This topic describes how to configure BOSH Director for vSphere with NSX-T integration for VMware Tanzu Kubernetes Grid Integrated Edition (TKGI).
Before you begin this procedure, ensure that you have successfully completed all preceding steps for installing Tanzu Kubernetes Grid Integrated Edition on vSphere with NSX-T, including:
To create, delete, and modify NSX-T networking resources, Ops Manager tiles, and APIs use a VMware NSX Manager account with the Enterprise Administrator role and permissions.
Users configure Ops Manager to authenticate to NSX Manager for different purposes in different tiles:
To configure BOSH Director:
Log in to Ops Manager with the user name and password credentials that you set up in Configure Ops Manager for Tanzu Kubernetes Grid Integrated Edition.
Click the BOSH Director for vSphere tile.
To configure BOSH Director with your vCenter settings:
Select vCenter Config in BOSH Director.
Enter the following information:
Note: The FQDN for the vCenter Server cannot contain uppercase letters.
Note: The vSphere datastore type must be Datastore. Tanzu Kubernetes Grid Integrated Edition does not support the use of vSphere Datastore Clusters with or without Storage DRS. For more information, see Datastores and Datastore Clusters in the vSphere documentation.
For Networking, select NSX Networking.
Configure NSX networking as follows:
Configure the following folder names:
Note: After your initial deployment, you cannot edit the VM Folder, Template Folder, and Disk path Folder names.
To configure BOSH Director settings:
Select Director Config in BOSH Director.
In the NTP Servers (comma delimited) field, enter your NTP server addresses.
Note: The NTP server configuration only updates after VM recreation. Ensure that you select the Recreate VMs deployed by the BOSH Director check box if you modify the value of this field.
Leave the JMX Provider IP Address field blank.
Leave the Bosh HM Forwarder IP Address field blank.
Select the Enable VM Resurrector Plugin to enable BOSH Resurrector functionality.
Select Enable Post Deploy Scripts to run a post-deploy script after deployment. This script allows the job to execute additional commands against a deployment.
Note: You must enable post-deploy scripts to install Tanzu Kubernetes Grid Integrated Edition.
Select Recreate VMs deployed by the BOSH Director to force BOSH to recreate all BOSH-managed VMs on the next deploy. This process does not destroy any persistent disk data.
For typical Tanzu Kubernetes Grid Integrated Edition deployments, the default settings for all other BOSH Director configuration parameters are suitable. Optionally you can apply additional configurations to BOSH Director. See Director Config Pane in Configuring BOSH Director on vSphere in the Ops Manager documentation for details.
Note: If you need to be able to remotely access the BOSH Director VM using the BOSH CLI, and you are deploying Tanzu Kubernetes Grid Integrated Edition with NSX-T in a NAT topology, you must provide the Director Hostname for BOSH at the time of installation. See Director Config Pane in Configuring BOSH Director on vSphere in the Ops Manager documentation for details.
On vSphere with NSX-T, operators define and create Availability Zones (AZs) using vCenter clusters and resource pools. Plans defined in the TKGI tile then use these AZs to enable high availability for TKGI clusters.
The Tanzu Kubernetes Grid Integrated Edition control plane also runs in one of the AZs.
For more information on AZs in TKGI, see Availability Zones in Tanzu Kubernetes Grid Integrated Edition Architecture.
To configure Availability Zones:
Select Create Availability Zones in BOSH Director.
Use the following steps to create one or more Availability Zones for Tanzu Kubernetes Grid Integrated Edition to use:
RP-MGMT-TKGI. The jobs running in this Availability Zone share the CPU and memory resources defined by the pool.
RP-TKGI-AZ. Alternatively, specify the Cluster and the Host Group. See Using vSphere Host Group for more information.
SHOULD. This setting maintains high availability by letting TKGI restart VMs in another host group if their AZ fails. TKGI ignores this setting if the vSAN cluster has no host group configured.
You must configure and create BOSH Director networking.
Note: If you are using No-NAT with Virtual Switch (VSS/VDS) Topology, create the infrastructure network and optionally the TKGI network by following the instructions in Create Networks Pane in Configuring BOSH Director on vSphere in the Ops Manager documentation. While completing the steps in Create Networks Pane, do not create the
services network. With TKGI on NSX-T, NSX-T manages the dynamically created networks.
To configure BOSH Director networking:
Select Create Networks in BOSH Director.
Select Enable ICMP checks to enable ICMP on your networks. Ops Manager uses ICMP checks to confirm that components within your network are reachable.
Click Add Network.
Create the following network:
NET-MGMT-TKGI: Network for Ops Manager, BOSH Director, and Tanzu Kubernetes Grid Integrated Edition components. This network maps to the NSX logical switch created for the Tanzu Kubernetes Grid Integrated Edition Management Network. See Create Management Plane in Installing and Configuring NSX-T Data Center v3.0 for TKGI.
Note: NSX-T automatically creates the service network to be used by the control plane and worker nodes (VMs) for Kubernetes clusters managed by Tanzu Kubernetes Grid Integrated Edition. Do not manually create this network.
Use the following values as a guide when you define the network in BOSH. Replace the IP addresses with ranges you defined for the Create Management Plane in Installing and Configuring NSX-T Data Center v3.0 for TKGI. Reserve any IP addresses from the subnet that are already in use, such as the IP for Ops Manager and subnet gateway.
|vSphere Network Name||
|Reserved IP Ranges||
Select the AZ-MGMT Availability Zone to use with the
Note: Do not select the COMPUTE network at this point in the configuration. It will be configured at the end of the procedure.
To configure the AZs and the Network for BOSH Director:
Select Assign AZs and Networks in BOSH Director.
Use the drop-down menu to select a Singleton Availability Zone. The Ops Manager Director installs in this Availability Zone. For Tanzu Kubernetes Grid Integrated Edition, this will be the
AZ-MGMT availability zone.
Use the drop-down menu to select a Network for BOSH Director. BOSH Director runs on the Tanzu Kubernetes Grid Integrated Edition Management Plane network. Select the
To configure a BOSH Director certificate and password:
Select Security in BOSH Director.
In Trusted Certificates, enter a custom certificate authority (CA) certificate to insert into your organization’s certificate trust chain. This feature allows all BOSH-deployed components in your deployment to trust a custom root certificate.
If you are using self-signed CAs for the infrastructure components (NSX-T, vCenter), you need to add every CA of every component your deployment might connect to. In other words, the bundle must include all certificates for any component that connects to or from BOSH.
If you are using a private Docker registry, such as VMware Harbor, use this field to enter the certificate for the registry. See Integrating Harbor Registry with Tanzu Kubernetes Grid Integrated Edition for details.
Choose Generate passwords or Use default BOSH password. Use the Generate passwords option for increased security.
Click Save. To view your saved Director password, click the Credentials tab.
To configure BOSH Director DNS:
Select BOSH DNS Config in BOSH Director.
(Optional) In Excluded Recursors, enter a list of prohibited DNS recursor addresses.
(Optional) In Recursor Timeout, enter a time limit for contacting the connected DNS recursors. This includes dialing, writing, and reading from the DNS recursor. If any of these actions exceeds the time limit you set, the action fails.
Note: This time limit must include one of the Go parse duration time units. For example, entering
5s sets the timeout limit to five seconds. For more information about supported time units, see func ParseDuration in the Go Programming Language documentation.
To configure BOSH Director logging:
Select Syslog in BOSH Director.
(Optional) To send BOSH Director system logs to a remote server, select Yes.
In the Address field, enter the IP address or DNS name for the remote server.
In the Port field, enter the port number that the remote server listens on.
In the Transport Protocol dropdown menu, select TCP or UDP. This selection determines which transport protocol is used to send the logs to the remote server.
(Optional) Select the Enable TLS check box to send encrypted logs to remote server with TLS. After you select the check box, perform the following steps:
Note: For an optimal security configuration, enable TLS encryption when you are forwarding logs. Logs can contain sensitive information, such as cloud provider credentials.
To configure BOSH Director resources:
Select Resource Config in BOSH Director.
Adjust any values as necessary for your deployment. Under the Instances, Persistent Disk Type, and VM Type fields, choose Automatic from the drop-down menu to allocate the recommended resources for the job. If the Persistent Disk Type field reads None, the job does not require persistent disk space.
Note: Ops Manager requires a Director VM with at least 8 GB memory.
Note: If you set a field to Automatic and the recommended resource allocation changes in a future version, Ops Manager automatically uses the updated recommended allocation.
Use the Ops Manager API to add custom properties to your VMs such as associated security groups and load balancers.
For more information, see Managing Custom VM Extensions.
To deploy BOSH:
Go to the Ops Manager Installation Dashboard.
Click Review Pending Changes.
Click Apply Changes.
Confirm changes applied successfully.
Check BOSH VM. Log in to vCenter and check for the
p-bosh VM deployment in the Tanzu Kubernetes Grid Integrated Edition Management resource pool.
After successfully deploying BOSH, ensure that both the Management AZ and the Compute AZs appear in the Tanzu Kubernetes Grid Integrated Edition tile Plans.
To ensure that the Management AZ and the Compute AZs are included in the
NET-MGMT-TKGI network you defined above:
Return to the BOSH tile and click Create Networks.
Edit the network (
NET-MGMT-TKGI) and each COMPUTE AZ.
Review pending changes, and click Apply Changes to redeploy BOSH.
