--- | --- | ---
address - |  | IP address or domain name of the node
api_key string |  | Rackspace API key, overrides credentials. aliases: password
auth_endpoint - | Default: "https://identity.api.rackspacecloud.com/v2.0/" | The URI of the authentication service.
condition - | Choices: enabled disabled draining | Condition for the node, which determines its role within the load balancer
credentials path |  | File to find the Rackspace credentials in. Ignored if api_key and username are provided. aliases: creds_file
env string |  | Environment as configured in ~/.pyrax.cfg, see https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#pyrax-configuration.
identity_type - | Default: "rackspace" | Authentication mechanism to use, such as rackspace or keystone.
load_balancer_id - / required |  | Load balancer id
node_id - |  | Node id
port - |  | Port number of the load balanced service on the node
region string | Default: "DFW" | Region to create an instance in.
state - | Choices: present ← absent | Indicate desired state of the node
tenant_id - |  | The tenant ID used for authentication.
tenant_name - |  | The tenant name used for authentication.
type - | Choices: primary secondary | Type of node
username string |  | Rackspace username, overrides credentials.
validate_certs boolean | Choices: no yes | Whether or not to require SSL validation of API endpoints. aliases: verify_ssl
wait boolean | Choices: no ← yes | Wait for the load balancer to become active before returning
wait_timeout - | Default: 30 | How long to wait before giving up and returning an error
weight - |  | Weight of node

## Notes

Note

- The following environment variables can be used, `RAX_USERNAME`, `RAX_API_KEY`, `RAX_CREDS_FILE`, `RAX_CREDENTIALS`, `RAX_REGION`.
- `RAX_CREDENTIALS` and `RAX_CREDS_FILE` points to a credentials file appropriate for pyrax. See https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating
- `RAX_USERNAME` and `RAX_API_KEY` obviate the use of a credentials file
- `RAX_REGION` defines a Rackspace Public Cloud region (DFW, ORD, LON, ...)

## Examples

    # Add a new node to the load balancer
    - local_action:
        module: rax_clb_nodes
        load_balancer_id: 71
        address: 10.2.2.3
        port: 80
        condition: enabled
        type: primary
        wait: yes
        credentials: /path/to/credentials

    # Drain connections from a node
    - local_action:
        module: rax_clb_nodes
        load_balancer_id: 71
        node_id: 410
        condition: draining
        wait: yes
        credentials: /path/to/credentials

    # Remove a node from the load balancer
    - local_action:
        module: rax_clb_nodes
        load_balancer_id: 71
        node_id: 410
        state: absent
        wait: yes
        credentials: /path/to/credentials
