netscaler_servicegroup – Manage service group configuration in Netscaler

New in version 2.4.


Synopsis

  • Manage service group configuration in Netscaler.
  • This module is intended to run either on the ansible control node or a bastion (jumpserver) with access to the actual netscaler instance.

Requirements

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

  • nitro python sdk

Parameters

Parameter Choices/Defaults Comments

  • enabled
  • disabled

-

  • DISABLED
  • DNS
  • POLICY

Auto scale option for a servicegroup.

cacheable

boolean

  • no

Cache type supported by the cache server.

cip

-

  • enabled
  • disabled

Insert the Client IP header in requests forwarded to the service.

cipheader

-

Name of the HTTP header whose value must be set to the IP address of the client. Used with the Client IP parameter. If client IP insertion is enabled, and the client IP header is not specified, the value of Client IP Header parameter or the value set by the set ns config command is used as client's IP header name.

Minimum length = 1

cka

boolean

  • no
  • yes

Enable client keep-alive for the service group.

disabled

boolean

  • no

  • yes

When set to yes the service group state will be set to DISABLED.
