VMware System and Permission Requirements

Before installing Palette VerteX on VMware, review the following system requirements and permissions. The vSphere user account used to deploy VerteX must have the required permissions to access the proper roles and objects in vSphere.

Start by reviewing the required action items below:

  1. Create the two custom vSphere roles. Check out the Create Required Roles section to create the required roles in vSphere.

  2. Review the vSphere Permissions section to ensure the created roles have the required vSphere privileges and permissions.

  3. Create node zones and regions for your Kubernetes clusters. Refer to the Zone Tagging section to ensure that the required tags are created in vSphere to ensure proper resource allocation across fault domains.

info

The permissions listed in this page are also needed for deploying a Private Cloud Gateway (PCG) and workload cluster in vSphere through VerteX.

Create Required Roles

VerteX requires two custom roles to be created in vSphere before the installation. Refer to the Create a Custom Role guide if you need help creating a custom role in vSphere. The required custom roles are:

  • A root-level role with access to higher-level vSphere objects. This role is referred to as the spectro root role. Check out the Root-Level Role Privileges table for the list of privileges required for the root-level role.

  • A role with the required privileges for deploying VMs. This role is referred to as the Spectro role. Review the Spectro Role Privileges table for the list of privileges required for the Spectro role.

The user account you use to deploy VerteX must have access to both roles. Each vSphere object required by VerteX must have a Permission entry for the respective Spectro role. The following tables list the privileges required for the each custom role.

info

For an in-depth explanation of vSphere authorization and permissions, check out the Understanding Authorization in vSphere resource.

vSphere Permissions

The vSphere user account that deploys VerteX require access to the following vSphere objects and permissions listed in the following table. Review the vSphere objects and privileges required to ensure each role is assigned the required privileges.

Spectro Root Role Privileges

The spectro root role privileges are only applied to root objects and data center objects. Select the tab for the vSphere version you are using to view the required privileges for the spectro root role.

If the network is a Distributed Port Group under a vSphere Distributed Switch (VDS), ReadOnly access to the VDS without “Propagate to children” is required.

Spectro Role Privileges

As listed in the table, apply spectro role privileges to vSphere objects you intend to use for Palette installation. A separate table lists Spectro role privileges for VMs by category.

During the installation, images and Open Virtual Appliance (OVA) files are downloaded to the folder you selected. These images are cloned from the folder and applied VMs that deployed during the installation.

Select the tab for the vSphere version you are using to view the required privileges for the spectro role.

Zone Tagging

You can use tags to create node zones and regions for your Kubernetes clusters. The node zones and regions can be used to dynamically place Kubernetes workloads and achieve higher availability. Kubernetes nodes inherit the zone and region tags as Labels. Kubernetes workloads can use the node labels to ensure that the workloads are deployed to the correct zone and region.

The following is an example of node labels that are discovered and inherited from vSphere tags. The tag values are applied to Kubernetes nodes in vSphere.

topology.kubernetes.io/region=usdc topology.kubernetes.io/zone=zone3 failure-domain.beta.kubernetes.io/region=usdc
failure-domain.beta.kubernetes.io/zone=zone3
info

To learn more about node zones and regions, refer to the Node Zones/Regions Topology section of the Cloud Provider Interface documentation.

Zone tagging is required to install VerteX and is helpful for Kubernetes workloads deployed in vSphere clusters through VerteX if they have persistent storage needs. Use vSphere tags on data centers and compute clusters to create distinct zones in your environment. You can use vSphere Tag Categories and Tags to create zones in your vSphere environment and assign them to vSphere objects.

The zone tags you assign to your vSphere objects, such as a datacenter and clusters are applied to the Kubernetes nodes you deploy through VerteX into your vSphere environment. Kubernetes clusters deployed to other infrastructure providers, such as public cloud may have other native mechanisms for auto discovery of zones.

For example, assume a vCenter environment contains three compute clusters, cluster-1, cluster-2, and cluster-3. To support this environment you create the tag categories k8s-region and k8s-zone. The k8s-region is assigned to the datacenter, and the k8s-zone tag is assigned to the compute clusters.

The following table lists the tag values for the data center and compute clusters.

vSphere ObjectAssigned NameTag CategoryTag Value
Datacenterdc-1k8s-regionregion1
Clustercluster-1k8s-zoneaz1
Clustercluster-2k8s-zoneaz2
Clustercluster-3k8s-zoneaz3

Create a tag category and tag values for each datacenter and cluster in your environment. Use the tag categories to create zones. Use a name that is meaningful and that complies with the tag requirements listed in the following section.

Tag Requirements

The following requirements apply to tags:

  • A valid tag must consist of alphanumeric characters.

  • The tag must start and end with an alphanumeric characters.

  • The regex used for tag validation is (([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?
