Deploy App Delivery Network

This example creates a sample namespace called tutorial-hipster namespace.

• Select the Administration workspace.
• Select Personal Management > My namespaces.

Figure: Navigate to Manage Namespaces

• Click Add namespace and enter a name for your namespace. Click Save changes to complete creating the namespace.

Figure: Create Namespace

• Change to the Distributed Apps workspace.

• Click on the application namespace option on the namespace selector. Select the namespace created in previous step from the namespace dropdown list to change to that namespace.

• Select Applications in the configuration menu and Virtual K8s in the options pane.

  

  Figure: Navigate to vK8s Creation

• Click Add Virtual K8s and enter a name for your vK8s cluster.

Figure: Select Virtual Site for vK8s

• Click the Select vsite ref button and select ves-io-all-res. Click the Select Vsite Ref button at the bottom to apply the virtual site to the vK8s configuration.

• Click Save and Exit to start creating the vK8s clusters in all RE sites.

• Once the vK8s object is created, click ...> Kubeconfig for it and enter an expiration date to download its kubeconfig file.

To deploy the web application in a K8s cluster, the following are required:

• Kubeconfig of the K8s cluster. For this, use the vK8s kubeconfig downloaded in previous step.
• Manifest file of your web application. Download the sample this example uses and edit its fields as per your application.

Enter the following command to deploy the application:

kubectl --kubeconfig ves_adn_adn.yaml --namespace adn apply -f kubernetes-manifests.yaml

Note: You can download the kubectl application here: kubeclt.

This completes deployment of application across all RE sites.

• Select the Multi-Cloud App Connect workspace.
• Select the namespace created in step 1.1 where we previously deployed our application onto our vk8.
• Navigate to Manage in the left menu. Select Load Balancers > HTTP Load Balancers from the options. Click Add HTTP Load Balancer to start load balancer creation.

• Enter a name for the load balancer.
• Under Domains and LB Type in the List of Domains field, enter the domain(s) that will be matched to this load balancer.
• Select the Load Balancer Type. For this quick start, we will select HTTPS with Automatic Certificate.

• Scroll down to the Origins section and click Add Item to set up an origin pool.

• Use the Origin Pool pull-down menu to find and click the Create new origin pool button.

• Enter a name for the new origin pool.

• In the Origin Servers section, click Add Item.

  • In the Select Type of Origin Server field, select K8s Service Name of Origin Server on given Sites.
  • Enter a name in the Service Name field in the form <unique-name>.<namespace>. For the quick start example, we'll enter frontend.adn.
  • Set this as a Virtual Site in the Site or Virtual Site field.
  • Set the virtual site to the same site used when you created your virtual kubernetes cluster. In this example, we used ves-io-all-res.
  • For the Select Network on the site field, select vK8s Networks on Site.
  • Click Add Item to save the origin server.

• Click Add Item to add this pool to the HTTP load balancer.
• Click Save and Exit to complete the HTTP load balancer.
• Press the Refresh button to update the TLS info column in the load balancer table. After a few minutes, the TLS info will be certified, and we'll be able to access our application through the domain we specified.

• Select the Web App & API Protection workspace.

• Select the namespace used to create the HTTP load balancer previously.

• Navigate to Manage > Load Balancers > HTTP Load Balancers.

• Click ...>Manage Configuration for your load balancer, and then click Edit Configuration in the top right to edit the load balancer's configuration.

• Scroll down or click on Security Configuration in the left menu to go to the security configuration section.
