Generates a config/database.yml file with the environment information from your database service.

Rails database yml

Generates a config/database.yml file with the environment information from your database service.

For this step you need to have a mysql or postgres. See the services on wercker devcenter for more information about services.

What's new

• Add support for the ewok stack.

Options

• service This option is not required. If set, it will load the template from the specified service; otherwise, it will infer the service from the environment.
• postgresql-min-message (optinal, default: warning): Set the min_messages parameter in the postgresql template.

Supported services

Currently wercker/postgresql and wercker/mysql for the old stack are supported. No further configuration is required for these services.

The following docker containers are supported in the new stack: postgres and mysql. Both have some required and recommended environment variables.

The postgresql container requires the POSTGRES_PASSWORD environment variable to be set. The other environment variables are POSTGRES_USER and POSTGRES_DB. All environment variables are used in this step, or use the same defaults as the container.

The mysql container requires the MYSQL_ROOT_PASSWORD, but this password won't be used by this step. Make sure you also set MYSQL_DATABASE, MYSQL_USER and MYSQL_PASSWORD. These are the environment variables that will be used by this step.

Example

The following wercker.yml:

box: wercker/ruby
services:
  - wercker/postgresql
build:
  steps:
    - rails-database-yml

Will generate the following config/database.yml:

test:
    adapter: postgresql
    encoding: "utf8"
    database: <%= ENV['WERCKER_POSTGRESQL_DATABASE'] %><%= ENV['TEST_ENV_NUMBER'] %>
    username: <%= ENV['WERCKER_POSTGRESQL_USERNAME'] %>
    password: <%= ENV['WERCKER_POSTGRESQL_PASSWORD'] %>
    host: <%= ENV['WERCKER_POSTGRESQL_HOST'] %>
    port: <%= ENV['WERCKER_POSTGRESQL_PORT'] %>
    min_messages: warning
