If you are not sure how to launch an ECS instance in Alibaba Cloud, refer to this documentation. To follow this tutorial, you will need to have Alibaba Cloud Elastic Compute Service (ECS) instances. Extending this diagram, we are going to create playbooks that will manage different users with their sudoers privilege in the target node. The diagram shows an Ansible controller node managing various nodes using SSH protocol. We will start by defining the architecture, as shown in the diagram below. In this article, we will learn how to manage users using Ansible in an Alibaba Cloud environment. Tech Share is Alibaba Cloud's incentive program to encourage the sharing of technical knowledge and best practices within the cloud community.
