[@umershaikh531]

so basically namespaces give you isolations and you can create pods with same name in different namespaces. resource quota is basically applied over namespaces and limit-ranges are set over pod, container, pvc and in case of resource quota you can also mention pod limit configmap limit too.

[@varunindrajeetanand95]

It is great experience while Learning DevOps by Bhupinder sir ... He remove my thinking about DevOps as a hard one only for Experienced one .

How many times we can waive off bill??

[@abhijitherkal4385]

one doubt i had .. what if we mention request value more than 1 and we dont define limit value ..in that case what will be the value of limit ???

[@gouravmaitra8147]

Bhupi sir, apne lab main limit define nehi kiye to output of limit aya '1'. lekin apne theory main bataya output ayega '0' unlimited. to kya hamesha jo bhi request karunga usse zyda ek value limit main ayega ?

[@sherazhussainmughal2784]
