go-netbox

go-netbox

go-netbox is —to nobody's surprise— the official Go API client for Netbox IPAM and DCIM service.

This project follows Semantic Versioning. The version of the library built for a Netbox version has the same tag, followed by the build number (an incremental integer) in the version metadata.

Installation

Use go get to add the library as a project's dependency. Do not forget to run go mod init first if necessary.

go get github.com/netbox-community/go-netbox

# Or install a specific version
go get github.com/netbox-community/go-netbox@v3.4.5+0

Note: dependencies should be managed with Go modules.

Usage

Instantiate the client

The package has some convenience functions for creating clients with the most common configurations.

package main

import (
	"log"

	"github.com/netbox-community/go-netbox/netbox"
)

func main() {
	c := netbox.NewNetboxAt("netbox.example.org:8000")
    
	// or:
	// c := netbox.NewNetboxWithAPIKey("netbox.example.org:8000", "<api-token>")

	log.Printf("%+v", c)
}

In order to consume the Netbox API with HTTP over TLS, a transport must be created.

package main

import (
	"log"

	transport "github.com/go-openapi/runtime/client"
	"github.com/netbox-community/go-netbox/netbox/client"
)

func main() {
	t := transport.New("netbox.example.org", client.DefaultBasePath, []string{"https"})

	t.DefaultAuthentication = transport.APIKeyAuth(
		"Authorization",
		"header",
		fmt.Sprintf("Token %v", "<api-token>"),
	)

	c := client.New(t, nil)

	log.Printf("%+v", c)
}

For more complex client configurations, see the documentation of github.com/go-openapi/runtime/client, the library which in turn is used by the client.

Note: setting the DEBUG environment variable will dump all requests to standard error output.

Use the client

With the client already instantiated, it is possible to consume any API feature.

For example, to list the first 100 active virtual machines:

package main

import (
	"log"

	"github.com/netbox-community/go-netbox/netbox"
	"github.com/netbox-community/go-netbox/netbox/client/virtualization"
)

var status = "active"
var pageLimit = int64(100)

func main() {
	c := netbox.NewNetboxWithAPIKey("netbox.example.org", "<api-token>")

	req := virtualization.
		NewVirtualizationVirtualMachinesListParams().
		WithStatus(&status).
		WithLimit(&pageLimit)

	// additional `authInfo` is `nil` because the API token has already been specified in the client 
	res, err := w.netbox.Virtualization.VirtualizationVirtualMachinesList(req, nil)

	if err != nil {
		log.Fatal(err)
	}

	log.Printf("%+v", res.Payload.Results)
}

See reference for more information on all possible usages.

Development

The project comes with a containerized development environment that can be used from any platform. It is only required to have Git and Docker Desktop (or, separately, Docker and Docker Compose) installed on the machine.

To start the development environment, run the following command.

make

Then, to attach a shell in the container, run the command below.

make shell

Finally, to stop the development environment, run the following command.

make down

Considerations

The library is almost entirely generated from the Netbox OpenAPI specification using go-swagger. Therefore, files under directories netbox/client and netbox/models should not be directly modified, as they will be overwritten in the next regeneration (see next section).

To fix issues in generated code, there are two options:

• Change the OpenAPI spec with pre-generation hooks (see scripts/pre-generation).
• If the above is not possible, change the generated code with post-generation hooks (see scripts/post-generation).

Regenerate the library

To update the OpenAPI specification to the latest Netbox version and regenerate the library, run the following command.

make build

If regeneration of the library is needed for a specific Netbox version other than the latest one, pass the corresponding argument.

make build NETBOX_VERSION=3.0.0

In order to obtain the OpenAPI specification, the version of netbox-docker corresponding to the given Netbox version is used. However, it is also possible to provide a specific version of netbox-docker.

make build NETBOX_VERSION=3.0.0 NETBOX_DOCKER_VERSION=1.3.1
