如何使用 docker 上的驱动程序在 minikube 集群中正确编写 kubernetes pod 和服务的 yaml 配置，并且有一个要求：容器的 80 端口必须可从主机访问。使用 nodePort 的解决方案无法按预期工作：

 type: NodePort 
 ports:
  - port: 80
    targetPort: 8006
  selector:
    app: blogapp

标签应用程序：博客应用程序设置在容器上。您能否显示 nginx 映像的正确配置，例如可以从主机访问端口。

我有动态条件的查询,即

select (lambda obj:obj.A = 'a' and obj.B = 'b' and ...)  

所以我为此编写代码:

def search(self,**kwargs):
        q = unicode('lambda obj:', 'utf-8')
    for field,value in kwargs.iteritems():
            value = unicode(value, 'utf-8')
            field = unicode(field, 'utf-8')
            q+=u" obj.%s == '%s' and" % (field,value

    q = q[0:q.rfind('and')] 
    res = select(q.encode('utf-8'))[:]

但我在执行函数时遇到此错误:

 tasks.search(title='?????? 1',url='test.com')
 res = select(q.encode('utf-8'))[:]
