Feature: config validation for apisix in standalone mode

[polaru]

Description

As a user running apisix in standalone mode, I would like to have a way to verify the configuration before submitting it to the instance.

In my case, we're running apisix in a kubernetes deployment, using configMaps for config.yaml and apisix.yaml. I would like to be able to verify the configuration in a step of the deployment pipeline, before updating the live/production configMaps.

Can this be linked to apache/apisix#10630 ? I think it's relevant.

Thank you for mentioning this! But I think standalone doesn't work with adc, as adc uses ETCD as well. They're two different control ways. 🤔 Correct me if I'm wrong.

The other issue I linked (apache/apisix#10630) doesn't mention adc and the suggested changes don't point to adc either; it looks to me like that person was trying to implement a test function in apisix directly, like apisix test. That's why I linked it. But if that's wrong, feel free to ignore the suggestion.

Yes. Standalone and ADC are two different data sources.

ADC has supported to do validation for APISIX 3.6+. And if you're looking for validation against Standalone apisix.yaml, please refer to apache/apisix#10630.
