K8s部署Nginx（以自定义启动文件的方式）之配置文件配置+挂载

• 1、准备下面的配置文件，将该配置保存为文件名为：nginx.conf 的文件

/etc/nginx/certs/fullchain.pem 中的 /etc/nginx/certs/路径可以随便定义，目前没有什么其他的依赖，会在部署Nginx服务（Kind:Deployment）过程中通过挂载设置的方式指向 该处

worker_processes auto;

events {
    worker_connections 1024;
}

http {
    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 4096;

    default_type        application/octet-stream;

    server {
        listen 443 ssl;
        server_name www.siquanzhuanxiang.top siquanzhuanxiang.top;
        ssl_certificate      /etc/nginx/certs/fullchain.pem;
        ssl_certificate_key  /etc/nginx/certs/key.pem;

        root         /usr/share/nginx/html;

        error_page 404 /404.html;
        location = /404.html {
            }

        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
            }

            proxy_set_header    X-Forwarded-For  $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_redirect off;
            proxy_pass http://spiders-service.default.svc.cluster.local:83;
            }
        location /lark {

            proxy_set_header    Host  $host;

            proxy_set_header    X-Real-IP  $remote_addr;
            # 这个Header和X-Real-IP类似，但它在多级代理时会包含真实客户端及中间每个代理服务器的IP
            proxy_set_header    X-Forwarded-For  $proxy_add_x_forwarded_for;
            # 表示客户端真实的协议（http还是https）
            proxy_set_header X-Forwarded-Proto $scheme;
            # 指定修改被代理服务器返回的响应头中的location头域跟refresh头域数值
            # 如果使用"default"参数，将根据location和proxy_pass参数的设置来决定。
            # proxy_redirect [ default|off|redirect replacement ];
            proxy_redirect off;
            proxy_pass http://spiders-service.default.svc.cluster.local:84;
            }
        location /dappradar {
            proxy_set_header    Host  $host;
            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_redirect off;
            proxy_pass http://spiders-service.default.svc.cluster.local:87;
        }
        location /similarweb {
            proxy_set_header    Host  $host;
            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_redirect off;
            proxy_pass http://spiders-service.default.svc.cluster.local:88;
        }
    }
    server {
        listen 443 ssl;
        server_name kibana.siquanzhuanxiang.top;
        location / {
            proxy_pass http://kibana.default.svc.cluster.local:5601;
            proxy_set_header Host $host;
            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;
            }
    }
    server {
        listen 443 ssl;
        server_name k8s.siquanzhuanxiang.top;
        location / {
            proxy_pass https://kubernetes-dashboard.kubernetes-dashboard.svc.cluster.local:443;
            proxy_set_header Host $host;
            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;
            }
    }
}

路由地址解析 https://kubernetes-dashboard.kubernetes-dashboard.svc.cluster.local:443
表示：https://servicename.namespace.svc.cluster.local:暴露在命名空间内的端口

• 2、基于原始配置文件，在配置文件的目录执行下面的命令

kubectl create configmap nginx-config --from-file=nginx.conf

• 3、configmap格式化（第二步命令执行后的结果）

转发地址是通过服务名和命名空间、端口号进行拼接

• 4、修改配置文件（可选）
  • 一共有两种方式，二选一
    • 1、通过K8s dashboard面板进行修改
    • 2、通过命令kubectl edit cm nginx-config 进行修改
