- The e2e suite can be instructed not to wait for pods in kube-system to be ready or for all nodes to be ready by passing `--allowed-not-ready-nodes=-1` when invoking the e2e.test program. This allows callers to run subsets of the e2e suite in scenarios other than perfectly healthy clusters. ([#98781](https://github.com/kubernetes/kubernetes/pull/98781), [@smarterclay...

### Testing

- e2e storage tests now run faster and are easier to read ([#72434](https://github.com/kubernetes/kubernetes/pull/72434), [@pohly](https://github.com/pohly))

    *   histograms stored, one for each disk. (Did not aggregate well).
* Update kubernetes-e2e charm to use snaps ([#45044](https://github.com/kubernetes/kubernetes/pull/45044), [@Cynerva](https://github.com/Cynerva))
* Log the error (if any) in e2e metrics gathering step ([#45039](https://github.com/kubernetes/kubernetes/pull/45039), [@shyamjvs](https://github.com/shyamjvs))

* test/e2e/e2e.test: ([#69105](https://github.com/kubernetes/kubernetes/pull/69105), [@pohly](https://github.com/pohly))
   * -viper-config can be used to set also the options defined by command line flags

- Feature gate `ProbeTerminationGracePeriod` is enabled by default. ([#108541](https://github.com/kubernetes/kubernetes/pull/108541), [@kerthcet](https://github.com/kerthcet))

- The image `gcr.io/kubernetes-e2e-test-images` will no longer be used in E2E / CI testing, `k8s.gcr.io/e2e-test-images` will be used instead. ([#103724](https://github.com/kubernetes/kubernetes/pull/103724), [@claudiubelu](https://github.com/claudiubelu))

## Known Issues
- volumeDevices mapping ignored when container is privileged

  
      `kube-proxy --feature-gates NFTablesProxyMode=true --proxy-mode nftables`
  
  This is currently an alpha-level feature and while it probably will not
  eat your data, it may nibble at it a bit. (It passes e2e testing but has
  not yet seen real-world use.)
  
  At this point it should be functionally mostly identical to the iptables
  mode, except that it does not (and will not) support Service NodePorts on

- Skip [k8s.io/kubernetes@v1.19.0/test/e2e/storage/testsuites/base.go:162]: Driver azure-disk doesn't support snapshot type DynamicSnapshot -- skipping

    *   This release supports Kubernetes 1.9+ and containerd v1.0.0+.
    *   Pass all Kubernetes 1.9 e2e test, node e2e test and CRI validation tests.
    *   [Kube-up.sh integration](https://github.com/kubernetes-incubator/cri-containerd/blob/master/docs/kube-up.md).
