     <td>Used to compute the number of replicas of &#39;-baseline&#39; and &#39;-canary&#39; variants of the workloads found in manifest files. For the specified percentage input, if (percentage * numberOfDesirerdReplicas)/100 is not a round number, the floor of this number is used while creating &#39;-baseline&#39; and &#39;-canary&#39;.<br/><br/>For example, if Deployment hello-world was found in the input manifest file with &#39;replicas: 4&#39; and if &#39;strategy: canary&#39; and &#39;percentage: 25&#39; are given as inputs to the action, then the Deployments hello-world-baseline and hello-world-canary are created with 1 replica each. The &#39;-baseline&#39; variant is created with the same image and tag as the stable version (4 replica variant prior to deployment) while the &#39;-canary&#39; variant is created with the image and tag corresponding to the new changes being deployed</td>

     <td>The number of baseline and canary replicas. Percentage traffic split is controlled in the service mesh plane, the actual number of replicas for canary and baseline variants could be controlled independently of the traffic split. For example, assume that the input Deployment manifest desired 30 replicas to be used for stable and that the following inputs were specified for the action </br></br><code>&nbsp;&nbsp;&nbsp;&nbsp;strategy: canary<br>&nbsp;&nbsp;&nbsp;&nbsp;trafficSplitMethod: smi<br>&nbsp;&nbsp;&nbsp;&nbsp;percentage: 20<br>&nbsp;&nbsp;&nbsp;&nbsp;baselineAndCanaryReplicas: 1</code></br></br> In this case, stable variant will receive 80% traffic while baseline and canary variants will receive 10% each (20% split equally between baseline and canary). However, instead of creating baseline and canary with 3 replicas, the explicit count of baseline and canary replicas is honored. That is, only 1 replica each is created for baseline and canary variants.</td>
