Argo CD
What it is
Argo CD is a free, open-source tool for delivering applications to Kubernetes using a GitOps workflow. It treats Git repositories as the source of truth for the desired state, then compares that state with what is running, displays differences, and can synchronize changes automatically or manually. It supports Kustomize, Helm, Jsonnet, YAML and JSON manifests, plus configured custom configuration tools, and can deploy to multiple Kubernetes clusters. A web interface shows application activity, while a command-line interface supports automation and CI integration. Access controls include multi-tenancy and role-based permissions, with single sign-on integrations such as OIDC, OAuth2, LDAP, SAML 2.0, GitHub, GitLab, Microsoft, and LinkedIn. Argo CD also provides access tokens, audit trails, and Prometheus metrics. Its free plan is free for a self-managed installation. Local accounts lack features such as groups and login history; the documentation recommends SSO when those are needed. A non-high-availability installation is not recommended for production use.
For and against
For
- Supports multiple Kubernetes deployment targets.
- Can compare and synchronize live and desired state.
- Works with Helm, Kustomize, Jsonnet, YAML, and JSON.
- Offers role-based access and single sign-on integrations.
- Provides audit trails and Prometheus metrics.
Against
- Local accounts lack groups and login history.
- Non-high-availability installation is not recommended for production.
- Self-managed installation requires operating it yourself.
The verdict
Argo CD combines Git-based deployment with state comparison, synchronization, and multi-cluster management. Teams should account for its self-managed setup and choose SSO if they need advanced local-account features.
Who it suits
Argo CD suits teams deploying applications to Kubernetes clusters from Git-managed configuration. Its common multi-tenant setup is used by multiple application developer teams and maintained by a platform team.
