Configuration
Variables
The following variables are required:
| Variable | Description | Examples |
|---|---|---|
| aws_region | AWS region to create the AMI | eu-west-2 |
| aws_subnet_filter_name | A valid filter (wildcards allowed) to select subnet for the builder when creating the AMI | example-subnet-name-* |
| version | SEMVER version number used in the AMI name | 1.0.0 |
Service Configuration
The AMI will be built with a generic prometheus.yml configuration which configures Prometheus to monitor itself (similar to this example) and can be used for any basic testing as required. Specific EC2 instances and environments created from this AMI should replace this file with their own targets and requirements.
