reading time:
As platform engineers, we’ve witnessed how the infrastructure management landscape has dramatically transformed over the years. From the days of traditional operations, where manual configurations were the norm, it’s evolved into a realm where automation and collaboration are not just buzzwords but necessities.
The advent of DevOps introduced a paradigm shift by promoting a synergy between development and operations teams. Automation started to replace manual tasks, and the adoption of infrastructure as code (IaC) became more widespread. Tools like Puppet and Chef allowed us to define our infrastructure declaratively, reducing errors and increasing efficiency.
However, as our systems grew more complex, even IaC practices needed an upgrade. This is where GitOps emerged as the next evolutionary step. GitOps applies the principles of declarative infrastructure and enables us to manage complex systems more efficiently. By leveraging version control systems like Git, we can manage our infrastructure to ensure consistency, transparency, and reliability.
This blog post will explore GitOps’ foundational principles, essential components, and the advantages it offers to platform engineering. We’ll also discuss the challenges of adopting GitOps and how tools like Incredibuild can support GitOps workflows.
GitOps leverages Git to improve the management of declarative infrastructure/applications by integrating version control with automated deployment pipelines.
GitOps follows a few core principles that enhance the way we manage and deploy infrastructure:
By adhering to these principles, you can achieve a more efficient and reliable continuous deployment workflow, enhancing the overall agility of your development processes.
To effectively leverage GitOps in your platform engineering practices, you’ll need to understand its primary components.
Git is the backbone of GitOps, serving as the repository for all infrastructure code and configurations. It provides a single source of truth that enables version control, collaboration, and traceability for all changes made to the system with the following key features:
Defining infrastructure in a declarative manner is a cornerstone of GitOps. This involves Kubernetes manifests and custom resource definitions (CRDs). Using YAML or JSON files, we define the desired state of our Kubernetes clusters, including deployments, services, and other resources, making the infrastructure self-documenting and easier to manage.
Meanwhile, infrastructure-as-code tools like Terraform and Pulumi enable us to manage infrastructure declaratively for non-Kubernetes resources. These solutions let us define cloud resources, networking, and more, all through code that can be version-controlled.
Automating deployments is essential for achieving the speed and reliability that GitOps promises.
For example, By integrating CI/CD tools like Jenkins, GitLab CI/CD, or GitHub Actions, you can automate the deployment process. These solutions listen for changes in the Git repositories and trigger pipelines that build, test, and deploy code.
Pipeline as code is also key. Defining pipeline configurations in code ensures consistency and versioning. This means that any changes to the pipeline itself are tracked in Git, providing transparency and the ability to revert if necessary.
Keeping an eye on your system’s health is vital for proactive issue resolution. For this you will need:
GitOps will transform how you handle declarative infrastructure and continuous deployment through enhanced collaboration, reliability, security, and efficiency.
GitOps bridges the gap between dev and ops teams, resulting in highly improved collaboration.
The resulting unified processes via shared workflows and tools reduce miscommunication and streamline deployments. Both teams work from the same repositories and follow the same procedures, leading to better coordination.
Better collaboration also brings enhanced visibility. Transparent change logs improve accountability and knowledge sharing. Any changes made, who made them, and why are visible to everyone, promoting a culture of openness and trust.
GitOps promotes practices that enhance the stability of our systems.
When you treat infrastructure as immutable, you eliminate “works on my machine” issues. Consistency is maintained across development, staging, and production environments, minimizing unexpected issues.
With automated rollbacks and roll-forwards, quick recovery from failures is possible by reverting immediately to previous stable states. With version control in place, reverting to a previous state is as straightforward as undoing a commit.
Security is integral to GitOps, with built-in mechanisms for maintaining compliance and enabling auditability. Detailed records mean each change is logged, creating a transparent and traceable audit trail.
Policy as code is also key. Integrating security policies directly into code with tools like Open Policy Agent (OPA) facilitates automated and consistent enforcement across every deployment.
GitOps enables you to respond to issues more rapidly. With automated disaster recovery (DR), infrastructure can be redeployed rapidly in case of failures. Since everything is defined in code, rebuilding environments is straightforward.
You also benefit from continuous reconciliation. Immediate detection and correction of drift from the desired state keep the system aligned with the defined configurations, reducing downtime.
To best leverage a GitOps workflow, you need to understand the steps required to implement it effectively:
This workflow emphasizes automation and collaboration, streamlining the journey from code updates to deployment.
In addition, implementing GitOps effectively requires adherence to certain best practices:
By following these practices, you can reach the full potential of GitOps and enhance your platform engineering processes.
When implementing GitOps, choosing the right tools is crucial. The table below gives an overview of some top options.

To make an informed decision as to which GitOps tool aligns best with your needs, let’s explore critical factors for selection criteria:
While adopting GitOps brings significant benefits to platform engineering, it also presents several challenges we must consider carefully.
Firstly, a cultural shift is often required. Moving from manual interventions to trusting automated systems means embracing a new mindset. Breaking down silos between teams encourages cross-functional collaboration, aligning with DevOps principles and enhancing overall efficiency.
Secondly, the complexity of new tooling can be a hurdle. Seamlessly incorporating new tools into established systems requires thoughtful planning to prevent potential compatibility challenges.
Teams must invest time in onboarding and training to become proficient with these tools, ensuring everyone can work within the GitOps framework. This is essential for successfully implementing infrastructure-as-code practices central to modern platform engineering.
Security concerns are another critical consideration. Improper management of configurations in Git repositories can unintentionally expose sensitive information. Implementing robust secrets management and strict access controls, such as role-based access control (RBAC) policies, is imperative to safeguard the system.
Additionally, ensuring compliance with regulatory requirements, especially when managing declarative infrastructure across different geographical locations, adds complexity that must be addressed.
