Config maps ideally stores APPLICATION configuration in a plain text format whereas Secrets store sensitive data like password in an encrypted format. Both config maps and secrets can be USED as volume and MOUNTED inside a pod through a pod definition file.

Config map:

kubectl create configmap myconfigmap --from-literal=env=dev

Secret:

echo -N ‘admin’ > ./username.txt echo -n ‘abcd1234’ ./password.txt kubectl create secret generic mysecret --from-file=./username.txt --from-file=./password.txt
