I’m using Octopus Variable sets to drive replacing JSON parameter values in ARM templates, but the whole process falls over if the ARM template requires an integer variable type rather than a string.
I package both my azure template and the azure parameters json files together in a zip and pass them to Octopus to process using the “Deploy an Azure Resource Manager Template” in-build step.
For example, in my Octopus variable set I have…
ovs-appServicePlan_myapp_skuTier with a value of “Free” which has a Variable type of Text
ovs-appServicePlan_myapp_workerSizeId with a value of 0 which is also set as Text (as there doesn’t appear to be a numeric/integer type available?)
In the JSON template set by Azure…
"appServicePlan_myapp_skuTier": {
"type": "string"
},
"appServicePlan_myapp_workerSizeId": {
"type": "int"
},
In the parameters file I have…
"appServicePlan_myapp_skuTier": {
"value": "#{ovs-appServicePlan_myapp_skuTier}"
},
"appServicePlan_myapp_workerSizeId": {
"value": "#{ovs-appServicePlan_myapp_workerSizeId}"
}
When the step runs everything is fine until the type integer in the parameters json file is hit…

This is a bit of a show-stopped for us. I believe it is because Octopus passes a string value back to the template that wants an integer.
Can this be worked around?? I couldn’t see anything in the variable sets that would allow anything other than a String/Text type associated with it.
