Keeping your Let's Encrypt account email up to date is essential for receiving important notifications about certificate renewals and expirations. If you're using Certbot in a Docker container, you can update your account email with a simple command.
Steps to update your email
Run the following command, replacing the volumes and john@example.org with your new email address:
sudo docker run --rm --interactive --tty \
--volume /path/to/conf:/etc/letsencrypt \
--volume /path/to/www:/var/www/certbot \
certbot/certbot --verbose update_account --email john@example.orgExplanation
--rm: Removes the container after execution--interactive --tty: Ensures an interactive session--volume: Maps your Certbot configuration and webroot directories to persist datacertbot/certbot --verbose update_account --email: Updates the registered email with Let's Encrypt
Summary
Updating your Let's Encrypt account email is a small but crucial maintenance task. Running Certbot in Docker simplifies this process, ensuring that your account stays updated without requiring local installations. Have you encountered any challenges with Certbot and email updates?
