Spring boot Docker-java netty_tcnative的问题

我正在尝试对4个服务进行dockerize，其中一个服务有问题。特别是，该服务是通过spring引导服务实现的，并使用google vision API。在构建图像和启动容器时，一切正常，直到使用GoogleVisionAPI代码为止。然后，在运行容器时出现以下运行时错误：

编辑

通过谷歌搜索，我发现：GRPCJava示例无法在AlpineLinux上运行，因为所需的libnetty tcnative boringssl static依赖于glibc。Alpine正在使用musl libc，应用程序启动将失败，消息与我的类似。

---

我发现尝试构建正确的图像，但对于许多人来说，这似乎是失败的（构建不适用于我的案例）

通过替换Dockerfile的这一行解决了问题：

FROM openjdk:8-jdk-alpine

这一行：

FROM koosiedemoer/netty-tcnative-alpine

我可以在日志中看到缺少依赖文件“libcrypt.so.1”。抑制：java.lang.unsatifiedlinkerror:/tmp/libio_grpc_netty_shaded_netty_tcnative_linux_x86_641095585491871975468.so：加载共享库libcrypt时出错。so.1：没有这样的文件或目录（需要/tmp/libio_grpc_netty_shaded_netty_shaded_netty_tcnative_linux_x86_641095585491871975468.so）你是对的，我只是编辑了这个问题，回答了为什么它不见了

FROM koosiedemoer/netty-tcnative-alpine
