GitOps uses Git as the single source of truth for declarative infrastructure and application configurations. ArgoCD automates the synchronization between your Git repositories and Kubernetes clusters, ensuring deployed state always matches committed state.
ArgoCD Architecture and Setup
ArgoCD runs as a set of controllers within your Kubernetes cluster, continuously monitoring Git repositories for changes. When a new commit is detected, ArgoCD compares the desired state in Git with the live state in the cluster and applies any differences.
Application definitions in ArgoCD specify the Git repository, branch, path, and target cluster for each deployment. Sync policies control whether changes are applied automatically or require manual approval, supporting both continuous deployment and staged rollout workflows.
The ArgoCD web UI provides real-time visualization of your application's resource tree, sync status, and health. Combined with Slack notifications and webhook integrations, your team maintains full visibility into every deployment event across all environments.
