Teamspace Setup

Teamspaces are vanilla Kubernetes clusters with Codezero installed. The following guide will step you through registering a Teamspace and certifying it for development use. This should take about 10 minutes to complete.

Create a Codezero Hub Account​

Sign up or log in to the Codezero Hub. The onboarding wizard will guide you through creating an organization and your first Teamspace.

The Hub allows you to manage your organization, invite and administer members, and register and certify Teamspaces. You can always return to your organization and list of Teamspaces by going to the Profile menu at the top right corner of the screen.

While the Hub provides a graphical user interface equivalent to the czctl command line tool, all services run on your local machine or in the Kubernetes cluster.

Install Codezero in your Cluster​

Ensure you have access to the cluster where you want to install Codezero from your terminal, have helm and kubectl installed, and that your current context is the correct cluster.

On the Profile menu, click Settings and then select the Teamspaces tab. Click Add Teamspace to create the installation command.

Teamspace Create

To use this command copy to your clipboard using the copy button on the right side of the screen. After doing that press the Done button.

This install command contains your organization's API key. Please keep it confidential. It uses Helm to install the Codezero Space Agent. You can find the Helm charts on Codezero's GitHub.

Now paste the command into your terminal and wait for Codezero to be installed and started.

note

Additional annotations may be necessary; refer to our Codezero Helm Chart documentation and the section on Load balancer requirements below.

Load balancer requirements​

The Codezero helm chart deploys a Kubernetes service of type LoadBalancer. For Codezero to function properly the provisioned load balancer requires a public ip address and must work on OSI layer 4.

By default AWS EKS uses classic load balancers for a Kubernetes service of type LoadBalancer. In this case no additional setup is required.

However when using AWS Load Balancer Controller additional annotations need to be set on Codezero's load balancer service. This can be done via the helm chart by adding the following values:

lb:
    service:
        annotations:
            service.beta.kubernetes.io/aws-load-balancer-type: "external"
            service.beta.kubernetes.io/aws-load-balancer-nlb-target-type: "ip"
            service.beta.kubernetes.io/aws-load-balancer-scheme: "internet-facing"

Certification​

The Codezero System installs into the codezero namespace and should take less than a minute to start depending on how long it takes to provision a LoadBalancer. The codezero loadbalancer service will be ready but the cloud loadbalancer may need minutes to be fully available.

info

For example, with AWS, the kubernetes loadbalancer service will show the AWS NLB (Network Load Balancer) hostname and codezero hub will show the space as ready and certified. However, the NLB can still be in a provisioning state and network access will only work once it is fully provisioned, which can take up to 5+ minutes.

You can view the codezero pods and services using the following:

kubectl get pods,svc -n codezero

NAME                                READY   STATUS    RESTARTS   AGE
pod/loadbalancer-556d54fb4-qx6w4    1/1     Running   0          9d
pod/operator-86b9d856cb-ktqcj       1/1     Running   0          9d
pod/system-5cb47f595b-m8ppw         1/1     Running   0          9d

NAME                   TYPE           CLUSTER-IP     EXTERNAL-IP     PORT(S)                         AGE
service/codezero       LoadBalancer   10.43.95.152   xxx.x.xxx.xxx   8800:31420/TCP                  13d
service/system         ClusterIP      10.43.9.204    <none>          8800/TCP                        13d

Once ready, you should see the Certification column at hub.codezero.io/settings/spaces change to Certified and shortly thereafter, you should see an IP address (or Host Name) show up under DNS. Your Teamspace is ready for use.

Certification ensures secure communications between the Codezero System in cluster and the Hub.

You can now select the Teamspace from the Teamspace List in the navigation panel. This will take you to the Service Catalog:

Teamspace Install

Uninstalling Codezero​

Codezero may be removed from the Kubernetes cluster at any time. It is recommended that you close all Consume and Serve sessions before you begin the uninstallation.

To uninstall, run:

helm -n codezero uninstall codezero

You can then go into the Hub and delete the Teamspace.

Troubleshooting​

Upgrade Cluster / Codezero Space Agent​

Occasionally a new Codezero release requires you to Update your Codezero Space Agent (also referred to as Upgrade your Cluster)

To update your Codezero Space Agent, run the following command:

helm repo add --force-update codezero https://charts.codezero.io && helm upgrade --namespace=codezero codezero codezero/codezero`

Stuck Waiting for DNS​

The Codezero System service will fail to start if it is unable to obtain the DNS address of the cluster. Sometimes, the Kubernetes retry logic will time out before the ingress is ready. In this case, you may have to restart the System service. To do so, simply delete the System pod:

kubectl -n codezero delete pod system-<RANDOM>

Locating Codezero Residue​

Codezero does not use any Custom Resource Definitions or finalizers. If you need to lookup resources added or modified by Codezero, you can use the following kubectl commands to see if there are any active Serves in the cluster

kubectl get all --selector="app.kubernetes.io/managed-by"=codezero --all-namespaces

If you are looking for residue in a specific namespace, use:

kubectl -n <NAMESPACE> get all --selector="app.kubernetes.io/managed-by"=codezero

NOTE: You should close all Consume and Serve sessions prior to cleaning up residue in which case the Codezero System controller will perform the cleanup for you. If for whatever reason, it does not, you can remove the resources found and re-deploy your application to get back to a clean state.
