Our team is struggling with manual configuration drifts in our EKS environment. We want to adopt a <DevOps & SRE> approach using Git as the single source of truth. What are the best tools and workflows to ensure our infrastructure stays synced with our repository without manual intervention?

Adopting GitOps is a transformative step for any reliability team. I highly recommend using ArgoCD for its robust visual interface and ease of integration with existing CI/CD pipelines. The core principle is to have a controller running inside your cluster that constantly compares the live state with your desired state in Git. When a discrepancy is detected, the controller automatically applies the changes. This not only eliminates manual errors but also provides a clear audit trail for every change made to your environment, making rollbacks as simple as reverting a commit in your repository.
This sounds great for fresh deployments, but how do we handle secrets like API keys and database passwords within a GitOps workflow without exposing them in plain text in our public or private repositories?
Flux is another fantastic CNCF graduated project for this. It is lightweight and follows a very modular design that fits perfectly into a microservices architecture.
I agree, Brenda. Flux’s multi-tenancy support is particularly useful for large organizations where different teams need to manage their own namespaces independently.
Joshua, that is a critical concern. You should look into Bitnami’s Sealed Secrets or integrate a vault provider like HashiCorp Vault. These tools allow you to store encrypted versions of your secrets in Git, which only the controller inside your cluster can decrypt, ensuring your sensitive data remains protected throughout the automation process.
