The MicroK8s cloud and Juju

List of supported clouds > MicroK8s

This document describes details specific to using your existing MicroK8s cloud with Juju.

See more: MicroK8s

When using the MicroK8s cloud with Juju, it is important to keep in mind that it is a (1) Kubernetes cloud and (2) not some other cloud.

See more: Cloud differences in Juju

As the differences related to (1) are already documented generically in our Tutorial, How-to guides, and Reference docs, here we record just those that follow from (2).
