Variant

Provides a model for application variants, including documenting behaviour like RACK_ENV and APP_ENV.

bundle add variant

Variants are used to indicate the default configuration for an application. There are four suggested variants:

The general mechanism for specifying a variant is on the command line before running the application:

VARIANT=production falcon serve

In your code, you access this like so:

Variant.default # => :production
Variant.for(:database) # => :production

You can specify system-specific variants. These are useful when you have e.g. 2 different database clusters, or you want to run a development instance connected to a production database.

VARIANT=production DATABASE_VARIANT=production-aws

In your code, you access this like so:

Variant.default # => :production
Variant.for(:database) # => :'production-aws'

If you don't specify a system-specific variant, it will be the same as the default variant.

This gem provides bake recipes for setting the variants as outlined above.

bake variant:production ...
bake variant:staging ...
bake variant:development ...
bake variant:testing ...

In addition, the tasks also support specifying overrides:

% bake variant:development database=production variant:show
0.01s     info: Environment [pid=417910] [2020-02-29 11:43:25 +1300]
              | {"VARIANT"=>"development", "DATABASE_VARIANT"=>"production"}
