因此，我在 Kubernetes 环境中广泛使用ingress-nginx来进行负载平衡并作为代理，但是我在禁用access_log特定站点时遇到了一些困难。
使用构建在NGINX 1.15.5之上的ingress-nginx 0.20.0我有以下入口对象。
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: kb-kibana
annotations:
kubernetes.io/ingress.class: nginx
kubernetes.io/tls-acme: "true"
nginx.ingress.kubernetes.io/auth-signin: https://oauth2.test.test.com/oauth2/start
nginx.ingress.kubernetes.io/auth-url: http://op-oauth2-proxy.control.svc.cluster.local:4180/oauth2/auth
nginx.ingress.kubernetes.io/enable-access-log: "false"
nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
nginx.ingress.kubernetes.io/secure-backends: "false"
nginx.ingress.kubernetes.io/ssl-passthrough: "false"
nginx.ingress.kubernetes.io/ssl-redirect: "true"
spec:
rules:
- host: kibana.test.com
http:
paths:
- backend:
serviceName: kb-kibana
servicePort: 5601
path: /
tls:
- hosts:
- kibana.test.com
secretName: kb-kibana-tls
这会产生以下内容nginx.conf，
server {
server_name kibana.test.com ;
listen 80;
listen [::]:80;
set $proxy_upstream_name "-";
listen 443 ssl http2;
listen [::]:443 ssl http2;

set $proxy_upstream_name "monitoring-kb-kibana-5601";
proxy_pass_request_body off;
proxy_set_header Content-Length "";
proxy_set_header Host op-oauth2-proxy.control.svc.cluster.local;

proxy_ssl_server_name on;
proxy_pass_request_headers on;
client_max_body_size 10m;
# Pass the extracted client certificate to the auth provider
set $target http://op-oauth2-proxy.control.svc.cluster.local:4180/oauth2/auth;
proxy_pass $target;
}
location / {
set $namespace "monitoring";
set $ingress_name "kb-kibana";
set $service_name "kb-kibana";
set $service_port "5601";
set $location_path "/";
rewrite_by_lua_block {
balancer.rewrite()
}
log_by_lua_block {

monitor.call()
}
if ($scheme = https) {
more_set_headers "Strict-Transport-Security: max-age=15724800; includeSubDomains";
}
access_log off;
.....
}
}
但是，尽管有access_log off;上述情况，它仍然在访问日志中记录以下内容，

这似乎是 NGINX 特有的问题，因为此时我看不出nginx.conf配置有任何问题。任何帮助表示赞赏。
