Question

[我为在kubernetes集群中运行的清漆缓存服务器创建了舵图，同时使用“外部IP”进行测试时产生了抛出错误，请在下面共享

共享varnish.vcl（在我的情况下为default.vcl的别名），在下面的values.yaml中。我将后端/ Web服务器硬编码为端口为“ 80”的.host =“ www.varnish-cache.org”时，有关如何解决的任何建议。我的要求是在我的情况下执行curl -IL负载平衡器入口IP），我应该使用不如上所述的缓存值（直接从后端服务器）获取响应。

任何解决方案/方法如何解决。请根据我上面的清漆（default.vcl）和values.yaml文件给出任何响应/建议。请将此作为最高优先级。

varnish.vcl：

 VCL version 5.0 is not supported so it should be 4.0 or 4.1 even though actually used Varnish version is 6
vcl 4.1;

import std;
# The minimal Varnish version is 5.0
# For SSL offloading, pass the following header in your proxy server or load balancer: 'X-Forwarded-Proto: https'
