.SH NAME
.PP
oc set route\-backends \- Update the backends for a route


.SH SYNOPSIS
.PP
\fBoc set route\-backends\fP [OPTIONS]


.SH DESCRIPTION
.PP
Set and adjust route backends

.PP
Routes may have one or more optional backend services with weights controlling how much traffic flows to each service. Traffic is assigned proportional to the combined weights of each backend. A weight of zero means that the backend will receive no traffic. If all weights are zero the route will not send traffic to any backends.

.PP
When setting backends, the first backend is the primary and the other backends are considered alternates. For example:

.PP
$ oc set route\-backends web prod=99 canary=1

.PP
will set the primary backend to service "prod" with a weight of 99 and the first alternate backend to service "canary" with a weight of 1. This means 99% of traffic will be sent to the service "prod".

.PP
The \-\-adjust flag allows you to alter the weight of an individual service relative to itself or to the primary backend. Specifying a percentage will adjust the backend relative to either the primary or the first alternate (if you specify the primary). If there are other backends their weights will be kept proportional to the changed.

.PP
Not all routers may support multiple or weighted backends.


.SH OPTIONS
.PP
\fB\-\-adjust\fP=false
    Adjust a single backend using an absolute or relative weight. If the primary backend is selected and there is more than one alternate an error will be returned.

.PP
\fB\-\-all\fP=false
    If true, select all resources in the namespace of the specified resource types

.PP
\fB\-\-equal\fP=false
    If true, set the weight of all backends to 100.

.PP
\fB\-f\fP, \fB\-\-filename\fP=[]
    Filename, directory, or URL to file to use to edit the resource.

.PP
\fB\-\-no\-headers\fP=false
    When using the default or custom\-column output format, don't print headers.

.PP
\fB\-o\fP, \fB\-\-output\fP=""
    Output format. One of: json|yaml|wide|name|custom\-columns=...|custom\-columns\-file=...|go\-template=...|go\-template\-file=...|jsonpath=...|jsonpath\-file=... See custom columns [
\[la]http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns\[ra]], golang template [
\[la]http://golang.org/pkg/text/template/#pkg-overview\[ra]] and jsonpath template [
\[la]http://kubernetes.io/docs/user-guide/jsonpath\[ra]].

.PP
\fB\-\-output\-version\fP=""
    Output the formatted object with the given group version (for ex: 'extensions/v1beta1').

.PP
\fB\-l\fP, \fB\-\-selector\fP=""
    Selector (label query) to filter on

.PP
\fB\-a\fP, \fB\-\-show\-all\fP=true
    When printing, show all resources (false means hide terminated pods.)

.PP
\fB\-\-show\-labels\fP=false
    When printing, show all labels as the last column (default hide labels column)

.PP
\fB\-\-sort\-by\fP=""
    If non\-empty, sort list types using this field specification.  The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.

.PP
\fB\-\-template\fP=""
    Template string or path to template file to use when \-o=go\-template, \-o=go\-template\-file. The template format is golang templates [
\[la]http://golang.org/pkg/text/template/#pkg-overview\[ra]].

.PP
\fB\-\-zero\fP=false
    If true, set the weight of all backends to zero.

  # Set two backend services on route 'web' with 2/3rds of traffic going to 'a'
  oc set route\-backends web a=2 b=1
  
  # Increase the traffic percentage going to b by 10% relative to a
  oc set route\-backends web \-\-adjust b=+10%
  
  # Set traffic percentage going to b to 10% of the traffic going to a
  oc set route\-backends web \-\-adjust b=10%
  
  # Set weight of b to 10
  oc set route\-backends web \-\-adjust b=10
