Damage to Vert.x-based application on docker container

I am trying to run a Vert.x Java application on a Docker container. My application runs several vertices that it initiates within itself. I put the jar file in a folder and created a Docker file with the following contents:

FROM vertx/vertx3
ENV VERTICLE_FILE Medical-1.0-SNAPSHOT.jar 
ENV VERTICLE_HOME /performit/web/vertx/verticles/
COPY $VERTICLE_FILE $VERTICLE_HOME/  
WORKDIR $VERTICLE_HOME
ENTRYPOINT ["sh", "-c"]
EXPOSE 8080
CMD ["java -jar $VERTICLE_FILE"]
USER daemon

I create an image using the command

$ sudo docker build -t medical-main .

Then I try to create a container with the following line:

sudo docker run --name medical-main -p 8080:8080 -d  medical-main

This fails and the log shows the following:

java.lang.IllegalStateException: Failed to create cache dir
at io.vertx.core.impl.FileResolver.setupCacheDir(FileResolver.java:257)
at io.vertx.core.impl.FileResolver.<init>(FileResolver.java:79)
at io.vertx.core.impl.VertxImpl.<init>(VertxImpl.java:138)

at io.vertx.core.impl.VertxFactoryImpl.vertx(VertxFactoryImpl.java:34)
at io.vertx.core.Vertx.vertx(Vertx.java:79)

What am I missing?
