Traffic Configuration Instructions

CloudBase Cloud Run supports traffic allocation by percentage and by URL parameters, enabling developers to implement features such as canary release and blue-green deployment.

Allocate Traffic by Percentage (Random)​

  • Click Traffic Configuration.
  • Mode defaults to by Percentage.
  • Select the latest version just deployed and the old version currently running, then specify a traffic percentage for each version. The sum of all percentages must equal 100% or 0%, otherwise the configuration cannot be completed. For versions not added in the traffic configuration window, their traffic percentages will be uniformly set to 0%.
  • Click Complete, and the system will immediately begin randomly allocating traffic by percentage, redirecting part of the traffic from the old version to the new version.

    /> After a successful operation, you can see that the traffic percentage for the corresponding version has changed.

Allocate Traffic by URL Parameters (Targeted)​

  • Click Traffic Configuration.
  • Select by URL parameters for the mode.
  • Add the latest deployed version, set the URL parameter key and value (Glob expressions supported). Requests meeting the conditions will be routed to the new version.
  • Add the old version currently running and the corresponding URL parameters.
  • Set the old version as the default version.
  • In "Match Result Prediction", input URL parameters to simulate a request, click Predict to view the corresponding version and debug the configuration.
  • Click Complete, and the system will immediately begin redirecting part of the traffic from the old version to the new version.

    /> After a successful operation, you can see that the traffic conditions for the corresponding version have changed. />
