Hi there @mgalland,

You would just need to adjust the -p argument and change the first part from 8787 to the new port that you would like to use.

For example:

• Starting the first container on port 8787:

docker run --rm --name rstudio-1 -e PASSWORD=mypwd -p 8787:8787 scienceparkstudygroup/master-gls:openr-latest

• Starting the second container on port 8788:

docker run --rm --name rstudio-2 -e PASSWORD=mypwd -p 8788:8787 scienceparkstudygroup/master-gls:openr-latest

Note: Make sure to use different names as well otherwise it would not work.

You could also add Nginx as a reverse proxy to the set up:

Here’s a quick video demo on how to do the above:

Hope that this helps!

Bobby
