As Glasskube is still in technical preview a manual bootstrap is needed.
Automatic detection and bootstrapping will be implemented in a future version.

In order to install packages in a Kubernetes cluster using Glasskube, it is necessary to install the required server components. Conveniently, for most users this can be achieved by running glasskube bootstrap in a terminal.

The bootstrap command installs the Package Operator and it's associated Custom Resource Definitions (CRDs). By default, the Package Operator is installed in an All-In-One (AIO) configuration. This configuration comes bundled with a subset of Flux. Glasskube is still compatible with any other GitOps solution, but Flux is a necessary requirement of the Package Operator.

If you already use Flux in your cluster or want to manage it yourself, first install Flux, and then Glasskube using a slim configuration by running glasskube bootstrap --type=slim.
