     1  # Basic OpenStack architecture with networking
     2  
     3  This provides a template for running a simple architecture on an OpenStack
     4  cloud.
     5  
     6  To simplify the example, this intentionally ignores deploying and
     7  getting your application onto the servers. However, you could do so either via
     8  [provisioners](https://www.terraform.io/docs/provisioners/) and a configuration
     9  management tool, or by pre-baking configured images with
    10  [Packer](http://www.packer.io).
    11  
    12  After you run `terraform apply` on this configuration, it will output the
    13  floating IP address assigned to the instance. After your instance started,
    14  this should respond with the default nginx web page.
    15  
    16  First set the required environment variables for the OpenStack provider by
    17  sourcing the [credentials file](http://docs.openstack.org/cli-reference/content/cli_openrc.html).
    18  
    19  ```
    20  source openrc
    21  ```
    22  
    23  Afterwards run with a command like this:
    24  
    25  ```
    26  terraform apply \
    27    -var 'external_gateway=c1901f39-f76e-498a-9547-c29ba45f64df' \
    28    -var 'pool=public'
    29  ```
    30  
    31  To get a list of usable floating IP pools run this command:
    32  
    33  ```
    34  $ nova floating-ip-pool-list
    35  +--------+
    36  | name   |
    37  +--------+
    38  | public |
    39  +--------+
    40  ```
    41  
    42  To get the UUID of the external gateway run this command:
    43  
    44  ```
    45  $ neutron net-show FLOATING_IP_POOL
