Gardener Extension for SUSE CHost
This controller operates on the OperatingSystemConfig resource in the extensions.gardener.cloud/v1alpha1 API group. It manages those objects that are requesting SUSE Container Host configuration and supports both types (.spec.type=suse-chost and .spec.type=suse-jeos):
---
apiVersion: extensions.gardener.cloud/v1alpha1
kind: OperatingSystemConfig
metadata:
name: pool-01-original
namespace: default
spec:
type: suse-chost
units:
...
files:
...
Please find a concrete example in the example folder.
It is also capable of supporting the vSMP MemoryOne operating system with the memoryone-chost type. Please find more information here.
After reconciliation the resulting data will be stored in a secret within the same namespace (as the config itself might contain confidential data). The name of the secret will be written into the resource's .status field:
...
status:
...
cloudConfig:
secretRef:
name: osc-result-pool-01-original
namespace: default
command: /usr/bin/env bash <path>
units:
- docker-monitor.service
- kubelet-monitor.service
- kubelet.service
The secret has one data key cloud_config that stores the generation.
An example for a ControllerRegistration resource that can be used to register this controller to Gardener can be found here.
This controller is implemented using the oscommon library for operating system configuration controllers.
Please find more information regarding the extensibility concepts and a detailed proposal here.
How to start using or developing this extension controller locally
You can run the controller locally on your machine by executing make start. Please make sure to have the kubeconfig to the cluster you want to connect to ready in the ./dev/kubeconfig file.
Static code checks and tests can be executed by running make verify. We are using Go modules for Golang package dependency management and Ginkgo/Gomega for testing.
