#### OpenStack
Ensure your OpenStack **Identity v2** credentials are loaded in environment
variables. This can be done by downloading a credentials .rc file from your
OpenStack dashboard and sourcing it:
No provider variables are hard coded inside `variables.tf` because Terraform
supports various authentication method for OpenStack, between identity v2 and
v3 API, `openrc` or `clouds.yaml`.
These are examples and may vary depending on your OpenStack cloud provider,
for an exhaustive list on how to authenticate on OpenStack with Terraform
please read the [OpenStack provider documentation](https://www.terraform.io/docs/providers/openstack/).
##### Recommended method : clouds.yaml
Newer recommended authentication method is to use a `clouds.yaml` file that can be store in :
* `Current Directory`
* `~/.config/openstack`
* `/etc/openstack`
`clouds.yaml` :
```
$ source ~/.stackrc
clouds:
mycloud:
auth:
auth_url: https://openstack:5000/v3
username: "username"
project_name: "projectname"
project_id: projectid
user_domain_name: "Default"
password: "password"
region_name: "RegionOne"
interface: "public"
identity_api_version: 3
```
Ensure that you have your Openstack credentials loaded into Terraform
environment variables. Likely via a command similar to:
If you have multiple clouds defined in your `clouds.yaml` file you can choose
the one you want to use with the environment variable `OS_CLOUD` :
```
$ echo Setting up Terraform creds && \
export TF_VAR_username=${OS_USERNAME} && \
export TF_VAR_password=${OS_PASSWORD} && \
export TF_VAR_tenant=${OS_TENANT_NAME} && \
export TF_VAR_auth_url=${OS_AUTH_URL}
export OS_CLOUD=mycloud
```
##### Deprecated method : openrc
When using classic environment variables, Terraform uses default `OS_*`
environment variables :
With identity v2 :
```
source openrc
env | grep OS
OS_AUTH_URL=https://openstack:5000/v2.0
OS_PROJECT_ID=projectid
OS_PROJECT_NAME=projectname
OS_USERNAME=username
OS_PASSWORD=password
OS_REGION_NAME=RegionOne
OS_INTERFACE=public
OS_IDENTITY_API_VERSION=2
```
With identity v3 :
```
source openrc
env | grep OS
OS_AUTH_URL=https://openstack:5000/v3
OS_PROJECT_ID=projectid
OS_PROJECT_NAME=username
OS_PROJECT_DOMAIN_ID=default
OS_USERNAME=username
OS_PASSWORD=password
OS_REGION_NAME=RegionOne
OS_INTERFACE=public
OS_IDENTITY_API_VERSION=3
OS_USER_DOMAIN_NAME=Default
```
Terraform does not support a mix of DomainName and DomainID, choose one or the
other :
```
* provider.openstack: You must provide exactly one of DomainID or DomainName to authenticate by Username
```
```
unset OS_USER_DOMAIN_NAME
export OS_USER_DOMAIN_ID=default
or
unset OS_PROJECT_DOMAIN_ID
set OS_PROJECT_DOMAIN_NAME=Default
```

### Terraform files
In the root folder, the following files might be created (either by Terraform
or manually), to prevent you from pushing them accidentally they are in a
`.gitignore` file in the `terraform/openstack` directory :
* `.terraform`
* `.tfvars`
* `.tfstate`
* `.tfstate.backup`
You can still add them manually if you want to.
## Initializing Terraform
Before Terraform can operate on your cluster you need to install required
plugins. This is accomplished with the command

You can enable debugging output from Terraform by setting
`OS_DEBUG` to 1 and`TF_LOG` to`DEBUG` before runing the terraform command
## Terraform output
Terraform can output useful values that need to be reused if you want to use Kubernetes OpenStack cloud provider with Neutron/Octavia LBaaS or Cinder persistent Volume provisioning:
- `private_subnet_id`: the subnet where your instances are running, maps to `openstack_lbaas_subnet_id`
- `floating_network_id`: the network_id where the floating IP are provisioned, maps to `openstack_lbaas_floating_network_id`
# Running the Ansible Script
