Question

How do I redirect all my hrefs within my response to hit my new path. For e.g., my ingress file is

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-odin
  annotations:    
    nginx.ingress.kubernetes.io/rewrite-target: /$1

spec:
  rules:
  - http:
      paths:
      - path: /odin/?(.*)
        backend:
          serviceName: flask-app-tutorial
          servicePort: 8080

When I visit the page at https://mysite/odin. It works and returns back the response:

The HTML response is:

<html>
..
    <body>
        <div>
            <a href="/v0/index">Home</a>
            <a href="/v0/login">Login</a>
        </div>

    </body>
</html>

However, as you can see, the relative links are like <a href="/v0/index">Home</a>. If I click on that, it won't work since there is no link like http://mysite/v0/index. If I click on the link, I want it to go to http://mysite/odin/v0/index. Is it possible either by modifying the links in the response to have odin or if I do click on it, it looks at the source url i.e. http://mysite/odin and direct it relative to that?

Nginx Version: 1.15.10
ingress-nginx: 0.24.0

So far,I have tried the following.

nginx.ingress.kubernetes.io/configuration-snippet: |
  proxy_set_header Accept-Encoding ""; #disable compression
  sub_filter '<head>' '<head> <base href="/odin/">';


nginx.ingress.kubernetes.io/add-base-url: ":true"
nginx.ingress.kubernetes.io/app-root: /odin

nginx.ingress.kubernetes.io/use-regex: "true"

I have also tried this i.e.

 change the spec.rules.host.paths.path from /odin/?(.*) to/(odin/.*)

There may be a typo in the advice above. I think it should http instead of host.

Answer 1

我遇到了类似的问题，并且受您的问题启发，我找到了一个对我有用的解决方案。您的注释应如下所示：

nginx.ingress.kubernetes.io/configuration-snippet: |
  sub_filter_once on;
  sub_filter '<base href="/"' '<base href="/odin/"';

如您所见，sub_filter现在已启用，我使用了 base 而不是 head 。

Answer 2

即使您按照其他答案中的建议通过包含sub_filter来修复sub_filter_once on;配置代码片段，也不会起作用，因为base标签仅适用于相对路径（请参阅： https://developer.mozilla.org/en-US/docs/Web/HTML/Element/base。

app-root解决方案在技术上是正确的，但归结为与<base href=... />相同，因此对于href标签带有反斜杠也将失败。

我可以看到两种可能性：

1）您可以修复所有href标签，删除前导斜杠。如果这样做，两种解决方案都应该起作用。

2）您可以尝试将位置规则更改为- path: /(odin)?/?(.*)，并将重写注解更改为：nginx.ingress.kubernetes.io/rewrite-target: /$2（不要忘记也包含nginx.ingress.kubernetes.io/use-regex: "true"注解），它将与也是一个斜杠。

它看起来很脆弱，因为该规则现在将（几乎）匹配所有内容，并且您可以放弃使用具有不同路径前缀的NGINX散开的可能性。

对“ 2）”进行修改以使其更可行的方法是，如果/v0标签之间的前缀一致，则匹配href前缀，而不是基本匹配。
