我一直在尝试使AWS CodeBuild的本地缓存正常工作,并且我一生都无法获得最基本的缓存。我的最终目标是缓存Gradle工件,如here所述。
但是由于无法正常工作,我尝试了一个更简单的测试,在该测试中,我尝试使用文件>>> addToInventory(inventory, dragonLoot)
>>> displayInventory(inventory)
Inventory:
45 gold coin
1 rope
1 dagger
1 ruby
Total of number of items: 48
来缓存目录/root/foo
,并在每次构建时增加该文件。我的期望是,如果我彼此之间在几分钟之内运行后续的构建,我将在日志中看到“ 2”,“ 3”等。但是现实是,尽管建立了符号链接,但是下一个构建版本却看不到前一个counter.txt
文件,这对我来说表明有些问题。
谁能确认他们的本地缓存实际上在CodeBuild中工作?我开始怀疑该功能当前是否损坏!还是我完全误解了该怎么办?
buildspec.yml:
counter.txt

答案 0 :(得分:6)
文档尚不清楚,但是AWS CodeBuild Local缓存可以only cache directories(在撰写本文时)。这有点令人困惑,因为AWS CodeBuild buildspec specification allows the path to be individual files or a wildcard,但实际上指定文件会产生错误。
Unable to initialize cache download: only directories can be cached locally: ...
在您的示例中,您使用将缓存指定为
cache:
paths:
- '/root/foo/*'
其中*表示foo内部的所有单个文件和文件夹,但仅缓存文件夹。
指定整个目录应该起作用
cache:
paths:
- /root/foo/
答案 1 :(得分:2)
我一直在尝试使缓存自身能够成功运行,
不是来自任何公开来源,而是一些观察结果:
仅当构建时间超过5分钟时,缓存才可用。
如果新版本成功放置在同一版本主机上,则可以使用缓存。
缓存。缓存可能会根据上一次构建时间保持可用状态,最长为15分钟。
尽管构建时间超过5分钟,但由于将构建放置在不同的构建主机上,缓存可能无法始终正常工作。
此外,在缓存将新版本加速到5分钟以下的情况下,该版本将不会被缓存,从而导致后续未命中。
尽管我相信CodeBuild工程师有充分的理由进行这种设计,但我认为上述限制使得该本地缓存功能的使用受到限制。
