Multiple zone ids from cloudflare_zones in terraform - terraform

Question

So i have a terraform variable type list(string) that is called zones and contains
zones = [
"example.com",
"example2.com",
"example3.com",
...
]
and i m using data cloudflare_zones resource to fetch all zones info
data "cloudflare_zones" "zones" {
for_each = toset(var.zones)
filter {
name = each.value
}
}
Output for each of the zones
data.cloudflare_zones.zones["example.com"]
{
"filter" = tolist([
{
"account_id" = ""
"lookup_type" = "exact"
"match" = ""
"name" = "example.com"
"paused" = false
"status" = ""
},
])
"id" = "9f7xxx3xxxx"
"zones" = tolist([
{
"id" = "e13xxxx"
"name" = "example.com"
},
])
}
To fetch the zone id you need to parse data.cloudflare_zones as below:
data.cloudflare_zones.zones["example.com"].zones[0].id
What i want to create then is a variable that will be an object with all the zones names as keys and zone ids ad values, so i can use them in other resources.
For Example:
zones_ids =
{
"example.com" = "xxxzone_idxxx",
"example2.com" = "xxxzone_id2xxx",
"example3.com" = "xxxzone_id3xxx",
...
}
I would like to achieve this inside locals block
locals {
...
}

Answer 1

That should be easy:
locals {
zones_ids = { for k,v in data.cloudflare_zones.zones: k => v.zones[0].id }
}
Or alternatively:
locals {
zones_ids = { for k,v in data.cloudflare_zones.zones: v.zones[0].name => v.zones[0].id }
}

Answer 2

The above answers helped me here but did not give me the final answer. For anyone looking to update A records for cloudflare with a list of domain names that gets the zone_ids for you. Here is how I did it:
locals {
domains = ["example1.com", "example2.com"]
}
data "cloudflare_zones" "zones" {
count = "${length(local.domains)}"
filter {
name = "${element(local.domains, count.index)}"
}
}
locals {
zones_ids = { for k,v in data.cloudflare_zones.zones: k => v.zones[0].id }
}
resource "cloudflare_record" "redir-A-record" {
for_each = local.zones_ids
zone_id = each.value
name = "#"
value = "24.1.1.1"
type = "A"
proxied = false
}
resource "cloudflare_record" "redir-A-record-www" {
for_each = local.zones_ids
zone_id = each.value
name = "www"
value = "24.1.1.1"
type = "A"
proxied = false
}
Getting output for these values did not seem to work based on the above answer. This could of just been my confusion but I wanted to print out the zone_id for each domain. I found since it is a tuple it requires the use of a number instead of a name so I was required to do the following to get the proper output:
# Get information for Domain 1
output "Domain_Information" {
value = data.cloudflare_zones.zones[0].zones[0].id
}
# Get information for Domain 2
output "Domain_Information2" {
value = data.cloudflare_zones.zones[1].zones[0].id
}
There is a way to loop this in output with Terraform but in my case I only had 2 domains and did not need to spend additional time on this.
Now when I want to spin up a server in AWS and have multiple domains point to 1 IP address this code works.
This line here posted by #Marko E was the solution to my issues for looping and saving the data that could be used later.:
locals {
zones_ids = { for k,v in data.cloudflare_zones.zones: k => v.zones[0].id }
}
