In previous post, we have containerized Hugo and pushed the image to our Docker Hub registry. Now we need a Kubernetes cluster to run this container on.
There are several options, from using local kind, building your own Kubernetes cluster to multiple cloud offerings. I will be using Linode to host my Kubernetes cluster as it is a simple and cost-effective solution that allows me to run this test app, as well as to deploy load-balancers and other tools further down the line.
Creating a Linode Kubernetes Cluster
The process is very simple, browse to https://cloud.linode.com/ and create an account. Once done, follow this simple process:
- Click on Kubernetes in the left pane
- Click on Create Cluster
- Add your cluster name in Cluster Label
- Select your Region - I am using London UK
- Select Kubernetes version - I am using 1.20 on purpose
- Add nodes - I have added three 2GB Linode nodes for $30 total
The whole process takes only few minutes to complete, you should now see your cluster.
Click on your cluster to see the details and to download your Kubeconfig file. Copy the file to your .kube folder and rename it as config:
katarinabrookfield@KatsMac .kube % ls | grep config config
Please note: If you have an existing config you can merge the two files. If you have multiple clusters, make sure you set your context to the Linode cluster:
katarinabrookfield@KatsMac .kube % kubectl config get-contexts CURRENT NAME CLUSTER AUTHINFO NAMESPACE kind-kind kind-kind kind-kind * lke27049-ctx lke27049 lke27049-admin default
Verify that you can access your Kubernetes cluster by running the following command:
katarinabrookfield@KatsMac .kube % kubectl get nodes NAME STATUS ROLES AGE VERSION lke27049-39949-60a531334464 Ready <none> 19d v1.20.6 lke27049-39949-60a53133d7b2 Ready <none> 19d v1.20.6 lke27049-39949-60a53134727c Ready <none> 19d v1.20.6
We are now ready to deploy our app!
