how to set a global https redirect

[nwsparks]

I've researched pretty exhaustively looking for a way to globally redirect all http traffic to https without finding a solution.

i am interested in how to accomplish this both via kong and via the ingress controller helm chart.

The nginx ingress controller has such an option https://docs.nginx.com/nginx-ingress-controller/configuration/global-configuration/configmap-resource/#auth-and-ssltls:~:text=False-,ssl%2Dredirect,-Sets%20an%20unconditional

and is configurable in their helm chart here https://artifacthub.io/packages/helm/ingress-nginx/ingress-nginx#:~:text=%5B%5D-,controller.config,-object

is there a way to set this that I am missing?

if anyone else stumbles across this i was able to accomplish it by setting a global plugin. there might be a more efficient function. this was just something i found.

https://docs.konghq.com/kubernetes-ingress-controller/2.11.x/guides/using-kongplugin-resource/#configuring-global-plugins

apiVersion: configuration.konghq.com/v1
kind: KongClusterPlugin
metadata:
  name: https-redirect
  annotations:
    kubernetes.io/ingress.class: kong
  labels:
    global: "true"
plugin: pre-function
config:
  functions:
  - |
    if kong.request.get_header("X-Forwarded-Proto") == "http" then
      local host = kong.request.get_host()
        if host ~= "localhost" then
        local query = kong.request.get_path_with_query()
        local url = "https://" .. host ..query
        kong.response.set_header("Location",url)
        return kong.response.exit(308,url)
        end
    end

This kind of works, but it does not redirect "Not Found" routes. This will:

apiVersion: configuration.konghq.com/v1
kind: KongClusterPlugin
metadata:
  name: https-redirect
  annotations:
    kubernetes.io/ingress.class: kong
  labels:
    global: "true"
plugin: pre-function
config:
  rewrite:
  - |
    local scheme = kong.request.get_scheme()
    if scheme == "http" then
      local host = kong.request.get_host()
      if host ~= "localhost" then
        local path = kong.request.get_path()
        local query = kong.request.get_raw_query()
        local url = "https://" .. host .. path
        if query and query ~= "" then
          url = url .. "?" .. query
        end
        kong.response.set_header("Location", url)
        return kong.response.exit(308)
      end
    end
