Summary

  • Update values examples (minimal and dev) with required workarounds for chart-managed PostgreSQL and OpenSearch
  • Add two new FAQ entries documenting the issues and solutions

Changes

The langwatch-helm chart v1.1.3 has two bugs that prevent successful installation:

  1. OpenSearch duplicate env var: The chart adds cluster.initial_master_nodes twice, causing Kubernetes to reject the StatefulSet. Fixed by adding singleNode: true.

  2. Missing Bitnami PostgreSQL images: The chart references Bitnami image tags that no longer exist on Docker Hub. Fixed by using bitnamilegacy/postgresql:16 and disabling volumePermissions.

Test plan

  • Verify the updated values examples work with a fresh minikube installation
  • Confirm FAQ entries render correctly in the docs
