There was a problem hiding this comment. I repurposed this to support linux as well. @jkh52 what is the concern about the number of DaemonSets? There was a problem hiding this comment. In my experience with DaemonSets, when there are enough nodes (example: hundreds or more) and HA clusters (3 masters) the proxy-server could have runaway memory ballooning (at times like rolling master restarts, when we expect many agent grpc connections). I found the root cause to be: the agent authentication path in proxy-server was getting throttled by client-go and accumulating resources. I found stability improvements by tuning:
There was a problem hiding this comment. Are there node startup scripts that this could be placed in? Or is this solving a chicken/egg problem where Antrea network fabric is not known to be selected before the node boots? |
