5 | 6 | This **reusable Terraform module** streamlines the **creation** and **management** of an **EC2 key pair** on **AWS**. It **generates** the key pair, securely **stores** the **private key** in **AWS Systems Manager Parameter Store (SSM)**, and returns the **key pair name** and **SSM parameter ARN** for easy reference in other **infrastructure resources**. By using this module, you can efficiently manage key pairs while maintaining **security** and **compliance** in your AWS environment. 7 | 8 | ## Usage Example 9 | 10 | ```hcl 11 | module "key_pair" { 12 | source = "saturnops/keypair/aws" 13 | key_name = "example-key" 14 | environment = "production" 15 | ssm_parameter_path = "production-example-key" 16 | } 17 | ``` 18 | Refer [this](https://github.com/saturnops/terraform-aws-ssh-keypair/tree/main/examples) for more examples. 19 | 20 | 21 | ## Retrieve Private Key 22 | 23 | To Retrieve the Private key from SSM: 24 | ```bash 25 | aws ssm get-parameter --name "" --region "" --query Parameter.Value --output text 26 | ``` 27 | 28 | Additionally, to save the private key to a file: 29 | ```bash 30 | aws ssm get-parameter --name "" --region "" --with-decryption --query Parameter.Value --output text > keypair.pem 31 | ``` 32 | 33 | ## IAM Permission 34 | The required IAM permissions to create resources from this module can be found [here](https://github.com/saturnops/terraform-aws-ssh-keypair/blob/main/IAM.md) 35 | 36 | 37 | 38 | ## Requirements 39 | 40 | | Name | Version | 41 | |------|---------| 42 | | [terraform](#requirement\_terraform) | >= 1.0 | 43 | | [aws](#requirement\_aws) | >= 4.21 | 44 | | [tls](#requirement\_tls) | >= 3.4 | 45 | 46 | ## Providers 47 | 48 | | Name | Version | 49 | |------|---------| 50 | | [aws](#provider\_aws) | >= 4.21 | 51 | 52 | ## Modules 53 | 54 | | Name | Source | Version | 55 | |------|--------|---------| 56 | | [key\_pair](#module\_key\_pair) | terraform-aws-modules/key-pair/aws | 2.0.0 | 57 | 58 | ## Resources 59 | 60 | | Name | Type | 61 | |------|------| 62 | | [aws_ssm_parameter.ssm_ec2_keypair](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ssm_parameter) | resource | 63 | 64 | ## Inputs 65 | 66 | | Name | Description | Type | Default | Required | 67 | |------|-------------|------|---------|:--------:| 68 | | [environment](#input\_environment) | Specifies the identifier for the environment where the key pair will be used. | `string` | `""` | no | 69 | | [key\_name](#input\_key\_name) | Specifies the name to be assigned to the key pair that will be generated. | `string` | `""` | no | 70 | | [ssm\_parameter\_path](#input\_ssm\_parameter\_path) | Specifies the SSM parameter name that will be used to store the generated key pair. | `string` | `"/example/ssm"` | no | 71 | 72 | ## Outputs 73 | 74 | | Name | Description | 75 | |------|-------------| 76 | | [key\_pair\_name](#output\_key\_pair\_name) | The name of the key pair generated for the EC2 instance. | 77 | | [ssm\_parameter\_arn](#output\_ssm\_parameter\_arn) | The Amazon Resource Name (ARN) of the SSM parameter used to store the EC2 instance key pair. | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | ## 86 | 87 | 88 | 89 | 90 | 91 | - Please give our GitHub repository a ⭐️ to show your support and increase its visibility.. 92 | 93 | 94 | 95 | 96 | 97 | -------------------------------------------------------------------------------- /examples/complete/README.md: -------------------------------------------------------------------------------- 1 | # AWS EC2 key pair 2 | 3 | Configuration in this directory creates EC2 key pair. 4 | 5 | ## Usage 6 | 7 | To run this example you need to execute: 8 | 9 | ```bash 10 | $ terraform init 11 | $ terraform plan 12 | $ terraform apply 13 | ``` 14 | 15 | Note that this example may create resources which cost money.
