<p>&nbsp;</p>
<h3><strong>Technical Requirements for API Portal</strong></h3>
<p>To get started with API management Portal for VMware Tanzu, organizations need to meet specific technical prerequisites:</p>
<h4><strong>1. Kubernetes Cluster</strong></h4>
<p>A running Kubernetes cluster is essential for deploying the API Portal. Organizations can select any suitable Kubernetes distribution.</p>
<h4><strong>2. Tanzu Application Platform (TAP)</strong></h4>
<p>As a component of TAP, API Portal must be installed on the Kubernetes cluster prior to deployment.</p>
<h4><strong>3. Container Registry</strong></h4>
<p>An account on a container registry supporting TLS is necessary for storing container images.</p>
<h4><strong>4. OIDC Provider for SSO</strong></h4>
<p>Organizations aiming to implement Single Sign-On need an OpenID Connect (OIDC) provider, such as Okta.</p>
<h4><strong>5. Helm CLI</strong></h4>
<p>The Helm CLI is required for managing Kubernetes applications and deploying the API Portal.</p>
<p>&nbsp;</p>
<h3><strong>Getting Started with API Portal for VMware Tanzu</strong></h3>
<h4><strong>Step 1: Setting Up the Kubernetes Cluster</strong></h4>
<p>Before deploying the API Portal, ensure you have a functional Kubernetes cluster. This can be established using various cloud service providers or local setups like Minikube or Docker Desktop.</p>
<h4><strong>Step 2: Installing Tanzu Application Platform</strong></h4>
<p>Follow the Tanzu documentation to install TAP on your Kubernetes cluster. This involves configuring the necessary values and deploying the TAP packages effectively.</p>
<h4><strong>Step 3: Deploying API Portal</strong></h4>
<p>After TAP installation, deploy API Portal using the following Helm command:</p>
<p>&#8220;`bash<br />
helm install api-portal tanzu/api-portal &#8211;namespace tap-install<br />
&#8220;`</p>
<p>This command deploys the API Portal in the specified namespace.</p>
<h4><strong>Step 4: Configuring API Portal</strong></h4>
<p>Post-deployment, configure the API Portal to connect with your API sources. Specify the source URLs for OpenAPI documentation through a configuration file.</p>
<h4><strong>Step 5: Accessing the API Portal</strong></h4>
<p>Once configured, access the API management Portal via the Tanzu Application Platform GUI. Here you can manage APIs, view documentation, and monitor usage.</p>
<p>&nbsp;</p>
<h3><strong>Real-World Use Case: Animal Rescue Application</strong></h3>
<p>To illustrate the capabilities of API  management Portal for VMware Tanzu, let’s explore a real-world use case. This involves an API-driven application called Animal Rescue. This application simulates an animal adoption site and integrates with Okta for Single Sign-On.</p>
<h4><strong>Step 1: Cloning the Application Repository</strong></h4>
<p>Start by cloning the Git repository containing the Animal Rescue application:</p>
<p>&#8220;`bash<br />
git clone https://github.com/PacktPublishing/DevSecOps-in-Practice-with-VMware-Tanzu<br />
cd DevSecOps-in-Practice-with-VMware-Tanzu/chapter-05/animal-rescue/<br />
&#8220;`</p>
<h4><strong>Step 2: Configuring Okta for SSO</strong></h4>
<p>Set up an Okta developer account. Configure it to provide SSO for the Animal Rescue application by creating an application in Okta and specifying the redirect URIs.</p>
<h4><strong>Step 3: Deploying the Application</strong></h4>
<p>Deploy the Animal Rescue application to your Kubernetes cluster. Create the necessary Spring Cloud Gateway artifacts to interact with the application.</p>
<h4><strong>Step 4: Connecting API Portal with Spring Cloud Gateway</strong></h4>
