Pulumi (pulumi.io) offers an open source platform to create/manage and deploy your infrastructure in realy programming languages like JavaScript/TypeScript, Go and Python. As Cloud platforms the major 3 cloud providers are supported and additionally you can also use Pulumi with OpenStack and Kubernetes to deploy your applications in the cloud. In this talk we will take a look how Pulumi is different to traditional solutions like Terraform or the Cloud Provider specific solutions (e.g. CloudFormation). The main focus will be on deploying your services on top of Kubernetes. The talk will contain a little theory part about Pulumi, the rest of the talk is more focused on demos and practical parts. One focus of the talk is the difference of Pulumi to kubectl and helm (or to be precise how they complement each other. As a takeaway of this talk you should understand the basics of Pulumi and know what are the differences to the traditional deployment tools.

6. Creating Kubernetes resources
K8s
API
“kubectl create –f ...“
„ACK“

7. Getting Feedback from K8s
K8s
API
“kubectl rollout status ...“
„Waiting for deployment "todo-app" rollout to finish:
3 of 5 updated replicas are available... “

8. “Debugging”
K8s
API
“kubectl get po –field-selector=status.phase!=Running“
„List of Pods that are not running“

12. Pulumi basics
● Pulumi manages projects
● A Stack is an instance of your project
● Pulumi can manage multiple stacks
● A Stack uses packages (e.g. AWS, GCP, ...)
● Each stack can be configured

13. Demo time!
