Merge pull request #44744 from yguo0905/ubuntu-gce-cluster-tests
Automatic merge from submit-queue Support running Ubuntu image on GCE **What this PR does / why we need it**: This PR (on top of #44629) contains the script changes for running Ubuntu image on GCE. **Special notes for your reviewer**: We made change in `gci/node.yaml` and `gci/master.yaml` to ensure that Kubernetes jobs can start automatically after reboot. This is not needed for GCI but required by Ubuntu. See https://github.com/kubernetes/kubernetes/pull/44744#discussion_r113105970 for details. With this change, Ubuntu could use the same provisioning scripts as GCI's. Ran e2e tests using the following command and all tests passed. ``` KUBE_GCE_NODE_IMAGE=ubuntu-gke-1604-xenial-v20170420-1 KUBE_GCE_NODE_PROJECT=ubuntu-os-gke-cloud KUBE_NODE_OS_DISTRIBUTION=ubuntu GINKGO_PARALLEL=y GINKGO_PARALLEL_NODES=30 go run hack/e2e.go -- -v --build --up --test --test_args="--ginkgo.skip=\[Slow\]|\[Serial\]|\[Disruptive\]|\[Flaky\]|\[Feature:.+\]" --down ``` Also tested manually for both GCI and Ubuntu images. **Release note**: `Support Ubuntu 16.04 image on GCE`
