2016-12-02Add A lookup for headless services (#451)Gravatar Chris O'Haver 1-6/+30
2016-11-15K8s Test Cleanup and Service PTRGravatar John Belamaric 1-1/+8
Change the CI setup for K8s to be simpler. Now it just creates a set of objects via a yaml file, making it very easy to modify the tests. Implement PTR for services.
2016-11-13Fix various issues with formatting and typos (#424)Gravatar Michael Grosser 1-1/+1
* Fix typos * Simplify code * Fix error usage
2016-11-11More idiomatic GoGravatar Miek Gieben 1-5/+5
2016-11-10Return NXDOMAIN when no items match query (#422)Gravatar Chris O'Haver 1-5/+7
* When no records match, reply with NXDOMAIN * Implement in IsNameError * case for unexposed namespace. k8s integation tests * Fix imports order. Lower case of err strs.
2016-11-05BackendService: add Reverse method (#381)Gravatar Miek Gieben 1-10/+14
Add a Reverse method to BackendService because different backends want to to do diff. things. This allows etc/k8s to share even more code and we can unify the PTR handling.
2016-11-05Fix k8s client (#379)Gravatar John Belamaric 1-23/+29
* Fix k8s client to use client-go * Fix Kubernetes Build Issue The client-go code requires you to vendor. I have done a hack here in the Makefile to vendor it to version 1.5. But looks like we will need to do this the 'right' way soon. * Convert v1 to api Objects in List Functions Also removed the endpoint controller which was not used for anything. The Watch functions may still need the same treatment. * Vendor client-go release-1.5 * Fix basic SRV feature This is actually not serving SRV records correctly, but this should get it to work as it did prior to the k8s client changes. Another fix will be needed to serve SRV records as defined in the spec. * Add additional output in test result Add the response to the test output. * Fix erroneous test data
2016-10-30ServiceBackend interface (#369)Gravatar Miek Gieben 1-20/+40
* Add ServiceBackend interface This adds a ServiceBackend interface that is shared between etcd/etcd3 (later) and kubernetes, leading to a massive reduction in code. When returning the specific records from their backend. Fixes #273

2016-09-21Fix k8s build (#278)Gravatar Manuel Alejandro de Brito Fontes 1-5/+4
2016-09-07Cleanup: put middleware helper functions in pkgs (#245)Gravatar Miek Gieben 1-3/+3
Move all (almost all) Go files in middleware into their own packages. This makes for better naming and discoverability. Lot of changes elsewhere to make this change. The middleware.State was renamed to request.Request which is better, but still does not cover all use-cases. It was also moved out middleware because it is used by `dnsserver` as well. A pkg/dnsutil packages was added for shared, handy, dns util functions. All normalize functions are now put in normalize.go
2016-08-23remove debugGravatar Miek Gieben 1-2/+0
2016-08-23Fix k8s integration tests (#231)Gravatar Michael Richmond 1-27/+28

2016-08-19Make CoreDNS a server type plugin for Caddy (#220)Gravatar Miek Gieben 1-38/+10
* Make CoreDNS a server type plugin for Caddy Remove code we don't need and port all middleware over. Fix all tests and rework the documentation. Also make `go generate` build a caddy binary which we then copy into our directory. This means `go build`-builds remain working as-is. And new etc instances in each etcd test for better isolation. Fix more tests and rework test.Server with the newer support Caddy offers. Fix Makefile to support new mode of operation.
