Question

How can I configure Docker to use a specific number of CPU cores for a container?

You would configure the Docker container with its CPU resources in order to improve the performance and to avoid contention with other containers on the same host. This question looks into the mechanism of how one can set the limits for the number of CPU cores that a Docker container may use, what Docker commands, options, or configuration files you should modify in order to handle the allocation of CPU to containers. This is supposed to determine how you'd tune your containers' performance and resource usage on a multi-core system.
