User cluster configuration file 1.16

This page describes the fields in the Google Distributed Cloud user cluster configuration file.

Generating a template for your configuration file

If you used gkeadm to create your admin workstation, then gkeadm generated a template for your user cluster configuration file. And gkeadm filled in some of the fields for you.

If you did not use gkeadm to create your admin workstation, you can use gkectl to generate a template for your user cluster configuration file.

To generate a template for your user cluster configuration file:

gkectl create-config cluster --config=OUTPUT_FILENAME --gke-on-prem-version=VERSION

Replace the following:

OUTPUT_FILENAME: a path of your choice for the generated template. If you omit this flag, gkectl names the file user-cluster.yaml and puts it in the current directory.

VERSION: the desired version number. For example: gkectl create-config cluster --gke-on-prem-version=1.10.0-gke.8.

Template

Required fields and default values

If a field is marked as Required, then the completed configuration file must have a value filled in for the field.

Some fields are conditionally required. For example, loadBalancer.metalLB.addressPools is required if loadBalancer.kind is equal to MetalLB.

If a Default value is given for a field, then the cluster will use that value if you don't enter anything for the field. You can override a default value by entering a value.

If a field is not marked as Required and no Default value is given, then the field is optional. You can fill it in if it is relevant for you, but you don't have to fill it in.

Filling in your configuration file

In your configuration file, enter field values as described in the following sections.

name

Required
String

A name of your choice for your user cluster. The name must:

  • contain at most 40 characters
  • contain only lowercase alphanumeric characters or a hyphen (-)
  • start with an alphabetic character
  • end with an alphanumeric character

Example:

name: "my-user-cluster"

gkeOnPremVersion

Required
Mutable
String

The Google Distributed Cloud version for your user cluster.

Example:

gkeOnPremVersion: "1.14.0-gke.1"

enableControlplaneV2

Immutable
Boolean
Prepopulated: true
Default: true

To enable Controlplane V2, set enableControlplaneV2 to true or remove the setting from your user cluster configuration file. Otherwise, set it to false. With Controlplane V2, the control plane for a user cluster runs on one or more nodes in the user cluster itself. When Controlplane V2 isn't enabled, the user cluster control plane runs in the admin cluster.

We recommend that you enable Controlplane V2.

Example:

enableControlplaneV2: true

vCenter

This section holds information about your vSphere environment and your connection to vCenter Server.

If you want a field in this section to be the same as what you specified for your admin cluster, remove the field or leave it commented out.

If you want a field to be different from what you specified for your admin cluster, fill it in here. Any fields that you fill in here in the vCenter section override the corresponding fields in your admin cluster configuration file.

vCenter.address

Optional
Immutable
String
Default: Inherit from the admin cluster

The IP address or the hostname of the instance of vCenter Server that you want to use for this user cluster.

For more information, see Finding your vCenter server address.

If you specify a value that is different from the instance of vCenter Server used by the admin cluster, then Controlplane V2 must be enabled, and you must provide values for network.vCenter.networkName and all the required fields in the section vCenter.

Examples:

vCenter:

If your data center is in the root folder, the value is the name of the data center.

Example:

vCenter:
  datacenter: "my-uc-data-center"

Otherwise, the value is a relative path that includes one or more folders along with the name of the data center.

Example:

vCenter:
  datacenter: "data-centers/data-center-2"

network

This section holds information about your user cluster network.

network.hostConfig

This section holds information about NTP servers, DNS servers, and DNS search domains used by the VMs that are your cluster nodes. If you are using the Seesaw load balancer, this information also applies to your Seesaw VMs.

This section is required if one or more of the following are true:

  • network.ipMode.type is set to static
  • enableControlplaneV2 is set to true or allowed to default to true.
  • loadBalancer.kind is set to "Seesaw"

network.hostConfig.dnsServers

Required
Immutable
Array of strings.
The maximum number of elements in the array is three.

The addresses of DNS servers for the VMs.

Example:

network:
  hostConfig:
    dnsServers:
    - "172.16.255.1"
    - "172.16.255.2"

network.hostConfig.ntpServers

Required
Immutable
Array of strings

The addresses of time servers for the VMs to use.

Example:

network:
  hostConfig:
    ntpServers:
    - "216.239.35.0"

network.hostConfig.searchDomainsForDNS

Optional
Immutable
Array of strings

DNS search domains for the hosts to use. These domains are used as part of a domain search list.

Example:

network:
  hostConfig:
    searchDomainsForDNS:
    - "my.local.com"

network.ipMode.type

Required
Immutable
String
Prepopulated: "dhcp"
Default: "dhcp"

If you want your cluster nodes to get their IP address from a DHCP server, set this to "dhcp". If you want your cluster nodes to have static IP addresses chosen from a list that you provide, set this to "static".

Example:

network:
  ipMode:
    type: "static"

network.ipMode.ipBlockFilePath

Required if network.ipMode.type = static
Immutable
String

The path of the IP block file for your cluster.

Example:

network:
  ipMode:
    ipBlockFilePath: "/my-config-folder/user-cluster-ipblock.yaml"

network.serviceCIDR

Required
Immutable
String
Prepopulated: "10.96.0.0/20"

A range of IP addresses, in CIDR format, to be used for Services in your cluster. Must be at least a /24 range.

Example:

network:
  serviceCIDR: "10.96.0.0/20"

network.podCIDR

Required
Immutable
String
Prepopulated: "192.168.0.0/16"
Default: "192.168.0.0/16"

A range of IP addresses, in CIDR format, to be used for Pods in your cluster. Must be at least a /18 range.

Example:

network:
  podCIDR: "192.168.0.0/16"

The Service range must not overlap with the Pod range.

The Service and Pod ranges must not overlap with any address outside the cluster that you want to reach from inside the cluster.

For example, suppose your Service range is 10.96.232.0/24, and your Pod range is 192.168.0.0/16. Any traffic sent from a Pod to an address in either of those ranges will be treated as in-cluster and will not reach any destination outside the cluster.

In particular, the Service and Pod ranges must not overlap with:

  • IP addresses of nodes in any cluster

  • IP addresses used by load balancer machines

  • VIPs used by control-plane nodes and load balancers

  • IP address of vCenter servers, DNS servers, and NTP servers

We recommend that your Service and Pod ranges be in the RFC 1918 address space.

Here is one reason for the recommendation to use RFC 1918 addresses. Suppose your Pod or Service range contains external IP addresses. Any traffic sent from a Pod to one of those external addresses will be treated as in-cluster traffic and will not reach the external destination.

network.vCenter.networkName

Required if vCenter.address is different from the vCenter address you are are using for the admin cluster.
Immutable
String

The name of the vSphere network for your user cluster nodes.

Slash (/) %2f
Backslash (\) %5c
Percent sign (%) %25

If the network name is not unique in your data center, you can specify a full path.

Example:

network:
  vCenter:
    networkName: "/my-uc-datacenter/network/my-network"

loadBalancer.metalLB.addressPools[i].avoidBuggyIPs

Optional
Relevant if loadBalancer.kind = MetalLB
Mutable
Boolean
Prepopulated: false
Default: false

If you set this to true, the MetalLB controller will not assign IP addresses ending in .0 or .255 to Services. This avoids the problem of buggy consumer devices mistakenly dropping traffic sent to those special IP addresses.

Example:

loadBalancer:
  metalLB:
    addressPools:
    - name: "my-address-pool-1"
      - "192.0.2.0/26"
      - "192.0.2.64-192.0.2.72"
      avoidBuggyIPs: true
loadBalancer.metalLB.addressPools[i].manualAssign

Optional
Relevant if loadBalancer.kind = MetalLB
Mutable
Boolean
Prepopulated: false
Default: false

If you do not want the MetalLB controller to automatically assign IP addresses from this pool to Services, set this to true. Then a developer can create a Service of type LoadBalancer and manually specify one of the addresses from the pool.

Otherwise, set this to false.

Example:

loadBalancer:
  metalLB:
    addressPools:
    - name: "my-address-pool-1"
      manualAssign: true

Optional
Immutable
String
Possible values: "snat", "dsr"
Prepopulated: "snat"
Default: "snat"

The load balancing mode for a cluster that has Dataplane V2 enabled.

With source network address translation (SNAT) mode, a packet is SNAT-translated when it is forwarded from a load balancer node to a backend Pod. The Pod cannot see the original source IP address, and the return packet must pass through the load balancer node.

With direct server return (DSR) mode, a packet retains its original source IP address when it is forwarded from a load balancer node to a backend Pod. The Pod can see the original source IP address, and the return packet goes directly to the client without passing through the load balancer node.

Example:

dataplaneV2:
  lbMode: "dsr"
