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.
The test assumes that all nodes have Ceph client utilities installed.
Ceph RBD container is hand crafted to be really minimal. It creates a new RBD
on startup, which can take up to several minutes on busy machines.
iSCSI and RBD volumes don't work as Kubernetes services - these protocols
are broken by S-NAT created by kube-proxy - at least iSCSI exhanges real
IP address of the iSCSI target as part of the protocol.
This reverts commit 118004c166.
Before this patch the endpoint IP was used to identify endpoint addresses. This
leads to wrong unification of endpoints of different pods having the same IP (e.g.
non container IP in case of Mesos). This patch takes the EndpointAddress.targetRef.UID
into consideration as well.
Initialize global variable MINION_IPS in setClusterInfo function.
MINION_IPS is defined as a global variable, and is concatenated with other nodeIP.
When setClusterInfo is called for many times, this could cause potential problems.
Such as, you will have MINION_IPS=192.168.0.2,192.168.0.3,192.168.0.2,192.168.0.3 which is obviously wrong.
