In both etcd and k8s don't error log NXDOMAIN as this log spams the logs
for no good reason.
Fixes#568
Better long term solution is log rate limiting for both *log* and
*error*.
* add cidrs opt
* remove state data from middleware object
* update k8s docs
* Add integration tests
* add unit tests for cidr and pods config
* more README fixes, separate dev notes
* adjust section headers
* fix typo
* dont require/allow "_" prefix for srv wildcard fields
* streamline parse/validation of req name
* removing nametemplate
* error when zone not found, loopify unit tests
This checks if the next middleware to be called is nil, and if so returns
ServerFailure and an error. This makes the next calling more robust and
saves some lines of code.
Also prefix the error with the name of the middleware to aid in
debugging.
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.
Be more explicit in the logs when a notify fails.
New notify error message looks like:
2016/11/07 18:21:42 [ERROR] Notify for zone "example.org." was not accepted by "8.8.8.8:53": rcode was "SERVFAIL"
Correctly pick up secondaries
When multiple secondary are specified make sure they are picked up.
Fixes#393#398
The watchers were still trying to process raw v1 objects which
failed to be added to the store. This meant new services and
namespaces created after CoreDNS started would not be discoverable.
Add a filter function that converts watch events with v1 objects
to events with api objects.
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
* middleware/metrics: add more metrics
middleware/cache:
Add metrics for number of elements in the cache. Also export the total
size. Update README to detail the new metrics.
middleware/metrics
Move metrics into subpackage called "vars". This breaks the import
cycle and is cleaner. This allows vars.Report to be used in the
the dnsserver to log refused queries.
middleware/metrics: tests
Add tests to the metrics framework. The metrics/test subpackage allows
scraping of the local server. Do a few test scrape of the metrics that
are defined in the metrics middleware.
This also allows metrics integration tests to check if the caching and
dnssec middleware export their metrics correctly.
* update README
* typos
* fix tests
This fix adds several needed comments in
`middleware/kubernetes/nametemplate/nametemplate.go`
to clean up golint output.
There are still 3 places that needs proper docs:
```
middleware/kubernetes/nametemplate/nametemplate.go:64:1: comment on exported type Template should be of the form "Template ..." (with optional leading article)
middleware/kubernetes/nametemplate/nametemplate.go:72:1: comment on exported method Template.SetTemplate should be of the form "SetTemplate ..."
middleware/kubernetes/nametemplate/nametemplate.go:188:1: comment on exported type NameValues should be of the form "NameValues ..." (with optional leading article)
```

This still needs cleanup, but this is a first pass the cleans some
cruft and documents our style (in middleware.md) and makes all the
docs match that style.
* 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
