-This block brings everything together and executes the build. It calls the `source.vsphere-iso.ubuntu-k8s` block defined above, and also ties in a few `file` and `shell` provisioners. `file` provisioners are used to copy files (like SSL CA certificates and SSH keys) into the VM, while the `shell` provisioners run commands and execute scripts. Those will be handy for the post-deployment configuration tasks, like updating and installing packages.

 The `-on-error=abort` option makes sure that the build will abort if any steps in the build fail, and `-force` tells Packer to delete any existing VMs/templates with the same name as the one I'm attempting to build.

+My brand new `k8s-u2004` template is ready for use! In the next post, I'll walk through the process of *manually* cloning this template to create my Kubernetes nodes, initializing the cluster, and installing the vSphere integrations. After that process is sorted out nicely, we'll take a look at how to use Terraform to do it all automagically. Stay tuned!
