Failed to create stack using about cloudformation HOT 2 CLOSED

We have found that this can occur when dnshostnames are disabled for the VPC. Normally this parameter is not required but in this scenario the manager installer is sometimes unable to resolve a hostname for itself. If this is not the case for your environment I'd definitely be interested to know more about how this occurred, but in the short term the fix is likely the same.

v0.5 in progress has a fix for this by adding the AddressAndPortsScreen.ManagerAddress=<local_ipv4 from metadata> line to dsmConfiguration.properties in the installDSM config. Fix is in and tested on the marketplace side; I haven't yet moved it to the RHEL template but should have that completed by next week. The fix on marketplace should be direct portable to current RHEL and looks like this:

                "installDSM"     : {
                    "commands" : {
                        "0-sethostnameinprops" : {
                            "command" : {
                                "Fn::Join" : [
                                    "",
                                    [
                                        "echo ",
                                        "\"AddressAndPortsScreen.ManagerAddress=$(curl http://169.254.169.254/latest/meta-data/local-ipv4/)\" >> /etc/cfn/dsmConfiguration.properties"
                                    ]
                                ]
                            },
                            "ignoreErrors" : "false"
                        },
