Deckhouse Platform on VMware vSphere
Before starting the installation, ensure you have the cloud provider quotas required to deploy your cluster..
List of required vSphere resources
- User with required set of permissions.
- Network with DHCP server and access to the Internet
- Datacenter with a tag in
k8s-region
category. - ComputeCluster with a tag in
k8s-zone
. - Datastore with required tags.
- Template — prepared VM image.
vSphere configuration
You’ll need the vSphere CLI — govc to proceed with the rest of the guide.
govc configuration
export GOVC_URL=example.com
export GOVC_USERNAME=<USER_NAME>
export GOVC_PASSWORD=<USER_PASSWORD>
export GOVC_INSECURE=1
Creating tags and tag categories
VMware vSphere doesn’t have “regions” and “zones”. It has Datacenters and ComputeClusters.
To establish relation between these and “regions”/”zones” we’ll use tags that fall into two tag categories. One for “region” tags and another for “zones tags”.
For example, if you’ve got two Datacenters with a similarly named zone in each one:
govc tags.category.create -d "Kubernetes region" k8s-region
govc tags.category.create -d "Kubernetes zone" k8s-zone
govc tags.create -d "Kubernetes Region #1" -c k8s-region test_region_1
govc tags.create -d "Kubernetes Region #2" -c k8s-region test_region_2
govc tags.create -d "Kubernetes Zone Test" -c k8s-zone test_zone
“Region” tags are attached to Datacenters:
govc tags.attach -c k8s-region test_region_1 /DC1
govc tags.attach -c k8s-region test_region_2 /DC2
“Zone” tags are attached to ComputeClusters and Datastores:
govc tags.attach -c k8s-zone test_zone /DC/host/test_cluster
govc tags.attach -c k8s-zone test_zone /DC/datastore/test_lun
Datastore tags
You can dynamically provision PVs (via PVCs) if all Datastores are present on all ESXis in a selected zone
(ComputeCluster).
StorageClasses will be created automatically for each Datastore that is tagged with region
and zone
tags.
Permissions
We’ve intentionally skipped User creation since there are many ways to authenticate a user in the vSphere.
This all-encompassing Role should be enough for all Deckhouse components. If you need a more granular Role, please contact your Deckhouse support.
You have to create a role with a following list of permissions and attach it to vCenter.

Building a VM image
- Install Packer.
- Clone the Deckhouse repository:
git clone https://github.com/deckhouse/deckhouse/
git clone https://github.com/deckhouse/deckhouse/ cd
into theee/modules/030-cloud-provider-vsphere/packer/
folder of the repository:cd deckhouse/ee/modules/030-cloud-provider-vsphere/packer/
cd deckhouse/ee/modules/030-cloud-provider-vsphere/packer/- Create a file name
vsphere.auto.pkrvars.hcl
with the following contents:vcenter_server = "<hostname or IP of a vCenter>" vcenter_username = "<username>" vcenter_password = "<password>" vcenter_cluster = "<ComputeCluster name, in which template will be created>" vcenter_datacenter = "<Datacenter name>" vcenter_resource_pool = <"ResourcePool name"> vcenter_datastore = "<Datastore name>" vcenter_folder = "<Folder name>" vm_network = "<VM network in which you will build an image>"
vcenter_server = "<hostname or IP of a vCenter>" vcenter_username = "<username>" vcenter_password = "<password>" vcenter_cluster = "<ComputeCluster name, in which template will be created>" vcenter_datacenter = "<Datacenter name>" vcenter_resource_pool = <"ResourcePool name"> vcenter_datastore = "<Datastore name>" vcenter_folder = "<Folder name>" vm_network = "<VM network in which you will build an image>" -
If your PC (the one you are running Packer from) is not located in the same network as
vm_network
(if you are connected through a tunnel), change{{ .HTTPIP }}
in the<UbuntuVersion>.pkrvars.hcl
to your PCs VPN IP:" url=http://{{ .HTTPIP }}:{{ .HTTPPort }}/preseed.cfg",
