How to assign floating ip address using terraform?

I’m unable to join floating ip and droplet creation.

# I create a resource:
resource "digitalocean_droplet" "mail" {
  image = "centos-7-x64"
  name = "mail"
  region = "${var.region}"
  size = "2gb"
  private_networking = true
}
#I create a floating ip:
resource "digitalocean_floating_ip" "mail" {
  droplet_id = "${digitalocean_droplet.mail.id}"
  region = "${var.region}"
}

The IDs are the same, but the IP’s are not.

$ doctl compute droplet list
ID      Name    Public IPv4 Public IPv6 Memory  VCPUs   Disk    Region  Image           Status  Tags
38296000    mail    188.166.174.104         2048    2   40  lon1    CentOS 7.3.1611 x64 active  
$ doctl compute fip list
IP      Region  Droplet ID  Droplet Name
67.207.68.145   lon1    38296000    mail

How do I get the droplet to take the floating IP address?

Thanks,

When you assign a floating IP address to a droplet you’re actually just adding an additional IPv4 interface. Meaning that your droplet is now accessible by two public IP addresses, the IP address assigned to the droplet originally and the new floating IP.

So in your case, you were actually successful in assigning the floating IP. Your droplet (ID# 38296000) is reachable at both 188.166.174.104, the IP assigned to the droplet when it was created, and 67.207.68.145, the floating IP.

These two tutorials provide helpful information regarding setting up and implementing floating IPs:

Hope this helps. Good Luck!
