Kubernetes - ConfigMaps

You want to create a ConfigMap named app-settings with these key-value pairs:
env=production, debug=false, and timeout=0. You run:

kubectl create configmap app-settings --from-literal=env=production --from-literal=debug=false --from-literal=timeout=0

Later, you mount this ConfigMap as environment variables in a Pod. What should you be careful about regarding the timeout value?

AThe timeout key will be converted to boolean false automatically

BThe value '0' will be ignored because it is falsy

CThe value '0' is a string and will be passed as "0", not as a number zero

DThe ConfigMap will fail to create because '0' is invalid

Step-by-Step Solution

Solution:

Step 1: Understand ConfigMap data types
ConfigMaps store all values as strings, so '0' is stored as the string "0".
Step 2: Effect when used as environment variable
When mounted as environment variables, the value will be "0" (string), not a numeric zero or boolean false.
Final Answer:
The value '0' is a string and will be passed as "0", not as a number zero -> Option C
Quick Check:
ConfigMap values are strings, even '0' [OK]

Quick Trick: ConfigMap values are always strings, watch for '0' as string [OK]
