Michael Richmond	289f53d386	k8s middleware cleanup, testcases, basic SRV (#181) ... * Removing unnecessary gitignore pattern * Updating Makefile to run unittests for subpackages * Adding Corefile validation to ignore overlapping zones * Fixing SRV query handling * Updating README.md now that SRV works * Fixing debug message, adding code comment * Clarifying implementation of zone normalization * "Overlapping zones" is ill-defined. Reimplemented zone overlap/subzone checking to contain these functions in k8s middleware and provide better code comments explaining the normalization. * Separate build verbosity from test verbosity * Cleaning up comments to match repo code style * Merging warning messages into single message * Moving function docs to before function declaration * Adding test cases for k8sclient connector * Tests cover connector create and setting base url * Fixed bugs in connector create and setting base url functions * Updaing README to group and order development work * Priority focused on achieving functional parity with SkyDNS. * Adding work items to README and cleaning up formatting * More README format cleaning * List formating * Refactoring k8s API call to allow dependency injection * Add test cases for data parsing from k8s into dataobject structures * URL is dependency-injected to allow replacement with a mock http server during test execution * Adding more data validation for JSON parsing tests * Adding test case for GetResourceList() * Adding notes about SkyDNS embedded IP and port record names * Marked test case implemented. * Fixing formatting for example command. * Fixing formatting * Adding notes about Docker image building. * Adding SkyDNS work item * Updating TODO list * Adding name template to Corefile to specify how k8s record names are assembled * Adding template support for multi-segment zones * Updating example CoreFile for k8s with template comment * Misc whitespace cleanup * Adding SkyDNS naming notes * Adding namespace filtering to CoreFile config * Updating example k8sCoreFile to specify namespaces * Removing unused codepath * Adding check for valid namespace * More README TODO restructuring to focus effort * Adding template validation while parsing CoreFile * Record name template is considered invalid if it contains a symbol of the form ${bar} where the symbol "${bar}" is not an accepted template symbol. * Refactoring generation of answer records * Parse typeName out of query string * Refactor answer record creation as operation over list of ServiceItems * Moving k8s API caching into SkyDNS equivalency segment * Adding function to assemble record names from template * Warning: This commit may be broken. Syncing to get laptop code over to dev machine. * More todo notes * Adding comment describing sample test data. * Update k8sCorefile * Adding comment * Adding filtering support for kubernetes "type" * Required refactoring to support reuse of the StringInSlice function. * Cleaning up formatting * Adding note about SkyDNS supporting word "any". * baseUrl -> baseURL * Also removed debug statement from core/setup/kubernetes.go * Fixing test breaking from Url -> URL naming changes * Changing record name template language ${...} -> {...} * Fix formatting with go fmt * Updating all k8sclient data getters to return error value * Adding error message to k8sclient data accessors * Cleaning up setup for kubernetes * Removed verbose nils in initial k8s middleware instance * Set reasonable defaults if CoreFile has no parameters in the kubernetes block. (k8s endpoint, and name template) * Formatting cleanup -- go fmt	2016-07-07 09:40:58 +01:00
Michael Richmond	d04abdf422	BK8s datasource middleware -- PoC for A records (#153) ... * Laying down kubernetes middleware foundation * Duplicated a bunch of code form etcd middleware * Duplicated code hacked to compile and load as a separate middleware * Adding verbose build option to Makefile * Removing stubzone and tls support tls and stubzone support was carried over from base etcd middleware code. Removing to simplify the kube middleware implementation. (For now.) * Adding conf directory for sample conf files * Removing stubzone support from query handler * Remove upstream and proxy from k8s corefile. Not sure that upstream or proxy makes sense for a k8s backed zone. * Comment out use of singleflight serialization * Removing parsing support for "upstream" directive from k8s * Removing upstream directive parsing code * Removing CNAME and TXT lookup implementation * Create README.md Brain-dump of DNS record name assembly and open work items. * Adding notes about wildcard handling * Adding basic k8s API client * Fleshing out methods on k8s connector * Remove PathPrefix from middleware init * Removing incorrect plural * Adding brute-force k8s service lookup functions * Initializing k8s API connector during startup * Hacking around to call k8s connector * Parsing incoming domain name into serviceName and namespace * Improving and simplifying k8s zone matching and label segmentation * Removing unused functions carried over from etcd middleware * Adding basic return of k8s data to DNS client * updated debugging println statements to flag with "[debug]" * removed code in kubernetes.go::Records that was a hold-over from etcd middleware. * Removed some random exploratory hacking. * Minior README.md updates * Updating with demo instructions * Updating README.md with CoreFile and removing completed TODO items * Updating conf file and README to reflect DNS response cache works * Disabling DNS response caching * Adding debug statement on entry to Records() * Changing port number in exampes to port 53. * Misc style and clarity changes * Removing empty function definitions * Adding comment to track future cleanup * Refactoring README to follow style of other middleware * Exposing dataobject field (typo)	2016-06-06 20:49:53 +01:00
