traefik ingress同样可以配置URL的重写：

下面是一个完整例子：
|
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 |
apiVersion: extensions/v1beta1 kind: Ingress metadata: annotations: kubernetes.io/ingress.class: traefik traefik.ingress.kubernetes.io/request-modifier: 'ReplacePathRegex: ^/api3/(.*) /api/$1' creationTimestamp: "2020-03-09T03:27:40Z" generation: 2 labels: app: public-fe-zhan-operation-node-qa name: public-fe-zhan-operation-node-qa-7091-2-ingress namespace: public-fe-node-qa resourceVersion: "2310342" selfLink: /apis/extensions/v1beta1/namespaces/public-fe-node-qa/ingresses/public-fe-zhan-operation-node-qa-7091-2-ingress uid: ee6f6696-61b5-11ea-a82f-52540088db9a spec: rules: - host: www.xxxx.com http: paths: - backend: serviceName: public-fe-zhan-operation-node-qa servicePort: 7091 path: /api3 |

主要是配置是下面2行，使用了正则替换重写，将/api3改写为/api:
|
1 2 3 4 |
kubernetes.io/ingress.class: traefik traefik.ingress.kubernetes.io/request-modifier: 'ReplacePathRegex: ^/api3/(.*) /api/$1' |
- traefik 2.x配置方法
|
1 2 3 4 5 6 7 8 9 |
apiVersion: traefik.containo.us/v1alpha1 kind: Middleware metadata: name: test-replacepathregex spec: replacePathRegex: regex: ^/foo/(.*) replacement: /bar/$1 |
traefik 2.x功能更为强大，比如下面的例子：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
apiVersion: traefik.containo.us/v1alpha1 kind: IngressRoute metadata: name: public-arch-ep-api-v1-tomcat-dev-ingress-route namespace: public-arch-tomcat-dev spec: entryPoints: - web routes: - match: Host(`www.xxx.com`) && Headers(`grayscale_rules_label`, `test_label`) kind: Rule services: - name: public-arch-ep-api-v1-tomcat-dev port: 8080 - match: Host(`www.xxx.com`) kind: Rule services: - name: public-arch-ep-api-tomcat-dev port: 8080 |
访问的域名为www.xxx.com时，如果带有http header grayscale_rules_label,并且值为test_label时，访问：public-arch-ep-api-v1-tomcat-dev，否则访问到：public-arch-ep-api-tomcat-dev
