Addons

The Add-ons are Helm workloads that are generally considered useful to a wide audience.

Desktop Kubernetes supports Add-ons as follows:

1. The config.yaml specifies an Add-On name.
2. That Add-On name has to exactly match a subdirectory under the scripts/addons directory.
3. The CLI loops through all enabled add-ons and simply runs a script named install in each such directory matching the name of the enabled Add-On.

Add-On install scripts

Each Add-On install script does the same things:

1. Downloads the Add-On tarball using a hard-coded version in the Add-On install script.
2. Helm-installs the Add-On.

Some Add-Ons are more complex because because the Add-On might require:

1. Templating Helm values
2. Manipulating the guest VMs. (E.g.: Calico requires copying a config file to each host and restarting NetworkManager)

For those you will see more logic in the Add-On install script. In general, the approach is for the main CLI dtk to know nothing about the Add-Ons except how to find the install script.

See the Components and Versions Section for a list of the Add-Ons and versions.
