this is mainly to ensure integration tests (which all end in _test)
are properly bossed around for their imports
I had to adjust some of the _test files to adhere to existing
reverse_rules specified elsewhere
The service allocator is used to allocate ip addresses for the
Service IP allocator and NodePorts for the Service NodePort
allocator. It uses a bitmap backed by etcd to store the allocation
and tries to allocate the resources directly from the local memory
instead from etcd, that can cause issues in environment with
high concurrency.
It may happen, in deployments with multiple apiservers, that the
resource allocation information is out of sync, this is more
sensible with NodePorts, per example:
1. apiserver A create a service with NodePort X
2. apiserver B deletes the service
3. apiserver A creates the service again
If the allocation data of apiserver A wasn't refreshed with the
deletion of apiserver B, apiserver A fails the allocation because
the data is out of sync. The Repair loops solve the problem later,
but there are some use cases that require to improve the concurrency
in the allocation logic.
We can try to not do the Allocation and Release operations locally,
and try instead to check if the local data is up to date with etcd,
and operate over the most recent version of the data.
go fmt
make func private
refactor config_test
Two primary refactorings:
1. config test checkPath method is now each a distinct test
run (which makes it easier to see what is actually failing)
2. TestNewWithDelegate's root path check now parses the json output and
does a comparison against a list of expected paths (no more whitespace
and ordering issues when updating this test, yay).
go fmt
modify and simplify existing integration test for readyz/livez
simplify integration test
set default rbac policy rules for livez
rename a few functions and the entrypoint command line argument (and etcetera)
simplify interface for installing readyz and livez and make auto-register completion a bootstrapped check
untangle some of the nested functions, restructure the code
add startup sequence duration and readyz endpoint
add rbac bootstrapping policy for readyz
add integration test around grace period and readyz
rename startup sequence duration flag
copy health checks to fields
rename health-check installed boolean, refactor clock injection logic
cleanup clock injection code
remove todo about poststarthook url registration from healthz
Add a smoke test that checks for the existence of some representative
paths from the apiextensions-server and the kube-aggregator server,
both part of the delegation chain in kube-apiserver.
abstract out etcd server creation
test/integration/framework: cleanup master_utils.go
kube-apiserver: move StartTestServer tests into test/integration/master
Fix the failing scale test
kube-apiserver's TestServer now returns a struct instead of individual values
