全局配置
Nginx 全局配置
官方文档：https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/configmap/
参考文档：https://rocdu.gitbook.io/ingress-nginx-docs-cn/docs/user-guide/nginx-configuration/configmap
控制器启动参数中通过标志 --configmap 指定了一个全局的 ConfigMap 对象，比如这里用于全局配置的 ConfigMap 名为 ingress-nginx-controller
containers:
- args:
- /nginx-ingress-controller
- --configmap=$(POD_NAMESPACE)/ingress-nginx-controller
......
常用配置
日志格式
官方默认配置介绍文档：https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/log-format/
参考文档：https://rocdu.gitbook.io/ingress-nginx-docs-cn/docs/user-guide/nginx-configuration/log-format
默认配置使用自定义日志记录格式来添加有关上游、响应时间和状态的附加信息：
log_format upstreaminfo
'$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" "$http_user_agent" '
'$request_length $request_time [$proxy_upstream_name] [$proxy_alternative_upstream_name] $upstream_addr '
'$upstream_response_length $upstream_response_time $upstream_status $req_id';
json 输出配置示例 1：
data:
log-format-upstream: '{"nginx_timestamp":"$time_iso8601","clientip":"$remote_addr","nginx_host":"$server_addr","host":"$http_host","request":"$request","url":"$request_uri","upstreamhost":"$upstream_addr","status":"$status","body_bytes_sent":"$body_bytes_sent","request_time":"$request_time","upstream_response_time":"$upstream_response_time","xff":"$http_x_forwarded_for","referer":"$http_referer","http_user_agent":"$http_user_agent","request_length":"$request_length","request_method":"$request_method"}'
