Authorizations

Authorization

header

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json
credential_id
string<uuid4>
required
name
string
required
ssh_key_credential_id
string<uuid4>
required
zone
string
required
bastion_allowed_ips
string[]

IPv4 addresses or CIDRs allowed to reach the bastion's SSH port. The platform's own egress addresses are always allowed in addition, so the platform can never be locked out. Omit (or send an empty list) to keep the bastion reachable from anywhere (key-only SSH, rate-limited). IPv6 and 0.0.0.0/0 entries are refused; at most 64 entries.

Maximum array length: 64
bastion_plan
string
default:1xCPU-1GB
cni
enum<string>

Container network. Omitted resolves to cilium on kubeadm (the default distribution) and flannel on k3s.

Available options:
flannel,
calico,
cilium
control_plane_count
integer
default:1
control_plane_plan
string
default:2xCPU-4GB
criticality
enum<string> | null
Available options:
production,
staging,
development,
disposable
description
string | null
distribution
string
default:kubeadm
environment

Required string length: 1 - 50
etcd_node_count
integer
default:3
etcd_plan
string
default:2xCPU-4GB
etcd_topology
string
default:stacked
external_cloud_provider
boolean
default:true
gateway_plan
string
default:standard

UpCloud NAT gateway plan every node's outbound internet runs through, from GET /api/v1/clusters/upcloud/gateway-plans. Omitted is 'standard', the cheapest plan on two servers: a one-server plan ('development', 'essentials') loses all cluster egress while UpCloud rebuilds it. An unlisted plan answers 400.

gitops_branch
string
default:master
gitops_credential_name
string | null
gitops_repository
string | null
gitops_provider
enum<string>
default:github

GitOps provider of the repository the cluster is bootstrapped onto. Omitted is github, where gitops_repository is owner/name. bitbucket_cloud names the repository by gitops_workspace and gitops_repo_slug (or gitops_repository as workspace/repo_slug) and binds it as a Bitbucket Cloud repository.

Available options:
github,
bitbucket_cloud
gitops_workspace
string | null

Bitbucket Cloud workspace of the GitOps repository. Only with gitops_provider bitbucket_cloud; provided together with gitops_repo_slug.

gitops_repo_slug
string | null

Bitbucket Cloud repository slug of the GitOps repository. Only with gitops_provider bitbucket_cloud; provided together with gitops_workspace.

include_networking
boolean
default:true
gateway_api
boolean
default:false

Install the Kubernetes Gateway API beside Traefik's Ingress: the Gateway API standard CRDs, Traefik's Gateway provider with the traefik GatewayClass and a shared traefik-gateway Gateway in the traefik namespace (a plain HTTP listener that accepts routes from every namespace), cert-manager's Gateway support, and external-dns publishing of HTTPRoute hostnames. Ingress keeps working; one Traefik serves both. Requires include_networking.

kubernetes_version
string | null
k3s_disabled_components
enum<string>[] | null

k3s packaged components to keep disabled (k3s --disable), for example ["traefik"] on a cluster that brings its own ingress. k3s distribution only: the list is rendered into the server config at install and re-asserted by the maintenance pass, so the entries stay off across restarts.

Available options:
coredns,
servicelb,
traefik,
local-storage,
metrics-server,
runtimes
load_balancer_plan
string | null

UpCloud plan of the ingress load balancer (see GET /api/v1/clusters/upcloud/load-balancer-plans). Omitted, it is production-small (two nodes) for a cluster whose criticality is production and development (one node) otherwise. Only meaningful with include_networking.

network_mode
enum<string>

Derived when omitted: wireguard_mesh for a multi-zone pool, private_network otherwise. Set wireguard_mesh on a single-zone cluster to make it mesh-capable so zones can be added later; a mesh cannot be retrofitted.

Available options:
private_network,
wireguard_mesh
network_ip_range
string | null
node_groups
CreateUpcloudNodeGroupRequest · object[] | null
worker_count
integer
default:1
worker_plan
string
default:2xCPU-4GB
zones
string[]

Zone pool for a multi-zone cluster. Must contain zone (the primary zone: bastion, first control plane and default network). Each additional zone gets its own SDN router, private network and NAT gateway, and the nodes are joined by a platform-managed WireGuard mesh. More than one zone needs at least three zones and three control planes. Omitted keeps the cluster in zone only.
