SONiC NETCONF Server

Build Instruction

Please note that the build instruction in this guide has only been tested on Ubuntu 16.04.

Pre-rerequisit

User permissions:

`sudo usermod -aG sudo $USER`
`sudo usermod -aG docker $USER`

Packages to be installed:

`sudo apt-get install git docker`

Steps to build and create an installer

1. git clone https://github.com/project-arlo/sonic-buildimage.git
2. cd sonic-buildimage/
3. sudo modprobe overlay
4. make init
5. make configure PLATFORM=broadcom
6. Run the prefetch python script to download all binaries (see below for the script).
7. To build sonic-netconf-server container:
   BLDENV=stretch make target/docker-sonic-netconf-server.gz
8. To build Debian Stretch, if not already downloaded:
   BLDENV=stretch make stretch
9. To build the ONIE installer:
   BLDENV=stretch make target/sonic-broadcom.bin

Faster builds

In order to speed up the process of build, you can prefetch the latest debian files from Azure server, and just build what you need.

Here is a python script you could use to fetch latest prebuilt objects (deb, gz, ko, etc) from SONiC Jenkins cluster:

import os
import shutil
import urllib.request
from html.parser import HTMLParser

UPSTREAM_PREFIX = 'https://sonic-jenkins.westus2.cloudapp.azure.com/job/broadcom/job/buildimage-brcm-all/lastSuccessfulBuild/artifact/'

def get_all_bins(target_path, extension):
    """Get all files matching the given extension from the target path"""
    print('Fetching %s*%s' % (target_path, extension))
    os.makedirs(target_path, exist_ok=True)

    req = urllib.request.urlopen(UPSTREAM_PREFIX + target_path)
    data = req.read().decode()

    class Downloader(HTMLParser):
        """Class to parse retrieved data, match against the given extension,
           and download the matching files to the given target directory"""
        def handle_starttag(self, tag, attrs):
            """Handle only <a> tags"""
            if tag == 'a':
                for attr, val in attrs:
                    if attr == 'href' and val.endswith(extension):
                        self.download_file(val)

        @staticmethod
        def download_file(path):
            filename = os.path.join(target_path, path)
            freq = urllib.request.urlopen(UPSTREAM_PREFIX + target_path + path)

            print('\t%s' % path)
            with open(filename, 'wb') as fp:
                shutil.copyfileobj(freq, fp)


    parser = Downloader()
    parser.feed(data)
    print()

get_all_bins('target/debs/stretch/', '.deb')
get_all_bins('target/files/stretch/', '.ko')
get_all_bins('target/python-debs/', '.deb')
get_all_bins('target/python-wheels/', '.whl')
get_all_bins('target/', '.gz')

Incremental builds

Just clean up the deb's/gz that require re-build, and build again. Here is an exmple:

To build deb file for sonic-netconf-server

BLDENV=stretch make target/debs/stretch/sonic-netconf-server_1.0-01_amd64.deb-clean
BLDENV=stretch make target/debs/stretch/sonic-netconf-server_1.0-01_amd64.deb

To build sonic-netconf-server docker alone

BLDENV=stretch make target/docker-sonic-netconf-server.gz-clean
BLDENV=stretch make target/docker-sonic-netconf-server.gz
