我正在嘗試將 api 作為位置 (/api) 以使用 intress 設定
這是我的入口：
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ingress-dev
annotations:
# use the shared ingress-nginx
kubernetes.io/ingress.class: "nginx"
#nginx.ingress.kubernetes.io/rewrite-target: /
#nginx.ingress.kubernetes.io/app-root: /
spec:
rules:
- host: 'dev.example.com'
http:
paths:
- path: /api
pathType: Prefix
backend:
service:
name: my-ruby
port: 3000
當我 curl dev.example.com/api/check_version 我收到錯誤
I, [2021-12-01T16:43:35.776502 #13] INFO -- : [7253cca0b88503d625af527db32eb92e] Started GET "/api/check_serverr" for 10.42.1.228 at 2021-12-01 16:43:35 0300
F, [2021-12-01T16:43:35.779603 #13] FATAL -- : [7253cca0b88503d625af527db32eb92e]
[7253cca0b88503d625af527db32eb92e] ActionController::RoutingError (No route matches [GET] "/api/check_version"):
如果我添加注釋 nginx.ingress.kubernetes.io/rewrite-target:/
得到錯誤
I, [2021-12-01T16:49:11.153280 #13] INFO -- : [7832de5c07e3a173ddc86ebab5735cec] Started GET "/" for 10.42.1.228 at 2021-12-01 16:49:11 0300

[7832de5c07e3a173ddc86ebab5735cec] ActionController::RoutingError (No route matches [GET] "/"):
在這種情況下如何正確重寫？
uj5u.com熱心網友回復：
根據評論，以下內容似乎已解決此問題。
您希望/api在將請求發送到后端之前剝離該部分，因此請求/api/check_version將/check_version在它到達后端之前變為：
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$2
...<omitted>...
- path: /api(/|$)(.*)
