Hi all,

Anyone kindly send me one copy of HOT heat template that utilize the wait conditions (to control the boot sequence).

THANKS A lot!

Eric

I tried snippet as below: Not working for me. From the log seem the signal/curl did not yield any error. Though "first_wait" can not finish the instantiation and "second" never get instantiated.

 first:
    type: OS::Nova::Server
    properties:
      key_name: PCM-I
      flavor: m1.small
      user_data:
        str_replace:
          template: |
            #!/bin/bash -v
            **# TIME-CONSUMING TASKS here**
            /usr/bin/cfn-signal -s true $wait_handle
          params:
            $wait_handle: {get_resource: first_wait_handle}
  first_wait_handle:
    type: AWS::CloudFormation::WaitConditionHandle
  first_wait:
    type: AWS::CloudFormation::WaitCondition
    depends_on: first
    properties:
      Handle: {get_resource: first_wait_handle}
      Timeout: 1000
  second:
    type: OS::Nova::Server
    depends_on: first_wait
    properties:
      key_name: PCM-I
      image: v37
      flavor: m1.small
      networks:
        - port: { get_resource: server2_port }
      user_data: |
        #!/bin/bash
        echo "second is up"

the user data execution yield no error but the VM "second" can not the instantiate.

If I manually run the command in the vm... Same result. (please note that http://152.148.165.80:8000/v1 is Cloudformation address)
