Excellent illustration of the init container under the hood. I loved it. in our environment for pod deployment we uses the init container side-car to get the deployment configuration from the vault. this is a subject that not too many Engineers delve into. and kubectl describe pod should tell you if the init container has any issue before starting the real application container. Thank you for the inside you shared in your illustration. you are the Man!!
Thanks again. Mat.

It's good effort of you for making such nice videos, but small suggestion from my side, plz try to avoid the sound "cho cho" (observe at 11th sec) which is repeating throughout all the videos.

Hi Venkat, Once again many more thanks, This video helps a lot to understand the concepts, what is the main difference between jobs and INIT containers.

nice video Venkat, thank you for sharing.
Is init container same as pause container or infra container? I know pause container is the first container that gets running in a pod to serve as the basis of the namespace and PID 1.

A very informative video, thanks and keep it up. Although I don't get it when you got only one pod running in one worker node #12:44 but you can access nginx index page from both node at browser

your the best in teaching man, seriously, I have a small doubt, In init YAML file, under init container path for saving HTML is different and under container nginx mount path is different, how do index.html file will copy to the /usr/share/nginx/html, since it's path is /nginx-data

Hi Venkat, Your videos are much informative and has been a great help for me. I have been learning from your videos. I just have one question, can we see the logs of the init container?

[saivenkataratnamemmani]

Thank you

does init container must have image specified or we can specify just command that we want to execute?

Hi, First of all thanks for the video. We have some different scenario. We would like to prepare our node before depployment happends. For example we want to install Nvidia drivers because we have application which uses gpu to be deployed on this node of cluster. Is it possible to run script which will install Nvidia drivers before application deployment? Any guidance would be pretty helpful. Thanks again for the video. Keep up the good work.

It's OK to speak in your native accent. Everyone is able to make out the difference between a fake and real accent.
