Go Development Environment#

Although every developer's environment is different and is subject to a personal preference, we will provide recommendations for a Go toolchain setup suitable for the development and build of NDK applications.

Environment components#

The toolchain that can be used to develop and build Go-based NDK apps consists of the following components:

  1. Go programming language - Go compiler, toolchain, and standard library
  2. Go NDK bindings - generated data access classes for gRPC based NDK service.
  3. Goreleaser - Go-focused build & release pipeline runner. Packages nFPM to produce rpm packages that can be used to install NDK agents.

Project structure#

It is recommended to use Go modules when developing applications with Go. Go modules allow for better dependency management and can be placed outside the $GOPATH directory.

Here is an example project structure that you can use for the NDK agent development:

.                            # Root of a project
├── app                      # Contains agent core logic
├── yang                     # A directory with agent YANG modules
├── agent.yml                # Agent yml config file
├── .goreleaser.yml          # Goreleaser config file
├── main.go                  # Package main that calls agent logic
├── go.mod                   # Go mod file
├── go.sum                   # Go sum file

NDK language bindings#

As explained in the NDK Architecture section, NDK is a gRPC based service. To be able to use gRPC services in a Go program the language bindings have to be generated from the source proto files.

Nokia not only provides the proto files for the SR Linux NDK service but also NDK Go language bindings.

With the provided Go bindings, the NDK can be imported in a Go project like that:

import ""
