HTTP lookup queries an HTTP endpoint.

users-topology.yaml

apiVersion: canaries.flanksource.com/v1
kind: Topology
metadata:
  name: users
  namespace: default
spec:
  schedule: '@every 30s'
  components:
    - name: Users
      type: Employees
      icon: person
      lookup:
        http:
          - url: https://jsonplaceholder.typicode.com/users
            display:
              expr: |
                dyn(json).map(c, {
                  'name': c.name,
                  'type': 'person',
                }).toJSON()

This topology will create a root "users" component with all the users returned by the HTTP endpoint as its child components.
