How Set-Up Automatic Update of Let's Encrypt Certificate
Today one of my website get those email from Let`s Encrypt:
Hello, Your certificate (or certificates) for the names listed below will expire in 10 days (on 18 Jul 19 17:40 +0000). Please make sure to renew your certificate before then, or visitors to your website will encounter errors. We recommend renewing certificates automatically when they have a third of their total lifetime left. For Let's Encrypt's current 90-day certificates, that means renewing 30 days before expiration. See https://letsencrypt.org/docs/integration-guide/ for details. For any questions or support, please visit https://community.letsencrypt.org/. Unfortunately, we can't provide support by email.
Tell please how I could update it and make all those processes automated?
