jenkins - How to pass docker container arguments when running the image in a Jenkinsfile -

i have dockerfile ends with

entrypoint ["node", "index.js"] cmd ["--help"] 

the index.js can take couple different arguments , need expose port container if run manually like:

docker run -p 3000:3000 my_container:latest --arg1 somearg --arg2 anotherarg 

how do in jenkinsfile? test communicate container needs running before run test. use withrun() running before test runs don't see how specify --arg1 somearg --arg2 anotherarg

stage('testmicroservice') {     //     // how specify '--arg1 somearg --arg2 anotherarg'?     //     docker.image("my_container:latest").withrun('-p 3000:3000') {         sh 'npm run test-microservice'     } } 

you can use second argument of withrun

.withrun('-p 3000:3000', '--arg1 somearg --arg2 anotherarg')
