Capistrano3::Postgres

Installation

Add this line to your application's Gemfile:

gem 'capistrano3-postgres', require: false

or:

gem 'capistrano3-postgres', require: false, group: :development

And then execute:

$ bundle

Or install it yourself as:

$ gem install capistrano3-postgres

Usage

Capistrano3::Postgres supports Dotenv and Figaro gems and automatically loads environment variables from .env/application.yml files if they are used in the project.

    # Capfile

    require 'capistrano3/postgres'

then you can use cap -vT to list tasks

cap postgres:backup:create # Creates dump of a database(By default stores it to ../shared/postgres_backup directory)
cap postgres:backup:download # Downloads dump to local server(By default stores file in ./tmp/postgres_backup directory)
cap postgres:backup:import # Imports last dump file to local database of your choice.
cap postgres:replicate # Performs create, download and import step by step.

You will be prompted for password and local database name that you want to use for restore. In most cases you will need to provide environment

cap production postgres:replicate

Sometimes it's a good idea to create dump before each deploy.

before 'deploy:starting', 'postgres:backup:create'

All downloaded dump files will be deleted after importing. If you want to keep them, you can set:

set :postgres_keep_local_dumps, 5 # Will keep 5 last dump files.

To save on disk space, you can set the compression level. Gzip 0-9 are supported, default is 0:

set :postgres_backup_compression_level, 6 # Will use gzip level 6 to compress the output.

If you are using different clusters:

set :postgres_remote_cluster, '9.6/main'

If you don't need one or more tables dumped:

set :postgres_backup_exclude_table, ['personal_data', 'logs'] # Will not dump tables
set :postgres_backup_exclude_table_data, -> { ['personal_data', 'logs'] } # Will not dump data for this tables

If you need only specific tables to be dumped:

set :postgres_backup_table, -> { ['users', 'orders'] }

If you need to support rails 6+ multiple database support, please set database_name to use:

set :postgres_database, 'primary'
