Kubernetes

Kubernetes is the standard container orchestration tool.

On the TF grid, Kubernetes clusters can be deployed out of the box. We have implemented K3S, a full-blown Kubernetes offering that uses only half of the memory footprint. It is packaged as a single binary and made more lightweight to run workloads in resource-constrained locations (fits e.g. IoT, edge, ARM workloads).

Make sure you have a wallet
Click on the Kubernetes tab

Configs tab

Name: Your Kubernetes Cluster name.
Cluster Token: It's used for authentication between your worker nodes and master node. You could use the auto-generated one or type your own.

Master and Workers tabs

Currently, we only support "single-master-multi-worker" k8s clusters. So you could always add more than one worker node by clicking on the + in the Worker tab.

Kubeconfig

Once the cluster is ready, you can SSH into the cluster using ssh root@IP

IP can be the public IP or the planetary network IP

Onced connected via SSH, you can execute commands on the cluster like kubectl get nodes, and to get the kubeconfig, you can find it in /root/.kube/config

if it doesn't exist in /root/.kube/config it can be in /etc/rancher/k3s/k3s.yaml

example:

root@WR768dbf76:~# cat /root/.kube/config 
apiVersion: v1

If you want to use kubectl through another machine, you need to change the line server: https://127.0.0.1:6443 to be server: https://PLANETARYIP_OR_PUBLICIP/6443 replace PLANETARYIP_OR_PUBLICIP with the IP you want to reach th cluster through.
