In our google cloud (kubernetes backed) configuration of multiple projects, workloads and service (load-balancers), we specifically configure load-balancers but the configuration seems to change.
We specifically add nodes to our load-balancers, after a while, all of our nodes (from different pools) end up attached to all our load balancers. After they have been magically added back to the load-balancer, we remove them (again), and then sometime later, they're all back.
I realize there is a lot of missing implementation information but was hoping there was some well-known patterns someone thinks we might not be following. I will try my best to post configuration details.
