SYNOPSIS

11       oc set route-backends [OPTIONS]

DESCRIPTION

16       Set and adjust route backends
17
18
19       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
25
26       When  setting  backends, the first backend is the primary and the other
27       backends are considered alternates. For example:
28
29
30       $ oc set route-backends web prod=99 canary=1
31
32
33       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
37
38       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
44
45       Not all routers may support multiple or weighted backends.
46

48

OPTIONS

50       --adjust=false
51           Adjust a single backend using an absolute or  relative  weight.  If
52       the primary backend is selected and there is more than one alternate an
53       error will be returned.
54
55
56       --all=false

66
67       --dry-run=false

103
104
