Docker

Set Docker Memory and CPU Limits

Docker best practice:

Limit CPU and memory for your containers to prevent crippling the rest of the containers on the machine.

Examples:

# using docker run
$ docker run --cpus=2 -m 512m nginx


# using docker-compose
version: "3.9"
services:
  redis:
    image: redis:alpine
    deploy:
      resources:
        limits:
          cpus: 2
          memory: 512M
        reservations:
          cpus: 1
          memory: 256M
