GitOps Methodology: A Framework for Infrastructure Automation

As cloud computing and containerization continues to grow more popular, a need for an efficient, secure, and scalable way to manage this infrastructure grows alongside it. As a result, GitOps provides a framework for infrastructure automation. It leverages the power of Git, the popular version control system, as the source of truth for defining the desired state of a system.

With GitOps, teams can focus on delivering new features and improvements, rather than spending time on manual and repetitive infrastructure management tasks.

What is the GitOps Methodology?

GitOps is a methodology that uses Git as the source of truth for defining the desired state of a system and for automating its deployment and management.

In GitOps, infrastructure definitions, such as application configurations, environment variables, and resource templates, are stored in a Git repository. Changes to the system are made by committing code to the repository. Then, automated processes are triggered to build, test, and deploy the changes to the live environment. This provides a clear, auditable, and version-controlled way to manage the infrastructure. It also helps ensure consistency, security, and reliability in the delivery and operation of applications.

The GitOps methodology emphasizes a continuous integration and continuous delivery (CI/CD) approach. It encourages collaboration and communication among teams, reducing the risk of manual errors and inconsistencies.

Establishing a GitOps Workflow

By setting up a GitOps workflow, organizations can improve efficiency, increase transparency, enhance security, and improve collaboration in managing their infrastructure. So, here’s how to establish a GitOps workflow at your organization:

Prerequisites and Tools

Before establishing a GitOps workflow, your organization needs to meet a few prerequisites and have access to a few key tools. This includes:

  • Git: A version control system for storing and managing the infrastructure definition in a Git repository.

  • Continuous Integration/Continuous Deployment (CI/CD) tools: Automation tools for the deployment and management of infrastructure, such as Jenkins, TravisCI, CircleCI, or GitLab CI/CD.

  • Kubernetes: A container orchestration platform commonly used to manage and deploy applications in a GitOps workflow.

  • Infrastructure as Code (IaC) tools: Tools for defining and managing infrastructure resources, such as Terraform, CloudFormation, or Ansible.

  • Monitoring and logging tools: Monitoring tools for the performance and health of the infrastructure, such as Prometheus, Grafana, or ELK Stack.

  • A Git repository hosting platform: A platform for hosting the Git repository, such as GitHub, GitLab, or Bitbucket.

  • Command line interface (CLI) tools: Tools for interacting with the infrastructure, such as kubectl or AWS CLI.

With these prerequisites in place, your organization can start creating a Git repository for infrastructure definitions.

Creating a Git Repository for Infrastructure Definitions

Your organization can create a Git repository for infrastructure definitions in your Git repository hosting platform with these four steps:

  1. Create a new repository: Create a new repository in the chosen platform and give it a descriptive name, such as "infrastructure-definitions".

  2. Define the infrastructure: Use your IaC tools to define the desired state of your infrastructure. This includes creating templates for resources such as compute instances, networks, storage, and databases.

  3. Commit and push the definitions to the repository: Add the infrastructure definitions to the Git repository and commit them to the master branch. Then push the changes to the remote repository on the hosting platform.

  4. Set up access control: Set up access control for the repository to ensure that only authorized users can make changes to the infrastructure definitions.

Automating Infrastructure Deployment and Management

By automating infrastructure deployment and management, you can ensure that your infrastructure is consistently and reliably deployed. The GitOps workflow also provides a centralized view of the infrastructure, making it easier to manage and troubleshoot any issues that may arise. You can automate infrastructure deployment and management in your GitOps workflow by following these steps:

  1. Set up a CI/CD pipeline: Set up a CI/CD pipeline using your Ci/CD tools. The pipeline should be triggered whenever changes are pushed to the Git repository.

  2. Implement Continuous Deployment: Use the CI/CD pipeline to continuously deploy changes to the infrastructure. This can be done by running IaC tools to provision and update resources based on the infrastructure definitions in the Git repository.

  3. Monitor and log infrastructure changes: Use your chosen monitoring and logging tools to monitor the performance and health of the infrastructure. This allows you to quickly identify and address any issues that may arise during the deployment process.

  4. Automate Rollbacks: Implement a rollback mechanism to automatically revert changes in case of failures or issues with the deployment. You can implement this with Git tags or branches to keep track of previous versions of the infrastructure definitions.

  5. Review changes before deployment: Implement a review process for changes made to the infrastructure definitions. You can use pull requests or code reviews to ensure that changes are approved by the relevant stakeholders before they are deployed to production.

Best Practices for Implementing GitOps

Implementing GitOps can seem overwhelming at first, but with the right culture, any organization can find success with GitOps. So, here are a few best practices for creating a smooth implementation of GitOps at your organization:

  • Collaboration and communication: Foster collaboration and communication between teams, including developers, operations, and security teams. Encourage teams to work together to achieve a common goal of delivering high-quality infrastructure.

  • Embrace DevOps culture: Embrace a DevOps culture where development and operations teams work together to deliver high-quality infrastructure.

  • Empower teams: Empower teams to make decisions and take ownership of their work.

  • Continuous improvement: Encourage continuous improvement by regularly reviewing and refining the GitOps process.

  • Educate and train: Educate and train teams on the GitOps methodology and best practices. Offer training sessions, finance certification courses, or provide a structure for regular employee education.

  • Foster a culture of trust: Foster a culture of trust where teams trust each other to follow the established GitOps process.


The GitOps methodology is a powerful framework for automating infrastructure deployment and management. By using Git as the source of truth for the desired state of the infrastructure, teams can ensure that changes are made consistently and reliably. The use of pull requests and code reviews, as well as automation of the deployment pipeline, help ensure that changes are approved and made safely. Whether you are just starting to adopt GitOps or are looking to optimize your existing implementation, the GitOps methodology is a valuable tool for achieving infrastructure automation success.
