For front end we also need tls certificates. If tls termination configured in application level we need to create a secret object and mount as volume. If tls certificates not configured at application level so we need to make sure tls certificates available either at ingress level or lodbalancer level. And please make video on operators and crd's

[@DeekshithSN]

Thanks for watching and adding more points which benefits my audience. Sure will plan to do video on operator :)

[@awssoorinje747]

Thanks for your insightful videos! Could you also cover real-time scenarios in ArgoCD and Istio? They're missing from many KZbin playlists.

[@DeekshithSN]

Thanks for watching sure will plan videos on argocd and istio 😊

[@MaheshAnnam-u5i]

Thank you so much, Deekshith. As mentioned, please create a video regarding Operators and CRDs with Realtime usage cases. We profoundly indebted for your generous and friendly gesture for creating content considering our requests.

In second scenario ie. Golang Application and redis why not use nodeselector or taints and tolerants concept we will be able to achieve the requirement using this also right? Correct me if I am wrong. Beginner in Devops

[@DeekshithSN]

Thanks for watching :) For the second scenario I would say node selector wont work well, because of below reasons 1. Many times only one or few nodes might be available with specific label. Lets say I need 8 replicas and there only 4 nodes with specific label. in this case node selector or affinity wont workout 2. By using node selector its not guaranteed each pod will always goes to different nodes, still there is chance that multiple pods can go on single node. 3. Also the requirement is always deploy app pod where redis being deployed. if we go with node selector or node affinity there is chance that pod can be scheduled on node where redis is not being deployed.

[@kedar1704]

@@DeekshithSN Got it!! Thanks for the clear explanation

small correction: high latency means slow communication,........... and low latency means faster communication in 13:55

[@DeekshithSN]

Thanks for correcting it :)

[@muruligowda2985]

do a video on operator bro

[@akkyintish2519]

What is API testing stage after kubernetes deploy please tell me simple way if possible

[@DeekshithSN]

Thanks for watching the video 😊 Firstly I want say every company or client will have different stages in their cicd flow But one of the project where I was involved we had stage to apply the changes and execute some api's to test whether application really works or not, that stage we used to call it as API testing

[@navabshaik3221]

I have one interview qution I deployed a deployment object with 2 replicas. After deploying my pod are not shown when I do k get pods Pods are not shown. But when I do K get all it shows deployment object and replica set but shown as 0/2 like this what are the reasons for pods not shown?

[@shankarkolte7111]

Pods may be in pending state becoz they are not getting enough resources in that particular namespace

[@DeekshithSN]

Thanks for watching the video, there might be many reasons 1. All the nodes in k8s cluster might be unhealthy state 2. Requested resources might not be available in k8s nodes 3. Might be you are deploying to namespace where namespace attached with resources quota. But in your pod spec you wouldnt defined resources block this might also the reason. I would suggest, do describe on deployment, then you will get know actual reason :)

[@sparker1170]
