【Fault conditions】
The ingress-controller was replaced in the online k8s cluster, and after TLS was added, the original POST request interface was converted into a GET request. As a result, the business service prompted "GET request is not supported".
【Solution】
Add in the ingress configuration file:
ingress.kubernetes.io/ssl-redirect: 'false'or
nginx.ingress.kubernetes.io/ssl-redirect: 'false'The setting methods of different versions are different, mine is the first one that takes effect.
In addition, there are other configurations, such as: 413 Request Entity Too Large nginx/1.19
This is also different in different versions, set to:
nginx.org/client-max-body-size: 100m
或者
nginx.ingress.kubernetes.io/proxy-body-size: "100m"
