# Dockerfile Utilities
 [](https://coveralls.io/github/rcjsuen/dockerfile-utils?branch=master) [](https://david-dm.org/rcjsuen/dockerfile-utils) [](https://opensource.org/licenses/MIT)
This is a collection of utilities for working with Dockerfiles powered by Node.js written in TypeScript.
To [install and run](#installation-instructions) these utilities, you will need to have [Node.js](https://nodejs.org/en/download/) or [Docker](https://www.docker.com/get-docker) installed on your computer.
Supported features:
- formatting
- linting
## Development Instructions
If you wish to build and compile this project, you must first install [Node.js](https://nodejs.org/en/download/) if you have not already done so.
After you have installed Node.js and cloned the repository with Git, you may now proceed to build and compile the project with the following commands:
```
npm install
npm run build
npm test
```
If you are planning to change the code, use `npm run watch` to get the TypeScript files transpiled on-the-fly as they are modified.
## Installation Instructions
To add this library as a dependency to your project, please add `dockerfile-utils` as a dependency in your project's package.json file.
## Running the CLI with Node.js
To install and use the `dockerfile-utils` command line interface, please install the [dockerfile-utils npm module](https://www.npmjs.com/package/dockerfile-utils).
The `-g` flag will install the NPM module globally onto your computer.
```
npm install -g dockerfile-utils
```
After the installation has completed, you can run the CLI using the `dockerfile-utils` binary.
```
> dockerfile-utils --help
Usage: dockerfile-utils []
Options:
-h, --help Output usage information
-v, --version Output version information
Commands:
format Format a Dockerfile
lint Validate a Dockerfile
```
## Running the CLI with Docker
You can use `docker run` to launch the command line interface with Docker.
This removes the requirement of needing to have Node.js installed locally on your computer.
The `dockerfile-utils` binary is available as a Docker image under the name `rcjsuen/dockerfile-utils`.
```
> docker run rcjsuen/dockerfile-utils --help
Usage: dockerfile-utils []
Options:
-h, --help Output usage information
-v, --version Output version information
Commands:
format Format a Dockerfile
lint Validate a Dockerfile
```
To format or lint a Dockerfile in the current working directory, please use the following commands.
```
> docker run -v `pwd`/Dockerfile:/Dockerfile rcjsuen/dockerfile-utils format /Dockerfile
```
```
> docker run -v `pwd`/Dockerfile:/Dockerfile rcjsuen/dockerfile-utils lint /Dockerfile
```
