Prevent deployer pod creation conflicts #8588
Conversation

LGTM |

Does this handle cases where the controller's pod cache is not populated yet (like on startup)? What about cases where the cache has not yet observed a deletion of the pod? |
This controller doesn't use a pod cache, so everything is responsive to updates to the RC. No caching issues to worry about. |

Can you create a soak extended test that proves this fixes the issue? We don't have to merge it, but I want to see code and a run that proves it's not regressing |

Take advantage of a single-controller assumption by checking for the existence of deployer pods before trying to create new ones. This allows the controller to progress the phase of the deployment without incurring a resource conflict during create under most circumstances- a behavior which can result in poor interactions with the quota system which will charge quota for the conflicting pod.
