Installation Steps#

Start a fresh ubuntu 18.04 or 20.04 4 CPU, 16 GB RAM, and 50GB SSD VM with ports 443 and 80 open. Then execute the following

sudo su -

wget https://raw.githubusercontent.com/JanssenProject/jans/main/automation/startjanssendemo.sh && chmod u+x startjanssendemo.sh && ./startjanssendemo.sh

This will install docker, microk8s, helm and Janssen with the default settings that can be found inside values.yaml.

The installer will automatically add a record to your hosts record in the VM but if you want access the endpoints outside the VM you must map the ip of the instance running ubuntu to the FQDN you provided and then access the endpoints at your browser such in the example in the table below.
