## Synopsis

- Adds, modifies and removes nodes from a Rackspace Cloud Load Balancer

## Requirements

The below requirements are needed on the host that executes this module.

- pyrax

- python >= 2.6

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
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
