Creating Groups

    +
    Server groups are created with the POST /pools/default/serverGroups HTTP method and URI.

    HTTP method and URI

    POST /pools/default/serverGroups

    Description

    This creates a server group. A name for the group, unique across the server, must be specified. Names cannot be longer than 64 bytes.

    Curl Syntax

    curl -X POST -u <administrator>:<password>
http://<host>:<port>/pools/default/serverGroups
-d name="<groupName>"

    Responses

    Success gives 200 OK, and returns an empty object. Specifying a name already assigned to an existing group gives 400 Bad Request, and returns an object of the form {"name": "already exists"}. Failure to authenticate gives 401 Unauthorized.

    Example

    The following request creates a new group on the cluster.

    curl -X POST -u myAdmin:myPassword \
http://10.143.190.101:8091/pools/default/serverGroups \
-d 'name="Group 3"'

    If successful, this duly creates a new, empty group; named Group 3.
