Secrets Management

Overview

SilverLinux uses a centralized secrets file for shared credentials and sensitive configuration.

Location:

/srv/secrets/company.env

This file is stored on the server and is never committed to Git.

---

Purpose

The secrets file provides a single location for:

• SMTP credentials
• Database passwords
• Application secrets
• OAuth client secrets
• Future API keys

Applications should load secrets using:

env_file:
  - /srv/secrets/company.env

• Use environment variables whenever possible.
• Use .env.example files for documentation.
• Rotate credentials immediately if exposure is suspected.

---

Backup Requirements

The following file must be included in server backups:

/srv/secrets/company.env

Loss of this file may prevent applications from starting correctly.

---

Recovery Procedure

If the server must be rebuilt:

1. Restore /srv/secrets/company.env
2. Verify file permissions
3. Deploy Docker stacks
4. Verify services can access required variables
5. Verify SMTP functionality
6. Verify database connectivity

---

Security Notes

The secrets file contains credentials for multiple services.

Access should be restricted to system administrators only.

Recommended permissions:

chmod 600 /srv/secrets/company.env

Recommended ownership:

root:root
