Batfish Network Analysis container running in ECS Cluster with Fargate behind a Load Balancer.

The cdk.json file tells the CDK Toolkit how to execute your app.

An example bash script is provided to dynamically grab the instance-id of the EC2 used to tunnel through to the ELB. The ELB is also grabbed dynamically with the AWS CLI toolkit.

• PortForwarding with SSM

-> Grab Instance ID by TAG 'Name' value of BatfishSSM

INSTANCE_ID=$(aws ec2 describe-instances \
               --filter "Name=tag:Name,Values=BatfishSSM" \
               --query "Reservations[].Instances[?State.Name == 'running'].InstanceId[]" \
               --output text)

-> Start StartPortForwardingSessionToRemoteHost through our EC2 Instance to remote ALB on port 9996
