How do I resolve the error Request Header Or Cookie Too Large ? I am running into this issue because my service requires very large authentication cookies.

This error happens when HTTP headers (often big cookies) exceed NGINX’s default buffer sizes. The fix is to update all layers that handle requests:

  1. Internet-facing Okteto Ingress Controller. This is the first point of entry for requests from outside the cluster. In the Okteto Helm Chart configuration, set:

    ingress-nginx:
  controller:
    config:
      large-client-header-buffers: "4 100k"

  2. Internal Okteto Ingress Controller: This is the second layer of ingress controllers for requests that go to Development Environments ingresses. In the Okteto Helm Chart configuration, set:

    okteto-nginx:
  controller:
    config:
      large-client-header-buffers: "4 100k"

  3. Your Service’s NGINX: If your application itself is running NGINX, you’ll also need to set this directive in its config file:

    http {
  large_client_header_buffers 4 100k;
}

    To apply this, you can create a custom nginx.conf and copy it into your container image, overriding the default.
