Environment Variables

Dokploy allows you to create and manage shared environment variables for your projects.

Overview

Shared environment variables allow you to:

  • Define values once and use them across multiple services
  • Maintain configuration consistency between services
  • Centrally manage sensitive information
Shared variables panel

Practical Example

Let's consider a common scenario where you have:

  • A PostgreSQL database
  • Two services that need to connect to this database

1. Define Shared Variable

In the project's shared variables section, define:

DATABASE_URL=postgresql://postgres:postgres@database:5432/postgres

2. Use the Variable in Services

In each service's environment variables tab, reference the shared variable:

DATABASE_URL=${{project.DATABASE_URL}}

Dokploy will automatically replace ${{project.DATABASE_URL}} with the value defined in the project's shared variables.

Best Practices

  • Use shared variables for credentials and configurations that repeat across services
  • Keep descriptive variable names
  • Document the purpose of each variable for easier maintenance

You can use shared enviroment variables in all the services available in dokploy.
