# Rallly Kubernetes Manifests
|
|
|
|
This directory contains base Kubernetes manifests to self-host Rallly. It separates configuration (ConfigMaps) from sensitive data (Secrets) and uses a StatefulSet for the PostgreSQL database.
|
|
|
|
## Prerequisites
|
|
|
|
- A Kubernetes cluster.
|
|
- `kubectl` configured to talk to your cluster.
|
|
- An Ingress Controller (e.g., NGINX) installed.
|
|
|
|
## Configuration
|
|
|
|
1. **Secrets (`secrets.yaml`):**
|
|
- **Important:** Do not commit the `secrets.yaml` file with real credentials to version control. Consider adding `secrets.yaml` to your `.gitignore` file to prevent accidental commits.
|
|
- Update `POSTGRES_PASSWORD` and `SECRET_PASSWORD` (use `openssl rand -hex 32` to generate).
|
|
- **Critical:** Ensure the password in `DATABASE_URL` matches `POSTGRES_PASSWORD`. Both must use the same value.
|
|
- **Format:** The `DATABASE_URL` format should look like this: `postgres://<user>:<password>@<postgres-service-name>:5432/<db-name>`.
|
|
|
|
2. **Config (`rallly-config.yaml`):**
|
|
- Update `NEXT_PUBLIC_BASE_URL` to match your domain.
|
|
- Configure your SMTP settings for emails.
|
|
|
|
3. **Ingress (`ingress.yaml`):**
|
|
- Change `host: rallly.example.com` to your actual domain.
|
|
- Ensure `ingressClassName` matches your cluster's controller (default is set to `nginx`).
|
|
- **TLS:** Create the TLS certificate Secret named `rallly-tls` or enable cert-manager (see comments in `ingress.yaml` for options).
|
|
|
|
## Deployment Order
|
|
|
|
Apply the manifests in the following order to ensure dependencies are met:
|
|
|
|
```bash
|
|
# 1. Apply Secrets and Config first
|
|
kubectl apply -f secrets.yaml
|
|
kubectl apply -f rallly-config.yaml
|
|
|
|
# 2. Apply Database (StatefulSet)
|
|
kubectl apply -f postgres.yaml
|
|
|
|
# Wait for database to be ready
|
|
kubectl wait --for=condition=ready pod -l app=postgres --timeout=300s
|
|
|
|
# 3. Apply Application (Deployment)
|
|
kubectl apply -f rallly.yaml
|
|
|
|
# 4. Apply Ingress
|
|
kubectl apply -f ingress.yaml
|
|
```
|
|
|
|
**Note:** If you update `secrets.yaml` or `rallly-config.yaml` _after_ deployment, you must restart the Rallly pods for changes to take effect:
|
|
|
|
```bash
|
|
kubectl rollout restart deployment rallly
|
|
```
|
|
|
|
This performs a **rolling restart**, so there will be no downtime. However, ensure the new configuration is valid; if pods fail to start, check the logs with `kubectl logs -f deployment/rallly`.
|
|
|
|
## Verification
|
|
|
|
Check that the pods are running:
|
|
|
|
```bash
|
|
kubectl get pods
|
|
```
|
|
|
|
The Postgres pod should show `1/1 Running` and the Rallly pod should eventually show `1/1 Running` once the liveness probe passes.
|
|
|
|
## Notes on Storage
|
|
|
|
The PostgreSQL StatefulSet requests a 1Gi PersistentVolume. Ensure your cluster has a default StorageClass configured, or update the `volumeClaimTemplates` in `postgres.yaml` to specify a StorageClass. If no StorageClass is available, the PersistentVolumeClaim will remain pending and the postgres pod will not start. Check your cluster's available StorageClasses with `kubectl get storageclass`.
|
|
|
|
## Notes on Backups
|
|
|
|
For production deployments, implement regular PostgreSQL backups. Consider using:
|
|
|
|
- Kubernetes-native backup tools (e.g., Velero)
|
|
- Scheduled pg_dump jobs within the cluster
|
|
- Cloud-provider managed backups (if using managed K8s)
|
|
|
|
Refer to your cluster provider's backup documentation for recommendations.
