Learning DevOps - Second Edition

By: Mikael Krief

Overview of this book

In the implementation of DevOps processes, the choice of tools is crucial to the sustainability of projects and collaboration between developers and ops. This book presents the different patterns and tools for provisioning and configuring an infrastructure in the cloud, covering mostly open source tools with a large community contribution, such as Terraform, Ansible, and Packer, which are assets for automation. This DevOps book will show you how to containerize your applications with Docker and Kubernetes and walk you through the construction of DevOps pipelines in Jenkins as well as Azure pipelines before covering the tools and importance of testing. You'll find a complete chapter on DevOps practices and tooling for open source projects before getting to grips with security integration in DevOps using Inspec, Hashicorp Vault, and Azure Secure DevOps kit. You'll also learn about the reduction of downtime with blue-green deployment and feature flags techniques before finally covering common DevOps best practices for all your projects. By the end of this book, you'll have built a solid foundation in DevOps and developed the skills necessary to enhance a traditional software delivery process using modern software delivery tools and techniques.

Deploying Docker Compose containers in ACI

We discussed ACI in the Deploying a container to ACI with a CI/CD pipeline section.

Now, we will learn how to execute containers with Docker Compose configuration in ACI to run a set of containers that are on the same application services.

For this lab, we will use the same Docker Compose configuration we learned in the Using Docker for running command-line tools section. The only difference is that the running port on the nginx service is 80 instead of 8080, which we used locally (because my port 80 is already used by another service).

For deploying containers on ACI, we will perform the following steps:

  1. Inside our Azure subscription, we will create a new resource group called rg-acicompose.
  2. Then, in the console terminal, run the following Docker command to log in to Azure:
    docker login azure

The execution of this command opens a window that allows us to authenticate ourselves to our Azure subscription.
