Script to install Letsencrypt certs non-interactively

README.md

Install SSL certificates non-interactively

Use this script as part of any installation script. I use it as part of my script for settting up a virtualhost for a domain/website on Apache

tl;dr

you need these additional flags

• --non-interactive
• --agree-tos
• --register-unsafely-without-email or --email ${SSL_EMAIL}

install_ssl.sh

SSL_EMAIL='info@mydomain.com' # if no email, use the --register-unsafely-without-email flag
DOMAINS='mydomain.com www.mydomain.com' # comma or space separated list of domains
SERVER='nginx'

installCertbot() {
  # install Let's Encrypt Certbot
  sudo apt-get update
  sudo apt-get install software-properties-common
  sudo add-apt-repository ppa:certbot/certbot
  sudo apt-get update
  sudo apt-get install python-certbot-${SERVER}
  sudo certbot --${SERVER}
}

installSSL() {
  # install SSL
  certbot --${SERVER} --non-interactive --agree-tos --email ${SSL_EMAIL} --domains ${DOMAINS}
}

installCertbot
installSSL
