PowerAdmin DNS Authenticator plugin for Certbot

certbot-dns-poweradmin

PowerAdmin DNS Authenticator plugin for Certbot

This plugin automates the process of completing a dns-01 challenge by creating, and subsequently removing, TXT records using the PowerAdmin API.

Installation

pip install certbot-dns-poweradmin

PowerAdmin Configuration

Your PowerAdmin installation needs to have the API enabled. The plugin supports both API v1 and v2.

You'll need an API key with permissions to:

• List zones
• Create DNS records
• Delete DNS records

Usage

1. Create a credential file (e.g., /etc/letsencrypt/poweradmin.ini):

dns_poweradmin_api_url = https://poweradmin.example.com
dns_poweradmin_api_key = your-api-key-here
dns_poweradmin_api_version = v2

The api_version is optional and defaults to v2. Set it to v1 if your PowerAdmin installation uses the older API.

2. Secure the credential file:

chmod 600 /etc/letsencrypt/poweradmin.ini

3. Run certbot:

certbot certonly \
  --authenticator dns-poweradmin \
  --dns-poweradmin-credentials /etc/letsencrypt/poweradmin.ini \
  -d example.com

Arguments

Argument	Description
--dns-poweradmin-credentials	Path to credentials INI file (required)
--dns-poweradmin-propagation-seconds	Seconds to wait for DNS propagation (default: 120)

Examples

Get a certificate for a single domain:

certbot certonly \
  --authenticator dns-poweradmin \
  --dns-poweradmin-credentials /etc/letsencrypt/poweradmin.ini \
  -d example.com

Get a wildcard certificate:

certbot certonly \
  --authenticator dns-poweradmin \
  --dns-poweradmin-credentials /etc/letsencrypt/poweradmin.ini \
  -d example.com \
  -d "*.example.com"

With custom propagation time:

certbot certonly \
  --authenticator dns-poweradmin \
  --dns-poweradmin-credentials /etc/letsencrypt/poweradmin.ini \
  --dns-poweradmin-propagation-seconds 300 \
  -d example.com

Docker

FROM certbot/certbot
RUN pip install certbot-dns-poweradmin

Build and run:

docker build -t certbot/dns-poweradmin .

docker run --rm \
  -v /etc/letsencrypt:/etc/letsencrypt \
  -v /var/lib/letsencrypt:/var/lib/letsencrypt \
  certbot/dns-poweradmin certonly \
  --authenticator dns-poweradmin \
  --dns-poweradmin-credentials /etc/letsencrypt/poweradmin.ini \
  -d example.com

Troubleshooting

Plugin not found by certbot

If certbot plugins doesn't show dns-poweradmin, ensure both certbot and the plugin are installed in the same Python environment:

# Check where certbot is installed
which certbot

# If using system certbot but plugin in venv, either:
# Option 1: Install certbot in the same venv
pip install certbot certbot-dns-poweradmin

# Option 2: Use certbot from the venv
python -m certbot plugins

Virtual environment usage

When using a virtual environment, install both certbot and the plugin together:

python3 -m venv certbot-env
source certbot-env/bin/activate
pip install certbot certbot-dns-poweradmin

# Run certbot from the venv
certbot plugins  # should show dns-poweradmin

API connection issues

• Verify your API URL is correct and accessible
• Check that your API key has the required permissions
