I want to know the exact difference between the docker and docker-compose.
And In docker-compose.yml file we have to set
- redis ( This is an existing imageName, am i right…? ) .
My question how the docker-compose linked / identified this image into an application , how they communicate each other …? How they transferred or shared their files …?
Have a lot of confusions / queries in docker-compose . Kindly clear me the understandings of those .
