dcos

I'm trying to install Kafka on Mesos. Installation seems to have succeeded. vagrant@DevNode:/dcos$ dcos package install kafka This will install Apache Kafka DCOS Service. Continue installing? [yes/no] yes Installing Marathon app for package [kafka] version [0.9.4.0] Installing CLI subcommand for package [kafka] version [0.9.4.0] New command available: dcos kafka The Apache Kafka DCOS Service is installed: docs - https://github.com/mesos/kafka issues - https://github.com/mesos/kafka/issues vagrant@DevNode:/dcos$ dcos package list NAME VERSION APP COMMAND DESCRIPTION kafka 0.9.4.0 /kafka kafka

I'm running DC/OS 1.7 with marathon-lb. spray.io 1.3.3 is returning 400 to all marathon-lb/HAProxy heath check calls: request has a relative URI and is missing a Host header so marathon-lb never routes any requests to the service. The health check in the marathon json is: "healthChecks": [ { "path": "/health", "protocol": "HTTP", "portIndex": 0, "gracePeriodSeconds": 10, "intervalSeconds": 2, "timeoutSeconds": 10, "maxConsecutiveFailures": 10, "ignoreHttp1xx": false } ], and the logging by spray.io in the docker container is: [WARN] [08/19/2016 23:53:42.534] [asp-service-akka.actor.default

I'm looking for some pros and cons of whether to go with Marathon and Chronos, Docker Swarm or Kubernetes when running Docker containers on DC/OS. For example, when is it better to use Marathon/Chronos than Kubernetes and vice versa? Right now I'm mostly into experimenting but hopefully we'll start using one of these services in production after the summer. This may disqualify Docker Swarm since I'm not sure if it'll be production ready by then. What I like about Docker Swarm is that it's essentially just "Docker commands" and you don't have to learn something completely new. We're already
