Routing and managing traffic by using the Knative CLI
You can use the following kn CLI command to split traffic between revisions:
$ kn service update –traffic =
For example, to split traffic for a Service named example, by sending 80% of traffic to the Revision green and 20% of traffic to the Revision blue, you could run the following command:
$ kn service update example-service –traffic green=80 –traffic blue=20
It is also possible to add tags to Revisions and then split traffic according to the tags you have set:
$ kn service update example –tag revision-0001=green –tag @latest=blue
The @latest tag means that blue resolves to the latest Revision of the Service. The following example sends 80% of traffic to the latest Revision and 20% to a Revision named v1.
$ kn service update example-service –traffic @latest=80 –traffic v1=20
The following example shows a traffic spec where 100% of traffic is routed to the latestRevision of the Service. Under status you can see the name of the latest Revision that latestRevision was resolved to:
The following example shows a traffic spec where 100% of traffic is routed to the current Revision, and the name of that Revision is specified as example-service-1. The latest ready Revision is kept available, even though no traffic is being routed to it:
The following example shows how the list of Revisions in the traffic spec can be extended so that traffic is split between multiple Revisions. This example sends 50% of traffic to the current Revision, example-service-1, and 50% of traffic to the candidate Revision, example-service-2:
