dgrove-oss opened a new issue #355: better readiness probe for kafka URL: https://github.com/apache/incubator-openwhisk-deploy-kube/issues/355 We need a good external check for Kafka being ready that can be used in the `openwhisk.readiness.waitForKafka` macro in _readiness.tpl. The current macro checks for zookeeper being up, then sleeps for 10 seconds (assuming this is enough time for kafka to be ready). Ideally, we could make a connection to the kafka service and verify that it is actually ready. This would (a) be accurate and (b) usually cut about 5 seconds of latency out of Chart deployment since the 10 second sleep is fairly conservative.
