docker-modem

What is docker-modem?

The docker-modem npm package is a low-level Docker API client for Node.js. It allows developers to interact with Docker's REST API programmatically, enabling them to manage Docker containers, images, networks, and more directly from their Node.js applications.

What are docker-modem's main functionalities?

Managing Containers

This feature allows you to create and manage Docker containers. The code sample demonstrates how to create a new container using the 'alpine' image and run a simple command inside it.

const Docker = require('docker-modem');
const docker = new Docker({ socketPath: '/var/run/docker.sock' });

const createContainer = async () => {
  const opts = {
    path: '/containers/create',
    method: 'POST',
    options: {
      Image: 'alpine',
      Cmd: ['echo', 'Hello World']
    }
  };
  docker.dial(opts, (err, data) => {
    if (err) throw err;
    console.log(data);
  });
};

createContainer();

Managing Images

This feature allows you to manage Docker images. The code sample demonstrates how to pull the 'alpine' image from Docker Hub.

const Docker = require('docker-modem');
const docker = new Docker({ socketPath: '/var/run/docker.sock' });

const pullImage = async () => {
  const opts = {
    path: '/images/create',
    method: 'POST',
    options: {
      fromImage: 'alpine',
      tag: 'latest'
    }
  };
  docker.dial(opts, (err, data) => {
    if (err) throw err;
    console.log(data);
  });
};

pullImage();

Managing Networks

This feature allows you to manage Docker networks. The code sample demonstrates how to create a new network with the 'bridge' driver.

const Docker = require('docker-modem');
const docker = new Docker({ socketPath: '/var/run/docker.sock' });

const createNetwork = async () => {
  const opts = {
    path: '/networks/create',
    method: 'POST',
    options: {
      Name: 'my_network',
      Driver: 'bridge'
    }
  };
  docker.dial(opts, (err, data) => {
    if (err) throw err;
    console.log(data);
  });
};

createNetwork();

Other packages similar to docker-modem

dockerode

Dockerode is a high-level Docker API client for Node.js. It provides a more user-friendly interface compared to docker-modem and includes additional abstractions to simplify common tasks. While docker-modem is more low-level and closer to the raw Docker API, dockerode offers a more convenient and higher-level API for managing Docker resources.

node-docker-api

Node-docker-api is another Docker API client for Node.js. It offers a balance between low-level control and high-level convenience. It provides a promise-based interface, making it easier to work with asynchronous operations compared to docker-modem's callback-based approach.

README

docker-modem

Docker's Remote API network layer module.

docker-modem will help you talking with Docker, since it already implements all the network strategies needed to support all Docker's Remote API endpoints.

It is the module powering (network wise) dockerode and other modules.

Tests

• Tests are implemented using mocha and chai. Run them with npm test.
• Check dockerode tests, which is indirectly co-testing docker-modem.
