@tylorC, the echo command from redis:latest image apparently does not have arguments, so it prints everything. This explains the -en /n.
The variables aren’t being printed because you declared the env under spec and, according to kubectl explain, the env should be under containers

#36

thanks for the reply, I will try it again

#37

if anyone has an issue completing this task, refer to this doc and make the necessary changes as per the task details.
Yaml example: Use Pod fields as values for environment variables

@rahul456 please look into it
i believe my task is correct but marked as incorrect due to any validation error

Failure Details:

first ENV ‘GREETING’ value is not ‘Welcome to’

#39

Hi @hjavaid

Its not a validation error, you can see the extra quotes in the logs output.
