This PR fixes Helm deployment failures caused by unquoted values in various ConfigMap templates.
Without quotes, YAML rendering could break when values (e.g., passwords, URIs, service URLs) contain special characters like @, :, or /, or when values were misinterpreted as non-strings.
Changes Made
Added | quote filters (and printf "%s:%s" where needed) to ensure all .Values references render as valid string literals.
Files Updated:
deploy/helm/templates/chatbot/config.yaml
deploy/helm/templates/community/config.yaml
deploy/helm/templates/identity/config.yaml
deploy/helm/templates/mailhog/config.yaml
deploy/helm/templates/web/config.yaml
Fixes include:
Quoting database credentials, ports, and URLs.
Properly quoting concatenated service endpoints (service:port) using printf.
Ensuring consistent YAML string rendering across all Helm templates.
Impact
Helm templates now render valid YAML even when credentials or URLs contain special characters.
helm upgrade --install works reliably with custom values.yaml.
No functional logic changes — only template rendering improvements.
Testing
Verified templates render correctly using:
helm template ./deploy/helm -f ./deploy/helm/values.yaml > rendered.yaml
kubectl apply -f rendered.yaml --dry-run=client
Confirmed successful CrAPI deployment on Kubernetes 1.30 / Helm 3.15.
