f13-44ef-b5d6-6f783bcda0a3
每次上传文件的时候都会创建一个目录，目录里面内容是空的。因为文件上传完毕后都会mv到指定bucket的目录。
