I have nginx with following configuration:
proxy_redirect off;
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;
client_max_body_size 1g;
client_body_buffer_size 128k;
proxy_connect_timeout 120;
proxy_send_timeout 240;
proxy_read_timeout 240;
proxy_buffers 32 4k;
proxy_hide_header Strict-Transport-Security;
proxy_hide_header Content-Type;
add_header Content-Type application/json;I would like to translate my nginx config to kubernetes ingress-nginx (Ingress resource). Is there a way to implement this config using kubernetes Ingress resources? Reading ingress-nginx docs I haven't found how to map proxy_pass or multiple rewrites to Ingress resource. I would appreciate ref to some detailed doc or sample with similar config.
Yes can do it using Snippets and Custom Templates as explained here in NGINX Ingress Controller documentation by nginxinc.
Example of using Snippets via ConfigMap:
