Register Tanzu Mission Control Self-Managed with Supervisor

To integrate Tanzu Mission Control Self-Managed with Supervisor, create a custom resource definition with that references the TMC Agent. Supervisor includes a Kubernetes namespace for TMC where the agent is installed.

Complete the following procedure.

Install Tanzu Mission Control Self-Managed as described in the documentation. See Installing and Running VMware Tanzu Mission Control Self-Managed.
Using a web browser, access the Tanzu Mission Control Self-Managed local deployment.
Export the root CA certificate for the Tanzu Mission Control Self-Managed installation.
- If you are using a well-known CA, click the lock icon to the left of the address bar in the browser and view the certificate. If you are using a private CA, click the not secure button and view the certificate.
- On the certificate dialog pop-up, select the Details tab and then the Export button to download a copy of the CA cert.
- Open the ca cert file with the text editor of your choice to access the CA cert content

Using the vSphere Plugin for kubectl, authenticate with Supervisor.

kubectl vsphere login --server=IP-ADDRESS --vsphere-username USERNAME

Run the following commend to list the available Kubectl contexts.
```
kubectl config get-contexts
```
Switch context to the target vSphere Namespace where the TKG cluster running Tanzu Mission Control Self-Managed is provisioned.
```
kubectl config use-context VSPHERE-NAMESPACE
```
Run the following command to list the Kubernetes namespaces.
```
kubectl get ns
```
The Kubernetes namespace on Supervisor for TMC is named svc-tmc-cXXXX (where XXXX is a number). For example, svc-tmc-c1208. Verify that this Kubernetes namespace exists and is active.
Use a text editor to create the custom resource definition named agentconfig.yaml. This file includes the TMC namespace, the hostname of your TMC Self-Managed deployment, and the CA cert contents.
- Enter the name of the Kubernetes Namespace for TMC in the namespace field.
- Enter the CA certificates in the caCerts fields.
- Enter the TMC host name in the allowedHostNames field.
