Paketo构建包在更新时失败

Question

我有一个非常简单的Spring应用程序，为Azure构建Docker图像。也许Azure与这个问题无关。映像是使用弹簧启动级插件，使用bootBuildImage任务构建的。

现在，突然之间，如果代码没有变化，构建就会开始失败：

> Task :backend:bootBuildImage FAILED
…
… Invalid response received when loading image "pack.local/builder/uxjmhhddud:latest"

每次运行时，映像的名称都会发生变化，看起来就像一个临时的中间映像，无法读取。

是什么导致了这一失败，如何应对？

编辑:更多日志上下文：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':backend:bootBuildImage'.
> Invalid response received when loading image "pack.local/builder/xojqjhijta:latest"

Answer 1

在排除了Docker守护进程问题或代理等问题之后，我决定可能Paketo构建器的版本只是一个out。事实上，将版本与最后一个已知的好版本联系起来是有效的：

tasks.bootBuildImage {
    // Pin version to known working
    builder = "paketobuildpacks/builder@sha256:855aaa00a7eadca9c6cdba72550889f7c618c2bf1489c29fb9e7e01588665db7"
    …
}

较新的跑步者和基本形象运作良好。
