how to create a selenium/standalone-chrome image with changeable port (the 4444)

Question

I'm was wondering how can I pass a different port number as argument when I'm running the selenium container instead of the default port(4444)

Usually I'm using:

docker run --shm-size=2G -d --net=host -e TZ=UTC -e SCREEN_WIDTH=1920 -e SCREEN_HEIGHT=1080  selenium/standalone-chrome:3.7.0

Is it possible to do so with the current selenium image or do I need to build a selenium image of my own and if so how to create that kind of image?

You can bind port with -p

docker run -d -p 4444:4444 --name selenium-hub selenium/hub:3.8.1-aluminum

But if you want change the port inside container I think you must modify sources of image.

Not sure if this works with your docker image, it might help if you try to build your own image.

Open entrypoint.sh and edit java ${JAVA_OPTS} -jar /opt/selenium/selenium-server-standalone.jar -role hub -port (custom port no.)

Then in dockerfile change EXPOES (custom port) Then build docker again
