比如我想去掉 url 中的 /a
1
2
3
4
| curl test.example.com/a/b/xxx/xxx
/b/xxx/xxx
|
1
2
3
| location /a/b/ {
proxy_pass http://a.default/b/;
}
|
但是这种方式需要修改 ingress nginx 开启支持 nginx 配置的功能，详情见 ingress-nginx 使用自定义的nginx配置
方法二、使用 ingress nginx 原生配置
需要去除 context path 的路径，创建专门的 ingress，比如：
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
