# Lago Events Processing - Example Configurations
2+
3+
This directory contains example configurations for deploying Lago's events processing components.
4+
In this example, ClickHouse, Redpanda, Redis, and Postgres are deployed as standalone services within the Kubernetes cluster.
5+
This setup is intended solely for demonstration and testing purposes.
6+
**For any real-life or production use case, you must provision and host these dependencies in a production-ready manner**
7+
—using managed services or properly secured, highly available deployments—rather than relying on the example manifests provided here.
8+
9+
**Security Notice:**
10+
11+
The example manifests in this directory are for demonstration only.
12+
**TLS encryption and secure passwords are NOT enabled by default.**
13+
14+
- **TLS:** All external services (Postgres, Redis, ClickHouse, Redpanda) are deployed without TLS.
15+
- In production, you **must** enable TLS for all external services to protect data in transit.
16+
- Update the `values.yaml` and external manifests to enable and configure TLS certificates.
17+
- **Passwords:** Default credentials (e.g., `postgres:postgres`, `redis:default`) are insecure and should **never** be used in production.
18+
- Always set strong, unique passwords for all services.
19+
- Store secrets securely (e.g., in Kubernetes Secrets or a secret manager).
20+
- **ClickHouse & Kafka:** The example disables authentication and encryption.
21+
- Enable user authentication and configure secure connections for ClickHouse and Redpanda/Kafka.
22+
23+
**Before using in production:**
24+
- Review and update all manifests to enforce strong authentication and TLS.
25+
- Never expose these example services to the public internet.
26+
- Refer to the official documentation for secure deployment practices.
27+
28+
## Example Scenarios
29+
30+
### Complete Events Stack
31+
Deploy all external dependencies and the events processing components:
32+
33+
```bash
34+
# Deploy dependencies first
35+
kubectl apply -f external/postgres.yml -f external/redis.yml -f external/redpanda.yaml -f external/clickhouse.yaml
36+
37+
# Install the events processing chart
38+
helm install lago-events-example --values values.yaml ../../
39+
```
40+
41+
### Custom Configuration
42+
43+
You can mix and match these examples or create your own:
44+
45+
```bash
46+
# Use specific example values
47+
helm install lago-events-example --values values.yaml ../../
48+
49+
# Or combine multiple configurations
50+
helm install lago-events-example --values values.yaml --values custom.yaml ../../
51+
```
52+
53+
## Upgrading
54+
55+
Once installed, you can upgrade with new configurations:
56+
57+
```bash
58+
helm upgrade --values values.yaml --values custom.yaml lago ../../
59+
```
60+
61+
## Notes
62+
63+
- This is an **example repository** for demonstration purposes
64+
- For production deployments, refer to the official Lago documentation
65+
- Adjust resource limits and configurations based on your environment needs
