I think we need to debug the e2e tests; something keeps causing then to time out during rollout of some deployment. |
|
(most likely unrelated to the PR) |
|
We need to investigate why the e2e tests fail. I don't think it is related to this PR. |
|
With #319 the e2e test should work again. Can you rebase the PR? |
because of the way the iptables rules are reconciled, having the encapsulation rules at the end of the slice of rules results in them being deleted and re-added many times, even though they are very static. Prepending them to the slice of rules prevents this from happening, making that iptables chain more stable and saving a bunch of roundtrips to iptables.
