Which is a prerequisite for cert-manager installation?

A prerequisite for cert-manager installation is to obtain the admin credentials of the target workload cluster. Cert-manager is a tool that automates the management and issuance of TLS certificates within Kubernetes clusters3. To install cert-manager, users need to have access to the cluster where they want to deploy it, and have the necessary permissions to create resources such as namespaces, custom resource definitions, deployments, services, and secrets3. Users can obtain the admin credentials of the target workload cluster by using the tanzu cluster kubeconfig get command with the --admin option4. This command generates a kubeconfig file that contains the admin credentials for the cluster, which can be used to authenticate with the cluster and perform cert-manager installation4.
