CI/CD has long been the standard for modern development teams. But how do you make sure that deployment automation doesn't turn into chaos? 🤯 Here comes to the rescue GitOps — an approach that allows you to manage infrastructure and applications through Git repositories.
GitOps is a practice where Git is the only source of truth for application and infrastructure configurations.
All changes are described in Git.
Specialized agents monitor the repository.
As soon as a new commit appears in Git, the configuration is automatically applied in the environment.
Thus, deploy = git push. ✨
Why is GitOps better than classic CI/CD?
🔧 Transparency — the entire history of changes is stored in Git.
🔧 Recovery — easily roll back to the desired commit.
🔧 Speed — developers simply update manifests.
🔧 Safety — management only through Git, without direct access to production.
GitOps Core Tools
ArgoCD — a popular solution for Kubernetes.
FluxCD — a lightweight tool with support for GitOps patterns.
Jenkins X — CI/CD with a focus on Kubernetes and GitOps.
What does the workflow look like?
The developer pushes the code and the updated manifest to Git.
The GitOps agent (for example, ArgoCD) notices the changes.
The agent synchronizes the cluster state with the one described in Git.
The application is expanded, the pipelines do not break. 🎉
Possible difficulties
❌ Entry threshold — you need to master Kubernetes and declarative manifests.
❌ Infrastructure — GitOps will not save you in the chaos of environments.
❌ Mental shift — configurations should live in Git, not in someone's terminal.
GitOps in the future
GitOps has already become the standard for the Kubernetes world, but its ideas go far beyond that. In the coming years, we will see GitOps approaches for clouds, microservices, and even IoT.
To master GitOps, it is important to have a solid base in development. In the application Code you can take courses in Python, JavaScript, Lua and other languages, get a certificate and apply your knowledge in practice. This is a great foundation to confidently move towards DevOps and GitOps approaches.
