The amplify/example YAML configuration defines an Amplify app in AWS. The app is set up to use the Next.js framework with SSR (server-side rendering) and is linked to the GitHub repository "https://github.com/cloudposse/amplify-test2".

The app is set up to have two environments: main and develop. Each environment has different configuration settings, such as the branch name, framework, and stage. The main environment is set up for production, while the develop environments is set up for development.

The app is also configured to have custom subdomains for each environment, with prefixes such as example-prod and example-dev. The subdomains are configured to use DNS records, which are enabled through the subdomains_dns_records_enabled variable.

The app also has an IAM service role configured with specific IAM actions, and environment variables set up for each environment. Additionally, the app is configured to use the Atmos Spacelift workspace, as indicated by the workspace_enabled: true setting.

The amplify/example Atmos component extends the amplify/defaults component.

The amplify/example configuration is imported into the stacks/mixins/stage/dev.yaml stack config file to be provisioned in the dev account.

# stacks/mixins/stage/dev.yaml
import:
  - catalog/amplify/example

You can execute the following command to provision the Amplify app using Atmos:

atmos terraform apply amplify/example -s <stack>

Inputs

Name	Description	Type	Default	Required
additional_tag_map	Additional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id. This is for some rare cases where resources want additional configuration of tags and therefore take a list of maps with tag key, value, and additional configuration.	map(string)	{}	no
attributes	ID element. Additional attributes (e.g. workers or cluster) to add to id, in the order they appear in the list. New attributes are appended to the end of the list. The elements of the list are joined by the delimiter and treated as a single ID element.	list(string)	[]	no
