argocd-applicationset-json-plugin

Helm chart for the argocd-applicationset-json-plugin — a generic ArgoCD ApplicationSet plugin that fetches JSON from a URL and applies JSONPath or jq filtering.

Install

helm install my-plugin . \
  --namespace argocd \
  --set plugin.url=https://example.com/data.json

End-to-end example

See examples/ for a battle-tested walkthrough that:

• installs the chart,
• verifies the plugin responds to the same call ArgoCD makes (see examples/test-plugin.sh),
• wires it up as an ApplicationSet generator (examples/applicationset-jsonpath.yaml, examples/applicationset-jq.yaml).

Plugin modes

plugin.mode selects which evaluator to enable: jsonpath (default), jq, or dual. The image tag in image.tag should match (jsonpath-1.0.0, jq-1.0.0, or dual-1.0.0).
