Cluster DNS #8

Closed ethernetdan closed 8 years ago

ethernetdan commented 8 years ago

Kubernetes requires DNS to be run in order to resolve requests to services.

This could be implemented by running the SkyDNS server and kube2sky.

These components could be run either as part of the localkube executable or with an RC and Service.

Isn't it possible that running it as a go routine can be a problem in the future, if they change the way it's launched or it's not so easy to d it as a go routine? Or it's not possible that using a go routine can cause a problem?

Also, running it with an RC and Service, isn't just as trivial as using the add-on scripts on kubernetes repo? (as we will already have a kubernetes running and all things necessary to run the scripts, IIUC)

Compiling localkube with these dependencies definitely runs the risk of breaking changes in the future. Using Godeps (which needs to be added to this repo) allows us to at least guarantee a working build but the drawbacks of potential breaking changes are making my lean towards using RC/Service.

Yup, it would be that easy! I'm thinking that we include it as part of localkube because I would think DNS is essential for the vast majority of Kubernetes users. Thoughts?

Yeah, me too.

Yes, DNS is every time more important and I think it will be mandatory since kubernetes 1.2 due this week, so I think it's essential :)

Thanks a lot, Rodrigo

It looks like skydns should be able to be integrated in the binary. Unfortunately kube2sky does not export any methods that we can call so it will have to be shipped as it's own executable.

Also the setup requires etcd which is already being compiled against.

A service can be used to expose DNS to the cluster
