ScalingoDatabasesRakeTasks

A gem providing rake tasks such as backup and restore for database manipulations on Scalingo.

Currently supported databases:

• MongoDB
• MySQL
• PostgreSQL

Available tasks for each database:

• backup_local: make a backup of local database
• backup_remote: make a backup of remote Scalingo database
• restore_local: restore a local database with an archive
• restore_remote: restore a remote Scalingo database with an archive

Usage

For remote operations you will have to set your shell's environment variable APP as your app name on Scalingo. The variable DB_ENV_NAME is optional, by default it will be the one generated when you provisionned the database addon. For example, if your database is a MongoDB then the variable will be SCALINGO_MONGO_URL.

Available Env Vars

Global:

• APP: Scalingo app name (mandatory)
• DB_ENV_NAME: Scalingo database connection var name, e.g. SCALINGO_MONGO_URL (optional)
• SSH_IDENTITY: specify a SSH identity file, e.g. ~/.ssh/id_rsa (optional)

MongoDB:

• FILE: your database config file name, e.g. database (optional)

PostgreSQL:

• PG_DUMP_CMD: specify the path or command name of the tool to use, default: pg_dump (optional)
• PG_RESTORE_CMD:specify the path or command name of the tool to use, default: pg_restore (optional)

Commands

To see the complete list of tasks: rake -T scalingo

Example of commands for MongoDB:

• rake scalingo:mongodb:backup_local
• rake scalingo:mongodb:backup_remote
• rake scalingo:mongodb:restore_local
• rake scalingo:mongodb:restore_remote

Backup and Restore

Backups are stored under the tmp folder of your project, the database type is part of the archive name (e.g. scalingo_mongodb_dump.tar.gz).

To restore from a specific archive, you'll have to give it the default archive name and put it inside of tmp folder before running the rake command.

SSH Identity

If you are not using a SSH agent and your default SSH identity file is not id_rsa you can specify your custom identity file path with the SSH_IDENTITY variable.

Installation

Add this line to your application's Gemfile:

gem 'scalingo_databases_rake_tasks'

And then execute:

$ bundle

Or install it yourself as:

$ gem install scalingo_databases_rake_tasks

For Rails apps nothing to do.

For other apps, add require "scalingo_databases_rake_tasks" to your Rakefile.
