Automatic merge from submit-queue (batch tested with PRs 52227, 52120) Use COS for nodes in testing clusters by default, and bump COS. Addresses part of issue #51487. May assist with #51961 and #50695. CVM is being deprecated, and falls out of support on 2017/10/01. We shouldn't run test jobs on it. So start using COS for all test jobs. The default value of `KUBE_NODE_OS_DISTRIBUTION` for clusters created for testing will now be gci. Testjobs that do not specify this value will now run on clusters using COS (aka GCI) as the node OS, instead of CVM, the previous default. This change only affects testing; non-testing clusters already use COS by default. In addition, bump the version of COS from `cos-stable-60-9592-84-0` to `cos-stable-60-9592-90-0`. ```release-note NONE ``` /cc @yujuhong, @mtaufen, @fejta, @krzyzacy
Cluster Configuration
Deprecation Notice: This directory has entered maintenance mode and will not be accepting new providers. Please submit new automation deployments to kube-deploy. Deployments in this directory will continue to be maintained and supported at their current level of support.
The scripts and data in this directory automate creation and configuration of a Kubernetes cluster, including networking, DNS, nodes, and master components.
See the getting-started guides for examples of how to use the scripts.
cloudprovider/config-default.sh contains a set of tweakable definitions/parameters for the cluster.
The heavy lifting of configuring the VMs is done by SaltStack.
