I’m not quite sure what’s going on here, but I’m unable to have to containers successfully complete the Readiness/Liveness checks. I’m implemented the changes to distributed.go, and agent.go. All tests pass.
But when I run the helm chart, keep getting failed health checks.
I realize there are many things that may be amiss here, just wondering if anyone has experience anything? Manually running k exec -it proglog-0 -- /bin/grpc_health_probe -addr=localhost:8400 naturally results in a timeout error… I’ve run the code from the books repo as is and can’t get it to pass either.
