* Make DaemonSet respect critical pods annotation when scheduling. ([#42028](https://github.com/kubernetes/kubernetes/pull/42028), [@janetkuo](https://github.com/janetkuo))
* Implement the update feature for DaemonSet. ([#41116](https://github.com/kubernetes/kubernetes/pull/41116), [@lukaszo](https://github.com/lukaszo))

consequence, all volume mounts in containers are now `rslave` on Linux by default. To make this default work in all Linux environments the entire mount tree should be marked as shareable, e.g. via `mount --make-rshared /`. All Linux distributions that use systemd already have the root directory mounted as rshared and hence they need not do anything. In Linux environments without systemd we recommend running `mount --make-rshared /` during boot before docker is started, ([@jsafrane](https://github.com/jsafrane))...

[SIG Storage](https://github.com/kubernetes/community/tree/master/sig-storage) is responsible for storage and volume plugin components.

* Add node e2e tests for hostPid ([#44119](https://github.com/kubernetes/kubernetes/pull/44119), [@feiskyer](https://github.com/feiskyer))
* kubeadm: Make `kubeadm reset` tolerant of a disabled docker service. ([#43951](https://github.com/kubernetes/kubernetes/pull/43951), [@luxas](https://github.com/luxas))
* kubelet: make dockershim.sock configurable ([#43914](https://github.com/kubernetes/kubernetes/pull/43914), [@ncdc](https://github.com/ncdc))

  - `timeout` default changed from `30s` to `10s` for v1
  - `sideEffects` default value is removed, and the field made required, and only `None` and `NoneOnDryRun` are permitted for v1
  - `admissionReviewVersions` default value is removed and the field made required for v1 (supported versions for AdmissionReview are `v1` and `v1beta1`)

 Extended resources cannot be overcommitted, so make sure that request and limit are equal
 if both are present in a container spec.

 - The default Bootstrap Token created with `kubeadm init` v1.8 expires
 and is deleted after 24 hours by default to limit the exposure of the
 valuable credential. You can create a new Bootstrap Token with
 `kubeadm token create` or make the default token permanently valid by specifying

In 1.12, SIG Cluster lifecycle has focused on improving the user experience in kubeadm, by fixing a number of bugs and adding some new important features.

Here is a list of some of the changes that have been made to kubeadm:

- Kubeadm internal config has been promoted to `v1alpha3`:
  - `v1alpha1` has been removed.

- Kubeadm: make etcd pod request 100m CPU, 100Mi memory and 100Mi ephemeral_storage by default ([#94479](https://github.com/kubernetes/kubernetes/pull/94479), [@knight42](https://github.com/knight42)) [SIG Cluster Lifecycle]
- Kubeadm: make the command "kubeadm alpha kubeconfig user" accept a "--config" flag and remove the following flags:
