The HealthyScope allows you to define an aggregated health probe for all components in same application.

1.Create health scope instance.

apiVersion: core.oam.dev/v1alpha2
kind: HealthScope
metadata:
name: health-check
namespace: default
spec:
probe-interval: 60
workloadRefs:
- apiVersion: apps/v1
kind: Deployment
name: express-server
  1. Create an application that drops in this health scope.
apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
name: vela-app
spec:
components:
- name: express-server
type: webservice
properties:
image: crccheck/hello-world
port: 8080 # change port
cpu: 0.5 # add requests cpu units
scopes:
healthscopes.core.oam.dev: health-check
  1. Check the reference of the aggregated health probe (status.service.scopes).
kubectl get app vela-app -o yaml
apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
name: vela-app
...
status:
...
services:
- healthy: true
name: express-server
scopes:
- apiVersion: core.oam.dev/v1alpha2
kind: HealthScope
name: health-check

4.Check health scope detail.

kubectl get healthscope health-check -o yaml
apiVersion: core.oam.dev/v1alpha2
kind: HealthScope
metadata:
name: health-check
...
spec:
probe-interval: 60
workloadRefs:
- apiVersion: apps/v1
kind: Deployment
name: express-server
status:
healthConditions:
- componentName: express-server
diagnosis: 'Ready:1/1 '
healthStatus: HEALTHY
targetWorkload:
apiVersion: apps/v1
kind: Deployment
name: express-server
scopeHealthCondition:
healthStatus: HEALTHY
healthyWorkloads: 1
total: 1

It shows the aggregated health status for all components in this application.
