Grunt Database Migrations

push/pull databases from one location to another using Grunt. Inspired by https://github.com/getdave/grunt-deployments. At first planned as fork, but later I understand what I want something more than push/pull only mysql databases.

IMPORTANT NOTE: the authors of this Plugin assume no responsibility for any actions which result from the usage of this script. You use it entirely at your own risk. It is strongly recommended that you test the script in a non-critical environment prior to rolling out for production use. Always manually backup your local and remote databases before using the script for the first time. No support can be provided for critical situations.

Getting Started

This plugin requires Grunt ~0.4.1

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-migrations --save-dev

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

grunt.loadNpmTasks('grunt-migrations');

This plugin was designed to work with Grunt 0.4.x. If you're still using grunt v0.3.x it's strongly recommended that you upgrade, but in case you can't please use v0.3.2.

Run this task with the grunt migrations[:sub-task] command.

Usage Example

migrations: {
  options: {
    backups: 'db_backup',
    environments: {
      local: {
        title: 'localhost',
        db: {
          host: '0.0.0.0',
          name: '<local_db_name>',
          user: '<local_db_user>',
          pass: '<local_db_pass>',
          type: 'mysql'
        }
      },
      dev: {
        title: 'development',
        db: {
          host: 'localhost',
          name: '<dev_db_name>',
          user: '<dev_db_user>',
          pass: '<dev_db_pass>',
          type: 'mysql'
        },
        ssh: {
          host: '<dev_environment_host_or_IP>',
          user: '<dev_ssh_username>'
        }
      }
    }
  },
  'pull-dev': { action: 'pull', source: 'dev' },
  'pull-local': { action: 'pull', source: 'local' },
  'push-dev-to-local': { action: 'push', source: 'dev', target: 'local' },
  'push-local-to-dev': { action: 'push', source: 'local', target: 'dev' }
}

and run tasks from bash:

> grunt migrations:pull-dev
