Docker: What is the meaning of global service in terms of docker ?

Question

I have one application which is running in a stand alone system. I want to run the same application in a docker container. I also want to know that is only one process that can run in a docker container ?

Answer 1

When we say launch a service globally in docker cluster then it means launch the service in each compute host of cluster.
There is an option which need to mention while launch a service through docker cli.

$docker service create --mode global --name container_name image_name

Hope so my answer will help you somewhat.
