# TCP Proxy

> Expose workloads over raw TCP using DCDeploy’s managed proxy.

DCDeploy supports **TCP proxies** for workloads that require raw TCP connections\
(e.g., databases, custom services, or non-HTTP protocols).

***

## When to Use

* Running PostgreSQL, MySQL, or other TCP-based services.
* Exposing internal tools that don’t use HTTP.
* Secure external access to non-web workloads.

***

## Configuration

1. Go to **Deploy-tab → Add database**.
2. Enable **TCP Proxy**.
3. Select the port(s) you want exposed.
4. A public TCP endpoint will be provisioned.

***

## Example: PostgreSQL

```yaml theme={null}
services:
  mysql-db:
    engine: mysql:9
    ports:
      - "5432"
    proxy: true
```

### Result:

Public TCP URL → mysql://USERNAME:[PASSWORD@mysql-9myyqbqq9e.tcp-proxy-2212.dcdeploy.cloud](mailto:PASSWORD@mysql-9myyqbqq9e.tcp-proxy-2212.dcdeploy.cloud):30298/mysql-db

### Security Notes

* Always require authentication (databases, SSH).
* Restrict IP access using firewall rules if possible.
* Use TLS where supported.
