dockerfile - docker run pass arguments to entrypoint

Question

I am able to pass the environment variables using -e option. But i am not sure how to pass command line arguments to the jar in entrypoint using the docker run command.

Dockerfile

FROM openjdk
ADD . /dir
WORKDIR /dir
COPY ./test-1.0.1.jar /dir/test-1.0.1.jar
ENTRYPOINT java -jar /dir/test-1.0.1.jar

test.sh

#! /bin/bash -l

export AWS_ACCESS_KEY_ID=$(aws configure get aws_access_key_id)
export AWS_SECRET_ACCESS_KEY=$(aws configure get aws_secret_access_key)

$value=7

docker run -e AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY  -i -t testjava  $value

Answer 1

Use ENTRYPOINT in its exec form

ENTRYPOINT ["java", "-jar", "/dir/test-1.0.1.jar"]

then when you run docker run -it testjava $value, $value will be "appended" after your entrypoint, just like java -jar /dir/test-1.0.1.jar $value
