certbot-dns-namecom

Name.com DNS Authenticator plugin for Certbot.

This plugin automates the process of completing a dns-01 challenge by creating (and removing) TXT records using the Name.com API.

Installation

pip install certbot-dns-namecom

Credentials

Obtain an API token from your Name.com account at https://www.name.com/account/settings/api.

Create a credentials file (e.g. ~/.secrets/namecom.ini):

# Name.com API credentials used by Certbot
dns_namecom_username = myusername
dns_namecom_token = 0123456789abcdef0123456789abcdef01234567

Protect it:

chmod 600 ~/.secrets/namecom.ini

Usage

certbot certonly \
  --dns-namecom-credentials ~/.secrets/namecom.ini \
  -d example.com

Wildcard certificate:

certbot certonly \
  --dns-namecom-credentials ~/.secrets/namecom.ini \
  -d example.com \
  -d '*.example.com'

Custom propagation delay (default: 30s):

certbot certonly \
  --dns-namecom-credentials ~/.secrets/namecom.ini \
  --dns-namecom-propagation-seconds 60 \
  -d example.com

Docker

Ideally used with SWAG: linuxserver/swag image.

Use the universal-package-install mod in your docker-compose.yml:

services:
  swag:
    image: lscr.io/linuxserver/swag:latest
    environment:
      - DOCKER_MODS=linuxserver/mods:universal-package-install
      - INSTALL_PIP_PACKAGES=certbot-dns-namecom
      - VALIDATION=dns
      - DNSPLUGIN=namecom
      # ... other SWAG env vars
    volumes:
      - ./config:/config

Don't forget to create the credentials file at dns-conf/namecom.ini
