Hi @rahul456 @Inderpreet @kodekloud-support3

My task Print Environment Variables failed with the below error.

Task Status - Failed
command ‘echo’ is not used

Please check the below output as the kubectl logs shows the correct output using echo.

thor@jump_host ~$ kubectl get pods
NAME                    READY   STATUS      RESTARTS   AGE
print-envars-greeting   0/1     Completed   0          25s

thor@jump_host ~$ kubectl logs -f print-envars-greeting
Welcome to Stratos Datacenter

Manifest file also has echo command and related arguments configured as requested in task.

command: ["/bin/echo"]
args: ["$(GREETING) $(COMPANY) $(GROUP)"]

Please check and update. Thank you!

Print Environment Variables Aug 18, 2020 3:00:29 PM Aug 26, 2020 3:00:29 PM

This is a task assigned to me 1hr ago which I completed immediately but failed. The validation seems to be incorrect, therefore I requested you to recheck.

#9

@kleansoul, this is marked pending for you, please give it an another try.

#10

After providing all the evidence of the task, I was hoping you would have marked success.

Anyways I again attempted with the same solution and now its successful. Thank you for fixing the issue. :+1:

#11

Thank you so much @rahul456

@rahul456 @mmumshad , HI I feel there are couple of issues with below line:
echo -en ‘/n’

this is how its getting printed:
kubectl logs envars-fieldref -n fieldref-namespace
-en /n
node01
envars-fieldref
fieldref-namespace
10.44.0.1
default

As you can see, getting “-en /n” string in the output

#13

If I just keep echo ‘\n’; in the args, we get correct new line character in the output:

thor@jump_host ~$ kubectl logs envars-fieldref -n fieldref-namespace

node01
envars-fieldref
fieldref-namespace
10.44.0.1
default

node01
envars-fieldref
fieldref-namespace
10.44.0.1
default
