AWS - Auto Scaling

You wrote this snippet to create an Auto Scaling group but it fails:

aws autoscaling create-auto-scaling-group --auto-scaling-group-name my-asg --min-size 2 --max-size 1 --desired-capacity 1 --launch-configuration-name my-launch-config --vpc-zone-identifier subnet-12345

What is the error?

AVPC subnet ID is invalid

BDesiredCapacity cannot be less than MinSize

CLaunch configuration name is missing

DMinSize cannot be greater than MaxSize

Step-by-Step Solution

Solution:

Step 1: Check size parameters
MinSize is set to 2, MaxSize is set to 1, which is invalid because MinSize must be less than or equal to MaxSize.
Step 2: Validate other parameters
DesiredCapacity is 1, which is allowed if between MinSize and MaxSize, but here MinSize > MaxSize causes failure.
Final Answer:
MinSize cannot be greater than MaxSize -> Option D
Quick Check:
MinSize ≤ MaxSize rule violated [OK]

Quick Trick: MinSize must be ≤ MaxSize to create group [OK]

Common Mistakes:

Setting MinSize higher than MaxSize
Ignoring error messages about sizes
Assuming DesiredCapacity fixes size conflicts
