DevOps Dictionary

Argo CD is a GitOps-based continuous delivery tool for deploying and managing applications on Kubernetes. It treats Git as the source of truth for the desired cluster state, then continuously compares what is running in the cluster to what is declared in Git and reconciles differences by syncing changes. This addresses the common problem of configuration drift, manual deployments, and inconsistent environments by making deployments auditable, repeatable, and easier to roll back using version control.

With Argo CD, teams get consistent, self-healing deployments where changes are reviewed and tracked in Git; without it, releases often rely on manual steps or imperative commands that are harder to audit and can leave clusters in an unknown state. This gap exists because Kubernetes is highly dynamic, and without a controller enforcing the declared state, small changes and ad hoc fixes accumulate over time.
