Kubernetes clouds and Juju¶
In Juju, all Kubernetes clouds behave fundamentally the same.
Kubernetes in Juju¶
Juju supports both traditional machine clouds as well as Kubernetes clouds. If you are familiar with Kubernetes, the following is a mapping between Kubernetes and Juju concepts:
Notes on juju add-k8s¶
On Kubernetes clouds, both the cloud definition and the cloud credentials are added through juju add-k8s, which reads from your kubeconfig file.
