  Ansible Ansible is an open-source software provisioning, configuration management, and application-deployment tool enabling infrastructure as code. It runs on many Unix-like systems, and can configure both Unix-like systems as well as Microsoft Windows. Docker Docker is a software platform for building applications based on  containers  — small and lightweight execution environments that make shared use of the operating system kernel but otherwise run in isolation from one another.  Containers , by contrast, isolate applications’ execution environments from one another, but share the underlying OS kernel. They’re typically measured in megabytes, use far fewer resources than VMs, and start up almost immediately. Objectives: To write an Ansible PlayBook that does the following operations in the managed nodes: Configure Docker Start and enable Docker services Pull the httpd server image from the Docker Hub Run the docker container and expose it to the public Copy the ...
