在Google Cloud Build中可以动态生成标签吗？

{
  "steps": [
    {
      "name": "gcr.io/cloud-builders/docker",
      "args": [
        "build",
        "-t",
        "gcr.io/$PROJECT_ID/$IMAGE_NAME:$BUILD_ID",
        "."
      ]
    }
  ]
}

{
  "steps": [
    {
      "name": "gcr.io/cloud-builders/docker",
      "args": [
        "build",
        "-t",
        "gcr.io/$PROJECT_ID/$IMAGE_NAME:{$PARAM_NAME}",
        "."
      ]
    }
  ]
}
