Enable SSL/HTTPS for Tomcat

There are a number of guides online that explain how to setup LetsEncrypt for Tomcat, all of which I found quite involved. I setup LetsEncrypt with Tomcat a while ago, so please forgive me if I've missed a step or 10 ;)

sudo add-apt-repository ppa:certbot/certbot

sudo apt-get update

sudo apt-get install python-certbot-apache

certbot --apache -d yourdomain.co.za

sudo a2enmod proxy

sudo a2enmod proxy_http

sudo nano 000-default-le-ssl.conf

Insert the following just under DocumentRoot /var/www/html:

ProxyRequests Off
ProxyPreserveHost On
ProxyPass / http://YOUR-IP-OR-DOMAIN-NAME:8080/
ProxyPassReverse / http://YOUR-IP-OR-DOMAIN-NAME:8080/

sudo service apache2 restart

You should now have Tomcat running with a LetsEncrypt SSL certificate. If you get stuck, feel free to comment and I'll be happy to assist.
