Docker - Resource Management

What will happen if you run this command?
docker run --memory=100m --memory-reservation=150m myapp

AContainer will start with a hard limit of 100MB and soft limit of 150MB.

BDocker will throw an error because reservation cannot be higher than limit.

CContainer will ignore memory-reservation and use 100MB limit only.

DContainer will have a hard limit of 150MB and soft limit of 100MB.

Step-by-Step Solution

Solution:

Step 1: Understand relationship between limits
Memory reservation must be less than or equal to memory limit.
Step 2: Analyze given values
Reservation is 150m which is greater than limit 100m, invalid configuration.
Final Answer:
Docker will throw an error because reservation cannot be higher than limit. -> Option B
Quick Check:
Reservation ≤ Limit rule = error if violated [OK]

Quick Trick: Reservation must not exceed memory limit [OK]
