Kubernetes is an orchestration platform that’s perfect for blue-green deployments. We can, for instance, use the platform to dynamically create the green environment, deploy the application, switch over the user’s traffic, and finally delete the blue environment.

Consequently, how do you do blue-green deployment with helm?
Blue-green deployment is a technique that reduces downtime and risk by running two identical production environments called Blue and Green. At any time, only one of the environments is live, with the live environment serving all production traffic. For this example, Blue is currently live and Green is idle.
How does Bluegreen deployment work?
A blue/green deployment is a deployment strategy in which you create two separate, but identical environments. One environment (blue) is running the current application version and one environment (green) is running the new application version.
How many types of deployments in Kubernetes?
Kubernetes uses two deployment strategies called “Recreate” and “RollingUpdate” to recreate pods. We can define those strategies in . spec. strategy.
What are deployment strategies?
A deployment strategy is a way to change or upgrade an application. The aim is to make the change without downtime in a way that the user barely notices the improvements. The most common strategy is to use a blue-green deployment.
What are the deployment strategies in Kubernetes?

- Rolling Deployment. A rolling deployment is the default deployment strategy in Kubernetes. …
- Recreate. …
- Ramped Slow Rollout. …
- Best-Effort Controlled Rollout. …
- Canary Deployment.
What is blue green release strategy?
Blue green deployment is an application release model that gradually transfers user traffic from a previous version of an app or microservice to a nearly identical new release—both of which are running in production.
What is recreate deployment strategy?
Recreate. The recreate strategy is a dummy deployment which consists of shutting down version A then deploying version B after version A is turned off. This technique implies downtime of the service that depends on both shutdown and boot duration of the application.
What is the difference between POD and deployment in Kubernetes?
As we now know, a pod is the smallest unit of Kubernetes used to house one or more containers and run applications in a cluster, while deployment is a tool that manages the performance of a pod.
What’s the difference between a blue-green deployment and a rolling deployment?
The difference between the rolling and blue/green strategies is that in a rolling strategy, the infrastructure is not in a separate network or environment like in blue/green. Like in-place deployments, rolling deployments suffer from a risky rollback if issues occur during deployment.
Which steps do you follow for a blue green deployment using Kubernetes service and deployment definitions?
There are four steps to this tutorial – Installing Minikube, Installing and verifying Istio, deploying two versions of the same app, and finally configuring the services for blue/green deployments.
Why is it called blue green deployment?
This strategy greatly improved error detection because test and production applications were now running in similar environments. After achieving great success with this strategy, they coined the term Blue-Green deployment strategy to give it a name.
Why is it called blue green?
They finally settled on using colors instead, which didn’t have a natural order. Thus, they planned names like blue, green, or orange (they avoided red because it implied danger). In the end, it turned out they only needed two environments. And so the term blue-green was coined.
