Basavraj Nilkanthe:
While practising lighting lab 1 , while attempting last questions , there was question about requests 2 cpu , i have used kubectl set resources deploy redis --requests=cpu=2, it is complaining with below error message and saying insufficent resource… Thats why I couldnt able to complete LL-1 successfully… Any Idea guys what was missed here?
Rajesh Sinha:
As per error, don’t have enough cpu resources available on nodes
Basavraj Nilkanthe:
yes it seems
Basavraj Nilkanthe:
just wanted to confir Rajesh if we can just requests for cpu if we dont defined limits?
Basavraj Nilkanthe:
is that limits definitation mandatory for requests
Basavraj Nilkanthe:
I tried both but still no luck
Basavraj Nilkanthe:
it seems to be resource issue
Basavraj Nilkanthe:
then this lab need to updated
Basavraj Nilkanthe:
kubectl set resources deploy redis --requests=cpu=2 --limits=cpu=2

Kicky:
@Basavraj Nilkanthe,the question says to request for “0.2” cpu. Not 2 cpu
Rajesh Sinha:
As per question, you can use 200m i.e .2 not 2 core
Mohamed Ayman:
Yes, you requested 2000m but you need to request 200m.
Basavraj Nilkanthe:
thats great finding, thank you guys
Basavraj Nilkanthe:
i will test it again
Basavraj Nilkanthe:
Thanks Guys, It is working as expected after putting --requests=cpu=.2 and really it was consuming my more time while finishing lighting lab and I was manage to finish first four questions in 35 min and because of this issue, it took this time… So it is important to read questions carefully before taking exam …
