Making use of Outputs in deployment scripts

[deniscooper]

Thanks to some help i've got my template working exactly as needed. The template builds a new azure vm, then runs a deployment script within the template to setup some on-premises resources, such as a local ad account and group. I need it to also update the IP address in DNS. The deployment script is running with PowerShell from the template. Im passing in parameters into the script from the rest of the template, but for the IP address, i need it to pass in the IP which is produced in the output networkDetails

output networkDetails string = networkInterface.properties.ipConfigurations[0].properties.privateIPAddress

i tried to create a variable from the output but it says you can't do that, so im not sure how i can pass the IP address from the output into my deployment script.

Do you mind sharing the entire template?

Sorry I replied as an answer.

One way of doing it is to change the value for the arguments property to:

arguments: '-groupName ${groupName} -serverFQDN ${serverFQDN} -serverIP ${networkInterface.properties.ipConfigurations[0].properties.privateIPAddress}'

Or you can declare a variable and pass that in to the arguments like this:

var ipAddress = networkInterface.properties.ipConfigurations[0].properties.privateIPAddress

arguments: '-groupName ${groupName} -serverFQDN ${serverFQDN} -serverIP ${ipAddress}'

Ahh that makes perfect sense. I think I must just have been having a mind block and wasn’t thinking straight. I’ll give it another go tomorrow or later. Thanks girl the advice.

Cool! If it works for you, please mark it as the answer to make sure that the discussion gets closed.

This worked perfectly thank you - not sure how to mark your post as an answer though.
