# Traffic shift step

Reference for the Shift Google Agent Runtime Traffic step.

The traffic shift step routes a percentage of traffic to the revision produced by the deploy step. Add a step for each stage of the canary, for example 10 percent, 25 percent, 50 percent, and 100 percent.

The step type is `ShiftGoogleAgentRuntimeTraffic`. Configure the following fields:

* **Container Registry:** A Harness connector for the registry that hosts the plugin image.
* **Image:** The traffic shift plugin image, `harness/google-agent-runtime-plugin:1.0.0-linux-amd64`.
* **Target Revision ID:** The revision produced by the deploy step, `<+steps.DeployGoogleAgentRuntimeRevision.agentDeployment.revisionId>`.
* **Weight (%):** The percentage of traffic to route to the target revision for this shift.
