Simple example of using terraform.io to provision on FIWARE Lab Cloud a VM instance with a public IP and firewalling rules

terraform-fiware-lab.tf

### Variables ###

# Variables can be set by exporting environment variable TF_VAR_varname

variable keypair {
  description = "SSH keypair to be used for VM authentication. The keypair should already be registered in FIWARE Lab Cloud."
}

variable image_id {
  default = "7f2b4b3e-1cda-4e16-a09a-a97c600f78c0" 
}

variable network_name {
  default = "node-int-net-01"
}

variable floatingip_pool {
  default = "public-ext-net-01"
}



# Configure the OpenStack Provider. Empty because it uses environment variables OS_AUTH_URL, OS_USERNAME, OS_PASSWORD, OS_TENANT_NAME, OS_REGION_NAME 
provider "openstack" {
}

### resources ###
