What is GitOps?

GitOps is a modern framework that uses Git as the version control system to automate the process of code delivery, including infrastructure and application definition as code, and the deployment of changes and rollbacks.

The idea behind GitOps is to have the infrastructure, applications, and all related components declaratively defined in one or more Git repositories.

How can I get started with GitOps?

You can create a shared GitOps repository. The purpose of the repo will be:

• Store and manage code and configurations
• Automatically deploying code changes in IaC files

The GitOps Workflow

Management of Code

In this diagram you can see git managing Infrastructure Code, Application code and Configuration code.

CI

Any changes in either of the code base will trigger Continuous Integration. In the CI stage we can run tests on the new code. After success of tests and review(by team), we can merge the code.

CD

The Continuous deployment automatically releases the merge code from the repo to the Kubernetes cluster.

GitOps Operator

A key component of GitOps is the GitOps operator, which runs within one of the Kubernetes clusters.

GitOps operator continuously monitors and pulls changes from the Git repository and applies them within the cluster it is running.

If a developer merges new code to the application Git repo, there is a round of unit testing, and the application reads the Docker image and pushes it to the container repository.

Then, it updates the Kubernetes manifest within another Git repository. The Git operator identifies the difference between the desired state in the Git repo and the actual state in the cluster, pulls the changes, and implements them on K8s Pods.

How can GitOps help me?

1. Makes Work Easier and Less Error-Prone: It simplifies the process of developing and deploying applications by using Git as a single source for all configurations and code. This means less confusion, fewer mistakes, and better organization for everyone.
2. Helps Teams Work Together: It helps different teams work together more smoothly by coordinating changes and solving problems faster.
3. Speeds Up Changes: It helps in quickly and efficiently rolling out changes to the applications.
4. Keeps Everything Consistent: It ensures that everything is consistent across different parts of the infrastructure, whether it’s in the cloud, on-premises, or in containers.
5. Saves Time and Money: By automating many tasks and reducing mistakes, it saves both time and money.
