Terraform module that creates an Vultr instance running Mailcow on Fedora CoreOS.

Module usage is basically the same as vultr_server, with a few differences:

• a conf variables accepts your Mailcow config
• SSH key is accepted using ssh_key instead of the usual ssh_key_ids as CoreOS does not work with the usual method of adding SSH keys to Vultr servers
• os_id isn't configurable because we use Fedora CoreOS

provider "vultr" {
}

module "mailcow" {
  source    = "./../.."
  conf      = file("mailcow.conf")
  ssh_key   = var.ssh_key 
  
  region_id = "4"    # Seattle
  plan_id   = "401"  # 1CPU + 2GB RAM + 64GB NVMe drive
}

resource "vultr_reverse_ipv4" "ptr_record" {
  instance_id = module.mailcow.server.id    # NB: vultr_server attributes available as '.server'
  ip          = module.mailcow.server.main_ip
  reverse     = "mail.example.com"
}

The mailcow server can be accessed using SSH. You'll need the SSH key you provided in the ssh_key variable and the IP address assigned to the server (module.mailcow.server.main_ip).

$ ssh core@{server-ip-address}

You're configuration is available at /opt/mailcow-dockerized. It may take a minute to become available. If in doubt, run systemctl status clone-mailcow.service to check the status of config set up.

Mailcow is running as the systemd mailcow. You can check its status with systemctl status mailcow.service and get logs with journalctl -u mailcow.
