Part 1: Create

This is Part 1 of the exercise that will focus on creating namespaces both inside and outside of the controller.

What Will You Do¶

In part 1, you will:

Create a cluster blueprint
Apply the blueprint to a cluster
Create a namespace from the controller
Create a namespace from KUBECTL

Step 1: Create Blueprint¶

In this step, we will create a custom blueprint based off the "minimal" blueprint.

Navigate to the project in your Org where your cluster is located
Select Infrastructure -> Blueprints
Click "New Blueprint"
Enter a name for the blueprint
Select "Custom Blueprint" for the Type
Click "Save"

New Blueprint

Next, create a blueprint version for this custom blueprint.

Enter the "Version Name"
Select the minimal blueprint as the base blueprint
Click "Save Changes"

New Blueprint

The blueprint and version will be created.

New Blueprint

Step 2: Apply Blueprint¶

In this step, we will apply the blueprint to an existing cluster.

Navigate to the project in your Org where the cluster is located
Select Infrastructure -> Clusters
Click the gear icon on the cluster card
Select "Update Blueprint"
Select the previosuly created blueprint
Select the blueprint version
Click "Save and Publish"

Apply Blueprint

The blueprint will begin to be applied to the cluster.

Apply Blueprint

The blueprint is now applied to the cluster.

Apply Blueprint

Step 3: Create Namespace Inside Controller¶

In this step, we will create a namespace through the UI from the controller. This namespace will be fully managed by the controller.

Navigate to the project in your Org where the cluster is located.
Select Infrastructure -> Namespaces
Click "New Namespace"
Enter a Name for the namespace
Select "Wizard" for the Type
Click "Save"

UI Namespace

Click "Save & Go To Placement"

UI Namespace

Select the cluster to create the namespace on
Click "Save & Go To Publish"

UI Namespace

Click "Publish"

The namespace is now published on the cluster.

UI Namespace

Click "Exit"

Step 4: Create Namespace Outside Controller¶

In this step, we will create a namespace through KUBECTL outside of the controller. This namespace will NOT be managed by the controller becuase it was not created by the controller nor have we enabled namespace syncronization within the blueprint.

Navigate to the project in your Org where the cluster is located.
Select Infrastructure -> Clusters
Click "Kubectl" on the cluster card
Enter the following command

kubectl create namespace kubectl-ns

Kubectl Namespace

You will see the namespace created on the cluster.

Enter the following command

kubectl get namespace

Kubectl Namespace

In the console, you will not see the namespace as it is not managed by the controller.

Navigate to the project in your Org where the cluster is located.
Select Infrastructure -> Namespaces

The newly created namespace is not listed.

Kubectl Namespace

Recap¶

Congratulations! At this point, you have successfully deployed a blueprint and created a namespace both inside and outside of the controller.
