module: rax_clb
short_description: create / delete a load balancer in Rackspace Public Cloud
description:
- creates / deletes a Rackspace Public Cloud load balancer.
version_added: "1.4"
options:
state:
description:
- Indicate desired state of the resource
choices: ['present', 'absent']
default: present
credentials:
description:
- File to find the Rackspace credentials in (ignored if C(api_key) and
C(username) are provided)
default: null
aliases: ['creds_file']
api_key:
description:
- Rackspace API key (overrides C(credentials))
username:
description:
- Rackspace username (overrides C(credentials))
name:
description:
- Name to give the load balancer
default: null
algorithm:
description:
- algorithm for the balancer being created
choices: ['RANDOM', 'LEAST_CONNECTIONS', 'ROUND_ROBIN', 'WEIGHTED_LEAST_CONNECTIONS', 'WEIGHTED_ROUND_ROBIN']
default: LEAST_CONNECTIONS
port:
description:
- Port for the balancer being created
default: 80
protocol:
description:
- Protocol for the balancer being created
choices: ['DNS_TCP', 'DNS_UDP' ,'FTP', 'HTTP', 'HTTPS', 'IMAPS', 'IMAPv4', 'LDAP', 'LDAPS', 'MYSQL', 'POP3', 'POP3S', 'SMTP', 'TCP', 'TCP_CLIENT_FIRST', 'UDP', 'UDP_STREAM', 'SFTP']
default: HTTP
timeout:
description:
- timeout for communication between the balancer and the node
default: 30
type:
description:
- type of interface for the balancer being created
choices: ['PUBLIC', 'SERVICENET']
default: PUBLIC
region:
description:
- Region to create the load balancer in
default: DFW
wait:
description:
- wait for the balancer to be in state 'running' before returning
default: "no"
choices: [ "yes", "no" ]
wait_timeout:
description:
- how long before wait gives up, in seconds
default: 300
requirements: [ "pyrax" ]
author: Christopher H. Laco, Jesse Keating
notes:
- The following environment variables can be used, C(RAX_USERNAME),
C(RAX_API_KEY), C(RAX_CREDS), C(RAX_CREDENTIALS), C(RAX_REGION).
- C(RAX_CREDENTIALS) and C(RAX_CREDS) points to a credentials file
appropriate for pyrax
- C(RAX_USERNAME) and C(RAX_API_KEY) obviate the use of a credentials file
- C(RAX_REGION) defines a Rackspace Public Cloud region (DFW, ORD, LON, ...)
