![Kubernetes 重写/重定向路径](https://linux22.com/image/752314/Kubernetes%20%E9%87%8D%E5%86%99%2F%E9%87%8D%E5%AE%9A%E5%90%91%E8%B7%AF%E5%BE%84.png)
我有 2 个服务使用相同的图像,但这些服务的配置不同。我希望每当我请求 /get_traits_similarity 时,它都会重定向到该服务内的 /get_similarity。有办法吗?以下是我尝试过的最新配置。
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: "/$1"
nginx.ingress.kubernetes.io/ssl-redirect: 'false'
nginx.ingress.kubernetes.io/use-regex: 'true'
nginx.ingress.kubernetes.io/app-root: /get_similarity
labels:
app.kubernetes.io/component: hashingservice
app.kubernetes.io/name: hashing-ingress
app.kubernetes.io/part-of: hashingapi
name: hashing-ingress
namespace: default
spec:
rules:
- http:
paths:
- backend:
serviceName: mediasimilarity
servicePort: 5000
path: "/(get_similarity)"
- backend:
serviceName: mediasimilarity
servicePort: 5000
path: "/(create_token)(/get_similarity){1}"
- backend:
serviceName: mediasimilarity
servicePort: 5000
path: "/(load_index)"
- backend:
serviceName: traits-mediasimilarity
servicePort: 5000
path: "/(get_traits_similarity)(/|$)(.*)"
- backend:
serviceName: traits-mediasimilarity
servicePort: 5000
path: "/(create_token)/(get_traits_similarity)(/|$)(.*){1}"
- backend:
serviceName: traits-mediasimilarity
servicePort: 5000
path: "/(load_index)"

我发现您的配置存在三个潜在问题:
注释中的拼写错误:
nginx.ingress.kubernetes.io/user-regex:
而不是nginx.ingress.kubernetes.io/use-regex:
(已修复)从 Kubernetes 1.16 版开始,API 版本中的 NetworkPolicy
extensions/v1beta1
不再提供服务。关于改写本身:
您需要正确设定目标:
nginx.ingress.kubernetes.io/rewrite-target: /get_similarity/$2
您需要在以下
spec:
部分下指定您的主机最后你需要设置你想要重写的路径:
path: /get_traits_similarity(/|$)(.*)
以下是一个例子:
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /get_similarity/$2
name: hashing-ingress
namespace: default
spec:
rules:
- host: <your_host>
http:
paths:
- backend:
serviceName: traits-mediasimilarity
servicePort: 5000
path: /get_traits_similarity(/|$)(.*)
