I am very new to Helm and Kubernetes. I have a use case where, whenever there is a helm upgrade
helm upgrade xxx --values yy.yamlI need to trigger invocation of a method in my docker image which is deployed onto the kubernetes pods ,so that i can work on the changes encountered in yy.yaml in the image code . Do we have some way of doing it ? Please help me here.
Though your problem is not clear to me but i think, You can use helm hook to do the same thing. Please check documentation.
You can certainly use pre-upgrade hook to invoke your function.
