ArgoCD
ArgoCD is the leading GitOps continuous delivery tool for Kubernetes, enabling declarative application delivery where the desired state of applications is defined in Git repositories and ArgoCD continuously reconciles the live cluster state to match. It's become the standard for GitOps-based Kubernetes deployments.
What is ArgoCD?
ArgoCD watches Git repositories containing Kubernetes manifests (raw YAML, Helm charts, or Kustomize overlays) and automatically synchronises the cluster state when repositories are updated. It provides a web UI and CLI for visualising application status, comparing live and desired states, managing rollbacks, and setting deployment policies. ArgoCD ApplicationSets enable managing many applications across multiple clusters programmatically.
Why ArgoCD matters for your career
GitOps with ArgoCD provides a complete audit trail of all production changes (they're Git commits), enables rollback to any previous state, and decouples deployment from CI pipelines — CI builds and tests code; GitOps deploys it. This separation of concerns is increasingly the industry best practice for Kubernetes deployments.
Career paths using ArgoCD
ArgoCD skills are sought for Platform Engineer, DevOps Engineer, SRE, and Cloud Engineer roles at companies with Kubernetes-based infrastructure. The CNCF ecosystem's embrace of GitOps makes ArgoCD knowledge broadly applicable.

Frequently asked questions
What is GitOps?▼
GitOps is an operational model where Git is the single source of truth for infrastructure and application state. Changes are made via Git commits and pull requests; automation (ArgoCD, Flux) reconciles the actual environment to match the declared state. It provides auditability, repeatability, and easy rollback.
ArgoCD vs. Flux — which GitOps tool should I use?▼
Both are CNCF-graduated GitOps tools. ArgoCD has a richer web UI for visualisation and is more widely adopted for application delivery. Flux is lighter-weight with stronger multi-tenancy support. ArgoCD is generally recommended for teams that value observability; Flux for those preferring a pure CLI/GitOps approach.
