Docker Hands-On Lab — Container Management & Resource Control

Completed a practical Docker lab covering real-world container management and resource control scenarios.

Key highlights:

Pulled and ran nginx:alpine image in background mode with custom container naming

Deployed an Apache container with strict resource limits (70MB memory, 1 CPU core)

Explored and analyzed cgroups paths for memory limit verification

Demonstrated OOM (Out of Memory) Killer behavior by running a memory-limited Alpine container and proving kernel intervention when limits are exceeded

Configured containers with no swap memory to test hard memory boundaries
