Suggest changes
Table of contents

The shared groups API enables creating host groups based on host filters (the same ones used in inventory) and assigning CMDB data to them.

Create group

URI:https://hub.cfengine.com/api/host-groups/shared/

Method: POST

Parameters:

  • name(string)Group name.

  • description(string)Group description.

  • priority(number)Group priority. Groups with a higher priority will take precedence in case of conflicts when merging CMDB data. (A lower number indicates higher priority, so 1 means 1st priority, 2 means 2nd most important, and so on).

  • filter(json object) Group filter object. Includes inventory filter and classes filters

    • filter(json object) Optional parameter.Inventory filter data. You can use array values for multiple filter, the logic will be AND. Format is
    • hostContextInclude(array) Optional parameter.Includes only results that concern hosts which have all specified CFEngine contexts (class) set.
    • hostContextExclude(array) Optional parameter.Excludes results that concern hosts which have specified CFEngine context (class) set. Hosts that have at least oneof the specified contexts set will be excluded from the results.
    • hostFilter(json object) Optional parameter.
    • includes(json object) Optional parameter.Object that specifies hosts to be included.
      • includeAdditionally(boolean) Default:falseDefines if hosts will be added to the results returned by inventory filters or class filters.
      • entries(json object) Filter entries object. Where the key is an entry type and the value is an array of stringsAllowed entry types:hostkey,hostname,ip,mac,ip_mask
    • excludes(json object) Optional parameter.Object that specifies hosts to be excluded.
      • entries(json object) Filter entries object. Where the key is an entry type and the value is an array of stringsAllowed entry types:hostkey,hostname,ip,mac,ip_mask
    code
    {"filter":{"filter":{"Attribute name":{"operator":"value2"}},"hostFilter":{"includes":{"includeAdditionally":false,"entries":{"ip":["192.168.56.5"],"hostkey":[],"hostname":["ubuntu-bionic"],"mac":["08:00:27:0b:a4:99","08:00:27:dd:e1:59","02:9f:d3:59:7e:90"],"ip_mask":["10.0.2.16/16"]}},"excludes":{"entries":{"ip":[],"hostkey":[],"hostname":[],"mac":[],"ip_mask":[]}}},"hostContextExclude":["class_value"],"hostContextInclude":["class_value"]}}
