@mikemorris , thanks for making the PR. I am new to the world of consul-dataplane. Out of curiosity, do we have similar proxy shutdown feature in consul core ( |
Nope, this has been a longstanding feature/fix request that we're looking to address now, added relevant issue references to original post for context. The eventual implementation of graceful shutdown functionality in consul-dataplane, which these flags are intended to configure, will be managed by Helm configuration for both regular pods and jobs and triggered by a preStop hook in consul-k8s for jobs. |

The implemented functionality may differ slightly because of how we'll be handling connection draining...
