GitOps is a methodology for managing the deployment of applications and infrastructure using Git and other similar tools. The term “GitOps” was coined by Weaveworks, a company that provides a platform for deploying and managing containerized applications.
At a high level, GitOps is based on the idea that the desired state of the application or infrastructure should be specified in a Git repository. This includes not only the code for the application, but also the configuration and deployment scripts, as well as any other related infrastructure, such as databases or load balancers.
Once the desired state has been defined in Git, a GitOps tool can be used to continuously monitor the repository for changes. When a change is detected, the tool will automatically update the running application or infrastructure to match the new desired state.
This approach has a number of benefits. First, it provides a clear and auditable record of all changes made to the application or infrastructure. Second, it enables a more streamlined and automated deployment process, as changes can be automatically applied without manual intervention. Finally, it promotes a culture of collaboration and transparency, as all changes are made through the Git repository and can be reviewed and approved by the team.
There are a number of tools available for implementing GitOps, including Weaveworks’ Flux and Argo CD. These tools provide a range of features, including automated deployment, rollbacks, and integration with other DevOps tools such as Kubernetes and Jenkins.
In conclusion, GitOps is a powerful methodology for managing the deployment of applications and infrastructure. By leveraging the power of Git and other DevOps tools, teams can automate and streamline their deployment processes, while also promoting collaboration and transparency across the organization.
