best approch for filtering

Question

I have a list of entities (profiles) I have another list of entities (openapis)

each openapi can be pointed at by several profiles

ex: openapis: "Alpha", "Beta"

profiles: profile1 > "Alpha" profile2 > "Alpha" profile3 > "Beta"

I need to display list of openapis ["Alpha", "Beta"] and their pointing profile ex:

"Alpha" : profile1 ,profile2

"Beta": profile3

I dont have database Im using "kebernetes" CRs what is the best approch for this ? I know I can just filter profiles for each openapi but is there a better approch ?

Answer 1

Given that you're working with Kubernetes Custom Resources (CRs) and you don't have a traditional database, you might need to handle this association in your application logic. Here are a couple of approaches you can consider:

You can maintain an in-memory data structure to keep track of the associations between openapis and profiles. This can be done using a JavaScript object where the keys are openapis and the values are arrays of associated profile Whenever you add or remove a profile from an openapi, you update this data structure accordingly. This approach is suitable if your data set is not too large and can fit comfortably in memory.

const associations = {
  "Alpha": ["profile1", "profile2"],
  "Beta": ["profile3"]
};

If your entities (profiles and openapis) are represented as Kubernetes Custom Resources, you can use labels to associate profiles with openapis. Labels are key-value pairs that can be attached to Kubernetes resources.

For example, you can add labels like:

apiVersion: yourapi.example.com/v1
kind: Profile
metadata:
  name: profile1
  labels:
    openapi: Alpha
---
apiVersion: yourapi.example.com/v1
kind: Profile
metadata:
  name: profile2
  labels:
    openapi: Alpha
---
apiVersion: yourapi.example.com/v1
kind: Profile
metadata:
  name: profile3
  labels:
    openapi: Beta

Then, you can use Kubernetes API queries to retrieve profiles associated with a particular openapi. This approach provides a more declarative way to represent associations.
