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.
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
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 |
||
vsphere_public_network | FALSE | string | Blank | Name of the network the VMs are joined to |
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"
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.
