dockerx

Use Docker environments to configure and run command-line tools.

Example

Setup

First, setup the DockerX command-line tool. For this demo, we will assume that you've already cloned this repository, and plan to link it globally for development purposes.

> cd /path/to/repo
> npm link

Next, create the following configuration file. This lets DockerX know which commands you want to support, and how to properly configure the Docker environment for each command.

# ~/.dockerx/config.yml

commands:
  node:
    image: 'node:latest'
    command: '/usr/local/bin/node'

Finally, run the following command:

> dockerx node

If you do not already have the image installed on your machine, it will take a short while to download and extract the image. Once this step has completed, you will be connected to the Node.js REPL in a new container.

You can also use a Bash alias to simplify this command:

> alias node='dockerx node'
> node  # Runs the Node.js REPL

A few things to note:

• The directory where you ran the dockerx command ($PWD) is automatically mounted to /code/<folder-name>, so you can access these files as needed.
• The working directory has been set to the location above.
• When you exit the Docker environment, the container will automatically be cleaned up for you.
  • This uses the --rm flag from the Docker CLI. For more information, please refer to the Docker documentation.
