1 Swagger first approach
2 Start from API Publisher

Swagger First Approach
Start from the Swagger definition
Deploy the API Gateway in Kubernetes
Import the API to the API Publisher
Productize the API and publish the API
Productize the API by adding necessary
information and publish the API for public
access
Access the API from the DevPortal
By giving the Swagger definition to Kubernetes
Using apictl (command line tool) import
the API to the API PublisherCreate/ Generate a Swagger definition for
the microservices
Using an access token, invoke the API
from the devportal

19. 19
Start from API Publisher
Create an API in the API Publisher
Productize the API and publish the API in Kubernetes
Deploy the API Gateway in Kubernetes
Access the API from the DevPortal
Using an access token, invoke the API from
the devportal
By selecting a Kubernetes environment, publish
the API in Kubernetes
As of the API Manager and Kubernetes
integration, an API Gateway gets
deployed in Kubernetes
Using the API publisher, create an API
