* Add fallthrough support for Kubernetes
This enables registering other services in the same zone as
Kubernetes services. This also re-orders the middleware chain
so that Kubernetes comes before other types, in order to make
this work out-of-the-box.
* Remove extra line
* dont require/allow "_" prefix for srv wildcard fields
* streamline parse/validation of req name
* removing nametemplate
* error when zone not found, loopify unit tests
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.
* 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.
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.
* 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
* 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
* Added TLS to k8s client
Added options for TLS kubernetes client connection.
* Fix k8s TLS config option parsing
Brings config option parsing for kubernetes TLS in line with recent changes.
* Put TLS config on one line
Put kubernetes tls config on one line to match style established in etcd tls config.
* Add tls option to README
* Fix linter errors
* More linting fixes
* More docs and making members private that dont need to be public

I plan on reworking the proxy anyway, so I'll leave that be.
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
* Adding debug message when starting k8s controller
* Adding work-around for timing issue in k8s integration tests
* Remove unused import
* Fix Makefile for ast package
* Increase k8s verbosity in travis
* Updating TODO list to find root cause of test issue
* go fmt cleanup
* 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.
* Adding pod setup to kubernetes startup scripts
* Adding template description to k8s README.md
* Fix typo.
* Moving kubernetes setup scripts out of go folder

* Updating comment typo in k8sCorefile
* Adding implementation of label support to filter exposed objects
* Updating TODO list

* Adding tests for parsing `resyncperiod` keyword from Corefile.
8 Updating README.md and conf/k8sCorefile.
* Merge notification code by @aledbf and update for recent changes.
* Fix travis environment to correctly build with k8s.io and forked repositories.
* Refactored kubernetes Corefile parser
* Added lots of Corefile parsing tests
* Updating comment to remove references to Caddy

* Updating documentation for k8s tests
* Avoid downloading kubectl if already exists
* Adding debug statement when namespace is not exposed.
* Adding basic kubernetes integration tests
* Makefile now contains a "testk8s" target. This target requires k8s to
be running.
* Adding test/kubernetes_test.go file with a couple of basic A record
tests.
* Updating k8s integration tests to only run k8s integration tests
* Adding support for namespace wildcards
* Refactoring to move filtering logic to kubernetes.go file

Filtering now handled in kubernetes.go
* Adding wildcard test cases
* Adding skydns startup script. (To allow side by side testing of wildcards.)
* Commenting out record name assmebly based on NameTemplate. Need to improve template before this makes sense.
* Adding basic SRV integration tests
* Need to add verification for additional answer section
* Fixing comments and formatting
* Moving wildcard constants to vars
* Travis test execution appears to be failing on access to these
constants
* Fixing access to util package
* Trying to work around Travis test bug
* Reverting to access kubernetes/util as "util"
Travis breakage is due to "Infoblox-CTO" in src path
