- Move keygen image mesosphere/kubernetes-mesos-keygen -> mesosphere/kubernetes-keygen:v1.0.0
- Remove resolveip in favor of github.com/karlkfi/resolveip (resolveip.sh)
- Remove util-temp-dir.sh in favor of github.com/karlkfi/intemp (intemp.sh)
- Refactor bash code to use intemp (extract functions to scripts)
- Remove util-ssl.sh in favor of mesosphere/kubernetes-keygen
Implement a flag that defines the frequency at which a node's out of
disk condition can change its status. Use this flag to suspend out of
disk status changes in the time period specified by the flag, after
the status is changed once.
Set the flag to 0 in e2e tests so that we can predictably test out of
disk node condition.
Also, use util.Clock interface for all time related functionality in
the kubelet. Calling time functions in unversioned package or time
package such as unversioned.Now() or time.Now() makes it really hard
to test such code. It also makes the tests flaky and sometimes
unnecessarily slow due to time.Sleep() calls used to simulate the
time elapsed. So use util.Clock interface instead which can be faked
in the tests.
For AWS EBS, a volume can only be attached to a node in the same AZ.
The scheduler must therefore detect if a volume is being attached to a
pod, and ensure that the pod is scheduled on a node in the same AZ as
the volume.
So that the scheduler need not query the cloud provider every time, and
to support decoupled operation (e.g. bare metal) we tag the volume with
our placement labels. This is done automatically by means of an
admission controller on AWS when a PersistentVolume is created backed by
an EBS volume.
Support for tagging GCE PVs will follow.
Pods that specify a volume directly (i.e. without using a
PersistentVolumeClaim) will not currently be scheduled correctly (i.e.
they will be scheduled without zone-awareness).
To build the python image, BUILD_PYTHON_IMAGE should be set during make.
When the addon script is running, it will check if python is installed
on the machine, if not, it will use the python image that built previously.
- default the release to the value of latest_release instead of
the string 'latest_release'
- use curl -O when retrieving kubectl to write output to disk instead
of to the screen
