Rancher中ingress常用配置解决nginx问题

# 解决重写问题
# 访问带/api,proxy_pass时去掉/api
# 减少配置，增加域名利用率
# 单个配置
nginx.ingress.kubernetes.io/configuration-snippet: rewrite /api/?(.*)$ /$1 break;
# 多个配置
nginx.ingress.kubernetes.io/configuration-snippet: |-
      rewrite /api/?(.*)$ /$1 break;
      rewrite /minio/?(.*)$ /$1 break;

# 解决超载问题
nginx.ingress.kubernetes.io/proxy-body-size: 100M

# 解决504超时问题
nginx.ingress.kubernetes.io/proxy-connect-timeout: 1200
nginx.ingress.kubernetes.io/proxy-send-timeout: 1200
nginx.ingress.kubernetes.io/proxy-read-timeout: 1200

对应nginx配置

server {
        listen 80;
        server_name xxx.xxx.com;

        ignore_invalid_headers off;
        # client_max_body_size 1000m;
        proxy_buffering off;

        location / {
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
                # proxy_set_header Host $http_host;

                # proxy_connect_timeout 300;
                proxy_http_version 1.1;
                proxy_set_header Connection "";
                chunked_transfer_encoding off;

                ## 允许跨域
                add_header Access-Control-Allow-Origin *;
                add_header Access-Control-Allow-Headers X-Requested-With;
                add_header Access-Control-Allow-Methods GET,POST,OPTIONS;

                # 调优

                client_body_buffer_size 256k;
                proxy_connect_timeout 1200;
