- added retainPods flag to take in the number of specialized pods to retain - add retainPods in both the create function and update function command - modify crd keys to be typed instead of string - keep track of function generation in case of update function operation - add delete handler function to make sure specialized pods are deleted in case function is deleted --------- Signed-off-by: Sanket Sudake <sanketsudake@gmail.com> Signed-off-by: Pranoy Kundu <pranoy1998k@gmail.com> Co-authored-by: Pranoy Kundu <pranoy1998k@gmail.com>
