self.artifact_repository = S3Bucket.new('foobucket')
self.deployment_mechanism = CodeDeploy.new(asg: 'AutoScalingGroup')

end

Constructor Details

#initialize(asg: [], role: 'CodeDeployRole', app_name: nil, group_name: nil, config_name: 'CodeDeployDefault.OneAtATime') ⇒ CodeDeploy

Returns a new instance of CodeDeploy.

Parameters:

  • asg (Array, String) (defaults to: []) —

    The logical name of the AutoScalingGroup to create and manage a Deployment Group for in CodeDeploy.

  • role (String) (defaults to: 'CodeDeployRole') —

    IAM role with AWSCodeDeployRole policy. CodeDeployRole is considered as default role if its not specified.

  • app_name (String, nil) (defaults to: nil) —

    (nil) The name of the CodeDeploy Application. By default, this is the same as the stack name, and probably what you want. If you have multiple deployments in a single Stack, they must have unique names.

  • group_name (String, nil) (defaults to: nil) —

    (nil) The name of the CodeDeploy Deployment Group. By default, this is the same as app_name.

  • config_name (String) (defaults to: 'CodeDeployDefault.OneAtATime') —

    Name of the Deployment Config to use for CodeDeploy, By default we use CodeDeployDefault.OneAtATime.
