I'm using that bash script and put it in the  /etc/cron.weekly folder (using UBUNTU 22.03)  #!/bin/bash # Set PATH PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin # Run the certbot container to renew the certs docker run --rm -v certbot-webroot-VOLUME:/var/www/certbot -v certbot-data-VOLUME:/etc/letsencrypt:rw certbot/certbot renew # Restart container docker restart container-WITH-WEB-SERVER # Copy cert for Portainer cat /var/lib/docker/volumes/certbot-data-VOLUME/_data/live/YOUR.DOMAIN.COM/fullchain.pem > /opt/portainer/certs/cert.pem cat /var/lib/docker/volumes/certbot-data/_data/live/YOUR.DOMAIN.COM/privkey.pem > /opt/portainer/certs/key.pem docker restart portainer PS.
