redxef/certbot-duckdns repository overview

⁠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 [email protected] \
    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
