vSphere Create a VM Template

You must have at least one image before creating a new cluster. As long as you have an image, this step in your configuration is not required each time since that image can be used to spin up a new cluster. However, if you need different images for different environments or providers, you will need to create a new custom image.

The Konvoy Image Builder (KIB) uses the values in image.yaml and the input base OS image to create a vSphere template directly on the vCenter server. Using KIB, you can build an image without requiring access to the internet by providing an additional offline --override flag. You can use these overrides files to customize some of the components installed on your machine image. For example, you could tell KIB to install the FIPS versions of the Kubernetes components.

Create a vSphere Template for Your Cluster from a Base OS Image

Using the base OS image created in a previous procedure, DKP creates the new vSphere template directly on the vCenter server.

Set the following vSphere environment variables on the bastion VM host:

CODE

export VSPHERE_SERVER=your_vCenter_APIserver_URL
export VSPHERE_USERNAME=your_vCenter_user_name
export VSPHERE_PASSWORD=your_vCenter_password

Copy the base OS image file created in the vSphere Client to your desired location on the bastion VM host, and make a note of the path and file name.

Create an image.yaml file and add the following variables for vSphere. DKP uses this file and these variables as inputs in the next step. To customize your image.yaml file, refer to this section: Customize your Image.
⚠️ NOTE: This example is Ubuntu 20.04. You will need to replace OS name below based on your OS. See other default YAML examples for copy and paste below last step.

Create a vSphere VM template with your variation of the following command:
CODE
```
konvoy-image build images/ova/<image.yaml>
```
Any additional configurations can be added to this command using --overrides flags as shown below:
1. Any credential overrides: --overrides overrides.yaml
2. for FIPS, add this flag: --overrides overrides/fips.yaml
3. for air-gapped, add this flag: --overrides overrides/offline-fips.yaml
The Konvoy Image Builder (KIB) uses the values in image.yaml and the input base OS image to create a vSphere template directly on the vCenter server. This template contains the required artifacts needed to create a Kubernetes cluster.
When KIB provisions the OS image successfully, it creates a manifest file. The artifact_id field of this file contains the name of the AMI ID (AWS), template name (vSphere), or image name (GCP/Azure), for example:
CODE
```
{
      "name": "vsphere-clone",
      "builder_type": "vsphere-clone",
      "build_time": 1644985039,
      "files": null,
      "artifact_id": "konvoy-ova-vsphere-rhel-84-1.21.6-1644983717",
      "packer_run_uuid": "260e8110-77f8-ca94-e29e-ac7a2ae779c8",
      "custom_data": {
        "build_date": "2022-02-16T03:55:17Z",
        "build_name": "vsphere-rhel-84",
        "build_timestamp": "1644983717",
        [...]
      }
    }
```
Recommendation: Now we can now see the template created in our vCenter, it is best to rename it to dkp-<DKP_VERSION>-k8s-<K8S_VERSION>-<DISTRO>, like dkp-2.4.0-k8s-1.24.6-ubuntu to keep templates organized.
Next steps are to deploy a DKP cluster using your vSphere template.

Create a Kubernetes Bootstrap Cluster to enable creating your vSphere cluster and moving CAPI objects to it.

Specific to VMware Cloud Director

For storage, the VCD Provider must follow Create a Base OS image in vSphere vCenter when they create the KIB base image. In VCD, the base image determines the minimum storage available for the VM.
