azure – Splitting a comma separated string

You can use the split() function to split a string into a list.

output output_tf_testap_outbound_ip_addresses {
  value = [${split(,, azurerm_app_service.testap.outbound_ip_addresses)}]
}

After that you can then index it by using the element(list, index) syntax:

output first_ip {
  value = ${element(split(,, azurerm_app_service.testap.outbound_ip_addresses), 0}
}

You should also normally be able to use the list[index] syntax like this:

output first_ip {
  value = ${split(,, azurerm_app_service.testap.outbound_ip_addresses)[0]}
}

However there seems to be a bug in Terraform 0.11 that prevents slicing the result of the split function, throwing the following error:

Error: Error loading /tmp/tf-split-test/main.tf: Error reading config
for output foo: parse error at 1:25: expected } but found [

You could use a local to split the list and then slice that to get around this if youd prefer to use this syntax over the element function.

locals {
  outbound_ip_addresses_list = ${split(,, azurerm_app_service.testap.outbound_ip_addresses)}
}

output first_ip {
  value = ${local.outbound_ip_addresses_list[0]}
}
