UpCloud Kubernetes Service examples

This repository contains sample configurations for Terraform and Kubernetes manifests to get started with our UpCloud Kubernetes Service (UKS).

Note that this repository is still evolving. Please check back once in a while and also familiarise yourself with the known issues. This repository will continue to exist while we are building better documentation with examples.

Creating your first cluster

UI

The simplest way to create a cluster is to use our Control Panel. You can do so by following these steps:

  • Log in to the UpCloud Control Panel.
  • Go to Kubernetes page using the left-hand side menu.
  • Click Create new cluster.
  • Select a Private Network for your Worker Nodes. This network should be in the same zone as the cluster you are creating. The network can not be connected to an existing cluster, can not have an attached router, and should have DHCP enabled with default route from DHCP disabled. For IP network of your SDN network, you can use for example 172.24.1.0/24.
  • Create a node group or use the default node-group; node group is a group of workers with identical image templates.
  • Name your cluster.
  • Click Create button.
  • Cluster creation will take a few minutes as worker nodes are being provisioned and a DNS record is prepared.
  • When the cluster is running, you can download your cluster's kubeconfig file; it allows you to access your cluster easily via command line with kubectl. See Exposing Services for example on deploying an Hello UKS application to your newly created cluster.

Alternatives

You can also create a cluster using the following ways:

Kubeconfig

You can get your kubeconfig by going to your cluster details page in Control Panel. Alternatively, if you use Terraform you can leverage local_file provider to create kubeconfig file after the cluster is deleted (see terraform example)
