How do you use lego?

Through Terraform ACME provider

Detailed Description

Hello there !

We have some OVHcloud customers that are using the ability to provide the API credentials through ovh.conf file (see README) notably in OVHcloud terraform provider.

When they are also using acme provider in a plan, they need to change the way they provide the credentials since in acme, the only supported way seems to be through environment variables

This feature request would be to enable the usage of ovh.conf file in acme for the OVHcloud provider.

Hello @yomovh,

You are a product manager at OVH, and your request is for your customers, it would feel fair if you could sponsor this project.

I will do a PR to support this in any case.

That's a fair point, I will pull some strings and see what happens.

I created a PR but I need a change inside go-ovh: ovh/go-ovh#84
