Running multiple instances of the same docker module at the same time

Docker Desktop for Mac

Hi,

I would like to run multiple instances of the same docker module at the same time. Is this possible?

Cheers,

Steve

What do you mean by “module”?

You can run multiple containers using the same image:

# launches a container that will sleep in the background for 5 minutes:
docker run --rm -ti ubuntu sleep 300 &

# launches a second container using the same image:
docker run --rm -ti ubuntu sleep 300 &

To verify this, list the running containers with

# list all running containers with the images they were launched from
docker ps

CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
