go-netbox

Package netbox provides an API 3.2 client for perimeter-81's Netbox IPAM and DCIM service.

This package assumes you are using Netbox 3.2, as the Netbox 1.0 API no longer exists. If you need support for previous Netbox versions, you can still import the corresponding release of the library. For example, run go get github.com/perimeter-81/go-netbox@netbox_v2.11 if you need compatibility with Netbox 2.11.

Using the client

The github.com/perimeter-81/go-netbox/netbox package has some convenience functions for creating clients with the most common configurations you are likely to need while connecting to NetBox. NewNetboxAt allows you to specify a hostname (including port, if you need it), and NewNetboxWithAPIKey allows you to specify both a hostname:port and API token.

import (
    "github.com/perimeter-81/go-netbox/netbox"
)
...
    c := netbox.NewNetboxAt("your.netbox.host:8000")
    // OR
    c := netbox.NewNetboxWithAPIKey("your.netbox.host:8000", "your_netbox_token")

If you specify the API key, you do not need to pass an additional authInfo to operations that need authentication, and can pass nil:

    c.Dcim.DcimDeviceTypesCreate(createRequest, nil)

If you connect to netbox via HTTPS you have to create an HTTPS configured transport:

package main

import (
	"os"

	httptransport "github.com/go-openapi/runtime/client"
	"github.com/perimeter-81/go-netbox/netbox/client"
	"github.com/perimeter-81/go-netbox/netbox/client/dcim"

	log "github.com/sirupsen/logrus"
)

func main() {
	token := os.Getenv("NETBOX_TOKEN")
	if token == "" {
		log.Fatalf("Please provide netbox API token via env var NETBOX_TOKEN")
	}

	netboxHost := os.Getenv("NETBOX_HOST")
	if netboxHost == "" {
		log.Fatalf("Please provide netbox host via env var NETBOX_HOST")
	}

	transport := httptransport.New(netboxHost, client.DefaultBasePath, []string{"https"})
	transport.DefaultAuthentication = httptransport.APIKeyAuth("Authorization", "header", "Token "+token)

	c := client.New(transport, nil)

	req := dcim.NewDcimSitesListParams()
	res, err := c.Dcim.DcimSitesList(req, nil)
	if err != nil {
		log.Fatalf("Cannot get sites list: %v", err)
	}
	log.Infof("res: %v", res)
}

Go Module support

Go 1.16+

go get github.com/perimeter-81/go-netbox

More complex client configuration

The client is generated using go-swagger. This means the generated client makes use of github.com/go-openapi/runtime/client. If you need a more complex configuration, it is probably possible with a combination of this generated client and the runtime options.

The godocs for the go-openapi/runtime/client module explain the client options in detail, including different authentication and debugging options. One thing I want to flag because it is so useful: setting the DEBUG environment variable will dump all requests to standard out.

Regenerating the client

To regenerate the client with a new or different swagger schema, first clean the existing client, then replace swagger.json and finally re-generate:

make clean
./scripts/swagger_modifier.py new_swagger_file.json
mv swagger_transformed.json swagger.json
make generate
