Implementing Resource Control in Docker
Explore how to implement resource control in Docker by setting memory limits and CPU usage for containers. Understand using the --memory, --memory-reservation, and --cpus flags, and managing resource constraints in Docker Compose. This lesson helps you ensure containers use system resources efficiently and prevents resource conflicts.
We'll cover the following...
Implementing resource control in Docker, including resource reservation and CPU limiting, is essential to ensure that our containers run efficiently and don’t monopolize system resources. Resource control in Docker involves setting memory limits for containers to approximate reservation and restricting CPU usage using the --cpus flag. In Docker Compose, resource constraints like memory and CPU limits can be specified in service definitions, with a base docker-compose.yml file and an override file.
Resource reservation
Docker also allows us to reserve a minimum memory for a container using the --memory-reservation flag. This ensures that the container gets at least the specified ...
