Extending Argo CD with Health Checks and Resource Actions
Talkat GitOpsCon North America 2024 · on Monday, 2024-04-15· at 14:05· Level 3 | Room 322 | Track 2·
summary
Extends Argo CD by adding Lua-based health checks and resource actions placed in argocd-cm, with a local dev loop using argocd CLI to run checks against YAML. Shows override PVC late-binding to healthy to avoid stalled sync waves and a subscription fix for OpenShift restart bug that changes degraded to healthy. Explains aggregation precedence (unknown > degraded > missing > progressing > suspended > healthy), and demos a resource action to trigger a compliance rescan and an external-secret resync; recommends disabling inapplicable actions.
