Overview of this book

Ansible has a large collection of inbuilt modules to manage various cloud resources. The book begins with the concepts needed to safeguard your credentials and explain how you interact with cloud providers to manage resources. Each chapter begins with an introduction and prerequisites to use the right modules to manage a given cloud provider. Learn about Amazon Web Services, Google Cloud, Microsoft Azure, and other providers. Each chapter shows you how to create basic computing resources, which you can then use to deploy an application. Finally, you will be able to deploy a sample application to demonstrate various usage patterns and utilities of resources.

Running a container

In this recipe, we will be deploying a basic container using Ansible module's docker_container. Before we jump into creating a task, however, we should look at the following concepts, which are required to understand Docker containers:

  • Docker images: A Docker image is a read-only template that consists of all the dependencies necessary to run a piece of code. A container is actually a runtime instance of a Docker image.
  • Docker Hub: Docker Hub is the official repository of Docker images. Docker images created by organizations and the wider community are available on Docker Hub for general public use.

We will be using an Ubuntu image to create a Docker container. The docker_container module will download the image from Docker Hub and run the container.
