about this book
With Road to Kubernetes, we start with creating simple Python and Node.js web applications. These applications will stay with us for our entire journey so we can learn about all the various tools and techniques to deploy them. From there, we start using secure shells (SSH) and modern version control by way of Git with self-managed environments, self-managed repositories, and self-managed deployments.
After we understand the self-managed way of deploying, we move to automation with GitHub, GitHub Actions, and even Ansible. GitHub is a popular third-party-managed git repository and code hosting service that also allows us to run one-off code workflows called GitHub Actions. These workflows are short-lived computing environments that are useful to build, test, and deploy our code and help us to continuously integrate and deliver (CI/CD) our apps. Ansible helps us automatically configure our deployment environments (e.g., virtual machines) by declaring what software we need to run our applications.
