Tanzu Application Platform (TAP) Deployment Script

This script is focused on simplifying the deployment of Tanzu Application Platform

Current Release: TAP 1.5.1 Tested Platforms: GKE Source Laptop: MacOS

Step 1: Setup Cluster

I have been using GKE as detailed below but k8s services comprised as:

  • local (kind), TKG 2.1+, GKE, AKS, EKS cluster
  • Version support is 1.23, 1.24 and 1.25
  • Network policies enabled

Also ensure the cluster context is set to target cluster

1.1 Steps for test GKE cluster as below

  1. Manual install of cluster not autopilot
  2. I target regional for availability but find 4 nodes of config e2-standard-2 or the like provides enough resources (2vcpu, 8GB RAM, 100GB disk per node)
  3. Set version control to static, version 1.19, 1.20 or1.21
  4. disable auto upgrade
  5. Enable K8s Network Policy
  6. Ensure Load Balancer is enabled

Step 2: Set script variable values

Set your variables in the tap_config.sh file.

  1. If password files not used such as with the GCR service account key file, then add values directly into the variables and keep the file variables empty
  2. If a custom DNS domain is required for CNR then set the CUSTOM_DOMAIN variable. Leaving it empty will not set any value so will be knative default welcome.com
  3. Set deployment model variable *'DEPLOYMENT_MODEL as either 'local' or 'cluster' to ensure that network services are corectly using either NodePort or LoadBalancer
  4. Set a namespace target to be initially enabled for workloads

Step 3: Install Carvel tools

install Carvel cli tools https://github.com/vmware-tanzu/carvel-kapp/releases. Release v0.42.0 tested with this script)

Step 4. Install the Tanzu CLI

Install Tanzu CLI 0.5.0 from TAP source on Tanzu Network and follow the procedures to initialise the required plug-ins at at Tanzu CLI Install Instructions

Step 5. Install Packages required for TAP

Run script sh ./tap-install.sh

Step 6. Some post deployment thoughts

  • image policy set to warn not enforce

New Developer Target Namespace

You can add more namespaces ready for workloads by the following steps

  1. Create Namespace
  2. Set ImagePull secret with Tanzu CLI
  3. Apply the Developer security artefect dev-namespace-enable.yaml
  4. Edit the App Live view configuration file app-live-view-values and update package woth the command: tanzu package installed update app-live-view appliveview.tanzu.vmware.com app-live-view-values.yaml
