As an alternative way of using the Alibaba Cloud console, you can use REST API calls through aliyuncli to create the ECS instances and your cluster. Follow these steps to do so:

1. After you've configured your cluster options on your Alibaba Cloud console, click on Generate API request Parameters right under the Create button to generate POST request body content to be used with the aliyun CLI.
2. Save the content in a file. In our case, this file is called cscreate.json.
3. For an explanation of the additional parameters listed in this section, please refer to the Create a Kubernetes section at https://www.alibabacloud.com/help/doc-detail/87525.htm.
4. Use the following command to create your cluster:

$ aliyun cs POST /clusters --header "Content-Type=application/json" 
--body "$(cat cscreate.json)"

The Alibaba Cloud Container Service provides two network plugin options for their Kubernetes clusters: Terway and Flannel.

Flannel is based on the community Flannel CNI plugin. Flannel is a very common and stable networking plugin that provides basic networking functionality. It is the recommended option for most use cases, except it does not support the Kubernetes NetworkPolicy. Terway is a network plugin developed by Alibaba Cloud CS. It is fully compatible with Flannel. Terway can define access policies between containers based on the Kubernetes NetworkPolicy. Terway also supports bandwidth limiting for containers.
