Creating a Secret Using kubectl create secret

From File

Declare the secret content in one (or more) file(s) on the local filesystem. When the secret is exposed to a pod, the content will be available as volume files with the same name.

echo -n "test-user" > ./username.txt
echo -p "test-password" > ./password.txt

kubectl create secret generic username-and-password --from-file=./username.txt --from-file=./password.txt

This will create the following secret:

Name:         username-and-password
Namespace:    test
Labels:       <none>
Annotations:  <none>
