--- title: Using Tanzu Build Service Without Projects --- # Using Tanzu Build Service Without Projects Tanzu Build Service projects are a resource that simplifies kubernetes namespaces and RBAC to provide multitenancy for images, secrets, and builders. Projects are optional if users don't need to multitentancy or if they prefer to manage multitenacy via alternative mechanisms. ### Using the `pb` cli The pb cli can work with existing namespaces by targeting them as projects. 1. Get kubeconfig access to the Kubernetes cluster that has the Build Service installated. 1. Use the pb cli to target the namespace you want to create build service resources in. ``` pb project target NAMESPACE-NAME ``` <p class='note'><strong>Note:</strong> By default, the `pb` cli will use the `default` namespace if no namespace has been targeted.</p>
