在 Cloud Run 上运行 Firebase 函数代码

如何解决在 Cloud Run 上运行 Firebase 函数代码

我正在使用用 TypeScript 编写的 Firebase 函数，并希望尝试在 Cloud Run 上以尽可能少的更改运行代码。到目前为止，我发现的最佳解决方案是使用 buildpacks 将 Firebase 函数包装在 Docker 容器中，然后将其部署到 Cloud Run。它们支持 Google Cloud Functions，所以理论上应该是可能的。

我尝试按照演示 here 进行操作，但没有成功。生成 buildpack 后，它出现 command not found: firebase 错误，它来自启动脚本 (firebase serve --only functions)。我尝试将其更改为 npx firebase...，但仍然出现相同的错误。

有什么解决这个问题的建议吗？

构建命令：pack build --builder=gcr.io/buildpacks/builder buildpack-my-functions 堆栈跟踪：

解决方法

您的 buildpack 进程使用 nodejs 检测代码。并使用 Node JS 运行时映像来运行您的代码。效果很好！！

但不适用于您的用例。您需要自定义运行时映像以使用安装了 firebase 的映像。为此，您可以使用参数 --run-image 并使用这样的命令

pack build --builder=gcr.io/buildpacks/builder --run-image=<Firebase image>  buildpack-my-functions

我不是 firebase 的用户，我查找了 firebase 的运行时映像，除了对 how to build yourselves your runtime image 的描述外，我什么也没找到。

Buildpack 很棒，原理在这里，但不是那么好用（对于 firebase）...
