vRA7 to vRO Extensibility Magic Secrets Revealed Part 3

Let’s tie it all together now and test this integration. In Part 1 you learned about vRA 7 to vRO architecture and how we pass data. In Part 2 we created a workflow in vRO that will recieve custom properties from vRA into attributes in vRO to tell vRO workflows how and what you want to automate. In this guide we will finish off the integration in vRA by creating the needed custom properties in our blueprint as well as configuring an event broker subscription.

  2. Hi Ryan,

    great and very usefull demo and explanations, just wondering how you get the helloworld.log working with the
    mynewscript = myscript + ” ” + ipaddress in vRO
    because if the script you passed in myscript custom property in vRA is equal to
    echo “Hello World, my ip address is $1” > /helloworld.log, then the mynewscript is equal to
    echo “Hello World, my ip address is $1” > /helloworld.log 192.168.110.200
    in your example, so it doesnt work…well
    or I missed something like the $1 usage ???

    • Hi,

      I am using $1 as a variable in the script, so when it executes the ip address 192.168.200 is the argument for that variable. So the result in the log should read Hello World, my ip address is 192.168.200 This is just an example of how to pass values around in vRO.

  3. I used the above workflow but replace last action item of the Workflow with Copy file from vco to VM Workflow, its been failing with error unable to read property sdk connection; can you let me know how can I overcome this issue.
