Which feature in Docker allows us to create and run multi container applications?

Docker compose is a tool to define and run multi-container docker applications. With docker compose, you configure all your application's services (containers) in a single yaml file, then spin up all of them with a single command.


Subsequently, one may also ask, can we run multiple apps on one server with Docker?

It's ok to have multiple processes, but to get the most benefit out of Docker, avoid one container being responsible for multiple aspects of your overall application. You can connect multiple containers using user-defined networks and shared volumes. Then you start supervisord , which manages your processes for you.

Subsequently, question is, which Docker command lets us attach to a running container? There is a docker exec command that can be used to connect to a container that is already running. Generically, use docker exec -it <container name> <command> to execute whatever command you specify in the container.

Likewise, people ask, can you run multiple Docker containers?

Yes. You can run multiple containers on one server, and it is not restricted to the number of CPUs. Your command creates and starts exactly 1 container that has access to at most 16 CPUs (and in the 2nd example only precisely CPUs 0-15).

What is Docker compose file used for?

The Compose file provides a way to document and configure all of the application's service dependencies (databases, queues, caches, web service APIs, etc). Using the Compose command line tool you can create and start one or more containers for each dependency with a single command ( docker-compose up ).
