# Rackspace


<!-- Code generated by gen-dns-providers; DO NOT EDIT. -->

Configuration for the [Rackspace](https://www.rackspace.com/) DNS provider.

See the [lego documentation](https://go-acme.github.io/lego/dns/rackspace/) for full details.

```yaml
letsEncrypt:
  dnsProvider: "rackspace"
  dnsCredentials:
    # RACKSPACE_API_KEY: API key
    apiKey: ""
    # RACKSPACE_USER: API user
    user: ""
    # RACKSPACE_POLLING_INTERVAL: Time between DNS propagation check in seconds (Default: 3)
    pollingInterval: ""
    # RACKSPACE_PROPAGATION_TIMEOUT: Maximum waiting time for DNS propagation in seconds (Default: 60)
    propagationTimeout: ""
    # RACKSPACE_TTL: The TTL of the TXT record used for the DNS challenge in seconds (Default: 300)
    ttl: ""
```

Credentials are passed directly to lego using strong types and are never written to the process environment.
You may also use the raw lego environment-variable names as keys instead of the normalized names.
