I created a simple integration exposing a REST endpoint.
This endpoint when invoked consumes a lot of CPU (100%) for testing...
I defined the traits:
- container.limit-cpu=1000m
- container.request-cpu=1000m
After that, I created the hpa resource:
- kubectl autoscale it my-integration-high-cpu-usage --min=1 --max=3
When I started to burst the CPU with a lot of requests (testing) I
noticed that no extra pods are created via HPA...
I consulted the hpa resource with: kubectl get hpa
my-integration-high-cpu-usage -o yaml
And there was an error:
- lastTransitionTime: "2022-03-31T16:30:07Z"
message: 'the HPA controller was unable to get the target''s
current scale:
Internal error occurred: the spec replicas field
".spec.replicas" does not
exist'
reason: FailedGetScale
status: "False"
type: AbleToScale
So, after that, I set the replicas in spec field with:
- kubectl scale integrations my-integration-high-cpu-usage --replicas 1
And started the stress test again... and now the HPA has done its job.
My question here is, why the integration isn't created with the
"replicas: 1" as default?
Is There any way to define the "replicas: 1" in the integration
resource when the kamel CLI runs it?
