JVM在身份验证酒吧/sub时崩溃

Question

我使用gcp client libraries 在我的Spring-boot应用程序。为了进行身份验证，我正在使用Google_application_credentials路径env变量。它可以与JDK/JRE的其他版本正常工作，但是在下面提到的JDK/JRE

and Repertions：and depertencies：and and Inter everencation：and depentencies：还有其他方法可以对使用路径env Env进行验证以外的其他方法多变的？我可以使用spring.cloud.gcp.credentials.location =文件：{location}与GCP客户端库，而不是ENV变量？

Answer 1

正如@Juraj Martinka提到的那样，基础Google Library io.grpc.netty.shaded 是问题。 Netty似乎不支持高山，因为Netty依赖Glibc，但Alpine没有它，而是Musl Libc。

如果您禁用Netty的本地支持，问题就会消失
或者，如果您使用具有glibc的映像，例如：

azul/zulu-openjdk-alpine：11-jre：基于高山不起作用
azul/zulu-openjdk：11：基于ubuntu，具有glibc-＆gt;使用

-dio.grpc.netty.shaded.io.netty.transport.nonative = true避免使用segfault

示例：

java -jar -Dio.grpc.netty.shaded.io.netty.transport.noNative=true app.jar

另一个解决方法是，使用grpc-netty而不是grpc-netty shaded
