调试构建

请参考这些故障排除提示，了解如何排查 IBM Cloud® Code Engine 构建和运行过程中的问题。

无论您是在控制台还是 CLI 中运行构建，请使用 CLI 对构建问题进行故障诊断。

运行 ibmcloud ce buildrun get --name BUILDRUN_NAME 命令以显示构建运行的详细信息。
查看命令输出中的 Reason。

当构建未按预期进行时，查看日志和系统事件可提供有助于您调试问题的信息。

要考虑的构建限制

每个项目可以具有的最大构建配置数为 100。在需要除去或清除旧的构建运行之前，每个项目总共限制为 100 个构建运行。

有关包括内存和 CPU 在内的构建限制的更多信息，请参阅 Code Engine的限制和配额。

通过 CLI，您可以使用 ibmcloud ce project get 命令来显示有关限制和当前使用情况的信息。例如：

ibmcloud ce project get --name myproject

示例输出

获取我的构建的日志

日志可帮助您在运行构建时对问题进行故障诊断。您可以使用 CLI 或控制台查看构建的日志。

从控制台获取我的构建的日志

您可以从控制台显示特定构建运行实例的日志。

转至 Code Engine 仪表板。
选择项目 (或创建一个)。
在项目页面中，单击 映像构建。
从 映像构建 选项卡中，单击映像构建的名称以打开已定义构建的构建页面，或者创建构建。
从已定义构建的构建页面中，单击 构建运行 部分中构建运行实例的名称。您可能需要单击 提交构建 以创建构建运行。
从构建运行实例页面，您可以查看构建日志信息。展开特定构建步骤以获取详细的日志记录信息。

有关更多信息，请参阅从控制台查看构建日志。

使用 CLI 获取构建的日志

使用 ibmcloud ce buildrun logs 命令可显示有关构建运行的日志。使用此命令可根据构建运行的名称显示构建运行的所有实例的日志。

要查看 mybuildrun 构建运行的所有实例的日志，请使用 --name 选项指定构建运行的名称; 例如，

ibmcloud ce buildrun logs --name mybuildrun

示例输出

Getting build run 'mybuildrun'...
Getting instances of build run 'mybuildrun'...
Getting logs for build run 'mybuildrun'...
OK

获取我的构建的系统事件信息

系统事件信息可帮助您在运行构建时对问题进行故障诊断。您可以使用 CLI 查看构建的系统事件信息。

使用 ibmcloud ce buildrun list 命令列出项目中的所有构建运行; 例如，
```
ibmcloud ce buildrun list  
```

使用 ibmcloud ce buildrun get 命令来获取构建运行的详细信息，例如，

ibmcloud ce buildrun get --name mybuildrun

示例输出

Getting build run 'mybuildrun'...
Run 'ibmcloud ce buildrun events -n mybuildrun' to get the system events of the build run.
Run 'ibmcloud ce buildrun logs -f -n mybuildrun' to follow the logs of the build run.
OK

如果需要有关构建运行的更多细颗粒度详细信息，请将 --o yaml 选项与 buildrun get 命令配合使用; 例如，ibmcloud ce buildrun get --name myapp --o yaml。此选项有助于在 CLI 中显示有关构建运行的更多详细信息。

显示本次构建运行的系统事件。使用 ibmcloud ce buildrun events 命令; 例如，

ibmcloud ce buildrun events --name mybuildrun

示例输出

Getting build run 'mybuildrun'...
Getting instances of build run 'mybuildrun'...
Getting events for build run 'mybuildrun'...
