Kubernetes Training from Basic to Advanced | 20+ ISSUE LIST

What you’ll learn
My session is fully based on Real time issues and Scenario based on Kubernetes Production Environment.
This session will be helpful for those folks who have good knowledge about Kubernetes but don’t have a chance to get a job in Kubernetes.
or no knowledge about real time scenarios in industry, due to the lack of this thing they are not confident during the interview
I have explained my Kubernetes infrastructure like Cluster size, Team size and all tools
we have used in industry like monitoring tool, logging tool, backup tool. and also discussed on scenario based QS with Answer for Interview
I have covered few issue like…some of the Pod having ImagePullBackOff ERROR, How do we fix this issue what is root cause of this issue
One of the Pods are in CrashloopBackOff State – what is the reason and how do we fix those issue
One OF Pod are stuck in Pending State – What is the reason and how do we fix this issue
So i have noted down all Issue what i faced in my Kubernetes journey and created a Live troubleshooting session with Solution and RCA

Does anyone want to learn real time Training Based on Kubernetes Production Environment, i have more than 20 plus real time production issue lists with solutions plus client requirements . I have noted all the issues that I faced during my job journey in Kubernetes. In this session I have fixed all of those issues and provided the root cause of the issue. How are we fixed?

Most of the interviewer asked you to tell me about challenges which you were working on in your Kubernetes project.

After watching my session that would be more helpful. I have covered all the Topics which are based on the real time environment, which generally I worked and have faced those issues in my Kubernetes project.

This session will be helpful for those folks who have good knowledge about Kubernetes but don’t have a chance to get a job in Kubernetes or no knowledge about real time scenarios in industry, due to the lack of this thing they are not confident during the interview. I will explain about Kubernetes infrastructure like all tools we have used in industry, and also share a list of interview questions.

Nowadays most of the companies have adopted containerization based applications and deploy applications over Kubernetes Platform so there are a lot of opportunities only on Kubernetes profile itself. Most guys have confusion that only devops openings are there but it’s not true…Generally devops guys set up CICD Pipeline or Set Release pipeline over kubernetes environment. So company needs seperate team to manage entire kubernetes infrastructure, Generally in project 100+ kubernetes cluster 400+ application running as a pod so we need seperate team to manage entire infrastructure and we have to upgrade cluster time to time also.
