hcloud_kube

A simple collection of scripts for bootstrapping a simply k8s cluster on Hetzner Cloud.

Dependencies

You'll need:

• hcloud
• kubectl
• Other pretty standard linux utils (Bash, SSH, etc)

Quickstart

Create a kubernetes cluster with 2 CX21 nodes:

$ export HCLOUD_TOKEN=<api token>
$ ./hcloud_kube -t cx21 -n 2

Usage

1. Create a new project

2. Create a new API token in the project

3. Create a local environment variable HCLOUD_TOKEN with the value of the token.

   $ export HCLOUD_TOKEN=<api token>

4. Run the hcloud script

   $ ./hcloud_kube

5. You can then copy the kube admin config

   $ cp /tmp/hcloud_kube/admin.conf ~/.kube/config

6. You probably also want to save the generated ssh keys (in case you want to ssh in later)

   $ cp /tmp/hcloud_kube/provision_key* ~

Configuration

Command line options

• -t TYPE (default: cx21)

  The hetzner instance type for each node.

• -n COUNT (default: 0)

  The number of hetzner workers to provision.

  If set to 0, the master node is tainted to accept pods.

For additional configuration, dive in, and edit the script - it's meant to be built upon.
