#catchall ⇒ Object

    You might have to #{cancel_actions[:cfn]} the stack with:

        ufo #{cancel_actions[:ufo]}

    And try again after fixing the issue.

#deployment_configuration ⇒ Object

To reproduce

.ufo/config.rb

Ufo.configure do |config|
  config.ecs.maximum_percent = 150 # need at least 200 to go from 1 to 2 containers
  config.ecs.minimum_healthy_percent = 100
end

Event message error:

ERROR: (service app1-web-dev-EcsService-8FMliG8m6M2p) was unable to stop or start tasks during a deployment because of the service deployment configuration. Update the minimumHealthyPercent or maximumPercent value and try again.
