Hi Akila, Right, I get your point on the length limitation, but this is how Kubernetes has described Labels and Annotations:
*We'll eventually index and reverse-index labels for efficient queries and watches, use them to sort and group in UIs and CLIs, etc. We don't want to pollute labels with non-identifying, especially large and/or structured, data. Non-identifying information should be recorded using annotations.* The idea is to use labels for all identifiers. http://kubernetes.io/v1.0/docs/user-guide/labels.html On Sun, Sep 20, 2015 at 10:05 PM, Akila Ravihansa Perera <raviha...@wso2.com > wrote: > Hi Imesh, > > Yes, I tried adding them as labels but ran into a problem since label > length cannot be greater than 63 characters.
