Running docker image with argument

Question

I am working with spring-boot along with docker images.

I am running my springboot application directly from IntelliJ name as runtime with some of argument like below

-DCONFIG_DIR=D:\baseapimanager\runtime\config

I am able to run it successfully.

But by creating a docker image and running that image, it's not able to run. As i am not aware about how to pass argument while running docker image.

Here i had shared my Docker file contents as well.

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ADD target/docker-runtime.jar docker-runtime.jar
EXPOSE 8091
ENTRYPOINT ["java","-jar","docker-runtime.jar"]

And running below docker command i am trying to create image file for same.

docker build -f Dockerfile -t docker-runtime .

After this executing below command to run this generated image file.

docker run -p 8091:8091 docker-runtime

Without passing that argument and commenting business with that argument, it's working perfectly fine.

Any help will be appreciated.

Answer 1

I had made below changes in my Docker file.

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ADD target/docker-runtime.jar docker-runtime.jar
EXPOSE 8091
ENTRYPOINT ["java","-jar","-DCONFIG_DIR=/shareddata","docker-runtime.jar"]

And while running an image i had bind that address using below command , and it's working fine.

docker run -p 8091:8091 --mount type=bind,source=/c/Users/lenovo/data,target=/shareddata docker-runtime

This had resolved my problem.
