我有一个连接到 MySQL 数据库的 quarkus 应用程序。
我使用生成的 Dockerfile.jvm 来构建我的 docker 镜像。而且我在本地桌面上运行这个图像没有问题。
但是，当我想在我的 vm 上运行相同的图像时，我有以下堆栈跟踪:

最佳答案
我通过以下内容替换原始 Dockerfile.jvm 内容解决了我的问题:
FROM openjdk:11-jdk-slim
COPY target/lib/* lib/
COPY target/*.jar app.jar
ENTRYPOINT ["java","-jar","/app.jar"]
关于docker - Quarkus Docker JVM SSL 问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/64729717/
