-# stuttgart-things/crossplane/postgres-server
+# Postgres Server (Crossplane Dev)
+
+A concise Crossplane configuration for a `PostgresServer` claim: it includes the XRD (CompositeResourceDefinition), a Composition (e.g., via provider-helm), and an example claim.
+
+## Overview
+- XRD/Definition: apis/definition.yaml
+- Composition: apis/composition.yaml
+- Claim example: examples/claim.yaml
+- Functions/Pipeline: examples/functions.yaml
+- Configuration metadata: crossplane.yaml
+
+## Prerequisites
+- Crossplane installed on the target cluster
+- provider-helm and (if used) provider-kubernetes installed and configured
+- kubectl access to the Crossplane cluster
+- Namespace for database workloads, e.g., postgres
+
+## Quickstart
+1. Render locally (validate pipeline):
+```bash
+crossplane render examples/claim.yaml \
+  apis/composition.yaml \
+  examples/functions.yaml \
+  --include-function-results
+```
+
+2. Create the app credentials Secret in the target namespace (make sure your claim uses the same namespace):
+```bash
+kubectl -n postgres apply -f - <<'EOF'
+apiVersion: v1
+kind: Secret
+metadata:
+  name: postgres-app-credentials
+type: Opaque
+stringData:
+  postgres-password: supersecret
+EOF
+```
+
+3. Apply the claim:
+```bash
+kubectl apply -f examples/claim.yaml
+```
+
+4. Verify Helm release (via provider-helm):
+```bash
+kubectl get releases.helm.m.crossplane.io -A
+kubectl describe releases.helm.m.crossplane.io my-postgres-d499897318cc
+```
+
+5. Inspect Crossplane resources:
+```bash
+kubectl get composite -A | grep -i postgres
+kubectl get xr -A | grep -i postgres
+kubectl get claim -A | grep -i PostgresServer
+```
+
+## Troubleshooting
+- Namespace mismatch: Ensure the claim uses the same namespace as your Secrets/workloads (e.g., postgres).
+- Missing Secret: postgres-app-credentials must exist before provisioning (or be optional in the chart/composition).
+- Helm CRD ownership conflicts: Stale CRDs/owner annotations can cause conflicts; remove/update safely.
+- Provider config: provider-helm must have access to the target cluster/namespace.
+
+## Cleanup
+```bash
+kubectl delete -f examples/claim.yaml
+kubectl -n postgres delete secret postgres-app-credentials
+```
