OpenTelemetry Operator - 无法注入自动仪器库

Question

我们计划使用开放遥测作为我们所有应用程序的标准，并且我们已经安装了 opentelemetry-operator 的 Kubernetes 集群之一。otl 收集器和仪器运行良好。当我们将注释（instrumentation.opentelemetry.io/inject-dotnet: opentelemetry-operator-system/my-instrumentation）添加到其中一个.Net部署时，它无法注入库并在日志中显示如下。我们正在使用非 root 用户运行所有部署/pod。请帮助我如何解决它。

Answer 1

这是因为权限问题，您可能已经在 yaml 文件中定义了runasnonroot，这会阻止从 init-container 到您的应用程序容器的 cp 操作。即使您配置了runasuser，您仍然遇到问题。
