Deploy microservices

This section explains how to deploy interconnected applications (microservices) on Crane Cloud, such as frontend and backend applications that need to communicate with each other.

Deployment process

Initial setup

• Click the Create App button
• Select Deploy Microservices option

First application configuration (e.g. Backend)

Fill in required application details:

• Application name
• Image details
• Number of replicas (if needed)
• Add any necessary environment variables specific to this service

Second application configuration (e.g. Frontend)

Fill in the second application's details

Configure environment variables:

• Create variables that reference the first application
• Select the source application (e.g. backend) for URL or other needed values
• Specify variable names that will be used to access these values

Environment variables management

Each application has its own Environment Vars section in the settings

You can view and manage:

• Application-specific variables
• Inter-service connection variables
• Shared environment variables

Best practices

• Use clear, descriptive names for your applications
• Document all environment variables
• Test inter-service communication variables before full deployment
• Maintain proper security practices when sharing service information

Important notes

• Ensure all required environment variables are properly set
• Verify service connections before deploying
• Check application logs if services fail to communicate
• Consider security implications when sharing service information
