Install PaaS for debug on a single machine

This PaaS solution targets a contabo VPS or a local machine with libvirt. This one will be based on kubernetes for the containerization and dex for the k8S accesses and an oauth proxy for hosted web apps.

The optics of this tooling will follow :

  • The principle of immutable infrastructure with the idea of recreating rather than updating. Thus we will use ready linux iso to deploy the kubernetes / waypoint platform directly on a server.

  • The principle infrastructure as code (IaC) by keeping all the specification of our infrastructure in configurations and scripts. We will also use basic tests of our configurations.

For this we will use a technical base composed of :

  • rke2 A Kubernetes distribution built for production workloads. It is a CNCF-certified Kubernetes distribution that provides a simple and easy-to-use installation process, as well as a number of features that make it well-suited for production environments.
  • Nix Os to create iso images of linux machines
  • Terraform to control many cloud platforms like Gandi, Contabo, GitHub, kubernetes...

Note : Here we are only using single node mode

Secure ssh connections

After applying infrastructure to terraform you will be able to log in ssh with :

ssh user@device-name
