This document shows how to create a user cluster for GKE on VMware.
The instructions here are part of a quickstart. For full instructions on how to create a user cluster, see Creating a user cluster.
Before you begin
Get an SSH connection to your admin workstation
Your component access service account is activated on your admin workstation.
Do all the remaining steps in this topic on your admin workstation in the home directory.
Specify static IPs for your user cluster
To specify the static IP addresses that you want to use for your user cluster,
IP block file
user-cluster-ipblock.yaml. For this exercise, you need to specify three IP
addresses to be used by the user cluster.
Here is an example of an IP block file with three hosts:
blocks: - netmask: 255.255.252.0 gateway: 172.16.23.254 ips: - ip: 172.16.20.15 hostname: user-host1 - ip: 172.16.20.16 hostname: user-host2 - ip: 172.16.20.17 hostname: user-host3
ips field is an array of IP addresses and hostnames. These are the IP
addresses and hostnames that GKE on VMware will assign to
your user cluster nodes.
In the IP block file, you also specify the addresses of the DNS servers, time servers, and default gateway that the user cluster nodes will use.
User cluster configuration file
gkeadm created your admin workstation, it generated a configuration file
user-cluster.yaml. This configuration file is for creating your user
Fill in your user cluster configuration file
Several fields in your user cluster configuration file are already filled in with default values, generated values, or values that you provided when you created your admin workstation. You can leave those fields unchanged.
Fill in the following fields. For instructions on how to fill in the fields, see User cluster configuration file.
name: "Fill in" network: hostConfig: dnsServers: - "Fill in" ntpServers: - "Fill in" searchDomainsForDNS: - "Fill in (optional)" ipMode: type: Fill in. Set to "static". ipBlockFilePath: "Fill in" loadBalancer: vips: controlPlaneVIP: "Fill in" ingressVIP: "Fill in" seesaw: ipBlockFilePath: "Fill in" vrid: Fill in masterIP: "Fill in"
Validate the user cluster configuration file
Verify that the your user cluster configuration file is valid and can be used for cluster creation:
gkectl check-config --kubeconfig kubeconfig --config user-cluster.yaml
Create a load balancer for your user cluster
Create and configure the VM for your Seesaw load balancer:
gkectl create loadbalancer --kubeconfig kubeconfig --config user-cluster.yaml
Create the user cluster
Create the user cluster:
gkectl create cluster --kubeconfig kubeconfig --config user-cluster.yaml
Locate the user cluster kubeconfig file
gkectl create cluster command creates a kubeconfig file named
USER_CLUSTER_NAME-kubeconfig in the current directory. You will need this
kubeconfig file later to interact with your user cluster.
Verify that your user cluster is running
Verify that your user cluster is running:
kubectl get nodes --kubeconfig USER_CLUSTER_KUBECONFIG
Replace USER_CLUSTER_KUBECONFIG with the path of your kubeconfig file.
The output shows the user cluster nodes. For example:
my-user-cluster-node-pool-69-d46d77885-7b7tx Ready ... my-user-cluster-node-pool-69-d46d77885-lsvzk Ready ... my-user-cluster-node-pool-69-d46d77885-sswjk Ready ...
