grunt-debian-package

Create debian package from grunt build

Grunt plugin to create a Debian package, allowing JavaScript applications to be easily integration into a Debian or Ubuntu based continuous delivery pipeline.

Getting Started

This plugin requires Grunt ~0.4

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-debian-package --save-dev

You will also need to install two debian tools used to create and lint the debian package, as follows:

sudo apt-get install devscripts
sudo apt-get install debhelper

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-debian-package');

To print out verbose messages during packaging use --verbose, for example:

grunt debian_package --verbose

To debug any issues with the debian_package task configuration:

1. use the node-inspector:

sudo npm install -g node-inspector
node --debug-brk $(which grunt) debian_package --verbose

2. in another shell process:

node-inspector

3. open the url displayed in a browser

The "debian_package" task

Overview

In your project's Gruntfile, add a section named debian_package to the data object passed into grunt.initConfig().

Typically the options section would not need to be provided as these values are read from the package.json file for the project. In this example, however, custom options are used to override the default values. For more details on the default values see below.

grunt.initConfig({
  debian_package: {
    options: {
        maintainer: {
            name: "James D Bloom",
            email: "jamesdbloom@email.com"
        },
        prefix: "prefix-",
        name: "package_name",
        postfix: "-postfix",
        short_description: "the short description",
        long_description: "the long description added to the debian package",
        version: "2.0.0",
        build_number: "1",
        target_architecture: "amd64",
        category: "devel",
        links: [
            {
                source: '/var/log/${name}',
                target: '/var/log/tomcat7'
            },
            {
                source: '/etc/init.d/${name}',
                target: '/etc/init.d/tomcat7'
            }
        ],
        directories: [
            '/var/app/${name}'
        ],
        dependencies: "couchdb, redis-server"
    },
    files: [
        {
            expand: true,       // enable dynamic expansion 
            cwd: 'build/',      // src matches are relative to this path 
            src: [              // actual pattern(s) to match 
                '**/*.js',
                '**/*.html',
                '**/*.css'
            ],
            dest: '/var/www/'   // destination path prefix 
        },
        {                       // use template in file path 
            src:  'config/<%= grunt.package.name %>.json',
            dest: '/var/www/<%= grunt.package.name %>.json'
        }
    ]
  }
});

This will result in a package being created called prefix-package_name-postfix-2.0.0-1.deb. The configuration above will result in the package containing all *.js, *.css and *.html files in the build directory. These files will be installed into /var/wwww/ when the package is installed. In addition the package will contain /var/wwww/package_name.json as a copy of the config/package_name.json file in the project. The config above will also add two soft-links and an empty directory into the package. Both the links and directories sections can use the following placeholders ${name}, ${version} and ${build_name} to refer to the package name, version and build number respectively.

Using the dpkg -c package_name-2.0.0-1.deb command it is possible to see the package contents:

Options

options.maintainer.name

Type: String Default value: process.env.DEBFULLNAME or package.json author.name

This value specifies the maintainer's name for the debian package. The default value is taken from the standard debian environment variable DEBFULLNAME.

options.maintainer.email

Type: String Default value: process.env.DEBEMAIL or package.json author.email

This value specifies the maintainer's email for the debian package. The default value is taken from the standard debian environment variable DEBEMAIL.

options.prefix

Type: String Default value: ''

This value specifies a prefix for the debian package name. This is useful is the package name is taken from the package.json but requires a prefix (i.e. for company name).

options.name

Type: String Default value: package.json name

This value specifies the name of the debian package. The default value is taken from the package.json name value.

options.postfix

Type: String Default value: ''

This value specifies a postfix for the debian package name. This is useful is the package name is taken from the package.json but requires a postfix (i.e. for git branch).

options.short_description

Type: String Default value: package.json description first line only

This value specifies the short description for the debian package, for example, this is displayed when listing all packages using the dpkg -l command. The default value is taken from the first line of the package.json description value.

options.long_description

Type: String Default value: package.json description all except first line

This value specifies the multiple line long description for the debian package, for example, this is displayed when quering package status using the dpkg -s <package.name> command. The default value is taken from all text after the end of the first line of the package.json description value.

options.version

Type: String Default value: package.json version

The first part of the version number. This version number is intended to respresent the logical version of the code in the package. The default value is taken from the package.json version value.

options.build_number

Type: String Default value: process.env.BUILD_NUMBER || process.env.DRONE_BUILD_NUMBER || process.env.TRAVIS_BUILD_NUMBER

The second part of the version number. This version number is intended to respresent a specific build of the package, for example this package might represetn the Jenkins or drone.io or TravisCI build number. The default value is taken from an environment variable called BUILD_NUMBER or DRONE_BUILD_NUMBER or TRAVIS_BUILD_NUMBER which is compatible with Jenkins, drone.io and TravisCI respectively.

options.target_architecture

Type: String (possible values are amd64, i386, all, any) Default value: all

The targeted architecture

options.category

Type: String Default value: misc

The software category. Used to fill the "section" field of the control file

options.preinst.src

Type: String Default value: undefined

This value specifies the path of the preinst script, the contents of this file will be copied into the preinst script. If both src and contents are specified src will take precedence. The preinst script is executed before the package is unpacked from its Debian archive (".deb") file. Many 'preinst' scripts stop services for packages which are being upgraded until their installation or upgrade is completed (following the successful execution of the 'postinst' script).

options.preinst.contents

Type: String Default value: undefined

This value specifies the contents of the preinst script, the value will be copied into the preinst script. If both src and contents are specified src will take precedence. The preinst script is executed before the package is unpacked from its Debian archive (".deb") file. Many 'preinst' scripts stop services for packages which are being upgraded until their installation or upgrade is completed (following the successful execution of the 'postinst' script).

options.postinst.src

Type: String Default value: undefined

This value specifies the path of the postinst script, the contents of this file will be copied into the postinst script. If both src and contents are specified src will take precedence. The postinst script typically completes any required configuration of the package foo once foo has been unpacked from its Debian archive (".deb") file. Often, 'postinst' scripts ask the user for input, and/or warn the user that if he accepts default values, he should remember to go back and re-configure that package as the situation warrants. Many 'postinst' scripts then execute any commands necessary to start or restart a service once a new package has been installed or upgraded.

options.postinst.contents

Type: String Default value: undefined

This value specifies the contents of the postinst script, the value will be copied into the postinst script. If both src and contents are specified src will take precedence. The postinst script typically completes any required configuration of the package foo once foo has been unpacked from its Debian archive (".deb") file. Often, 'postinst' scripts ask the user for input, and/or warn the user that if he accepts default values, he should remember to go back and re-configure that package as the situation warrants. Many 'postinst' scripts then execute any commands necessary to start or restart a service once a new package has been installed or upgraded.

options.prerm.src

Type: String Default value: undefined

This value specifies the path of the prerm script, the contents of this file will be copied into the prerm script. If both src and contents are specified src will take precedence. The prerm script typically stops any daemons which are associated with a package. It is executed before the removal of files associated with the package.

options.prerm.contents

Type: String Default value: undefined

This value specifies the contents of the prerm script, the value will be copied into the prerm script. If both src and contents are specified src will take precedence. The prerm script typically stops any daemons which are associated with a package. It is executed before the removal of files associated with the package.

options.postrm.src

Type: String Default value: undefined

This value specifies the path of the postrm script, the contents of this file will be copied into the postrm script. If both src and contents are specified src will take precedence. The postrm script typically modifies links or other files associated with foo, and/or removes files created by the package.

options.postrm.contents

Type: String Default value: undefined

This value specifies the contents of the postrm script, the value will be copied into the postrm script. If both src and contents are specified src will take precedence. The postrm script typically modifies links or other files associated with foo, and/or removes files created by the package.

options.links

Type: String Default value: undefined

This value specifies a list of soft-links that should be added into the package. Each soft-link is specified using a source and a target value. Both the links and directories sections can use the following placeholders ${name}, ${version} and ${build_name} to refer to the package name, version and build number respectively, see example above.

options.directories

Type: String Default value: undefined

This value specifies a list of directories that should be added into the package. Both the links and directories sections can use the following placeholders ${name}, ${version} and ${build_name} to refer to the package name, version and build number respectively, see example above.

options.follow_soft_links

Type: Boolean Default value: undefined

This value specifies whether soft-links should be followed when copying files into the package. By default as this value is undefined soft-links will not be followed.

options.custom_template

Type: String Default value: undefined

This value specifies a custom template directory. It can be used to override the files of the default template (especially useful for overridding copyright or changelog). The content of the directory should have the following structure

- MakeFile
- debian
  - changelog
  - compat
  - control
  - copyright
  - dirs
  - links
  - rules
  - source
    - format

Any missing file will be replaced by the default ones (See packaging directory) The files from the custom_template directory are processed the same way than the default ones, so use of variables is possible

Files

The files configuration specifies the files to add into the package.

This task supports all the file mapping format Grunt supports. Please read Globbing patterns and Building the files object dynamically for additional details.

Usage Examples

Default Options

The following example configuration shows the default values for the options. A files section is added which will add all files in the dist directory into the /var/www/ directory in the package.

grunt.initConfig({
  debian_package: {
    files: {
        src: [
            'dist/**',
            '!dist'
        ]
        dest: '/var/www/'
    }
  },
});

Not providing any options will result in the following default values:

var properties = require(process.cwd() + '/package.json');
 
options: {
  maintainer: process.env.DEBFULLNAME && process.env.DEBEMAIL && {
      name: process.env.DEBFULLNAME,
      email: process.env.DEBEMAIL
  },
  name: properties.name,
  short_description: properties.description && properties.description.split(/\r\n|\r|\n/g)[0],
  long_description: properties.description && properties.description.split(/\r\n|\r|\n/g).splice(1).join(' '),
  version: properties.version,
  build_number: process.env.BUILD_NUMBER || process.env.DRONE_BUILD_NUMBER || process.env.TRAVIS_BUILD_NUMBER
  target_architecture: "all",
  category: "misc"
}

maintainer is taken from the standard debian environment variables DEBFULLNAME and DEBEMAIL. name, short_description, long_description and version are all read from the package.json. short_description is taken as the first line of the description value and long_description is taken as the rest of the description value. build_number is taken from the the environment variables BUILD_NUMBER or DRONE_BUILD_NUMBER or TRAVIS_BUILD_NUMBER which are the build number environment variables for Jenkins, drone.io and TravisCI respectively.

Future Plans

1. Add options to support custom copyright file
2. Add options to support generation of changelist from git log

Contributing

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
