Tools

Production

Argo CD supports several different ways in which Kubernetes manifests can be defined:

• Kustomize applications
• Helm charts
• OCI images
• A directory of YAML, JSON, or Jsonnet manifests.
• Any custom config management tool configured as a config management plugin

$ argocd app sync APPNAME --local /path/to/dir/
