Getting the next available network from a “\16” or any container

SBaksh · July 2019

Problem:

You have to make a few API calls to gather this information. First, you have to make an API call to return the container to get the “_ref” and then a 2nd to query “get the network”.

Solution:

We are going to use Infoblox WAPI’s “/request”, this object allows you to make more than one API calls and pass data between HTTP methods (GET, PUT, DELETE and POST).

Docs Note:

https://[gm]/wapidoc/objects/request.html

First API call:

We are looking for a “Network Container” with an “Extensible Attribute” equal to “RED” (hopefully there is just one).

curl -X GET \ 'https://[gm]/wapi/v2.7/networkcontainer?_return_fields+=extattrs&*Country:=RED' \

First Results:

[

{

"_ref": "networkcontainer/ZG5zLm5ldHdvcmtfY29udGFpbmVyJDEwLjAuMC4wLzE2LzQ1:10.0.0.0/16/Dell",

"extattrs": {

"Country": {

"value": "RED"

},

"Paul EA": {

"value": "A"

}

},

"network": "10.0.0.0/16",

"network_view": "Dell"

}

]

Second API call:

Now that we have some useful information we can use that to form the 2nd API call

Going to get the next available network /24 passing the “network” and “network view” from the previous call and update the comment with Used

curl -X POST \

'https://[gm]/wapi/v2.7/network?_return_fields+=network,comment&_return_as_object=1&_return_fields+=network,comment' \

-H 'content-type: application/json' \

-d '{

"network": "func:nextavailablenetwork:172.16.0.0/16,Dell,24",

"network_view": "Dell",

"comment": "Used"

}'

Second Results:

{

"result": {

"_ref": "network/ZG5zLm5ldHdvcmskMTcyLjE2LjUuMC8yNC80NQ:172.16.5.0/24/Dell",

"comment": "Used",

"network": "172.16.5.0/24",

"network_view": "Dell"

}

Request Call:

Now let’s look at using Request to create our own Automation process

First call in the request is a “GET” for the object “networkcontainer”, passing in the data points “network_view” is “Dell” and EA “*Country” equals to “RED” asking to return “Extensible Attributes”

curl -X POST \
https://[gm]/wapi/v2.7/request \
  -d '[
    {
        "method": "GET",
        "object": "networkcontainer",
        "data": {
            "network_view": "Dell",
            "*Country": "RED"
        },
        "args": {
            "_return_fields+": "extattrs"
        },
        "assign_state": {
            "net_ref": "network",
            "net_view": "network_view"
        }
    },
        "discard": true
    },
    {
        "method": "POST",
        "object": "network",
        "enable_substitution": true,
        "data": {
            "network": "func:nextavailablenetwork:##STATE:net_ref:##,##STATE:sif_view:##,24",
            "network_view": "##STATE:sif_view:##",
            "comment": "Used"
        }
    }
]

Request Results:

[

"network/ZG5zLm5ldHdvcmskMTAuMC4zMC4wLzI0LzQ1:10.0.30.0/24/Dell"

]
