Line 535 in c0b9957

Value: !Sub "https://${ec2Instance.PublicIp}:${listenPort}"

Suggest adding a condition to the output eg.

  DCVwebConsole:
    Condition: useElasticIP
    Description: DCV web console (login as ec2-user)
    Value: !Sub "https://${ec2Instance.PublicIp}:${listenPort}"

Thanks for the report.

Stack creation fails as your EC2 is not provisioned in a public subnet, i.e. it does not have a public IP.
For EC2 in public subnet, assignStaticIP provides option to associate a static internet IP via Elastic IP.

As per EC2 instance in private subnet, you can either remove or comment out the last 3 lines in yaml file.

Add displayPublicIP CloudFormation parameter. Set this to No if EC2 has no public IP.
Editing of template file is no longer required.

Stack creation fails with "Attribute: PublicIp was not found for resource" when assignStaticIP parameter is "No"
