## Configuration and Credentials
|
|
|
|
Credentials and DNS configuration for DNS providers must be passed through environment variables.
|
|
|
|
### Environment Variables: Value
|
|
|
|
The environment variables can reference a value.
|
|
|
|
Here is an example bash command using the Cloudflare DNS provider:
|
|
|
|
```bash
|
|
$ CLOUDFLARE_EMAIL=you@example.com \
|
|
CLOUDFLARE_API_KEY=b9841238feb177a84330febba8a83208921177bffe733 \
|
|
lego --dns cloudflare --domains www.example.com --email you@example.com run
|
|
```
|
|
|
|
### Environment Variables: File
|
|
|
|
The environment variables can reference a path to file.
|
|
|
|
In this case the name of environment variable must be suffixed by `_FILE`.
|
|
|
|
{{% notice note %}}
|
|
The file must contain only the value.
|
|
{{% /notice %}}
|
|
|
|
Here is an example bash command using the CloudFlare DNS provider:
|
|
|
|
```bash
|
|
$ cat /the/path/to/my/key
|
|
b9841238feb177a84330febba8a83208921177bffe733
|
|
|
|
$ cat /the/path/to/my/email
|
|
you@example.com
|
|
|
|
$ CLOUDFLARE_EMAIL_FILE=/the/path/to/my/email \
|
|
CLOUDFLARE_API_KEY_FILE=/the/path/to/my/key \
|
|
lego --dns cloudflare --domains www.example.com --email you@example.com run
|
|
```
|
