…y-induced pod thrashing
Reason for Change:
aks-engine currently delivers a heapster implementation (for clusters < 1.13) that configures the
Deploymentaddon toReconcile, in order to enforce k8s runtime updates to configuration changes from heapster. In practice, folks are experiencing the theheapster-nannycontainer is inducing regular reconciliations (read: kill/recreate) of theheapsterpod.This sets the
DeploymenttoEnsureExistsinstead, which we expect to fix the above symptom; and will require manual reconciliation (read:kubectl delete pod <heapster pod id>) in order to apply changes to the addon spec.Issue Fixed:
