Create Supervisor Namespaces and infrastructure resources using kubectl

As a DevOps user, you can create a Supervisor Namespace and create infrastructure resources within the namespace using CCI kubectl commands. These examples show how to create a Supervisor Namespace and add a VM to the namespace.

Prerequisites

Verify that a Automation administrator has set up the Cloud Consumption Interface infrastructure. See Setting up the Cloud Consumption Interface infrastructure using kubectl.
Verify that you are member of at least one project in Automation Service Broker.
Verify that you are at least an organization member in Automation with the Automation Service Broker User service role.
Verify that you have:
- Downloaded the CCI kubectl plug-in.
- Obtained an API token for the User service role and assigned it as a variable.
```
TOKEN='<your_API_token>'
```
- Used your token to log in to the CCI server.
See Preparing to use the Command Line Interface to perform CCI tasks.

Create a Supervisor Namespace

This example shows how to create a Supervisor Namespace named ns-for-devops-example.

Using kubectl commands, you collect information for the following resources:

Project
Region Binding
Supervisor Namespace Class Binding

Then you add the metadata and specifications to a YAML file to create the Supervisor Namespace.

Set the default context to CCI.
```
kubectl config use-context cci
```

List available projects.

kubectl get projects

The result lists the projects that you are in.

NAME          SHARED RESOURCES
cci-document   true

List the regions in cci-document.
```
kubectl get regionbinding -n cci-document
```
The result shows all the regions in the project.
```
NAME        AGE
us-docs-1   2d13h
```
List the supervisor namespace classes in cci-document.
```
kubectl get supervisornamespaceclassbinding -n cci-document
```
The result shows all the supervisor namespace classes in the project.
```
NAME         AGE
docs-class   2d13h
```

Create a YAML file for the Supervisor Namespace that you want to create. The following example creates a namespace with:

cci-document for the project.
us-docs-1 for the region.
docs-class for the namespace class.

apiVersion: infrastructure.cci.vmware.com/v1alpha1
kind: SupervisorNamespace
metadata:
  name: ns-for-devops-example
  namespace: cci-document
spec:
  description: Create_Namespace_example
  regionName: us-docs-1
  className: docs-class

With the YAML file as input, create a supervisor namespace. In this example, the YAML file is in the same directory as the kubectl application.
```
kubectl create -f Create_Supervisor_Namespace.YAML
```

Check the status of the supervisor namespace in cci-document.

kubectl describe supervisornamespace ns-for-devops-example -n cci-document

When the result shows Status: True and Type: Ready, the supervisor namespace is ready to use and appears in the UI:

For Automation Service Broker, go to Consume > Supervisor Namespace.
For Automation Assembler, go to Infrastructure > Resources > Supervisors.

  Phase:                   Created
Events:                    <none>

If you want to delete the supervisor namespace, provide the name of the namespace, the name of the project, and include the --force flag.
```
kubectl delete supervisornamespace ns-for-devops-example -n cci-document --force
```

Add a VM to the Supervisor Namespace

This example shows how to create a VM named VM-for-devops-example.

Using kubectl commands, you collect information for the following resources:

Virtual Machine Class
Virtual Machine Image
Storage Class

Then you add resource specifications to a YAML file to create the VM.

kubectl cci login --server api.mgmt.cloud.vmware.com --token $TOKEN
Logging into api.mgmt.cloud.vmware.com
Getting supervisor namespaces
Successfully logged into api.mgmt.cloud.vmware.com
Created kubeconfig contexts:
         cci
         cci:cci-document:ns-7lan
         cci:cci-document:ns-for-devops-example
         cci:supervisor:gp-namespace

Set the default context so that you do not need to specify the namespace with context in every command.
```
kubectl config use-context cci:cci-document:ns-for-devops-example
```
The result confirms that the context has been switched and every subsequent command will be in the context of cci:cci-document:ns-for-devops-example.
```
Switched to context "cci:cci-document:ns-for-devops-example".
```

List available virtual machine classes.

kubectl get virtualmachineclassess

Select one of the virtual machine classes from the result.

List available virtual machine images.

kubectl get virtualmachineimages

Select the image that you want to use.

To list available storage policies, use the command to get resource quotas.

kubectl get resourcequota

The first section of the request is the storage policy.

NAME                                 AGE     REQUEST                                                                                         LIMIT

Create a YAML file for the VM that you want to add to the Supervisor Namespace. The following example creates a VM with:

ns-for-devops-example for the namespace.
vmi-02549e2ab956621e9 for the VM image.
guaranteed-small for the VM class.
wcpglobal-storage-profile for the storage policy.

apiVersion: vmoperator.vmware.com/v1alpha1
kind: VirtualMachine
metadata:
  name: VM-for-devops-example
  namespace: ns-for-devops-example
spec:
  imageName: vmi-02549e2ab956621e9
  className: guaranteed-small  
  storageClass: wcpglobal-storage-profile  
  powerState: poweredOn

With the YAML file as input, create a VM in the supervisor namespace. In this example, the YAML file is in the same directory as the kubectl application.
```
kubectl create -f Create_VM.YAML
```

Check the status of the VM creation in ns-for-devops-example.

kubectl describe virtualmachine vm-for-devops-example -n ns-for-devops-example

When the result shows three Status: True for Type: GuestCustomization, Type: VirtualMachinePrereqReady, and Type: VirtualMachineTools , the VM has been successfully created in the supervisor namespace.
