vSphere cloud provider

Kubespray can be deployed with vSphere as Cloud provider. This feature supports

• Volumes
• Persistent Volumes
• Storage Classes and provisioning of volumes.
• vSphere Storage Policy Based Management for Containers orchestrated by Kubernetes.

Prerequisites

You need at first to configure you vSphere environement by following the official documentation.

After this step you should have:

• UUID activated for each VM where Kubernetes will be deployed
• A vSphere account with required privileges

Kubespray configuration

Fist you must define the cloud provider in inventory/group_vars/all.yml and set it to vsphere.

cloud_provider: vsphere

Then, in the same file, you need to declare your vCenter credential following the description bellow.

Variable	Required	Type	Choices	Default	Comment
vsphere_vcenter_ip	TRUE	string			IP/URL of the vCenter
vsphere_vcenter_port	TRUE	integer			Port of the vCenter API. Commonly 443
vsphere_insecure	TRUE	integer	1, 0		set to 1 if the host above uses a self-signed cert
vsphere_user	TRUE	string			User name for vCenter with required privileges
vsphere_password	TRUE	string			Password for vCenter
vsphere_datacenter	TRUE	string			Datacenter name to use
vsphere_datastore	TRUE	string			Datastore name to use
vsphere_working_dir	TRUE	string			Working directory from the view "VMs and template" in the vCenter where VM are placed
vsphere_scsi_controller_type	TRUE	string	buslogic, pvscsi, parallel	pvscsi	SCSI controller name. Commonly "pvscsi".
vsphere_vm_uuid	FALSE	string			VM Instance UUID of virtual machine that host K8s master. Can be retrieved from instanceUuid property in VmConfigInfo, or as vc.uuid in VMX file or in /sys/class/dmi/id/product_serial (Optional, only used for Kubernetes <= 1.9.2)
vsphere_public_network	FALSE	string		Blank	Name of the network the VMs are joined to
vsphere_resource_pool	FALSE	string		Blank	Name of the Resource pool where the VMs are located (Optional, only used for Kubernetes >= 1.9.2)

Example configuration

vsphere_vcenter_ip: "myvcenter.domain.com"
vsphere_vcenter_port: 443
vsphere_insecure: 1
vsphere_user: "k8s@vsphere.local"
vsphere_password: "K8s_admin"
vsphere_datacenter: "DATACENTER_name"
vsphere_datastore: "DATASTORE_name"
vsphere_working_dir: "Docker_hosts"
vsphere_scsi_controller_type: "pvscsi"
vsphere_resource_pool: "K8s-Pool"

Deployment

Once the configuration is set, you can execute the playbook again to apply the new configuration

cd kubespray
ansible-playbook -i inventory/inventory.cfg -b -v cluster.yml

You'll find some usefull examples here to test your configuration.
