How to limit the resources allocated to a docker container?

Scalability is the most important factor while deploying an application. That is the reason why IT industries have been moving towards containerization.

“Docker is a platform designed to help developers build, share, and run modern applications and helps to containerize your application.”

Sometimes we are having more than one docker container running on the same server. In this case, we should also handle the resource utilization by the containers. Sometimes it may happen that only a single docker container occupies the whole memory or the CPU power of the server and because of this, other containers are not getting the resources to run the applications on it.

This case can be handled in ways: while using docker-compose and while not using docker-compose

Here, we are specifying the maximum limit on memory (RAM) as 1 GB and the number of CPUs as 2.

2. If you are using docker-compose, add the resources with limits in it as follows:

This is how you can limit the resources to a docker container.
