Introduction to GitOps

What is GitOps?

GitOps adds management of systems and apps to Git's version control. It only trusts Git repositories as the truth when it comes to setups. GitOps automated deployment, ensuring the system matches the Git repository state.


History and Origins of GitOps

The Beginning - Git and DevOps

  • Git: Created by Linus Torvalds in 2005, Git is a version control system. It's like a digital notebook that keeps track of every change made to the code, allowing developers to go back and see or revert any change they made.

  • DevOps: DevOps is a set of techniques that bring together the two fields of software development (Dev) and IT operations (Ops). The goal is to cut down on the time it takes to build a system and make sure that high-quality software is delivered all the time.


The Birth of GitOps

  • Weaveworks: A company called Weaveworks coined the term "GitOps" in 2017. Weaveworks specializes in cloud computing and managing software deployments.

  • Infrastructure as Code (IaC): Before GitOps, there was an idea called "Infrastructure as Code." This means that computer data centers are managed and set up using machine-readable definition files instead of real hardware configuration or interactive configuration tools. IaC set the stage for GitOps by stressing the need to write down in code what the ideal state of infrastructure should be.


Principles of GitOps

Declarative Configuration

GitOps relies heavily on declarative configuration. This concept requires that the desired state of the system be expressed using declarative code, often in YAML or JSON format. Declarative configuration enables unambiguous, versioned, and repeatable definitions of the infrastructure and applications.


Version Control

GitOps uses Git for version control, to keep track of all changes made to apps and infrastructure. This makes a single source of truth that teams can use to undo changes, check the past, and talk to each other better.



Automation is a core principle of GitOps. GitOps automates the deployment process using CI/CD pipelines. It lowers human intervention, mistakes, and speeds the delivery cycle. Automated procedures check the Git repository for updates and initiate deployments appropriately.


Immutable Infrastructure

GitOps advocates for immutable infrastructure, which means that infrastructure components don't change after deployment. Instead, updates are implemented by deploying new instances of the infrastructure. This strategy provides consistency, repeatability, and easy rollback in the event of failure.



GitOps focuses on observability to ensure system dependability. This entails regularly checking the system's status to ensure it corresponds to the desired state in the Git repository. Observability tools make it easier to track information about the system's health and performance.



Security is fundamental to GitOps. GitOps enhances deployment security using Git's version control, access controls, and audit logs. It ensures only authorized changes are implemented, and all changes are traceable and reversible.


GitOps Workflow

Git Repository

The Git repository is the foundation of the GitOps process. It contains declarative configuration files that specify the intended state of the infrastructure. This repository serves as the sole source of truth.


The CI/CD Pipeline

A strong CI/CD pipeline is critical for GitOps. It automates the process of creating, testing, and delivering changes. When a change is submitted to the Git repository, the CI/CD pipeline activates. After that it is validating and deploying the updated configuration.


Automated Deployments

GitOps ensures that the live system matches the desired state in the Git repository by automating deployments. Deployment tools continuously check the repository for updates. If there are any, it deploys them to the infrastructure and applications.


Validation & Rollback

Validation is an important stage in the GitOps workflow. Automated tests and validations verify that modifications do not cause bugs or vulnerabilities. In the event of a breakdown, GitOps includes tools for automatically rolling back to the prior stable state.


GitOps Best Practices

Use Declarative Configuration

Make sure that all infrastructure and application settings are stated declaratively. This technique encourages uniformity, repeatability, and ease of management. GitOps principles hinge on using declarative configuration for defining the desired state of the system.


Establish Strong CI/CD Pipelines

Create and manage a strong CI/CD pipeline to automate the build, test, and deployment processes. Make sure the pipelines incorporate automated validation processes to spot mistakes early. This is essential for adhering to GitOps best practices and ensuring efficient automated deployments.


Monitor and Observe

Implement thorough monitoring and observability tools to keep track of the system's status. Ensure that any deviation from the expected condition is identified and rectified immediately. Observability is crucial to the GitOps methodology, allowing teams to maintain system health and performance.


Safeguard Your Git Repository

Set rigorous access constraints for the Git repository. Make sure that only authorized individuals can make modifications, and that all changes are documented and auditable. This practice aligns with GitOps principles and helps secure your version control system.


Test Thoroughly

Thoroughly test setups and deployments. Use automated tests to assess changes before they are implemented in the production environment. Following GitOps best practices and GitOps principles involves rigorous testing to ensure that deployments are reliable and error-free.


Document Processes

Make sure you fully document the GitOps procedures and workflows. Ensure that all team members understand the GitOps processes, tools, and responsibilities. Clear documentation supports the GitOps methodology by providing a reference for consistent practices.


Main Benefits for DevOps Teams and Organizations

Better Transparency and Visibility

GitOps makes it easy for teams to see all the changes that have been made and their impacts. This improves communication and understanding throughout the company. This openness makes it easier to spot possible problems early and solve them quickly.


Consistency Across Environments

GitOps makes sure that deployments are consistent across all environments by using Git as the only source of truth. This consistency lowers the chance of issues that are unique to the setting and makes troubleshooting easier.


Change Management

Pull requests are used to handle changes to infrastructure and applications. This makes change management organized and safe. This process makes it easier to review, approve, and keep track of changes.


Security and Access Control

GitOps uses Git's built-in access control to keep track of who can make changes. This makes security better by making sure that only authorized users can change settings. This lowers the chance that changes will be made without permission.


Better Monitoring and Observability

With constant monitoring tools built into the GitOps workflow, teams can keep a close eye on the health and performance of the system. This proactive monitoring helps keep the system reliable and makes spotting any problems faster.


Simplified Onboarding

The Git folder makes it easy for new team members to quickly understand how the system is set up and what its current state is. That way it is easier for new employees to get to work quickly.


Lower Operational Costs

GitOps makes deployments and upkeep faster and easier by automating many tasks that used to be done by hand. This lowers operating costs and frees up teams to work on bigger, more important projects.


Challenges and Considerations in Implementing GitOps

Tooling and Integration

Selecting the right tools and ensuring seamless integration with existing systems is crucial. GitOps relies heavily on CI/CD pipelines, version control systems, and automation tools. Ensuring that these components work nicely is vital for achieving the best outcomes of the GitOps approach.
