and this is the code in 1.7 that was working:

i am creating the certificate with open SSL:

openssl req -x509 -newkey rsa:4096 -sha256 -nodes -keyout tls.key -out xls.crt -subj "/CN=BLABLABLA" -days 365

kubectl create secret tls certname --key=tls.key --cert=xls.crt -n develop

i dont see any error in the traefik pod
I am missing something? thanks in advance

Use 3 backticks in front and after code. It improves readability and in yaml ever space matters.

I just uploaded a few screenshots, thanks!

Here is an image for you:

which results in

code
  with correct spacing

which is readable on every device :smiley:

Done it ! i didnt know that! thanks!

Did you read this Traefik blog post (link)?

We don’t use k8s, so I know little about the k8s config. To me it seems strange that you have an ingress on websecure that uses http-to-https middlewares.

yes, i even tried doing this without the middleware part, but i got the same result:

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: whoami
  namespace: dev
spec:
  entryPoints:
    - websecure
  routes:
  - kind: Rule
    match: Host(`whoami.local`)
    services:
    - name: whoami
      port: 80
  tls:
    secretName: whoami-secret
8

Did you create the secret in k8s?

kubectl create secret generic whoami-secret --from-file=tls.crt=./server.crt --from-file=tls.key=./server.key --namespace dev secret/whoami-secret created

Enable and check Traefik debug log.

Finally i was able to make it work, by some unknown reason it is not working with these commands:
openssl req -x509 -newkey rsa:4096 -sha256 -nodes -keyout tls.key -out xls.crt -subj "/CN=blablabla" -days 365
kubectl create secret tls certificate-bitcow --key=tls.key --cert=xls.crt -n qa
I tried again with the one with the whoami app that u send me on that post and its working. Weird, its works great on 1.7.
Thanks a lot!
