How to run multiple containers of the same image and expose different ports?
Dear community,
I have built a droplet with Ubuntu 18.04 and Docker CE edition. For teaching purposes, I want to run 18 times the same container based on a Docker image hosted on DockerHub: https://hub.docker.com/repository/docker/scienceparkstudygroup/master-gls
When I run one container and expose it on the 8787 port, everything runs smoothly and I can access the RStudio instance at my droplet IP address + :8787.
docker run --rm --name rstudio -e PASSWORD=mypwd -p 8787:8787 scienceparkstudygroup/master-gls:openr-latest
My problem is to create multiple instances of the same container but expose it to different ports. I have tried Docker-compose but no success so far.
Any idea?
In advance thank you
Marc
