ResourceSelector

We use resource selectors to link components with each other

Field	Description	Scheme
id	ID of the component	string
name	Name of the component	string
namespace	Namespace of the component	string
types	List of types of the component	[]string
statuses	List of statuses of the component	[]string
labelSelector	Labels to select the component in kubernetes format	string
fieldSelector	Property fields of the component in kubernetes format (or database columns: owner, topology_id, parent_id)	string
agent	ID or name of the agent (Default: local agent). Use 'all' to select all the agents	string
cache	One of 'no-cache' (should not fetch from cache but can be cached), 'no-store' (should not cache) or 'max-age=X' (cache for X duration)	string

A resource selector fetches components that satisfy all the parameters, you can use multiple selectors to aggregate

Example

kind: Topology
metadata:
  name: Example
spec:
  components:
  - name: Components with healthy status in kube-system namespace of all agents
    selectors:
    - statuses: ['healthy']
      namespace: kube-system
      agent: all

  - name: Components with Node type with spot instance property labelled with gpu tag
    selectors:
    - types: ['Kubernetes::Node']
      fieldSelector: 'instance-type=spot'
      labelSelector: 'sku-type=gpu'

  - name: Components with labels of team payments and team orders
    # Using multiple selectors to aggregate
    selectors:
    - labelSelector: 'team=payments'
    - labelSelector: 'team=orders'
