## Introduction
|
|
|
|
Kubernetes is the standard container orchestration tool.
|
|
|
|
On the TF grid, Kubernetes clusters can be deployed out of the box. We have implemented [K3S](https://k3s.io/), 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).
|
|
|
|
## Prerequisites
|
|
|
|
- Make sure you have a [wallet](../wallet_connector.md)
|
|
- From the sidebar click on **Applications**
|
|
- Click on **Kubernetes**
|
|
|
|
## 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:
|
|
|
|
```

|

|
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.
