Vert.x Kotlin 项目部署在 Docker

Question

我有一个用 Kotlin 的 vert.x 框架编写的项目。我构建了 jar 文件，我想通过 Docker 运行这个 jar。但是 docker 找不到我的主 Verticle 文件。

Docker文件：

FROM vertx/vertx3

ENV VERTICLE_NAME OpenApiRoutingVerticle.kt
ENV VERTICLE_FILE build/libs/vertx-kotlin-project-1.0-SNAPSHOT.jar
ENV VERTICLE_HOME /usr/verticles
EXPOSE 8080
COPY  $VERTICLE_FILE $VERTICLE_HOME/
WORKDIR $VERTICLE_HOME
ENTRYPOINT ["sh", "-c"]
CMD ["exec vertx run $VERTICLE_NAME -cp $VERTICLE_HOME/* $VERTX_OPTIONS"]

我的主 Verticle 的路径

 com.mycompany.department.OpenApiRoutingVerticle

PS 错误是：

Answer 1

请尝试替换行 ENV VERTICLE_NAME OpenApiRoutingVerticle.kt ENV VERTICLE_NAME com.mycompany.department.OpenApiRoutingVerticle

kotlin 文件被编译为一个 .class 文件，只要您提供 class 路径位置，就应该选择该文件。
