Apache APISIX Ingress project is a continuously actively developed project. In order to make it better, some broken changes will be added when the new version is released. For users, how to upgrade safely becomes very important.
The policy directory of this project contains these compatibility check strategies, you can use the conftest tool to check the compatibility.
Here's a quick example.
apiVersion: apisix.apache.org/v2beta3 kind: ApisixRoute metadata: name: httpbin-route spec: http: - name: rule1 match: hosts: - httpbin.org paths: - /ip exprs: - subject: scope: Header name: X-Foo op: Equal value: bar backends: - serviceName: httpbin servicePort: 80
It uses the spec.http.backend field that has been removed. Save as httpbin-route.yaml.
Use conftest for compatibility check.
$ conftest test httpbin-route.yaml FAIL - httpbin-route.yaml - main - ApisixRoute/httpbin-route: rule1 field http.backend has been removed, use http.backends instead. 2 tests, 1 passed, 0 warnings, 1 failure, 0 exceptions
Incompatible parts will generate errors.
