Setup SSL/TLS for PostgreSQL with Docker
- Setting up transport layer security (TLS) for PostgreSQL in production is crucial to prevent man-in-the-middle attacks.
- The guide focuses on connecting securely to the PostgreSQL database with a local certificate authority and enforcing encrypted connections with strict settings.
- Prerequisites include having Docker installed and running on the machine.
- Steps involve generating a certificate authority (CA), creating server and client certificate files, setting up TLS in PostgreSQL with an initialization script, building a Docker image with TLS enabled, and testing the connection.
- Deploying PostgreSQL with TLS on Sliplane involves creating a GitHub repository, logging in to Sliplane, deploying a server, choosing repository as deploy source, creating certificates, and adding environment variables for successful deployment.
- The tutorial concludes with accessing the PostgreSQL instance via a secure connection using psql client.
- Environmental variables required include POSTGRES_PASSWORD, SERVER_CERT, SERVER_KEY, and ROOT_CA_CRT.
- The tutorial provides detailed steps and scripts to enable SSL/TLS for PostgreSQL within a Docker environment.
- Ensure all generated certificate files are treated as secrets and not added to version control or Docker images.
- Overall, the tutorial offers a comprehensive guide for implementing SSL/TLS for PostgreSQL with Docker and ensuring secure database connections.
