hi @nithyaks, as per question, your image should be ‘httpd’ instead of ‘redis’

[nithyaks]

@rahul456

My Task failed. But i think is correct. Please Advise

[rahul456]

@chawki, sorry for the issue, this is marked pending for you, please give it an another try.

[chawki]

Thanks for your prompt response.

I give it another try. It’s failed again but now because i misspelled the Word Devops instaed of “DevOps”

[Tej-Singh-Rana]

Hello, @chawki
Can you please share in the “Review” Section?

[tylorC]

my templet is below and the out looks wrong, what I did wrong?

[francilio]

@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

[tylorC]

thanks for the reply, I will try it again

Hi @hjavaid

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