AWS Resources - Websockets

Nitric Websockets are deployed to AWS using Amazon API Gateway.

AWS Resources

The following resources are created when deploying Websockets to AWS:

• API Gateway v2 Websocket APIs
• API Gateway v2 Stages
• API Gateway Integration
• Lambda Functions
• ECR Images
• IAM Policies

Deployment

During deployment the Nitric CLI builds your Websockets API's routes, methods and handlers:

• Files referenced by the services key in the nitric.yaml file are built into container images
• Built container images are pushed to the Amazon Elastic Container Registry as private images
• Functions in AWS Lambda are created to run the container images
• IAM policies are created enabling Websocket API Gateway to execute the Lambdas
• $default, $connect, and $disconnect routes are added to the Websocket API Gateway
