Description
Expected Behavior
The informer should have only pods with label app.kubernetes.io/managed-by=tekton-pipelines or the value of the config default-managed-by-label-value
https://github.com/tektoncd/pipeline/blob/main/config/config-defaults.yaml#L52
Actual Behavior
The informer has too many pods in his memory.
Steps to Reproduce the Problem
- Modify the code of the pipeline controller to display the number of pods in the informer
go func() {
for {
pods, err := podInformer.Lister().List(labels.Everything())
if err != nil {
logger.Fatal(err)
}
logger.Error(len(pods))
time.Sleep(time.Second)
}
}()
- Create a TaskRun
- Create a pod with a label
app.kubernetes.io/managed-by: not-tekton-at-all
