Using VMware Tanzu Kubernetes Grid Service with VMware Cloud on Dell EMC

VMware Cloud on Dell
automates the deployment and configuration of Tanzu. After you enable Tanzu on
VMware Cloud on Dell
, the supervisor control plane VMs are automatically deployed based on the parameters, such as Workload Control Plane, Namespace Segments, and Tier-1 Gateways.

Tanzu Administration in
VMware Cloud on Dell

Tanzu Kubernetes Grid in your
VMware Cloud on Dell
SDDC is similar to TKG on-premises with NSX-T network. However, some
and
Tanzu
components are managed by VMware and therefore, a few of the on-premises administrative workflows aren't required for
Tanzu
in
VMware Cloud on Dell
.
For information about
Tanzu
administration in
VMware Cloud on Dell
, refer to the VMware Tanzu Documentation, but consider the following high-level differences when reading the VMware Tanzu documentation.

The Workload Control Plane, Namespace Segments, and Tier-1 Gateways

Each
Tanzu
namespace requires an SDDC network segment. To preserve isolation between namespaces, the workload control plane creates a Tier 1 router in your SDDC network for each
Tanzu
namespace you create. These routers, which are listed in the
Tier-1 Gateways
page of the SDDC
Networking & Security
tab handle east-west traffic between containers connected to the namespace segment, and route north-south traffic through namespace egress and ingress points. They function much like the Compute Gateway (CGW) in your SDDC, but unlike the CGW, which is created as part of the SDDC and persists for the life of the SDDC, these per-namespace tier-1 gateways are created and destroyed along with the
Tanzu
namespaces they support.

How Tanzu Activation Affects an SDDC Network

When you activate
Tanzu Kubernetes Grid
in a
VMware Cloud on Dell
SDDC, the system creates several additional Tier 1 routers for use by the Workload Control Plane. After activation, vSphere creates additional Tier 1 routers for each
Tanzu
namespace you create.
In an SDDC that uses Direct Connect, ingress and egress CIDRs are advertised to the DX connection. In an SDDC that is a member of an SDDC group, these CIDRs are advertised to the
