robhurring / db-sync

Allows dumping and restoring of databases from a config file (Pretty rough :)

DbSync

Handles pg_dump and pg_restore from a common config file of servers and databases

Installation

Or install it yourself as:

1. clone this repo
2. rake build
3. rake install

Usage

db-sync requires a YAML file if your server configurations and passwords. To get started run the db-sync init call to create a blank template in ~/.db-sync.yml. Edit this file and define your apps, as well as their environments and any other configuration you many need.

Dumping from a remote server

Given you filled out your config with something like:

# define your apps and environments for syncing and pulling the database
apps:
  ecommerce:
    production:
      # make sure you can SSH to this server `ssh [e-mail]` should work
      server:
        host: myapp.com
        user: deploy
      db:
        host: db.myapp.com
        database: ecommerce_production
        username: postgres
        password: somecrazypasswordinproduction
    local:
      db:
        database: ecommerce_development
        username: postgres

You can dump the production database to your Desktop by doing the following:

db-sync dump ecommerce:production > ~/Desktop/production.dump

This will build the necessary pg_dump commands and issue them over SSH and stream the data back to STDOUT.

Restore your local database from a dumpfile

Given the above configuration, and your dumpfile is at ~/Desktop/production.dump you can issue the following command to restore your local DB with the production data:

db-sync restore ecommerce:local < ~/Desktop/production.dump
