Usernames for the Linux User that is used to log into the EC2 Instances.S3 object where Public key will be stored.S3 Bucket where Public key will be stored.In this file, change a few of the parameters (look for FIXME) based on your setup before providing the script to AWS Cloud Formation.Ĭloudformation.yaml needs to be configured with

Despite many advantages that Amazon Lambda offers, a monitoring system is required to manage its complex environments, scalable workloads and resources, and to help reduce the MTTR and possibly prevent avoidable issues. *Ĭloudformation.yaml is a Cloud Formation script to create the Lambda Function in AWS. AWS Lambda is an event-based serverless computing platform, with built-in auto scaling and infrastructure management capabilities. Zip the contents of the repository $ cd rotate-ssh-aws-master/ $ zip -r rotate-ssh-lambda.zip.

The public key is put to an object in AWS S3.ĭownload the Lambda code from this repository $ wget -O rotate_ssh.zip $ unzip rotate_ssh.zip In this step, we use CloudFormation to create a Lambda Function that rotates the SSH key and adds the public key in the ~.ssh/authorized_keys file in the instances. Steps C reate a Key Rotation Lambda using CloudFormation AWS Systems Manager: Rotation Lambda Function uses Systems Manager to run the script to add ssh public key in ~.ssh/authorized_keys.It also adds the public key in an object in AWS S3. Key Rotation Lambda: Lambda function rotates the SSH key and adds the public key in the ~.ssh/authorized_keys file in the instances having a specific tag.

You can trigger Lambda from over 200 AWS services and software as a service (SaaS) applications, and only pay for what you use.

tmp & aws cloudformation package -template-file cloudformation.yml -s3-bucket -output-template-file.

Make sure that the bucket is in the same region where you’ll deploy the template. Keys are rotated by the Key Rotation Lambda function periodically. AWS Lambda is a serverless, event-driven compute service that lets you run code for virtually any type of application or backend service without provisioning or managing servers. Use the script below, just fill in the bucket name where the AWS CLI will upload the lambda code. AWS Security Manager: An AWS service used to store the SSH keys (both Private and Public).Monitoring Lambda: This Lambda function is responsible for securely logging in using SSH to various instances, find the state of the services, and raise alarms if something is broken.EC2 Instances: These are the instances on which your services are running.The primary idea behind this architecture is to securely access EC2 instances over SSH and monitor the services.
