Using Helm Chart and Kubernetes, pass a file to the container during postStart

1/13/2020

I'm using Helm Chart, Kubernetes and containers.
I need to pass a file to the container during postStart.
The file will be used in the postStart script.
The file should change from one deployment to another and should be part of the Helm Chart values.

Is the above scenario supported? Any suggestions or examples of how to implement it?

Follow the below steps

Create a ConfigMap object using the file/script that you want to use in postStart event
Mount the ConfigMap as volume inside the pod
You should be able to access the file/script inside pod/container.
