The gitlab.com/aws-lam/gci Project is a clone of the github.com/LAMurakami/gci Repostory. My gitlab.com/LAMurakami account was created so that Projects can be cloned using https without authentication over IPv6 as well as IPv4 unlike the github.com/LAMurakami Repostories that can only be accessed over IPv6 with the IPv6 only workaround.
lam3.freeddns.org or lam1ak.duckdns.org Dynamic Domain Name Service subdomain possibly being served by the instance.
This repo contains content in the html folder and an apache2 configuration that can be implemented with:
cd /var/www; git clone https://gitlab.com/aws-lam/gci.git
sudo ln -s /var/www/gci/gci_apache2.conf /etc/apache2/sites-available/000-gci.conf
sudo a2ensite 000-gci
sudo systemctl reload apache2
If the repo contents are installed in a location other than /var/www the path in the configuration and in the instuctions would have to be modified.
