Creating a TypeScript Interface for Docker Compose YAML

Oct 13, 2025 by wbrum.org 86 views

Introduction

Docker Compose is a popular tool for defining and running multi-container Docker applications. It uses a YAML file to specify the services, networks, and volumes that make up the application. However, working with YAML files can be cumbersome, especially when dealing with complex applications. In this article, we will explore the possibility of using TypeScript bindings to Docker-Compose schema, making it easier to work with Docker Compose in a TypeScript project.

What are TypeScript Bindings?

TypeScript bindings are a way to create a TypeScript interface for a existing library or API. This allows developers to use the library or API in a TypeScript project, while still maintaining the benefits of TypeScript, such as type checking and code completion.

Existing Solutions

There are several existing solutions that provide TypeScript bindings for Docker Compose. One of the most popular ones is the docker-compose package, which provides a TypeScript interface for the Docker Compose API.

However, this package does not provide a direct way to work with the Docker Compose YAML schema. Instead, it provides a way to interact with the Docker Compose API, which can be used to create and manage Docker containers.

Creating a TypeScript Interface for Docker Compose YAML

To create a TypeScript interface for the Docker Compose YAML schema, we can use the yaml package, which provides a TypeScript interface for working with YAML files.

Here is an example of how we can create a TypeScript interface for the Docker Compose YAML schema:

import * as yaml from 'yaml';

interface Compose {
  name: string;
  services: {
    [service: string]: Service;
  };
}

interface Service {
  image: string;
  ports: string[];
  environment: { [key: string]: string };
}

const compose: Compose = {
  name: 'my-stack',
  services: {
    service1: {
      image: 'node:14',
      ports: ['3000:3000'],
      environment: {
        NODE_ENV: 'development',
      },
    },
    service2: {
      image: 'postgres:13',
      ports: ['5432:5432'],
      environment: {
        POSTGRES_USER: 'user',
        POSTGRES_PASSWORD: 'password',
      },
    },
  },
};

const yamlString = yaml.stringify(compose);
console.log(yamlString);

This code defines a TypeScript interface for the Docker Compose YAML schema, and then uses the yaml package to serialize the interface to a YAML string.

Running a Compose from a Service Description in a JS Object

Another interesting feature that could be added to the TypeScript bindings for Docker Compose is the ability to run a compose from a service description in a JS object.

This would allow developers to define a service in a JS object, and then use the TypeScript bindings to create a Docker Compose YAML file from that service description.

Here is an example of how we can implement this feature:

import { up } from 'docker-compose';

const compose = {
  name: 'my-stack',
  services: {
    service1: { /* .. */ },
    service2: { /* .. */ }
  }
}

upAll({ 
  cwd: path.join(__dirname),
  compose,
})

This code defines a service description in a JS object, and then uses the up function from the docker-compose package to create a Docker Compose YAML file from that service description.

Conclusion

In this article, we explored the possibility of using TypeScript bindings to Docker-Compose schema, making it easier to work with Docker Compose in a TypeScript project.

We created a TypeScript interface for the Docker Compose YAML schema, and then used the yaml package to serialize the interface to a YAML string.

We also implemented a feature that allows developers to run a compose from a service description in a JS object.

This feature would allow developers to define a service in a JS object, and then use the TypeScript bindings to create a Docker Compose YAML file from that service description.

Future Work

There are several areas where this work can be improved. One area is to add more features to the TypeScript bindings for Docker Compose, such as support for networks and volumes.

Another area is to improve the performance of the TypeScript bindings for Docker Compose, by using more efficient algorithms and data structures.

Finally, another area is to make the TypeScript bindings for Docker Compose more user-friendly, by providing better documentation and examples.
