红帽全球峰会2.5.5.13. Cache
集成 registry 会主动缓存数据，以减少对减慢外部资源的调用数量。有两个缓存：
- 用于缓存 Blob 元数据的存储缓存。此缓存没有过期时间，数据会一直存在，直到显式删除为止。
- 应用缓存包含 blob 和存储库之间的关联。此缓存中的数据具有过期时间。
要完全关闭缓存，您需要更改配置：
version: 0.1
log:
level: debug
http:
addr: :5000
storage:
cache:
blobdescriptor: ""
openshift:
version: 1.0
cache:
disabled: true
blobrepositoryttl: 10m
