# Built-in Strategy

Blue/Green in action

*Spinnaker being originally a Netflix tool, Blue/Green deployment are called Red/Black deployment in order to reflect the company's colors.* 

## Exercice:

Spinnaker implements Red/Black deployment using Kubernetes ReplicaSet.

#### Deploy new application version using Red/Black

We are going to update our application from version "red" to version "black".

* Go back to the pipeline "**build-in-strategy**"
* Select the deploy `manifest stage`
* Scroll to Deploy `manifest stage configuration section`
* check the box, to let spinnaker manages traffic
* Select the namespace where did you deployed the service
* Select the service created in the beginning of the exercise
* Select strategy: Red/Black

* Save the pipeline
* run the Pipeline "**build-in-strategy**" with the parameter **version=red**
* wait for completion
* run the Pipeline "**build-in-strategy**" with the parameter **version=black**
* head to the Infrastructure page during deployment in order to observe how Spinnaker handle Red/Black deployment

Great! now that we have implemented the Red/Black deployment, we need to implement the rollback pipeline
