13.3.2.2.4. 金丝雀集群测试
要在金丝雀群集上测试更新，然后再将其推广到完整机群，请在 remediationStrategy 下添加一个金丝雀列表，并使用 clusterSelector 而不是群集按标签将目标群集添加到：
clusterSelector:
- <label_selector>
remediationStrategy:
canaries:
- <canary_cluster_name>
maxConcurrency: 1其中：
-
<label_selector>:为目标群集指定标签选择器，例如upgrade-wave=1。 -
<canary_cluster_name>: 指定要首先更新的金丝雀群集的名称。TALM首先更新金丝雀群集，等待成功，然后继续其他群集。
