Deploys the datadog forwarder and automatic log group subscription and retention policy lambdas across multiple AWS regions. Useful for capturing lambda@edge log groups generated just in time in multiple edge locations.
When a new cloudwatch log group is created the log-subscription lambda subscribes it to the datadog forwarder and the log-retention lambda sets the retention time to 14 days.
Copy example.tfvars and set the name of your datadog API key in secrets manager (last part of the ARN) and your default region. Make sure your datadog secret is replicated to all regions you are deploying to.
Auth with AWS and import the session into the environment.
