Docker Network Integration Script (ncomp)

Overview

This script is designed to streamline the process of integrating a custom network into Docker Compose services. It automates the task of adding a specified network to all services in a Docker Compose file and ensures the network is properly defined and recognized by Docker Compose.

Features

• Automatic Network Creation: Creates a Docker network if it does not already exist.
• Dynamic Network Integration: Adds a specified network to all services in a Docker Compose file.
• Custom Network Support: Supports custom network names as specified by the user environment.
• Error Handling: Provides error output if the Docker Compose process encounters issues.

Requirements

• Python 3.x
• Docker Python SDK
• PyYAML

Environment Variables

• SHARED_NETWORK: The name of the network to be integrated into Docker Compose services. Default is "shared_network".
• COMPOSE_FILE: The path to the Docker Compose file. Default is "docker-compose.yml".

Usage

1. Set Environment Variables (optional): Define SHARED_NETWORK and COMPOSE_FILE if you want to use custom values.
2. Run the Script: Execute the script in the same directory as your Docker Compose file or specify the path using the COMPOSE_FILE environment variable.

Example

# Run with custom network name and Docker Compose file
SHARED_NETWORK=my_network COMPOSE_FILE=my_docker_compose.yml ncomp up
