| - Code: `porkbun` | ||
|
|
||
| Here is an example bash command using the Porkbun provider: | ||
|
|
||
| ```bash | ||
| PORKBUN_SECRET_API_KEY=xxxxxx \ | ||
| PORKBUN_PAPI_KEY=yyyyyy \ | ||
| lego --email myemail@example.com --dns porkbun --domains my.example.org run | ||
| ``` | ||
|
|
||
|
|
||
|
|
||
|
|
||
| ## Credentials | ||
|
|
||
| | Environment Variable Name | Description | | ||
| |-----------------------|-------------| | ||
| | `PORKBUN_API_KEY` | API key | | ||
| | `PORKBUN_SECRET_API_KEY` | secret API key | | ||
|
|
||
| The environment variable names can be suffixed by `_FILE` to reference a file instead of a value. | ||
| More information [here](/lego/dns/#configuration-and-credentials). | ||
|
|
||
|
|
||
| ## Additional Configuration | ||
|

||
| | Environment Variable Name | Description | | ||
| |--------------------------------|-------------| | ||
| | `PORKBUN_HTTP_TIMEOUT` | API request timeout | | ||
| | `PORKBUN_POLLING_INTERVAL` | Time between DNS propagation check | | ||
| | `PORKBUN_PROPAGATION_TIMEOUT` | Maximum waiting time for DNS propagation | | ||
| | `PORKBUN_TTL` | The TTL of the TXT record used for the DNS challenge | | ||
|
