Rotate a Client VPN endpoint's WireGuard server key.

POST

/v1/projects/{projectId}/network/client-vpn-endpoints/{clientVpnEndpointId}/rotate-server-key

Code sample: Shell / cURL

curl --request POST \
  --url https://stratum.example.com/v1/projects/example/network/client-vpn-endpoints/example/rotate-server-key \
  --header 'Authorization: Bearer <token>'

• A Stratum cluster endpoint.

Regenerates the endpoint’s WireGuard server keypair — for remediating a suspected key compromise. The old private key is purged and a fresh keypair is provisioned; the reconciler re-homes the terminator onto the new key within a reconcile interval. This is intentionally disruptive: every enrolled client’s .conf pins the OLD server public key, so all clients must re-download their configuration (client-config) to reconnect. There is no zero-downtime overlap — a single terminator interface carries one server key. The endpoint must be available.

Responses

200

The endpoint; serverPublicKey will repopulate once the reconciler regenerates it.

Media typeapplication/json

A per-VPC WireGuard terminator for remote user access (AWS-Client-VPN-shaped). serverPublicKey is populated once the data-plane terminator is provisioned.

vpcId

clientCidrBlock

required

The address pool handed to connecting clients (IPv4 /16../22).

string

authMode

required

string

Allowed values: oidc certificate

splitTunnel

required

True routes only VPC/authorized CIDRs; false is a full tunnel.

boolean

dnsServers

Pushed resolvers; empty means the VPC.3 resolver default.

Array<string>

connectionLogging

required

Emit per-connection events to observability.

boolean

serverPublicKey

WireGuard server public key; empty until the terminator is provisioned.

string

floatingIpId

The floating IP DNAT’d to the terminator for public ingress; empty when none is bound.

string

/^fip-[a-z0-9-]+$/

publicEndpoint

The terminator’s reachable “:51820”; empty until a floating IP is associated.

string

subnetIds

Tenant subnets the endpoint has an interface in.

Array<string>

securityGroupIds

Security groups governing who may reach the endpoint. Empty when the endpoint uses the pre- shared-transit path, where ingress is all-or-nothing on the floating IP association.

Array<string>

nicIds

The Stratum-owned NICs backing this endpoint, one per subnet. These carry the security groups and their addresses are what the floating IP forwards to. Empty means the endpoint is on the shared-transit path and its security groups, if any, govern nothing.

Array<string>

state

required

string

Allowed values: creating available deleting deleted error

tags

AWS-shape resource tags. Freeform UTF-8 keys (1-128 bytes, no leading/trailing whitespace) mapped to freeform UTF-8 values (0-256 bytes). Max 50 tags per resource. Reserved prefixes (stratum.dev/, stratum.platform_health., stratum:, aws:) return 400 RESERVED_NAMESPACE on customer input. PATCH replaces the whole map..

Field errors, for codes that carry them: each problem at its field (see FieldError). Documented on the responses that set it, e.g. approveNodeJoin’s INVALID_INPUT and JOIN_APPROVAL_REFUSED. Absent otherwise.

Array<object>

One field’s problem, the stage-2 installer API’s shape. field is the field’s path, message what is wrong with it.

string

details

Structured facts about the refusal, for codes that carry them. The shape is fixed per code and documented on the response that answers it, e.g. IMAGE_POOL_MISMATCH (see ImagePoolMismatchDetails) and IMAGE_IN_USE. Absent for codes that carry none.
