Solution for AWS Network Firewall Deployment Automations for AWS Transit Gateway.

• Node.js>12

Build the CDK code

cd source/
npm run build

Build the Network Firewall Solution CodeBuild source code

cd source/networkfirewallAutomation
tsc 

Build the templates for custom deployments

cd deployments/
chmod +x ./build-s3-dist.sh
./build-s3-dist.sh [SOLUTION_DIST_BUCKET] network-firewall-automation [VERSION_ID]

Run the unit tests

cd source/
chmod +x ./run-all-tests.sh

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

• Create an 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]-us-east-1.
• Create the distribution files using the script provided in the build section above.
• Create the S3 Key in the bucket network-firewall-automation/[VERSION_ID]/
• Create the S3 Key in the bucket network-firewall-automation/latest/
• Copy the file ./deployment/regional-s3-assets/network-firewall-automation.zip to the location s3://[BUCKET_NAME]-[REGION]/network-firewall-automation/[VERSION_ID]/
• Copy the file ./deployment/regional-s3-assets/network-firewall-configuration.zip to the location s3://[BUCKET_NAME]-[REGION]/network-firewall-automation/latest/

Once the above steps are completed, use the file ./deployment/global-s3-assets/aws-network-firewall-deployment-automations-for-aws-transit-gateway.template to create a stack in CloudFormation.

aws-network-firewall-deployment-automations-for-aws-transit-gateway consists of:

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