dgrove-oss opened a new issue #382: Improve configuration of invoker.containerFactory.nameservers URL: https://github.com/apache/incubator-openwhisk-deploy-kube/issues/382 When the providers are enabled with the DockerContainerFactory, we should probably default the nameserver configuration parameters of the invoker to use Kuberetes dns service. This allows user action containers (including those used by the provider packages) to access other kubernetes services using cluster-internal dns. The provider's actions need this to be able to reach couchdb and operate properly. This is a less secure setup (it allows user actions to be aware they are running within a Kube cluster and to interact with other pods running in the cluster), but is probably what a user is expecting when they deploy OpenWhisk on their own Kubernetes cluster. Sketch of implementation, if the user didn't explicitly set invoker.containerFactory.nameservers when they deployed the chart, then we should run a script as part of invoker startup that parses /etc/resolv.conf to get the values set for the invoker pod by Kube. We then pass those through the appropriate PureConfig env variables so that things are properly configured without a manual user step of figuring out the ClusterIP of kube-dns / core-dns service.
