controller-manager in k8sm:
- rename host_port_endpoints flag to host-port-endpoints
- host port mapping strategy in scheduler should be driven by host-port-endpoints flag
- added host-port-endpoints to known flags
- docs: scheduler should also be configured with host-port-endpoints
- task recovery: be explicit about excluding mirror pods
- add busybox static pod to mesos-docker cluster
- customize static pods with binding annotations
- code cleanup
- removed hacky podtask.And func; support minimal resources for static pods when resource accounting is disabled
- removed zip archive of static pods, changed to gzip of PodList json
- pod utilities moved to package podutil
- added e2e test
- merge watched mirror pods into the mesos pod config stream
This patch
- set limits (0.25 cpu, 64 MB) on containers which are not limited in pod spec
(these are also passed to the kubelet such that it uses them for the docker
run limits)
- sums up the container resource limits for cpu and memory inside a pod,
- compares the sums to the offered resources
- puts the sums into the Mesos TaskInfo such that Mesos does the accounting
for the pod.
- parses the static pod spec and adds up the resources
- sets the executor resources to 0.25 cpu, 64 MB plus the static pod resources
- sets the cgroups in the kubelet for system containers, resource containers
and docker to the one of the executor that Mesos assigned
- adds scheduler parameters --default-container-cpu-limit and
--default-container-mem-limit.
The containers themselves are resource limited the Docker resource limit which
the kubelet applies when launching them.
Fixesmesosphere/kubernetes-mesos#68 and mesosphere/kubernetes-mesos#304
- the mesos scheduler gets a --static-pods-config parameter with a directory with
pods specs. They are zipped and sent over to newly started mesos executors.
- the mesos executor receives the zipper static pod config via ExecutorInfo.Data
and starts up the pods via the kubelet FileSource mechanism.
- both - the scheduler and the executor side - are fully unit tested
