Remote Nanocld 0.1.0 Statefile for Nanocl v0.17

Description

This job enables remote access to the Nanocl daemon by generating TLS certificates and creating a proxy rule. It generates a self-signed CA and server certificate, which are used to secure the connection to the Nanocl daemon. The client certificate is also generated and can be used to authenticate clients connecting to the daemon. The generated certificates are stored as secrets in Nanocl for easy integration with other services.

You can display the client certificate using the command:

BASH

nanocl secret inspect cert.client.nanocl.io
