GitOps is a methodology for deploying and managing applications and infrastructure using Git as a single source of truth. It involves using Git to store and version the desired state of an application or infrastructure and using automation tools to ensure that the actual state matches the desired state. This allows for easy collaboration, rollbacks, and auditing, as well as the ability to use standard Git workflows for managing changes.
GitOps and DevOps are related yet distinct concepts
GitOps and DevOps are related yet distinct concepts. DevOps is a culture, practice, and a set of tools for building and delivering software quickly and reliably. It emphasizes collaboration between development and operations teams to automate the build, test, and deployment of software.
GitOps is a specific approach to implementing DevOps that uses Git as the single source of truth for both application and infrastructure code. It relies on Git-based workflow and automation tools to ensure that the desired state of the infrastructure and applications matches the actual state.
The specific aim of GitOPs and DevOps is speed — and to deliver reliability.
Both GitOps and DevOps aim to increase the speed and reliability of software delivery. However, GitOps emphasizes the use of Git as the central point of collaboration and control, while DevOps is more focused on the overall culture and practices of the organization.
How Do Teams Put GitOps Into Practice?
Teams can put GitOps into practice by following these general steps:
- Store all application and infrastructure code in a Git repository: This includes configuration files, scripts, and other files needed to deploy and manage the application and its dependencies.
- Use automation tools to deploy and manage the application: These tools can be used to ensure that the actual state of the application and infrastructure matches the desired state stored in Git. Examples include Kubernetes, Ansible, and Terraform.
