Deploy to a Kubernetes cluster on Linode via Github Actions

I recently decided to start working on a small side project, whereby I wanted to automate the deployment so that I can write code without having to think about how and when I’ll deploy the changes.

Being that I didn’t want to spend much on hosting I decided that I would host the instances on Linode (additionally they have a Sydney datacenter).

** Note: this tutorial will also work with private dockerhub repositories!

Before we get started started

In order to follow along with this tutorial, it’d be worth creating accounts with the following services/platforms:

1. Github account — the reason is because this tutorial is focused around github actions.
2. Docker hub account — this will be used to host your docker repository.
   At the time of writing they have 1 free private repository.
3. Linode account — this will be where we host our kubernetes cluster.
   You could very easily use another cloud provider if you wished such as Digital ocean.

Create a Kubernetes Cluster

We’ll start off by creating out Kubernetes cluster in Linode as it can take some time for it to provision.

To do this we’ll click the “Create” button at the top of the screen, and then select Kubernetes.
