Database connection issues can significantly impact the functionality of your R2R deployment. This guide will help you diagnose and resolve common database connection problems for both Postgres.
Before diving into database-specific issues, try these general troubleshooting steps:
Check Database Service Status: Ensure the database service is running.
Verify Network Connectivity: Ensure the R2R service can reach the database.
Check Logs: Examine R2R and database container logs for error messages.
Verify Environment Variables: Ensure all necessary environment variables are correctly set in your Docker Compose file or deployment configuration.
Check Postgres Connection String:
POSTGRES_*
environment variables in your R2R configuration.Test Postgres Connection:
Check Postgres Logs:
Verify Postgres User and Database:
Check Postgres Network Settings:
pg_hba.conf
file allows connections from the R2R container’s IP range.Ensure your Docker Compose file includes proper health checks for database services:
If network issues persist:
Inspect the Docker network:
Use network debugging tools within containers:
Check if volume permissions are causing issues:
Inspect volume permissions:
Adjust permissions if necessary:
To avoid future database connection issues:
If you’re still experiencing issues:
By following this guide, you should be able to diagnose and resolve most database connection issues in your R2R deployment. Remember to always keep your database and R2R versions compatible and up to date.
