NAME¶
oc set route-backends - Update the backends for a route
SYNOPSIS¶
oc set route-backends [OPTIONS]
DESCRIPTION¶
Set and adjust route backends.
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.
When setting backends, the first backend is the primary and the other backends are considered alternates. For example:
$ oc set route-backends web prod=99 canary=1
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".
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.
Not all routers may support multiple or weighted backends.
OPTIONS¶
--adjust=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.
--all=false
If true, select all resources in the namespace of the specified resource
types
--allow-missing-template-keys=true
If true, ignore any errors in templates when a field or map key is missing in
the template. Only applies to golang and jsonpath output formats.
--dry-run="none"
Must be "none", "server", or "client". If
client strategy, only print the object that would be sent, without sending
it. If server strategy, submit server-side request without persisting the
resource.
--equal=false
If true, set the weight of all backends to 100.
--field-manager="kubectl-set"
Name of the manager used to track field ownership.
-f, --filename=[]
Filename, directory, or URL to files to use to edit the resource
-k, --kustomize=""
Process the kustomization directory. This flag can't be used together with -f
or -R.
--local=false
If true, set image will NOT contact api-server but run locally.
-o, --output=""
Output format. One of: (json, yaml, name, go-template, go-template-file,
template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).
-R, --recursive=false
Process the directory used in -f, --filename recursively. Useful when you
want to manage related manifests organized within the same directory.
-l, --selector=""
Selector (label query) to filter on
--show-managed-fields=false
If true, keep the managedFields when printing objects in JSON or YAML
format.
--template=""
Template string or path to template file to use when -o=go-template,
-o=go-template-file. The template format is golang templates [
⟨http://golang.org/pkg/text/template/#pkg-overview⟩].
--zero=false
If true, set the weight of all backends to zero.
OPTIONS INHERITED FROM PARENT COMMANDS¶
--as=""
Username to impersonate for the operation. User could be a regular user or a
service account in a namespace.
--as-group=[]
Group to impersonate for the operation, this flag can be repeated to specify
multiple groups.
--as-uid=""
UID to impersonate for the operation.
--cache-dir="/home/abuild/.kube/cache"
Default cache directory
--certificate-authority=""
Path to a cert file for the certificate authority
--client-certificate=""
Path to a client certificate file for TLS
--client-key=""
Path to a client key file for TLS
--cluster=""
The name of the kubeconfig cluster to use
--context=""
The name of the kubeconfig context to use
--disable-compression=false
If true, opt-out of response compression for all requests to the server
--insecure-skip-tls-verify=false
If true, the server's certificate will not be checked for validity. This will
make your HTTPS connections insecure
--kubeconfig=""
Path to the kubeconfig file to use for CLI requests.
--match-server-version=false
Require server version to match client version
-n, --namespace=""
If present, the namespace scope for this CLI request
--profile="none"
Name of profile to capture. One of
(none|cpu|heap|goroutine|threadcreate|block|mutex)
--profile-output="profile.pprof"
Name of the file to write the profile to
--request-timeout="0"
The length of time to wait before giving up on a single server request.
Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h).
A value of zero means don't timeout requests.
-s, --server=""
The address and port of the Kubernetes API server
--tls-server-name=""
Server name to use for server certificate validation. If it is not provided,
the hostname used to contact the server is used
--token=""
Bearer token for authentication to the API server
--user=""
The name of the kubeconfig user to use
--warnings-as-errors=false
Treat warnings received from the server as errors and exit with a non-zero
exit code
EXAMPLE¶
# Print the backends on the route 'web'
oc set route-backends web
# 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
# Set the weight to all backends to zero
oc set route-backends web --zero
