grunt-ssh-deploy (Version: 0.4.1)

SSH Deployment for Grunt using ssh2.

Getting Started

This plugin requires Grunt ~0.4.4

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-ssh-deploy --save-dev

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

grunt.loadNpmTasks('grunt-ssh-deploy');

The tasks

Overview

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

grunt.initConfig({
  environments: {
    environment: {
      // Environment specific options here
    }
  },
});

This plugin will connect to your remote host, add a directory to releases/ in your remote_path, and create a symlink to the latest release.

The symlink by default is current, you can change this by setting current_symlink.

Usage

By setting an environment, you can deploy each specific one with grunt ssh_deploy:environment or rolling back with grunt ssh_rollback:environment.

Options

options.host

Type: String

Remote host to connect to.

options.username

Type: String

The username to connect as on the remote server.
