Docker - Resource Management
What is a likely consequence of not setting CPU limits on a Docker container?
AThe container will automatically restart on failure
BThe container will not start
CThe container may use excessive CPU, slowing down other processes
DThe container will run with no network access
Step-by-Step Solution
Solution:

  1. Step 1: Understand CPU limits effect

    Without CPU limits, a container can consume all CPU resources available on the host.

  2. Step 2: Identify impact on system

    This can slow down other containers and processes sharing the host.

  3. Final Answer:

    The container may use excessive CPU, slowing down other processes -> Option C

  4. Quick Check:

    CPU limits prevent resource hogging = D [OK]
Quick Trick: No CPU limit means container can hog CPU [OK]
Common Mistakes:
  • Assuming container won't start without limits
  • Confusing CPU limits with memory limits
  • Thinking limits affect networking
