About the Book

This book teaches a technically inclined reader how to automate the deployment process of self-written software using Open Source tools. Thus it introduces you to Continuous Delivery, a practice under the DevOps umbrella. It enables faster feedback cycles, which is an important aspect of agile software development.

It makes some assumptions on the technologies used:

  • Debian GNU/Linux or derived distributions, such as Ubuntu, as the operating system
  • aptly for repository management
  • Ansible for deployment and configuration management
  • Go Continuous Delivery for orchestrating the process

It covers the following topics:

  • Why automate the release process?
  • Requirements for automated deployments
  • Deployments enviroments (test, staging, production, ...) and their function
  • Architecture of a deployment system
  • Packaging the software
  • Distributing the software
  • Deploying the software
  • Orchestrating the whole process with Go Continuous Delivery
  • Version handling
  • Unit Testing
  • Smoke Testing and Rolling Deployments
  • Security Considerations
  • State Management and managing schema changes.

It shows a step by step process for creating a deployment system, and features two example applications deployed this way.
