Reconciliation

Understanding ArgoCD Reconciliation: How It Works, Why It Matters, and Best Practices

ArgoCD is a powerful GitOps controller for Kubernetes, enabling declarative configuration and automated synchronization of workloads. One of its core functions is reconciliation, a continuous process by which ArgoCD ensures that the live state of a Kubernetes cluster matches the desired state defined in a Git repository.

While this might sound straightforward, reconciliation plays a critical role in the GitOps lifecycle, and its default behavior can be surprisingly aggressive. In this blog post, we’ll explore:

  • What reconciliation in ArgoCD actually does
  • Why it exists and how it ensures cluster integrity
  • The pitfalls of the default timer
  • Best practices for tuning reconciliation to balance responsiveness and resource efficiency
