Kubernetes QuickStart


You will require a Kubernetes cluster before you can create a Teamspace. If you are just evaluating Codezero, you may safely use your own cluster and project as uninstalling Codezero is pretty straight forward. Alternatively, we have provided a Sample Project for learning. Codezero and the Sample Project is lightweight and work fine on a single node 4 core cluster or a two node 2 core cluster.

If you do not have a Kubernetes cluster, here is a list of providers who provide managed Kubernetes. Most will give you more than enough credits to get the basics.

We recommend you use the service your organization uses. We have put together a short guide on using DigitalOcean and Civo as we have found these to be especially easy to get started with. The following guide assumes you want to name your cluster my-cluster and you do not wish to merge the kubeconfig into your user's default Kubernetes config.

DigitalOcean QuickStart

Everything described here can be done in the DigitalOcean Web UI however, we find that we often set up and tear down development clusters. It helps to have the setup and teardown scripted to be able to do this quickly.

Install the CLI

This assumes you have a DigitalOcean account. Once set up, follow the How to Install and Configure doctl guide.

Set Up a Cluster

Once you have doctl installed and are authenticated, the following will set up a 2 node 2 core CPU cluster:

doctl k8s cluster create my-cluster \
--update-kubeconfig=false \
--region=sfo3 \

Leave out --update-kubeconfig if you do not want the kubeconfig to be merged into you user Kubernetes config. The above assumes you would like to set up a cluster in San Francisco.


if you get this error: "422 region has insufficient capacity for requested cluster", list the regions (see below) and select the highest number slug for that region. (The sfo region has sfo1, sfo2, and sfo3 as of this writing, but at some point sfo4 may be required).

You can get a list of regions and compute sizes using:

doctl compute region list
doctl compute size list

Obtain Credentials

If you had the --update-kubeconfig=false in the cluster create command, the doctl command line will not merge the new cluster credentials into your user's default Kubernetes config.

The following command will download the kubeconfig file, and you can use it by setting the KUBECONFIG environment variable:

doctl k8s cluster kubeconfig show my-cluster > my-cluster-kubeconfig.yaml
export KUBECONFIG=$PWD/my-cluster-kubeconfig.yaml

The Kubeconfig file may be available before your cluster is ready for use.


Be sure to add *-kubeconfig.yaml and *-kubeconfig.yml to your .gitignore so you do not accidentally check in your credentials file!

Tear Down

To tear down your cluster, issue the following command:

doctl k8s cluster delete my-cluster

We have found that occasionally, DigitalOcean does not remove Volumes and Load Balancers used by the cluster. This may be so you do not lose any important data and IP Addresses. You can clear out these resources with the following commands:


Be careful with the commands below as these commands will remove resources that were not part of the Kubernetes cluster!

doctl compute load-balancer list | awk 'NR>1 { print $1 }' | xargs -I id doctl compute load-balancer delete id -f
doctl compute volume list | awk 'NR>1 { print $1 }' | xargs -I id doctl compute volume delete id -f

Civo QuickStart

As with DigitalOcean, everything described here can be done in the Civo GUI however, using the CLI makes things easier and repeatable. Civo has the added bonus of having really fast (2 minute) provisioning times.

Civo has an excellent and succinct getting started guide Kubernetes Cluster Administration Using Civo CLI. We won't repeat it here but provide a highly condensed set of scripts to get you started:

Set Up a Cluster

The following command sets up a single node cluster and installs Traefik-v2 on it which is optional.

echo 'Creating my-cluster cluster'
civo kubernetes create my-cluster -n 1 -w -a traefik2-loadbalancer

Obtain Credentials

The following script fetches and exports the credentials:

echo 'Fetching config as my-cluster-kubeconfig.yaml'
civo kubernetes config my-cluster > $PWD/my-cluster-kubeconfig.yaml
export KUBECONFIG=$PWD/my-cluster-kubeconfig.yaml

If you save the above as civo-config, You can then configure credentials anywhere you need them by running source civo-create


Be sure to add *-kubeconfig.yaml and *-kubeconfig.yml to your .gitignore so you do not accidentally check in your credentials file!

Tear Down

Tear down is quite simple:

civo kubernetes delete my-cluster -y%
