Serverless.yml Reference
Here is a list of all available properties in serverless.yml when the provider is set to aws.
Root properties
# serverless.yml
# Org name
# This is your Serverless Framework Organization, often named after your company or team.
# This is tied to your user account or license key.
# This is optional. A default org is auto-set within your .serverlessrc file in your root directory, but recommended to ensure you are always deploying to the correct org.
org: my-org
# App name
# The "App" concept acts as a parent container for one or more "Services," which you can configure via the `app` property in `serverless.yml`.
# Setting an `app` activates Serverless Framework Dashboard features for that Service, such as tracking deployments, sharing outputs and secrets, and enabling metrics, traces, and logs.
# This is optional. If you don't want to use Dashboard features, don't set this.
app: my-app
# Service name
# This is the name of your project/app/service/microservice (it's scope is up to you).
service: my-service
# serverless.yml
# Org name
# This is your Serverless Framework Organization, often named after your company or team.
# This is tied to your user account or license key.
# This is optional. A default org is auto-set within your .serverlessrc file in your root directory, but recommended to ensure you are always deploying to the correct org.
org: my-org
# App name

# Setting an `app` activates Serverless Framework Dashboard features for that Service, such as tracking deployments, sharing outputs and secrets, and enabling metrics, traces, and logs.
# This is optional. If you don't want to use Dashboard features, don't set this.
app: my-app
# Service name
# This is the name of your project/app/service/microservice (it's scope is up to you).
service: my-service

# "default" Parameters are available across all Stages.
# Otherwise, Stage-specific Parameters can be set here.
params:
default:
domain: ${sls:stage}.myapi.com
prod:
domain: myapi.com
dev:
domain: dev.myapi.com
# Example usage
# This will change depending on the Stage set.

# serverless.yml
# Stage parameters
# Parameters are Stage-specific values you can reference elsewhere in your YAML via ${param:my-value}
# Parameters can be defined in `serverless.yml` (and Dashboard and CLI options)

# Otherwise, Stage-specific Parameters can be set here.
params:
