Go client for configuring Citrix ADC

About

The NITRO API is the REST-like API to the Citrix ADC (aka NetScaler). This project provides a Golang SDK that can be used to make configuration API calls to a Citrix ADC.

Deprecation Notice

The project has an official home at https://github.com/citrix/adc-nitro-go where updates will continue. There will be no more updates to this repo.

Versioning

The repository uses tags to identify which version of the NITRO API is used to generate the config packages.

The version scheme follows that of Citrix ADC versioning.

For example the tag v12.1.50.12 signifies that the jsonconfig files and the generated config files are taken from the same Citrix ADC version. In this instance it is Citrix ADC version 12.1 build 50.12 .

You can checkout a specific tag or download the corresponding release if you would like to use some version of the API other than the one pointed to by the master branch.

Usage

Import the SDK from github.com/chiradeep/go-nitro/netscaler. Config objects are available at github.com/chiradeep/go-nitro/config. Instantiate a client using NewNitroClient. To initialize the client from environment variables:

export NS_URL=http://<ip-address>
export NS_LOGIN=<netscaler-username>
export NS_PASSWORD=<netscaler-password>

Config object types can be passed in as strings ("lbvserver"), or looked up from netscaler.<config object type>.Type() The general pattern for NetScaler config objects is some combination of AddResource, UpdateResource, BindResource, UnbindResource and DeleteResource. See the NITRO REST docs for more information.

Example

package main

import (
        "github.com/chiradeep/go-nitro/config/lb"
        "github.com/chiradeep/go-nitro/netscaler"
)

function main() {
        client, _ := netscaler.NewNitroClientFromEnv()
        lb1 := lb.Lbvserver{
                Name:        "sample_lb",
                Ipv46:       "10.71.136.50",
                Lbmethod:    "ROUNDROBIN",
                Servicetype: "HTTP",
                Port:        8000,
        }
        result, err := client.AddResource(netscaler.Lbvserver.Type(), "sample_lb", &lb1)
        if err == nil {
            client.SaveConfig()
        }
}

Building

The structs for the config objects under config/ used to be generated from JSON declarations in jsonconfig. The JSON itself is generated by reverse engineering the official NITRO Java SDK (see https://github.com/chiradeep/json-nitro). From 13.0, the go structs are generated and checked in directly to the repository. From 13.0-76.31 the stats directory contain the structs for the stats API.

Unit Tests

The unit tests are invoked with make unit. Note that they are actually functional tests and need a running NetScaler. The tests also need the environment variables NS_URL, NS_LOGIN and NS_PASSWORD to be set.

Using HTTPS

If you specify https in the URL then the client will use HTTPS. By default it will verify the presented certificate. If you want to use the default or self-signed certificates without verification, specify sslVerify=false in the constructor NewNitroClientFromParams or set the environment variable NS_SSLVERIFY to false and use the NewNitroClientFromEnv constructor

TODO

Some REST operations are not yet supported:

• Pagination & filtering
• Count
• Unset
• Rename
• SSL Certificate operations:
  • Link/Unlink
  • Import
