jumpserver二次开发(一)-增加项目管理功能

 jumpserver / cmdb / python/django
 

Jumpserver是全球首款完全开源的堡垒机，是符合 4A 的专业运维审计系统。 http://www.jumpserver.org

jms很好用，但是引入公司内部，也会有一些问题，比如资产导入，资产和项目关联，如何和现有cmdb打通等问题。我这里只是抛砖引玉，介绍下jms如何二次开发，做企业定制化版的jumpserver，打通DevOps系统的方法。
首先，以增加项目管理 这个功能为例，说说堡垒机如何二次开发的。

基于版本 Version 1.4.10-2 GPLv2.

一、概述

Jumpserver用的是python的django框架开发，API 采用了DRF（Django REST framework），基于CBV（Class-based views）开发模式，因此，二次开发也是比较简单的，一般先定义model，然后写api，再使用template渲染，前端基本用datatables较多。

实现效果：
项目管理

项目详情2

二、实战

项目(project)管理或者说是服务(service)管理，服务和主机是有关系的，我这里一个主机可以部署多个服务，同时一个服务也可以部署在多台主机上，所以是多堆多的关系

2.1 定义project model

2.2 修改asset model

# 增加环境定义
ENV_CHOICES = (
    ('DEV', 'dev'),
    ('TEST', 'test'),

    ('PROD', 'prod'),

environment = models.CharField(max_length=32, choices=ENV_CHOICES, default='DEV', verbose_name=_('Environment'))
# Project 和 asset 多对多关系
projects = models.ManyToManyField(Project, blank=True, verbose_name=_('Projects'), related_name='assets', )

2.3 加入全局变量中init

jumpserver/apps/assets/models/init.py 末尾增加

from .project import *

2.4 定义DRF的serializers

from rest_framework_bulk import BulkListSerializer, BulkSerializerMixin
from rest_framework import serializers
from ..models import Project, Asset


class ProjectSerializer(serializers.ModelSerializer):
    asset_count = serializers.SerializerMethodField()

    class Meta:
        model = Project
        fields = '__all__'

    @staticmethod
    def get_asset_count(obj):
        return obj.assets.count()


class ProjectAssetsSerializer(serializers.ModelSerializer):
    class Meta:
        fields = ['id', 'name', 'port']
        model = Project

    def get_field_names(self, declared_fields, info):
        fields = super().get_field_names(declared_fields, info)
        fields.extend([
            'all_assets_ip'
        ])
        return fields


class ProjectUpdateSerializer(serializers.ModelSerializer):
    """update the project, and add or delete the asset to the project"""
    assets = serializers.PrimaryKeyRelatedField(many=True, queryset=Asset.objects.all())

    class Meta:
        model = Project
        fields = ['id', 'assets']


class AssetUpdateProjectSerializer(serializers.ModelSerializer):
    projects = serializers.PrimaryKeyRelatedField(many=True, queryset=Project.objects.all())

    class Meta:
        model = Asset
        fields = ['id', 'projects']

2.5 增加URl支持

/jumpserver/apps/assets/urls/api_urls.py

10
router.register(r'projects', api.ProjectViewSet, 'project')
router.register(r'projects-assets', api.ProjectAssetsViewSet, 'project-assets-view')

# urlpatterns 增加：
    path(r'assets/<uuid:pk>/projects/',
            api.AssetUpdateProjectApi.as_view(), name='asset-update-project'),
    path(r'projects/<uuid:pk>/assets/',
            api.ProjectUpdateApi.as_view(), name='project-update-assets'),
    path('project/<uuid:pk>/assets/',
            api.ProjectAssetsListView.as_view(), name='project-assets'),

API到这里基本写完了，至于前端的一些，都是调用这些api，进行增删改查操作，详情见github

3 数据库迁移

定义了模型以后，需要执行migrate命令进行数据库变更，省了自己执行sql

1

cd jumpserver/utils
bash make_migrations.sh

4 国际化

因为我们定义的好多变量都是英文的，这里可以通过国际化手段支持中英文

# 先执行
cd jumpserver/apps
python manage.py makemessages -l zh
# 修改jumpserver/apps/locale/zh/LC_MESSAGES/django.po 的中英文对应
vim jumpserver/apps/locale/zh/LC_MESSAGES/django.po
# 修改完成后生效，完全生效需要服务重启
python manage.py compilemessages
