proxy_pass vs. rewrite in nginx ingress controller

 

	proxy_pass	rewrite
Return	200 with the content	302 with the URL to the redirected page
Content	To nginx, then the client	Second call skips nginx; returned through the redirect URL directly to client

Example of proxy_pass:

location /testing {

  proxy_pass https://news.yahoo.com/us;

}

Example of rewrite:

rewrite ^/(.*)$ https://www.newurl.com/$1-$http_x_header1 redirect

How to hook up them to nginx conf?

Add them as annotations to the Ingress. One example is:

apiVersion: networking.k8s.io/v1

kind: Ingress

metadata:

  name: my-ingress-name

  annotations:

    nginx.org/mergeable-ingress-type: "master"

    nginx.org/server-snippets: |

      rewrite ....

      location /testing {

        ....

      }

spec:

  ....

Annotation of nginx.org/rewriters:

nginx.org/rewriters: "serviceName=my-service-name rewrite=/my-new-endpoint"
