Also transfer the Kubelet from using ContainerManifest.ID to source specific
identifiers with namespacing. Move goroutine behavior out of kubelet/ and
into integration.go and cmd/kubelet/kubelet.go for better isolation.
The current tests for the health package utilize a fake HTTP client
for testing health checks and only cover a limited set of test cases.
This patch removes the need for mocks by using the httptest package
from the standard library. After removing the fake HTTP client a bug
was found in the health.Check function; it incorrectly assumes that
a http.Response is always non-nil. Fix the issue by moving the defer
that closes the http.Response.Body after error handling.
Related tests in the registry package have be refactored to work with
the changes made to the health.Check function. All methods that implement
the health.HTTPGetInterface interface now return a http.Response with
with a noop http.Response.Body.
This patch does not introduce any changes in behavior.
The pause image is a 240KB image that simply pauses waiting on a signal.
Use this for the net container which only needs to act as a placeholder.
Current net image is ~2.5MB. From my tests, this reduces startup time
for the net container from ~14s to ~6s.
The tests for Docker image name parsing are repetitive and do not
cover enough test cases.
Refactor the tests to use table testing and add additional test cases.
This patch completes a TODO item for the kubecfg package test suite by
removing the expectNoError helper function, which does not reduce enough
typing to justify its usage.
When no tag is given to Docker pull, it downloads all tags. This could be a
significantly large number of images and in the end we only ever run
:latest.
This patch completes a TODO item for the replication_controller test
suite by removing the expectNoError helper function, which does not
reduce enough typing to justify its usage.
The -etcd_servers flag is used inconsistently by the Kubernetes commands,
both externally and internally.
This patch fixes the issue by using the same type to represent a list of
etcd servers internally, and declares the -etcd_servers flag consistently
across all commands.
This patch should be 100% backwards compatible with no changes in behavior.
Implemented via HTTP and websocket. A test is present but this isn't
yet wired into anything.
Eventual purpose of this is to allow a scheduler to watch for new pods.
Or allow replication controller to watch for new items it controlls.
Generally, it'll be good to turn everything possible into a push instead
of a poll.
