Argo Workflows RBAC Quick Fix - Access Control Errors

Argo Workflows RBAC controls user permissions for workflow operations. Incorrect RBAC policies prevent users from submitting or viewing workflows. This guide covers the fix.

Quick Fix

Wrong

apiVersion: v1
kind: ConfigMap
metadata:
  name: argo-rbac-config
data:
  policy.csv: |
    p, role:developer, workflows, create, *, allow

The issue: missing g (group mapping) lines, no namespace restriction, and no get permission. Developers can create but not list or view workflows.

Right

apiVersion: v1
kind: ConfigMap
metadata:
  name: argo-rbac-config
data:
  policy.csv: |
    p, role:developer, workflows, create, default/*, allow
    p, role:developer, workflows, get, default/*, allow
    p, role:developer, workflows, list, default/*, allow
    g, alice@example.com, role:developer
    g, dev-team, role:developer

# Expected output after applying the fix
# Developer can create, get, and list workflows in default namespace
# RBAC enforced via SSO or basic auth
# Unauthorized operations return 403 Forbidden
# Audit logs show user identity for each operation

Prevention

• Define both permissions (p) and group mappings (g) in policy
• Use namespace-scoped permissions: default/* or */*
• Include get and list permissions alongside create
• Test RBAC policies with argo auth can-i
• Use groups from SSO provider for scalable permission management
