Civo Setup

0b - Civo Setup

If you're constrained on resources for a local install, Kubernetes provider Civo is a great alternative since they provide free credits. The following steps are required to obtain the login credentials and setup the Civo Provided Kubernetes cluster.

✅ Step 1:

• Create an account using the Civo provided custom link for free credits without a credit card and obtain the login credentials and login with the same.

✅ Step 2:

• Obtain the API Key (login again if prompted) at Civo security to be able use the civo CLI. Lets call this <YOUR-API-KEY> and looks like below

✅ Step 3:

• Install Civo CLI

✅ Step 4:

• Add the API Key as below.

civo apikey add <ANY-NAME> <YOUR-API-KEY> 

✅ Step 5:

• Make this key current and verify that it was indeed current.

civo apikey ls

Set the default API Key to be rags +------+---------+ | Name | Default | +------+---------+ | rags | <===== | +------+---------+

✅ Step 6:

• Create a cluster called k8ssandra, without Traefik where we will install Trafeik and k8ssandra later. We also open up all ports (not recommended but OK for workshop) with the following command.

civo kubernetes create k8ssandra --size=g3.k3s.large --nodes=3 --wait -r Traefik --create-firewall all

The cluster k8ssandra (XX1c2fd7-7ee4-YY84-8fde-703a4853d5ZZ) has been created in 2 min 10 sec

✅ Step 7:

• Merge the configuration file with the following command

civo kubernetes config k8ssandra --save --merge

✅ Step 8:

Ensure that the current context is pointing to the recently created cluster with the following command.

kubectl config use-context k8ssandra
kubectl get node

Verify that you're using the right context with the following command

kubectl config get-contexts

          minikube         minikube         minikube         default

✅ Step 9:

Get information on the cluster you just created with the following command.

civo kubernetes show k8ssandra
