This ingress configuration is successfully working.

Additionally it is required that when anyone hit URL: http://example.com, it should redirect http://example.com/login permanently, so how can i achieve it?

Thanks.

You can add the annotation like

nginx.ingress.kubernetes.io/server-snippet: |
      location ~ / {
         rewrite / https://<example.com to use $host>/login permanent;
      }

if want to use the configuration snippet

nginx.ingress.kubernetes.io/configuration-snippet: |
      if ($host = 'https://example.com/') {
        return 301 https://example.com/login;
      }

or

nginx.ingress.kubernetes.io/configuration-snippet: |
         rewrite / https://example.com/login permanent;

you can use the variables also if looking instead of using the fixed value.

$request_uri, $uri, $host are few of variables you can leverage.
