Refactor `pkg/proxy/config`’s ServiceConfigHandler.OnUpdate and
EndpointsConfigHandler.OnUpdate to different method names as they have
different signatures.
This will let the new proxy
(https://github.com/GoogleCloudPlatform/kubernetes/issues/3760)
implement both interfaces.
Since we won’t need a separate loadbalancer structure (load balancing
is handled in the proxy rules), we will simply handle both event types
from the same object.
The current code assumes the full domain name will not be included,
which is not always the case. This patch adds support for computing the
host tag from a fully qualified domain name.
Systemd doesn't do variable substitution on the name of the command to run, so we have to install
rkt to a directory with an absolute literal path that we can reference with environment variables.
Moves the userspace code in proxy to a sub-package and adds the
ProxyProvider interface.
This is in preparation for landing an implementation of
https://github.com/GoogleCloudPlatform/kubernetes/issues/3760, which
will mostly be in another sub package for iptables.
The EndpointPort struct only stores one port: the port which is used
to connect to the container from outside. In the case of the Mesos
endpoint controller this is the host port. The container port is not part
of the endpoint structure at all.
A number of e2e tests need the container port information to validate correct
endpoint creation. Therefore this patch annotates the Endpoint struct with a
number of annotations mapping "<HostIP>:<HostPort>" to "<ContainerPort>". In a
follow-up commit these annotations are used to validate endpoints in a Mesos
setup.
Before this patch endpoints were validated by container IP and port.
Depending on the endpoint controller logic neither of the two must match for a
valid endpoint (e.g. in a Mesos setup).
This patch checks that the endpoint targetRef points to the right pod by UID,
instead of comparing IPs.
A later patch will make sure the
compared port is the actual container port, not the host port.

Since it takes a while (1-2mins) for kubelet to pulling a big image
(>500MB). Just showing "Pending" for pod status is not very helpful.
This commit introduces a "pulling" event, and inserts it before the
kubelet starts to pull an image.
All binaries in kubenretes show `-` for help and seem to expect `-`. Although
`_` also works. The inconsistencies across the codebase using - and _
result in difficultly using things like grep to find things that need to
be changed.
