CDK Construct for managing EC2 key pairs

CDK EC2 Key Pair

AWS CDK L3 construct for managing EC2 Key Pairs.

CloudFormation doesn't directly support creation of EC2 Key Pairs. This construct provides an easy interface for creating Key Pairs through a custom CloudFormation resource. The private key is stored in AWS Secrets Manager.

Usage

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.core as cdk
import aws_cdk.aws_ec2 as ec2
from cdk_ec2_key_pair import KeyPair

# Create the Key Pair
key = KeyPair(self, "A-Key-Pair",
    name="a-key-pair",
    description="This is a Key Pair"
)

# Grant read access to the private key to a role or user
key.grant_read(some_role)

# Use Key Pair on an EC2 instance
ec2.Instance(self, "An-Instance", {
    "key_name": key.name
})

The private key will be stored in AWS Secrets Manager. The secret name is prefixed with ec2-private-key/, so in this example it will be saved as ec2-private-key/a-key-pair.

To download the private key via AWS cli you can run:

aws secretsmanager get-secret-value \
  --secret-id ec2-private-key/a-key-pair \
  --query SecretString \
  --output text

Roadmap

• Secret prefix should be configurable
• Name should be optional
• Tagging support in a more standard way
