Validate Compatibility#

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/v2
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.
