+# Quickstart
+
+This guide installs Supabase Operator and its PostgreSQL and object storage
+dependencies on a fresh Kubernetes cluster.
+
+The dependency manifests use local credentials for evaluation. Change every
+password before exposing any service outside the cluster.
+
+## Prerequisites
+
+1. Kubernetes 1.33 or later
+2. `kubectl`
+3. Helm
+4. A local copy of this repository
+
+Add the chart repositories:
+
+```sh
+helm repo add cnpg https://cloudnative-pg.github.io/charts
+helm repo add minio https://charts.min.io/
+helm repo add jetstack https://charts.jetstack.io
+helm repo add strrl https://helm.strrl.dev
+helm repo update cnpg minio jetstack strrl
+```
+
+## 1. Install CloudNativePG
+
+```sh
+helm upgrade --install cnpg cnpg/cloudnative-pg \
+  --namespace cnpg-system \
+  --create-namespace \
+  --version 0.29.0 \
+  --wait \
+  --timeout 5m
+
+kubectl apply -f docs/quickstart/postgres-cluster.yaml
+kubectl wait \
+  --namespace supabase-quickstart \
+  --for=condition=Ready \
+  cluster/supabase-postgres \
+  --timeout 10m
+```
+
+Expected result:
+
+```text
+cluster.postgresql.cnpg.io/supabase-postgres condition met
+```
+
+The checked in Cluster manifest uses `supabase/postgres`, UID `101`, GID
+`102`, and superuser access. These settings are required by the database
+initialization job.
+
+## 2. Install MinIO
+
+```sh
+helm upgrade --install minio minio/minio \
+  --namespace supabase-quickstart \
+  --create-namespace \
+  --version 5.4.0 \
+  --values docs/quickstart/minio/values.yaml \
+  --wait \
+  --timeout 5m
+
+kubectl rollout status deployment/minio \
+  --namespace supabase-quickstart \
+  --timeout 5m
+```
+
+Expected result:
+
+```text
+deployment "minio" successfully rolled out
+```
+
+The chart values create the `supabase-storage` bucket. Its name and
+credentials match `docs/quickstart/storage-secret.yaml`.
+
+## 3. Install cert-manager and Supabase Operator
+
+The operator webhook uses cert-manager.
+
+```sh
+helm upgrade --install cert-manager jetstack/cert-manager \
+  --namespace cert-manager \
+  --create-namespace \
+  --version v1.21.0 \
+  --set crds.enabled=true \
+  --wait \
+  --timeout 5m
+
+helm upgrade --install supabase-operator strrl/supabase-operator \
+  --namespace supabase-operator-system \
+  --create-namespace \
+  --version 2026.7.25 \
+  --wait \
+  --timeout 5m
+
+kubectl rollout status deployment/supabase-operator \
+  --namespace supabase-operator-system \
+  --timeout 5m
+```
+
+Expected result:
+
+```text
+deployment "supabase-operator" successfully rolled out
+```
+
+## 4. Create the credential Secrets
+
+```sh
+kubectl apply -f docs/quickstart/database-secret.yaml
+kubectl apply -f docs/quickstart/storage-secret.yaml
+kubectl apply -f docs/quickstart/studio-basic-auth-secret.yaml
+```
+
+Expected Secrets:
+
+```text
+supabase-db-credentials
+supabase-storage-credentials
+supabase-studio-basic-auth
+```
+
+Secret key names are part of the operator API contract. Do not rename
+`host`, `port`, `database`, `username`, `password`, `endpoint`, `region`,
+`bucket`, `accessKeyId`, or `secretAccessKey`.
+
+## 5. Create the SupabaseProject
+
+```sh
+kubectl apply -f docs/quickstart/supabase-project.yaml
+kubectl wait \
+  --namespace supabase-quickstart \
+  --for=jsonpath='{.status.phase}'=Running \
+  supabaseproject/quickstart \
+  --timeout 10m
+
+kubectl get supabaseproject quickstart \
+  --namespace supabase-quickstart
+```
+
+Expected result:
+
+```text
+NAME         PHASE
+quickstart   Running
+```
+
+The project uses `sslMode: require` for PostgreSQL and path style S3
+requests for MinIO.
+
+## 6. Open Studio
+
+Forward Kong in one terminal:
+
+```sh
+kubectl port-forward \
+  --namespace supabase-quickstart \
+  service/quickstart-kong \
+  18000:8000
+```
+
+Open <http://127.0.0.1:18000/> and enter:
+
+```text
+Username: supabase
+Password: quickstart-studio-password
+```
+
+The browser should load Supabase Studio. You can also check the response:
+
+```sh
+curl \
+  --user supabase:quickstart-studio-password \
+  --location \
+  --output /dev/null \
+  --silent \
+  --show-error \
+  --write-out 'HTTP %{http_code}\n' \
+  http://127.0.0.1:18000/
+```
+
+Expected result:
+
+```text
+HTTP 200
+```
+
+## Troubleshooting
+
+Check project status and operator logs:
+
+```sh
+kubectl get supabaseproject quickstart \
+  --namespace supabase-quickstart \
+  -o yaml
+
+kubectl logs deployment/supabase-operator \
+  --namespace supabase-operator-system
+```

+[`docs/quickstart/VALIDATION.md`](quickstart/VALIDATION.md).
