# Certbot with duckdns wildcard certificate
Just run it with the correct environment variables and enjoy.
Because of a limitation on duckdns it is not possible to
request a certificate which works for both the domain and
wildcard subdomains. Because of this we request 2 certificates,
one for the domain and one wildcard cert.
**Example:**
```
docker run --rm \
-e DUCKDNS_DOMAIN=redxef \
-e DUCKDNS_TOKEN=<your ddns token> \
-e LE_EMAIL=noreply@example.com \
redxef/certbot-duckdns
```
`DUCKDNS_DOMAIN=redxef`
Yields 2 certificates, the first being for redxef.duckdns.org and the
second being for \*.redxef.duckdns.org. These certificates can be found
under the following locations respectively:
- `/etc/letsencrypt/live/redxef.duckdns.org/`
- `/etc/letsencrypt/live/redxef.duckdns.org-0001/`
## ENV Variables
- DUCKDNS_DOMAIN: The domain to update, ex: DUCKDNS_DOMAIN=redxef for redxef.duckdns.org
- DUCKDNS_TOKEN: Your duckdns api token
- LE_EMAIL: Your email for certificate related notifications
