Generators

Plugin generator

Use the plugin generator to create a ManageIQ plugin.

For example, to create a plugin called ManageIQ::MyPlugin, do the following

cd manageiq
bundle exec rails generate manageiq:plugin ManageIQ::MyPlugin

This will create the directory plugins/manageiq-my_plugin, and you will see the creation progress emitted to the console:

create
create  .codeclimate.yml
...

By default, the plugin will be created in the plugins directory, but you can specify an alternate directory with --path <path>.

Core modifications

In addition to creating to new plugin, the generator will also modify some core ManageIQ files in order connect the application with the new plugin.

The following lines are added to the Gemfile:

group :my_plugin, :manageiq_default do
  manageiq_plugin "manageiq-my_plugin" # TODO: Sort alphabetically...
end

During active development, you can replace the second line with

gem 'manageiq-my_plugin', :path => 'plugins/manageiq-my_plugin'

Now you can run bundle install to activate the new plugin.

Provider generator

If you are creating a provider plugin, you can use the provider generator to emit some extra scaffolding. The provider generator is the same as the plugin generator but with some extra features.

For example, to create a provider plugin called ManageIQ::Providers::AwesomeCloud, do the following:

cd manageiq
bundle exec rails generate manageiq:provider ManageIQ::Providers::AwesomeCloud --manager-type=cloud

Much like the plugin generator, you can pass --path to change the path. Additionally, you also have the following options

• [--vcr], [--no-vcr] # Enable VCR cassettes (Default: --no-vcr)

  Adds some scaffolding to support VCR recordings for specs.

• [--scaffolding], [--no-scaffolding] # Generate default class scaffolding (Default: true)

  Adds some scaffolding for a dummy cloud provider, including implementations of core models and common workers. The generated scaffolding is similar to the dummy provider repo.

• [--manager-type=MANAGER_TYPE] # What type of manager to create, required if building scaffolding

  Indicates what type of manager to create, for example: cloud, container, infra, physical, etc… --help will print the full list of possible manager types.

Core modifications

The following lines are added to your Gemfile:

### providers

group :awesome_cloud, :manageiq_default do
  manageiq_plugin "manageiq-providers-awesome_cloud" # TODO: Sort alphabetically...
end

Until your plugin is pushed upstream you can override the gem for local development by adding the following to a bundler.d/plugins.rb:

override_gem "manageiq-providers-awesome_cloud", :path => "../plugins/manageiq-providers-awesome_cloud"

Create an AwesomeCloud instance

Start rails console by executing bundle exec rails c and perform the following in the rails console, to create the cloud manager with an associated authentication.

ems = ManageIQ::Providers::AwesomeCloud::CloudManager.create!(:name => 'CloudAwesome', :zone => Zone.default_zone)
ems.update_authentication(:default => {:userid => user, :password => pass})
