11 oc set route-backends [OPTIONS]
12
16 Set and adjust route backends
17 Routes may have one or more optional backend services with weights con‐
20 trolling how much traffic flows to each service. Traffic is assigned
21 proportional to the combined weights of each backend. A weight of zero
22 means that the backend will receive no traffic. If all weights are zero
23 the route will not send traffic to any backends.
24 When setting backends, the first backend is the primary and the other
27 backends are considered alternates. For example:
28 $ oc set route-backends web prod=99 canary=1
31 will set the primary backend to service "prod" with a weight of 99 and
34 the first alternate backend to service "canary" with a weight of 1.
35 This means 99% of traffic will be sent to the service "prod".
36 The --adjust flag allows you to alter the weight of an individual ser‐
39 vice relative to itself or to the primary backend. Specifying a per‐
40 centage will adjust the backend relative to either the primary or the
41 first alternate (if you specify the primary). If there are other back‐
42 ends their weights will be kept proportional to the changed.
43 Not all routers may support multiple or weighted backends.
46
50 --adjust=false

52 the primary backend is selected and there is more than one alternate an
53 error will be returned.

68 If true, only print the object that would be sent, without sending
