This doesn't seem to be the case in your particular deployment, however something similar happened to me too and I'll post it in case someone Googles this question.
I had a failing job without a Delete policy, and this made it deploy itself 1000 times for some reason. Specifying a delete policy fixed the issue.
As stated in the following link:
At v1.11, Kubernetes supports clusters with up to 5000 nodes. More specifically, we support configurations that meet all of the following criteria:
No more than 5000 nodes No more than 150000 total pods No more than 300000 total containers No more than 100 pods per node
Your event log shows an insufficient pods
If your cluster doesn't have more than 10 working nodes, the scheduler cannot schedule less than 100 pods per node (and respect the fourth bound).
The same limitations occur with a kubernetes version before v.1.11.
