AllSpark lets you connect to any Linux machine with a Kubernetes Control Plane over the internet. You'll get the experience of managing bare metal or virtual servers like if they were in the Cloud.

Important: Please note this software is experimental and should not be used for anything resembling a production workload.

• Works on any Linux machine with minimal setup
• Seamless integration, no need for complicated VPNs or firewall configuration.
• Manage your apps as if they were in the cloud.
• Expose apps to the internet using ingress resources.
• Node multi tenancy lets you group a set of nodes to a particular tenant.

On a typical Kubernetes installation you will be oriented to create your nodes over a private network, this project does the opposity and will instruct you to connect your nodes over a public network. In order for this to work all components must be configured to communicate with a public accessible API Server.

To join a node to AllSpark a simple kubeadm join is used, a node belongs to a particular tenant identified by a label: allspark.sh/tenant=<tenantname>. The api server is configured to use the PodNodeSelector admission controller which gives the ability for all pods of a particular namespace to be schedulled on a group of nodes matching a especific selector.

An operator manages tunnels for tenants, when the connection is established it's possible to reach the nodes executing exec, attach, logs and port-forward commands.

Exposing applications could be performed using ingress resources, which also uses tunnels to proxy an app on a private node to the internet.

A demo will be available soon!
