Hello developers and DevOps enthusiasts, welcome to the new part of my Docker Advance Series. In this part, we are going to understand what is CPU quota and how to effectively use it in Docker. Let’s dive deep into the topic.

What is CPU Quota?
A CPU Quota is a limit on the amount of CPU time a process or container can use within a given period. It is commonly used in Linux cgroups (control groups) and container runtimes like Docker and Kubernetes to allocate CPU resources efficiently.
What is CPU time? — CPU time is a time that CPU spends on executing a thread or a process.
Based on following example:
CPU Share = CPU Quota / CPU Period
50% = 50ms / 100ms
CPU Share will be 50% which means a process will consume 50% of single CPU core.
