This topic describes how to install VMware Tanzu Application Service for VMs (TAS for VMs) on vSphere with NSX-T internal networking, using the VMware NSX-T Container Plug-in for Ops Manager.

Note: These instructions have been updated to use the NSX-T Policy API, the next-generation interface for integrating with the NSX-T networking and security framework.

Overview

TAS for VMs uses a Container Network Interface (CNI) plugin to support secure and direct internal communication between containers. This plugin can be:

Prerequisites

Before deploying TAS for VMs with NSX-T networking, you must have the following:

  • An NSX-T environment with NSX-T components installed and configured, including a Tier-0 gateway (configured in Active/Passive HA mode) attached to a North-South Transport Zone and a NSX-T edge cluster. The NSX-T version must support the versions of NCP and TAS for VMs you intend to use. Verify the compatibility between NSX-T, NCP and TAS for VMs with the following documentation:

  • BOSH and Ops Manager installed and configured on vSphere. For more information, see Deploying Ops Manager on vSphere and Configuring BOSH Director on vSphere.

  • The VMware NSX-T Container Plug-in for Ops Manager tile is downloaded from VMware Tanzu Network and imported to the Ops Manager Installation Dashboard. For information about downloading and importing VMware Tanzu products to the Installation Dashboard, see Add and Import Products in Adding and Deleting Products.

  • The TAS for VMs tile is downloaded from VMware Tanzu Network and imported to the Ops Manager Installation Dashboard. The TAS for VMs tile must be in one of these states:

    • Configured but not currently deployed. You did not click Review Pending Changes, then Apply Changes on this version of TAS for VMs.
    • Deployed previously, with the Container network interface plugin field set to External in the Networking pane of the TAS for VMs tile.

    Note: Deploying TAS for VMs with its container network interface (CNI) set to Silk configures Diego Cells to use an internally-managed container network. Subsequently switching the CNI interface to External NSX-T leads to errors.

Architecture

The following diagram shows how to deploy an NSX-T machine to run TAS for VMs across multiple vSphere hardware clusters. NSX-T runs a Tier-0 (T0) gateway and multiple Tier-1 (T1) gateways, each connecting to a network within Ops Manager. Each vSphere hardware column cluster corresponds to an Availability Zone in Ops Manager:

alt-text=NSX-T Overview

When a developer pushes an app to a new org for the first time, the NSX-T plugin triggers NSX-T to create a new T1 gateway and allocate an address range for the org, on demand.

Install and Configure TAS for VMs and NSX-T

Installing NSX-T to run with TAS for VMs requires:

  1. Configure NSX-T to Integrate with TAS for VMs

  2. Enable NSX-T Mode in the BOSH Director

  3. Configure TAS for VMs for External Container Networking

  4. Install and Configure the NSX-T Tile

Set Up NSX-T to Integrate with TAS for VMs

To set up NSX-T to integrate with TAS for VMs, complete these procedures:

Configure NAT Rules

To configure Network Address Translation (NAT) rules:

  1. Create network address translation (NAT) rules to communicate with Ops Manager:
    1. Go to Networking.
    2. Go to the NAT pane.
    3. Select your T0 gateway.
    4. Click ADD NAT RULE.
    5. Add a rule for destination NAT (DNAT) with:

Configure Gateways

To configure Tier-1 (T1) gateways:

  1. Create T1 gateways for TAS for VMs, to connect from the T0 gateway. For each Ops Manager network, Infrastructure, Deployment, and so on, create a T1 gateway as follows:

    1. In the NSX-T Manager UI, go to Networking, then Tier-1 Gateways.
    2. Click ADD TIER-1 GATEWAY.
    3. Configure the gateway. Include the Edge Cluster, as it is required to enable the Load Balancer. The Infrastructure network gateway configuration looks similar to the following screenshot:

    alt-text=""

  2. Advertise the routes of the T1 gateways to the T0 gateway, so the T0 gateway can correctly route incoming requests based on their destination IP addresses:

    1. Edit your T1 Gateway and go to Route Advertisement.
    2. Activate All Connected Segments & Service Ports.
    3. Activate All LB VIP Routes. (necessary if Load Balancing service is configured).

  3. Allocate an IP block for TAS for VMs orgs.

    1. From the NSX-T Manager, navigate to Networking, then IP Address Pools, click "IP ADDRESS BLOCKS tab, and click ADD IP ADDRESS BLOCK.
    2. Enter a name (for example, TAS for VMs-container-ip-block). This IP block name is also used in the VMware NSX-T tile in the NCP section under IP Blocks of Container Networks.
    3. Enter a description, such as Subnets are allocated from this pool to each newly-created org.
    4. Enter a CIDR to allocate an address block large enough to accommodate all TAS for VMs apps. A /14 CIDR is large enough for ~1,000 Orgs with ~250 apps each. If you are planning such a large foundation, see VMware NSX-T TAS for VMs limits in the VMware documentation.

  4. Allocate an IP block for TAS for VMs orgs.

    1. From the NSX-T Manager, go to Networking, then IP Address Pools, click the IP Address Blocks tab, and click Add IP Address Block.
    2. Enter a name (for example, TAS for VMs-container-ip-block). This IP block name is also used in the VMware NSX-T tile in the NCP section under IP Blocks of Container Networks.
    3. Enter a description, such as Subnets are allocated from this pool to each newly-created org.
    4. Enter a CIDR to allocate an address block large enough to accommodate all TAS for VMs apps. A /14 CIDR is large enough for approximately 1,000 Orgs with about 250 apps each. If you are planning a large foundation, see VMware NSX-T TAS for VMs limits in the VMware documentation.

Configure Segments

  1. Create an external SNAT IP pool:

    1. Go to Networking, then IP Address Pools.
    2. Click the IP Address Pools tab and then click Add IP Address Pool.
    3. Enter a name (for example, external-ip-pool).
    4. Enter a description (for example, “IP pool that provides 1 public IP for each TAS for VMs Org”). Later, you enter this pool name, on the VMware NSX-T tile, in the NCP section, under IP Pools used to provide External (NAT) IP Addresses to Org Networks.

    5. Set a subnet of externally-routable IP addresses for future NAT IP addresses.

Install and Configure the NSX-T Container Plug-In

To install and configure the tile:

  1. If you have not already done so, download the VMware NSX-T Container Plug-in for Ops Manager tile from VMware Tanzu Network and import it to the Installation Dashboard. For instructions, see Add and Import Products. alt-text=Installation Dashboard with NSX-T tile.

    1. If you are using VMware Workspace ONE Access, formerly called VMware Identity Manager (vIDM), then select Client Certificate Authentication.

    2. Otherwise, select Basic Authentication with Username and Password and enter NSX Manager Admin Username and Admin Password credentials in the fields.

    3. NSX Manager CA Cert: Obtain this certificate from NSX-T Manager as follows:

      1. ssh into NSX-T Manager using the admin account that you created when you deployed NSX-T Manager.

      2. From the NSX-T Manager command line, run get certificate api to retrieve the certificate.

        NSX-T tile config: NSX-T Manager

  2. Open and configure the NCP (NSX-T Container Plugin) pane as follows:

    • TAS for VMs Foundation Name: If unsure, use TAS for VMs. If multiple foundations co-exist on the same NSX-T Manager, choose a unique string, such as TAS for VMs-beta. NCP creates artifacts, such as T1 gateways and prefixes their names with this string for easy identification.
    • Overlay Transport Zone: A uniquely identifying string for the Transport Zone that you chose when you created segments for each network. This can be the name of the transport zone if no other zones in NSX-T share the same name, or else the UUID for the transport zone.
    • Tier-0 Router: A uniquely identifying string for the T0 gateway. This can be the tag string that you gave the gateway in NSX-T Manager if no other T0 gateways in NSX-T share the same name, or else the UUID for the gateway.
    • IP Blocks of Container Networks: Use the same IP block created Configure Gateways.
    • Subnet Prefix of Container Networks: Subnet mask to set the address range size for apps in a single org. Defaults to 24. This number must be higher than the mask for all TAS for VMs orgs in the NSX-T Manager New IP Block pane, to define each org’s fraction of the total TAS for VMs address space.
    • IP Pools used to provide External (NAT) IP Addresses to Org Networks: Use the same IP Pool created iin Configure Gateways.
    • Enable NSX-T Policy API: Enable this checkbox to use the new Policy API.

  3. In the NSX Node Agent pane, enable the Enable Debug Level of Logging for NSX Node Agent checkbox. alt-text=NSX-T tile config: NSX-T Node Agent

  4. Click Save and return to the Installation Dashboard.

  5. After you have configured both the TAS for VMs tile and the VMware NSX-T tile, click Review Pending Changes, then Apply Changes to deploy TAS for VMs with NSX-T networking.

Upgrade TAS for VMs with NSX-T Networking

After you have deployed TAS for VMs with NSX-T, you may need to upgrade either Ops Manager, TAS for VMs, the NSX-T Container Plug-in or NSX-T Data Center. If you upgrade one of these components, you may need to upgrade the other components as well.

For example, if you want to upgrade NSX-T Data Center, you may need to upgrade the NSX-T Container Plug-in first.

To upgrade TAS for VMs with NSX-T Networking:

  1. Plan the upgrade by determining the compatibility of NCP, NSX-T and TAS for VMs by checking the following documentation:

  2. Download the desired version of VMware NSX-T Container Plug-in for Ops Manager tile from VMware Tanzu Network.

  3. In Ops Manager, import the new version of the tile to the Installation Dashboard. For instructions, see Adding and Importing Products.

  4. Click Review Pending Changes and review your changes.

  5. Click Apply Changes.

  6. Continue with the upgrade of Ops Manager, TAS for VMs, or NSX-T Data Center. For more information, see Upgrade NCP in a Ops Manager Environment in the VMware NSX-T Data Center documentation.
