* plugin/kubernetes: wait until api is ready
Wait for HasSynced before allowing startup to avoid startup race.
Also do a small refactor in findServices() to pull a check out of the
loop - only needs to be done once.
* sigh
* healthchecks: check on every 3rd failure
Check on every third failure and some cleanups to make this possible. A
failed healthcheck will never increase Fails, a successfull healthceck
will reset Fails to 0. This is a chance this counter now drops below 0,
making the upstream super? healthy.
This removes the okUntil smartness and condences everything back to 1
metrics: Fails; so it's simpler in that regard.
Timout errors are *not* attributed to the local upstream, and don't get
counted into the Fails anymore. Meaning the 'dig any isc.org' won't kill
your upstream.
Added extra test the see if the Fails counter gets reset after 3 failed
connection.
There is still a disconnect beween HTTP healthceck working the proxy (or
lookup) not being able to connect to the upstream.
* Fix tests
* doc update
Go through all README and fix mistakes, extend example and let more
corefile snippets be test for validity.
* Cant use spefic addr in test
* healhcheck: various cleanups
Network wasn't used. IgnorePaths wasn't used. Move checkdown function to
common function shared between proxy protocols. And some naming fixed.
Also reset the Fails on a succesful healthcheck back to 0.
remove newlines from log
* compile
* fix test
Add a full test server impl in this new package + tests. Move
dnsrecorder into this package as well and finish up the commented out
tests that were left in the old dnsrecorder package.
Update all callers and tests.
* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat
