hi there,

i am using traefik 2.40 without any docker Environment. therefore i am configuring everything over the toml file. I am stucked at the moment how to bring Environment variables to the toml file or even hardcode them into it. Its about the configuration fro the acme challange like:

environment:

- "OVH\_ENDPOINT=[YOUR\_OWN\_VALUE]"
- "OVH\_APPLICATION\_KEY=[YOUR\_OWN\_VALUE]"
- "OVH\_APPLICATION\_SECRET=[YOUR\_OWN\_VALUE]"
- "OVH\_CONSUMER\_KEY=[YOUR\_OWN\_VALUE]"

any hints how to do that? sorry but i could not find anywhere in the help and i am guessing its easy and only caused to my lag of programming knowledge?!

regards and big thx.  
Seb

The lego driver expects these as environment variables. Set them in a script that invokes traefik or modify the systemd unit.
