Vert.x project in Kotlin deploy in Docker

I have a project written in vert.x framework in Kotlin. I build jar file, and I want to run this jar through Docker. But docker can't find my main Verticle file.

Dockerfile: 

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"]

Path to my main verticle

 com.mycompany.department.OpenApiRoutingVerticle

PS the error is:

java.lang.IllegalStateException: Cannot find verticle script: OpenApiRoutingVerticle.kt on classpath

Solution

  • Please try to replace the line ENV VERTICLE_NAME OpenApiRoutingVerticle.kt with ENV VERTICLE_NAME com.mycompany.department.OpenApiRoutingVerticle

    The kotlin file is compiled to a .class file which should be picked up as long as you provide the classpath location.
