The wrong assumptions and choices can undermine your move to Kubernetes. Instructions on how to implement and scale Kubernetes abounds. What’s missing from these discussions? How do you make developers be super-productive on Kubernetes? Based on lessons gleaned from both large organizations (Netflix, Uber), mid-sized (Yelp, HubSpot), and small, Richard and Rafael discuss the key steps these organizations took to optimize their developers’ productivity as they migrated to Kubernetes.

DESCRIPTION:
Secret holds secret data of a certain type. The total bytes of the values in the
Data field must be less than MaxSecretSize bytes.
FIELDS:
apiVersion <string>
APIVersion defines the versioned schema of this representation of an
object. Servers should convert recognized schemas to the latest internal
value, and may reject unrecognized values. More info:
