I've tested the traefik ciphers - weak ciphers are allowed - i would strongly recommend to change the default settings to disallow weak ciphers...

https://docs.traefik.io/https/tls/

Will be fixed next week. Is on my agenda as well.

I just added a new branch to test the new feature:

• there is a collection of default ciphers (A rating at https://www.ssllabs.com/ssltest/ )
• you can define your own set of ciphers by adding a list to ciphers: in values.yaml.

You can see the code at 05-global-ingress.yaml

After some testing (please give some feedback) I will add it to master branch

I'm testing your feature-ssl branch. I would suggest to add more settings:

minVersion: VersionTLS12
maxVersion: VersionTLS13
# optional - very strict SNI
#sniStrict: true
curvePreferences:
- CurveP521
- CurveP384
- CurveP256

Please remove "- "TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256" which is considerd to be weak.

Trying to apply your original template fails here:

❯ kubectl apply -f templates/ingress/05-global-ingress.yml
middleware.traefik.containo.us/global-redirect-http unchanged
ingressroute.traefik.containo.us/ingressroute-allredirect unchanged
error: error parsing templates/ingress/05-global-ingress.yml: error converting YAML to JSON: yaml: line 9: could not find expected ':'

This works fine:
