Solution Overview

Solution for Cross-Account and Cross-Region scheduling EC2 and RDS instances/clusters using SSM Automation Runbooks.

Architecture Diagram

Prerequisites for Customization

• Node.js>12
• Python >3.7

AWS Solutions use two buckets: a bucket for global access to templates, which is accessed via HTTPS, and regional buckets for access to assets within the region, such as Lambda code. You will need:

• One global bucket that is access via the http end point. AWS CloudFormation templates are stored here. It must end with "-reference. Ex. "mybucket-reference"
• One regional bucket for each region where you plan to deploy using the name of the global bucket as the root, and suffixed with the region name. Ex. "mybucket-us-east-1"
• Your buckets should be encrypted and disallow public access

Note: When creating your buckets, ensure they are not publicly accessible. Use random bucket names. Disable public access. Use KMS encryption. And verify bucket ownership before uploading.

Build

Build the CDK code

cd source/
npm run build

Build the templates for custom deployments

• Configure the bucket name of your target Amazon S3 distribution bucket

export BUCKET-NAME-PREFIX=[RANDOM_BUCKET_NAME] 
export DIST_SOLUTION_BUCKET=$BUCKET-NAME-PREFIX-[REGION]
export SOLUTION_NAME=my-solution-name
export VERSION=my-version # version number for the customized code
export REGION=aws-region-code # e.g. us-east-1

• Now build the distributable:

chmod +x ./build-s3-dist.sh
./build-s3-dist.sh $BUCKET-NAME-PREFIX $SOLUTION_NAME $VERSION

cd ./deployment
chmod +x ./run-unit-tests.sh
./run-unit-tests.sh

Deploy

Follow the steps for deploying your custom version of the solution.

• Create a random S3 bucket with the bucket appended with the region in which the deployment is to be made. example, if the deployment is to be made in us-east-1 create a bucket name as [BUCKET-NAME-PREFIX]-us-east-1.
• Create the distribution files using the script provided in the build section above.
• Create the S3 Key in the bucket aws-instance-scheduler/[VERSION_ID]/
• Copy the file ./deployment/regional-s3-assets/instance-scheduler.zip to the location s3://[BUCKET-NAME-PREFIX]-[REGION]/aws-instance-scheduler/[VERSION_ID]/

Once the above steps are completed, use the file ./deployment/global-s3-assets/aws-instance-scheduler.template to create a stack in CloudFormation.

File structure

aws-instance-scheduler consists of:

• CDK constructs to generate necessary resources
• Microservices used in the solution
