Gardener machine controller manager provider for vSphere (out-of-tree)

machine-controller-manager-provider-vsphere

Out of tree (gRPC based) implementation for vSphere as a new provider.

About

This repository implements a CMI plugin for managing machines (VMs) on vSphere. It implements the services defined at machine-spec.

Details about the ProviderSpec and the Secrets can be found in provider_spec.go

Prerequisites

• vSphere installation, user with permissions to create/delete VMs in the specified data center
• A vSphere network with an DHCP server. For Gardener, the network is created by the vsphere infrastructure controller, which needs VMware NSX-T to setup the software-defined network, SNAT and DHCP.
• Suitable VM templates must already be deployed on vSphere. The provider uses the guestId to identify the correct way to initiate a cloud-init. Supported OS are
  • CoreOS images using igniton for cloud-init (see https://stable.release.core-os.net/amd64-usr for images) In this case make sure, that the guestId is overwritten with coreos64Guest in the ProviderSpec.
  • Other Linux cloud images with a cloud-init VApp (e.g. Ubuntu at https://cloud-images.ubuntu.com/releases) can be used if they meet the requirements like Docker, SystemD, ... (see Gardener contract for OperationSystemConfig for more details)

Supports vSphere versions

Currently this provider has only be tested with vSphere 6.7 (Update 3)
