Installation Steps#

Start a fresh Ubuntu 18.04/20.04/22.04 VM with ports 443 and 80 open. Then execute the following:

sudo su -
wget && chmod u+x && ./

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 to 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.

Service Example endpoint
Auth server https://FQDN/.well-known/openid-configuration
fido2 https://FQDN/.well-known/fido2-configuration
scim https://FQDN/.well-known/scim-configuration

Configure Janssen#

You can use the TUI to configure Janssen components. The TUI calls the Config API to perform ad hoc configuration.
