In peacetime operation and maintenance work sometimes need to be based on different remote nodes or different IP systems to do different configuration deployment. For example, ansible can do different processing of the configuration files on each node according to different IP addresses, and variables are needed here.You can define variables directly in the playbooks file:-Hosts:webservers vars:http_port:80A variable named Http_port is defined with a

Deploy containers using atomic hosts, Ansible, and CockpitGuideAn atomic host from an atomic project is a lightweight container operating system that can run Linux containers in Docker format. It is specially tailored to improve efficiency and makes it an ideal choice for the Docker runtime system used in the cloud environment.
We are lucky to find a good way to manage the containers running on the host: Cockpit. It is a GNU/Linux Server Remote Manage
