Kubernetes - ConfigMaps

You attempt to create a ConfigMap using this command:

kubectl create configmap mymap --from-literal=key1 value1

but it fails. What is the cause of the error?

AThe syntax is incorrect; the key-value pair must be joined with '=' without spaces.

BThe ConfigMap name 'mymap' is invalid and must be in uppercase.

CThe command requires the --from-file option instead of --from-literal.

DThe key 'key1' cannot be used as it is a reserved keyword.

Step-by-Step Solution

Solution:

Step 1: Identify the command syntax
The command uses --from-literal=key1 value1 which separates key and value by a space.
Step 2: Correct syntax for literals
The correct syntax requires the key and value to be joined by an equals sign with no spaces, like --from-literal=key1=value1.
Final Answer:
The syntax is incorrect; the key-value pair must be joined with '=' without spaces. -> Option A
Quick Check:
Check for '=' between key and value [OK]

Quick Trick: Use '=' to join key and value in --from-literal [OK]
