# Postgre-TLS - Secure PostgreSQL Docker Setup with SSL/TLS
|
||||
|
||||
A secure PostgreSQL Docker container with enforced SSL/TLS encryption, certificate verification, and advanced security features.
|
||||
|
||||
## Features
|
||||
|
||||
- **SSL/TLS Encryption**: TLSv1.3 with 256-bit AES-GCM encryption
|
||||
- **Certificate Verification**: Full SSL certificate verification enabled
|
||||
- **SCRAM-SHA-256 Authentication**: Secure password authentication
|
||||
- **Row-Level Security**: Built-in support for fine-grained access control
|
||||
- **Audit Logging**: Comprehensive audit trail for database operations
|
||||
- **Data Integrity**: Checksums enabled for data corruption detection
|
||||
- **Monitoring**: Built-in performance monitoring with pg_stat_statements
|
||||
- **Encryption Functions**: pgcrypto extension for additional encryption capabilities
|
||||
|
||||
## Quick Start
|
||||
|
||||
1. **Start the PostgreSQL container**:
|
||||
```bash
|
||||
./start.sh
|
||||
```
|
||||
|
||||
2. **Connect to the database**:
|
||||
```bash
|
||||
./connect.sh
|
||||
```
|
||||
|
||||
3. **Stop the container**:
|
||||
```bash
|
||||
docker-compose down
|
||||
```
|
||||
|
||||
## SSL Connection Details
|
||||
|
||||
The setup provides enterprise-grade security with:
|
||||
- **Encryption**: TLSv1.3 with TLS_AES_256_GCM_SHA384 cipher
|
||||
- **Key Size**: 256-bit encryption
|
||||
- **Certificate**: Self-signed with full verification
|
||||
- **Authentication**: SCRAM-SHA-256 password hashing
|
||||
|
||||
## Manual Connection
|
||||
|
||||
You can also connect manually using psql:
|
||||
```bash
|
||||
psql "host=localhost port=5432 dbname=ploughgres user=ploughgres_user sslmode=verify-full sslrootcert=secrets/ca_crt"
|
||||
```
|
||||
|
||||
For non-interactive connection, set the PGPASSWORD environment variable:
|
||||
```bash
|
||||
export PGPASSWORD=$(cat secrets/postgres_password || echo "change_me_in_production")
|
||||
psql "host=localhost port=5432 dbname=ploughgres user=ploughgres_user sslmode=verify-full sslrootcert=secrets/ca_crt"
|
||||
```

# PloughGres Usage Guide
|
||||
|
||||
## Quick Start
|
||||
|
||||
1. **Start the PostgreSQL container:**
|
||||
```bash
|
||||
./start.sh
|
||||
```
|
||||
|
||||
2. **Connect to the database:**
|
||||
```bash
|
||||
./connect.sh
|
||||
```
|
||||
|
||||
3. **Stop the container:**
|
||||
```bash
|
||||
docker-compose down
|
||||
```
|
||||
|
||||
## Common Operations
|
||||
|
||||
### Database Management
|
||||
- **View container status:** `docker ps`
|
||||
- **View container logs:** `docker logs ploughgres-db`
|
||||
- **Access PostgreSQL shell:** `./connect.sh`
|
||||
- **Restart container:** `docker-compose restart`
|
||||
|
||||
### SSL Connection Testing
|
||||
The setup uses TLSv1.3 with 256-bit encryption. Connection details:
|
||||
- **Host:** localhost
|
||||
- **Port:** 5432
|
||||
- **Database:** ploughgres
|
||||
- **User:** ploughgres_user
|
||||
- **SSL Mode:** verify-full (certificate verification enabled)
|
||||
|
||||
### Data Persistence
|
||||
- Database data is stored in `./data/` directory
|
||||
- SSL certificates are in `./secrets/` directory
|
||||
- All data remains in the project directory (userspace)
|
||||
|
||||
### Security Features
|
||||
- ✅ SSL/TLS encryption (TLSv1.3)
|
||||
- ✅ Certificate verification
|
||||
- ✅ SCRAM-SHA-256 authentication
|
||||
- ✅ Row-level security enabled
|
||||
- ✅ Audit logging
|
||||
- ✅ Encryption functions (pgcrypto)
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Container Issues
|
||||
- **Container won't start:** Check `docker logs ploughgres-db`
|
||||
- **Port conflicts:** Ensure port 5432 is available
|
||||
- **Permission issues:** Check file permissions in `secrets/` directory
|
||||
|
||||
### SSL Connection Issues
|
||||
- **Certificate errors:** Verify certificates exist in `secrets/`
|
||||
- **Connection refused:** Ensure container is running and healthy
|
||||
- **Authentication failed:** Check password in `secrets/postgres_password.txt`
|
||||
|
||||
## Development
|
||||
|
||||
### Making Changes
|
||||
1. Stop the container: `docker-compose down`
|
||||
2. Make your changes
|
||||
3. Rebuild and restart: `./start.sh`
|
||||
|
||||
### Viewing SSL Status
|
||||
Connect to the database and run:
|
||||
```sql
|
||||
SELECT ssl, version, cipher, bits FROM pg_stat_ssl WHERE pid = pg_backend_pid();
|
||||
```
|
||||
|
||||

|
||||
- `docker-compose.yml` - Container configuration
|
||||
- `start.sh` - Initialization and startup script
|
||||
- `connect.sh` - SSL connection test script
|
||||
- `Dockerfile` - Container image definition
|
||||
- `secrets/` - SSL certificates and passwords
|
||||
