# Configuring the admin workstation
# Admin workstation OVA
On the first deployment of the admin workstation, the playbooks will download the workstation OVA and store it in the <<output_directory>> (see the section Output files).
If you want to use a local copy of the OVA, set the variable gkeadm_ova_path to point to the downloaded file.
If defined and the value is valid, gkeadm will use this file. If empty or invalid, gkeadm will download the OVA into
the directory defined by the variable output_directory.
| Variable | File | Description |
|---|---|---|
gkeadm_ova_path | inventory/group_vars/all/all.yml | Location on the Ansible controller for OVA |
# General config
The following fields in the gke_admin_workstation structure provide general configuration for the admin workstation:
| Variable | File | Description |
|---|---|---|
gke_admin_workstation .name | inventory/group_vars/all/all.yml | The name to use for your admin workstation. For example, 'gke-adm-test' |
gke_admin_workstation .cpus | inventory/group_vars/all/all.yml | The number of virtual CPUs for your admin workstation. For example, '4' |
gke_admin_workstation .memoryMB | inventory/group_vars/all/all.yml | The number of megabytes of memory for your admin workstation. For example, '8192' |
gke_admin_workstation .diskGB | inventory/group_vars/all/all.yml | The number of gigabytes of virtual disk space for your admin workstation. Must be at least 50. For example, '100' |

gke_admin_workstation .ntpServer | inventory/group_vars/all/all.yml | The hostname or IP address of the Network Time Protocol server that your admin workstation should use. For example, 'http://16.100.211.43:8888' |
gke_admin_workstation .ssh_private_key | inventory/group_vars/all/all.yml | The name of the SSH keypair to be deployed to GKE Admin Workstation. For example, 'vsphere_workstation'. For more information, see the section Input files. |
# Networking config
The following fields in the gke_admin_workstation structure provide networking configuration for the admin workstation:
| Variable | File | Description |
|---|---|---|
gke_admin_workstation .ipAllocationMode | inventory/group_vars/all/all.yml | One of 'dhcp' or 'static'. If you choose 'static', you must set the following following variables. |
gke_admin_workstation .ip | inventory/group_vars/all/all.yml | An IP address of your choice for your admin workstation. For example, '192.168.1.10'. |
gke_admin_workstation .gateway | inventory/group_vars/all/all.yml | The IP address of the default gateway for the network that contains your admin workstation. For example, '192.168.1.1'. |
gke_admin_workstation .netmask | inventory/group_vars/all/all.yml | The netmask for the network that contains your admin workstation. For example, '255.255.255.0'. |
gke_admin_workstation .dns | inventory/group_vars/all/all.yml | An array of IP addresses for DNS servers that your admin workstation can use. For example, - "172.16.255.1" - "172.16.255.2" |
# Alternative vCenter
If you want to deploy your GKE Admin Workstation to a different vSphere infrastructure than that used for the admin and user clusters, then you must configure a second set of variables using the
gke_admin_workstation.alt_vcenter structure:
| Variable | File | Description |
|---|---|---|
gke_admin_workstation .alt_vcenter.enable | inventory/group_vars/all/all.yml | Choose if you want to deploy the admin workstation to different infrastructure. Defaults to false |
gke_admin_workstation .alt_vcenter.address | inventory/group_vars/all/all.yml | IP or hostname of the vCenter appliance. For example, vcentergen10.am2.cloudra.local |
gke_admin_workstation .alt_vcenter.username | inventory/group_vars/all/all.yml | Uses the value of the vault_vcenter_username variable from the vault |
gke_admin_workstation .alt_vcenter.password | inventory/group_vars/all/all.yml | Uses the value of the vault_vcenter_password variable from the vault |
gke_admin_workstation .alt_vcenter.datacenter | inventory/group_vars/all/all.yml | Name of the datacenter where the environment will be provisioned. For example, Datacenter |
gke_admin_workstation .alt_vcenter.datastore | inventory/group_vars/all/all.yml | The datastore for storing VMs. For example, ds1 |
gke_admin_workstation .alt_vcenter.cluster | inventory/group_vars/all/all.yml | Name of your SimpliVity Cluster as defined in vCenter. |
gke_admin_workstation .alt_vcenter.network | inventory/group_vars/all/all.yml | The name of the vSphere network where you want to create your admin workstation. |
gke_admin_workstation .alt_vcenter.resourcepool | inventory/group_vars/all/all.yml | If you are using a non-default resource pool, provide the name of your vSphere resource pool. For example, Anthos_1.4 |
gke_admin_workstation .alt_vcenter.cacert | inventory/group_vars/all/all.yml | When a client, like GKE on-prem, sends a request to your vCenter server, the server must prove its identity to the client by presenting a certificate or a certificate bundle. To verify the certificate or bundle, GKE on-prem must have the root certificate in the chain of trust. This field contains the name of the file, for example gke_admin_workstation.alt_vcenter.pem and the file must be present in directory defined by secrets_directory. |
