However, for your own projects, we strongly advise pinning each module to the exact version\n\u003e you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic\n\u003e approach for updating versions to avoid unexpected changes.\n\n\n\n\n\n\n\n\n\u003c!-- markdownlint-disable --\u003e\n## Makefile Targets\n```text\nAvailable targets:\n\n  help                                Help screen\n  help/all                            Display help for all targets\n  help/short                          This help short screen\n  lint                                Lint terraform code\n\n```\n\u003c!-- markdownlint-restore --\u003e\n\u003c!-- markdownlint-disable --\u003e\n## Requirements\n\n| Name | Version |\n|------|---------|\n| \u003ca name=\"requirement_terraform\"\u003e\u003c/a\u003e [terraform](#requirement\\_terraform) | \u003e= 1.0 |\n| \u003ca name=\"requirement_aws\"\u003e\u003c/a\u003e [aws](#requirement\\_aws) | \u003e= 2.0 |\n\n## Providers\n\n| Name | Version |\n|------|---------|\n| \u003ca name=\"provider_aws\"\u003e\u003c/a\u003e [aws](#provider\\_aws) | \u003e= 2.0 |\n\n## Modules\n\n| Name | Source | Version |\n|------|--------|---------|\n| \u003ca name=\"module_label\"\u003e\u003c/a\u003e [label](#module\\_label) | cloudposse/label/null | 0.25.0 |\n| \u003ca name=\"module_security_group\"\u003e\u003c/a\u003e [security\\_group](#module\\_security\\_group) | cloudposse/security-group/aws | 2.2.0 |\n| \u003ca name=\"module_ssh_key_pair\"\u003e\u003c/a\u003e [ssh\\_key\\_pair](#module\\_ssh\\_key\\_pair) | cloudposse/key-pair/aws | 0.19.0 |\n| \u003ca name=\"module_this\"\u003e\u003c/a\u003e [this](#module\\_this) | cloudposse/label/null | 0.25.0 |\n\n## Resources\n\n| Name | Type |\n|------|------|\n| [aws_cloudwatch_metric_alarm.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/cloudwatch_metric_alarm) | resource |\n| [aws_ebs_volume.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ebs_volume) | resource |\n| [aws_eip.additional](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/eip) | resource |\n| [aws_eip.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/eip) | resource |\n| [aws_iam_instance_profile.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/iam_instance_profile) | resource |\n| [aws_iam_role.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/iam_role) | resource |\n| [aws_instance.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/instance) | resource |\n| [aws_network_interface.additional](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/network_interface) | resource |\n| [aws_network_interface_attachment.additional](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/network_interface_attachment) | resource |\n| [aws_volume_attachment.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/volume_attachment) | resource |\n| [aws_ami.info](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/ami) | data source |\n| [aws_caller_identity.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/caller_identity) | data source |\n| [aws_iam_policy_document.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/iam_policy_document) | data source |\n| [aws_region.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/region) | data source |\n\n## Inputs\n\n| Name | Description | Type | Default | Required |\n|------|-------------|------|---------|:--------:|\n| \u003ca name=\"input_additional_ips_count\"\u003e\u003c/a\u003e [additional\\_ips\\_count](#input\\_additional\\_ips\\_count) | Count of additional EIPs | `number` | `0` | no |\n| \u003ca name=\"input_additional_tag_map\"\u003e\u003c/a\u003e [additional\\_tag\\_map](#input\\_additional\\_tag\\_map) | Additional key-value pairs to add to each map in `tags_as_list_of_maps`.
