Implementing GitOps with Kubernetes

An Introduction to GitOps

In this opening chapter, we’ll delve into GitOps, an innovative approach that’s revolutionizing software development and operations. This chapter begins with the tale of GitOps, focusing on its transformative effect on organizational culture and workflows. The Fundamentals of GitOps section outlines its core principles, such as the centralization of Git, its declarative approach, and automated synchronization. Traditional CI/CD with DevOps against GitOps traces the evolution of software deployment, contextualizing GitOps in the broader history of the field. This chapter will also contrast traditional CI/CD and DevOps methodologies with GitOps, highlighting GitOps as an evolution in managing complex systems. We’ll conclude by discussing the advantages of adopting GitOps for platform engineering while illustrating its efficiency, consistency, and adaptability.

In this chapter, we’ll cover the following topics:

  • GitOps unveiled...

Technical requirements

To follow along with this chapter, you need to have basic knowledge of version control, Infrastructure as Code (IaC), continuous integration (CI), continuous delivery (CD), and Kubernetes. Basic knowledge of major cloud providers, such as Google Cloud Platform (GCP), AWS, and Azure, will be beneficial.

GitOps unveiled – reshaping development culture and practices

In the realm of modern software development and operations, GitOps emerges as a confluence of ideas and practices, redefining the approach to managing complex systems.

The term GitOps was first introduced by Alexis Richardson, the co-founder of Weaveworks, in August 2017 through a series of blog posts. Richardson described GitOps as a methodology where developer tools are pivotal in driving operational procedures. This approach emphasized the significance of using declarative tools and advocated for the best practices wherein configurations are treated as code. Consequently, these configurations should be subject to version control, aligning with the core principles of GitOps.

This innovative concept marked a shift in how software development and IT operations teams approach how infrastructure and applications are managed and deployed, promoting a more efficient, transparent, and reliable process.

GitOps...

The fundamentals of GitOps and the advantages of adopting it for platform engineering

DevOps emerged as a response to these silos, blending the roles of development and operations. It extended the principles of CI/CD to include a cultural shift toward collaboration, aiming to break down the barriers between developers and IT operations. The emphasis was on a holistic approach to the software life cycle, ensuring that both development and operational considerations were integrated from the start. DevOps embraced practices such as IaC and monitoring, fostering a more responsive and agile environment.

GitOps, a more recent innovation, builds upon these foundations but introduces a significant shift: it takes the principles of DevOps and CI/CD and centralizes them around the Git repository.

In a GitOps story, as illustrated in Figure 1.5, everything begins with a Git repository, where the entire state of a system – code, configuration, environment settings, and even documentation...

Why GitOps?

Adopting GitOps for platform engineering brings a multitude of advantages, reshaping how teams interact with infrastructure and applications. This methodology leverages the strengths of Git, automation, and declarative configurations, providing a robust framework for managing complex systems. Here are some of the key benefits:

  • Declarative and immutable nature: GitOps focuses on declaring the desired state of systems rather than detailing imperative scripts. It adopts an immutable infrastructure approach where changes are made by replacing resources rather than modifying existing ones, enhancing consistency and stability.
  • Automated synchronization: Central to GitOps is automatically synchronizing the system state with the configurations described in Git to cover the full life cycle of infrastructure and applications, including deployment, updates, scaling, and recovery.
  • Pull request workflow integration: Operational processes in GitOps are deeply integrated...

The integration between GitOps, IaC, and Kubernetes

In this section, we’ll delve into the intricate integration of GitOps, IaC, and Kubernetes, along with key tools such as Argo CD and Flux CD. We’ll explore how this cohesive blend enhances cloud-native operations, streamlining deployment processes and bolstering security, thereby revolutionizing the way infrastructure is managed and applications are deployed in modern software development environments.

GitOps and IaC

IaC involves managing and provisioning infrastructure via code rather than manual procedures. This approach involves creating configuration files that detail your infrastructure requirements, thus simplifying the process of modifying and disseminating these configurations. IaC guarantees consistent provisioning of the same environment each time, and at the same time, IaC transforms configuration specifications into coded documentation, improving configuration management.

This approach helps avoid...

Summary

This chapter provided an in-depth introduction to GitOps, exploring its transformative impact on software development and operations. We began by contrasting GitOps with traditional CI/CD and DevOps methodologies, highlighting its unique approach and advantages.

Then, we covered the history and evolution of deployment strategies that led to GitOps. Key principles such as Git centralization, the declarative approach, automated synchronization, and continuous feedback were discussed, emphasizing GitOps’ role in enhancing efficiency, consistency, and collaboration in platform engineering.

Additionally, we delved into GitOps’ integration with tools such as Kubernetes, showcasing its scalability and security advantages in modern cloud environments. We concluded by underscoring the significance of adopting GitOps for its robust framework and adaptability to evolving technological landscapes.

In Chapter 2, we’ll dive into the practicalities of GitOps...

The book introduces GitOps core concepts and principles and then delves into integrating version control and GitOps tools such as Argo CD, Flux CD, Helm, and Kustomize with Kubernetes. You’ll learn about scaling GitOps across multiple clusters, architectural designs for efficient cloud-native operations, and the cultural transformation needed to support GitOps adoption within an organization. As you progress, you’ll be able to automate infrastructure and implement CI/CD processes on OpenShift, MS Azure, and AWS platforms using GitOps, Terraform, OpenTofu, and Argo CD. You’ll also explore examples and best practices for integrating observability, enhancing security, managing financial operations (FinOps), and future trends such as AI and sustainability in GitOps. By the end of this book, you’ll have gained the skills you need to apply GitOps strategies for robust Kubernetes and cloud deployments, thereby boosting your productivity and efficiency.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
