@schlichtanders It seems traefik 3.x has changed the way redirect works. Here are some options, if you could try it would be great. Also, as always, PR most welcome.
To change the redirect behavior in this Traefik configuration, you would need to modify the ports
section under web
. Currently, it's configured to redirect HTTP traffic to HTTPS using:
ports:
web:
redirectTo:
port: websecure
Here are some options to change this:
Remove the redirect entirely:
Delete the redirectTo
section under web
. This will allow HTTP traffic without redirecting.
Change the redirect destination:
You can change the port
value under redirectTo
to redirect to a different port.
Add additional redirect options: Traefik allows more granular control over redirects. For example:
ports:
web:
redirectTo:
port: websecure
scheme: https
permanent: true
This explicitly sets the scheme to HTTPS and makes the redirect permanent (HTTP 301).
Use a custom middleware for redirection:
Instead of using the built-in redirectTo
, you could define a custom middleware for more complex redirection logic:
additionalArguments:
- "--entrypoints.web.http.middlewares=redirect-to-https@file"
# Then define the middleware in a separate file or in the dynamic configuration
http:
middlewares:
redirect-to-https:
redirectScheme:
scheme: https
permanent: true
Conditional redirection: If you want to redirect only certain requests, you could use a router with a specific rule instead of a global entrypoint redirect:
http:
routers:
my-https-redirect:
rule: "HostRegexp(`{host:.+}`)"
middlewares:
- redirect-to-https
service: noop@internal
entryPoints:
- web
Remember to adjust other parts of the configuration accordingly if you make changes to the redirection behavior. The exact approach depends on your specific requirements for handling HTTP and HTTPS traffic.

@schlichtanders Don't hesitate to resolve this the way you see fit 🙏
Thank you very much for the extensive list. This is still open and relevant for me and hope to find time over the next weeks to fix this.

I can go to the insecure

version of my site and it will load (and marked) as an insecure website.Instead it should automatically redirect to

It does not matter if they are in the same nodepool or not! So they can be in different locations and of various types. # Of course, you can choose any number of nodepools you want, with the location you want. The only constraint on the location is that you need to stay in the same network region, Europe, or the US. # For the server type, the minimum instance supported is cpx11 (just a few cents more than cx11); see https://www.hetzner.com/cloud. # IMPORTANT: Before you create your cluster, you can do anything you want with the nodepools, but you need at least one of each, control plane and agent. # Once the cluster is up and running, you can change nodepool count and even set it to 0 (in the case of the first control-plane nodepool, the minimum is 1). # You can also rename it (if the count is 0), but do not remove a nodepool from the list. # The only nodepools that are safe to remove from the list are at the end. That is due to how subnets and IPs get allocated (FILO). # You can, however, freely add other nodepools at the end of each list if you want. The maximum number of nodepools you can create combined for both lists is 255. # Also, before decreasing the count of any nodepools to 0, it's essential to drain and cordon the nodes in question. Otherwise, it will leave your cluster in a bad state. # Before initializing the cluster, you can change all parameters and add or remove any nodepools. You need at least one nodepool of each kind, control plane, and agent. # The nodepool names are entirely arbitrary, you can choose whatever you want, but no special characters or underscore, and they must be unique; only alphanumeric characters and dashes are allowed. # If you want to have a single node cluster, have one control plane nodepools with a count of 1, and one agent nodepool with a count of 0. # Please note that changing labels and taints after the first run will have no effect. If needed, you can do that through Kubernetes directly. # ⚠️ When choosing ARM cax* server types, for the moment they are only available in fsn1. # Muli-architecture clusters are OK for most use cases, as container underlying images tend to be multi-architecture too. # * Example below: control_plane_nodepools = [ { name = "control-${var.default_location}-cax41", server_type = "cax11", location = var.default_location, labels = [ # no longer needed, but may be interesting when using klipper as the load balancer # as this seems to be the final option which counts # taken from https://github.com/kube-hetzner/terraform-hcloud-kube-hetzner/issues/447#issuecomment-1350597300 # "node.kubernetes.io/exclude-from-external-load-balancers=true", ], taints = [], count = 1 # Enable automatic backups via Hetzner (default: false) # backups = true }, ] agent_nodepools = [ # Arm based nodes, currently available only in FSN location { name = "agent-${var.default_location}-cax41", server_type = "cax41", location = var.default_location, labels = [], taints = [], count = 1, } ] # Add custom control plane configuration options here. # E.g to enable monitoring for etcd, proxy etc: # control_planes_custom_config = { # etcd-expose-metrics = true, # kube-controller-manager-arg = "bind-address=0.0.0.0", # kube-proxy-arg ="metrics-bind-address=0.0.0.0", # kube-scheduler-arg = "bind-address=0.0.0.0", # } # You can enable encrypted wireguard for the CNI by setting this to "true".
