OVH

Configuration for OVH.

  • Code: ovh
  • Since: v0.4.0

Here is an example bash command using the OVH provider:

# Application Key authentication:

OVH_APPLICATION_KEY=1234567898765432 \
OVH_APPLICATION_SECRET=b9841238feb177a84330febba8a832089 \
OVH_CONSUMER_KEY=256vfsd347245sdfg \
OVH_ENDPOINT=ovh-eu \
lego --email you@example.com --dns ovh -d '*.example.com' -d example.com run

# Or Access Token:

OVH_ACCESS_TOKEN=xxx \
OVH_ENDPOINT=ovh-eu \
lego --email you@example.com --dns ovh -d '*.example.com' -d example.com run

# Or OAuth2:

OVH_CLIENT_ID=yyy \
OVH_CLIENT_SECRET=xxx \
OVH_ENDPOINT=ovh-eu \
lego --email you@example.com --dns ovh -d '*.example.com' -d example.com run

Application Key and Secret

Application key and secret can be created by following the OVH guide.

When requesting the consumer key, the following configuration can be used to define access rights:

{
  "accessRules": [
    {
      "method": "POST",
      "path": "/domain/zone/*"
    },
    {
      "method": "DELETE",
      "path": "/domain/zone/*"
    }
  ]
}

OAuth2 Client Credentials

Another method for authentication is by using OAuth2 client credentials.

An IAM policy and service account can be created by following the OVH guide.

Following IAM policies need to be authorized for the affected domain:

  • dnsZone:apiovh:record/create
  • dnsZone:apiovh:record/delete
  • dnsZone:apiovh:refresh

Important Note

Both authentication methods cannot be used at the same time.
