|
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:**
|
|
|
|
|
|
2022-03-10 16:12:30 +01:00
|
|
|
```
|
|
|
|
|
docker run --rm \
|
|
|
|
|
-e DUCKDNS_DOMAIN=redxef \
|
|
|
|
|
-e DUCKDNS_TOKEN=<your ddns token> \
|
|
|
|
|
-e LE_EMAIL=noreply@example.com \
|
|
|
|
|
redxef/certbot-duckdns
|
|
|
|
|
```
|
|
|
|
|
|
2020-11-01 13:09:42 +01:00
|
|
|
`DUCKDNS_DOMAIN=redxef`
|
|
|
|
|
|
|
|
|
|
Yields 2 certificates, the first being for redxef.duckdns.org and the
|
2022-03-10 15:55:58 +01:00
|
|
|
second being for \*.redxef.duckdns.org. These certificates can be found
|
2020-11-01 13:09:42 +01:00
|
|
|
under the following locations respectively:
|
|
|
|
|
|
|
|
|
|
- `/etc/letsencrypt/live/redxef.duckdns.org/`
|
|
|
|
|
- `/etc/letsencrypt/live/redxef.duckdns.org-0001/`
