When to use TCP Proxy?
- Databases – Expose PostgreSQL, MySQL, or Mongodb for internal/external access.
- Message Brokers – Kafka, RabbitMQ, or custom TCP services.
- Custom Protocols – Any app or service that doesn’t use HTTP/HTTPS.
Example: Mongo-db with TCP Proxy
TCP Public URLs for Databases
When you set protocol: tcp, DCDeploy provisions a public TCP endpoint so you can connect to your database or TCP service from anywhere.PostgreSQL Example
Best practices
- Secure your database – Never leave databases open without authentication. Always set strong passwords.
- Restrict access – Use firewall rules or allow-list IPs if possible.
- Prefer private networking – For production workloads, use DCDeploy’s private VPC or service-to-service networking instead of exposing databases publicly.
- Use secrets to store credentials rather than hardcoding them in your worhload form.
