CMDB 腾讯云部分实现

1. CMDB 腾讯云成品效果

最近由于上海疫情一直远程办公,路上通勤时间节约出来了可不能浪费.慢慢摸索做了个CMDB,从此告别用Excle管理服务器.
老年运维0基础入门Vue,自己也感觉到很多判断可能写的比较冗杂,慢慢改进吧.
先上效果图,一部分机器打了码.学渗透的小伙伴就别拿这个来练手了,网上机器多得是.请手下留情

2. 腾讯 云API

https://console.cloud.tencent.com/api/explorer
DescribeInstances 必要参数是Region,在页面上因为已经做过登录,所以不需要传AK,但通过SDK调用secret_id,secret_key就是必须的.

当发起调用后我们就能拿到了这样一个json的返回
因为我们传了InstanceIds,所以只返回了一个实例的内容.真实情况下不会单独查询,而是通过分页方式取到所有instance的清单,然后通过清单去遍历出每一个实例的配置.

      }
    ],
    "RequestId": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    "TotalCount": 1
  }
}

可以看到,Json返回了一堆数据,我们只需要去删选出几个我们感兴趣的值,通过赋值的方式一一存入对应位置.
比如:Placement.Zone,CPU,Memory,DataDisks下的DiskSize等

3. 通过python将数据整理并更新

先通过FORM传入secret_id,secret_key,region等必要参数,通过查询,保存所有实例清单.
当然可要考虑到地域没有实例的可能性.

        secret_id = request.data.get('secret_id')
        secret_key = request.data.get('secret_key')
        region_id = request.data.get('region')
        instance_result = cloud.instance_list(region_id)
        instance_list = []
        if instance_result.code == 200:
            instance_list = instance_result.InstanceSet
            if instance_result.TotalCount == 0:
                res = {
    'code': 500, 'msg': '该区域未发现云主机，请重新选择！'}
                return Response(res)
        elif instance_result.code == 500:
            res = {
    'code': 500, 'msg': '%s' %instance_result['msg']}
            return Response(res)

通过整理实例清单内容,将值一一保存更新.

        for host in instance_list:
            zone = host.Placement.Zone
            instance_id = host.InstanceId  # 实例ID
            instance_name = host.InstanceName # 机器名称
            os_version = host.OsName
            private_ip = host.PrivateIpAddresses	# 私网ip
            public_ip = host.PublicIpAddresses		# 公网IP
            cpu = "%s核" %host.CPU					# CPU核数
            memory = "%sG" %host.Memory				# 内存容量
            size = host.SystemDisk.DiskSize  # host.SystemDisk.DiskSize系统盘
            data_list = host.DataDisks       # host.DataDisks数据盘列表
            if data_list:
                for d in data_list:
                    size += d.DiskSize
            disk = str(size) + "G"
            create_date = time.strftime("%Y-%m-%d",time.strptime(host.CreatedTime, "%Y-%m-%dT%H:%M:%SZ"))
            # 创建服务器
            idc_name = zone_dict[zone]
            idc = Idc.objects.get(name=idc_name)]
            # 如果instance_id不存在才创建
            data = {
    'idc': idc,
                    'name': instance_name,
                    'hostname': instance_id,
                    'ssh_ip': private_ip[0],
                    'ssh_port': ssh_port,
                    'machine_type': 'cloud_vm',
                    'os_version': os_version,
                    'public_ip': public_ip,
                    'private_ip': private_ip,
                    'cpu_num': cpu,
                    'memory': memory,
                    'disk': disk,
                    'put_shelves_date': create_date,
                    # 'expire_datetime': expired_time,
                    'is_verified': 'verified'}
            server = Server.objects.filter(hostname=instance_id)
            if not server:
                server = Server.objects.create(**data)
                # 分组多对多
                group = ServerGroup.objects.get(id=server_group_id) # 根据id查询分组
                # 将服务器添加到分组
                server.server_group.add(group)
            else:
                server.update(**data)

4. Vue实现展示

5. axios部分

  methods: {
    
    getData()  {
    
      .....
      this.$axios.get('/cmdb/server/',{
    params: this.urlParams})
          .then(res => {
    
            // console.log(res.data);
            this.tableData = res.data.data;
            this.total =res.data.count;
          })
      },
