TransportServer¶

The TransportServer resource exposes the non-HTTP traffic configuration for a virtual server address in BIG-IP.

apiVersion: "cis.f5.com/v1"
kind: TransportServer
metadata:
   name: transport-server
   labels:
     f5cr: "true"
spec:
  virtualServerAddress: "172.16.3.9"
  virtualServerPort: 8585
  mode: standard
  snat: auto
  pool:
    service: svc-3
    servicePort: 8181
    monitor:
      type: tcp
      interval: 10
      timeout: 10
  serviceAddress:
  - icmpEcho: "enable"
    arpEnabled: true
    routeAdvertisement: "all"
    spanningEnabled: true

Important

The TransportServer in this example only forwards the traffic. It is the user’s responsibility to implement secure non-http traffic.

UDP Transport Server¶

The value spec.type can be used to distinguish a TCP/UDP transport sever.

In the example below, transport server creates a UDP Virtual Server on BIG-IP that can be accessed at 172.16.3.10:8444.

apiVersion: "cis.f5.com/v1"
kind: TransportServer
metadata:
   name: transport-server
   labels:
   f5cr: "true"
spec:
   virtualServerAddress: "172.16.3.10"
   virtualServerPort: 8444
   mode: standard
   snat: auto
   type: udp
   pool:
   service: udp-svc
   servicePort: 4444
   monitor:
      type: udp
      interval: 10
      timeout: 31

Components¶

TransportServer Components¶

Parameter	Type	Required	Default	Description
pool	Pool	Required	N/A	BIG-IP Pool member.
virtualServerAddress	String	Optional	N/A	IP Address of BIG-IP Virtual Server. IP address can also be replaced by a reference to a Service_Address.
ipamLabel	String	Optional	N/A	IPAM label name for IP address management which is mapped to IP-range in IPAM controller deployment.
serviceAddress	List	Optional	N/A	Service address definition allows you to add a number of properties to your (virtual) server address.
virtualServerPort	String	Required	N/A	Port Address of BIG-IP Virtual Server.
virtualServerName	String	Optional	N/A	Custom name of BIG-IP Virtual Server.
type	String	Optional	tcp	L4 transport server type. Options are “tcp” or “udp”.
mode	String	Required	N/A	A Standard mode transport server processes connections using the full proxy architecture. A Performance mode transport server uses FastL4 packet-by-packet TCP behavior. You can use “standard” or “performance”.
snat	String	Optional	auto	Reference to SNAT pool on BIG-IP. The other allowed value is: `none`.
allowVlans	List of VLANs	Optional	Allow traffic from all VLANs	List of VLAN objects from which to allow traffic. Example:[“/Common/devtraffic”].

Pools Components¶

Parameter	Type	Required	Default	Description
service	String	Required	N/A	Service deployed in Kubernetes cluster.
servicePort	String	Required	N/A	Port to access service.
monitor	String	Optional	N/A	Health Monitor to check the health of Pool Members.

Monitor Components¶

Parameter	Type	Required	Default	Description
type	String	Required	N/A	TCP or UDP.
interval	Int	Required	5	Seconds between health queries.
timeout	Int	Optional	16	Seconds before query fails.
