8.9.2. 串行运行策略

将 runPolicy 字段设置为 Serial 将会导致从 Build 配置创建的所有新构建按顺序运行。这意味着每次只有一个构建运行，每次新构建将等候到上一构建完成。使用此策略将导致一致且可预测的构建输出。这是默认的 runPolicy。

使用 Serial 策略从 sample-build 配置触发三个构建将导致：

NAME             TYPE      FROM          STATUS    STARTED          DURATION
sample-build-1   Source    Git@e79d887   Running   13 seconds ago   13s
sample-build-2   Source    Git           New
sample-build-3   Source    Git           New

当 sample-build-1 构建完成时，sample-build-2 构建将运行：

NAME             TYPE      FROM          STATUS    STARTED          DURATION
sample-build-1   Source    Git@e79d887   Completed 43 seconds ago   34s
sample-build-2   Source    Git@1aa381b   Running   2 seconds ago    2s
sample-build-3   Source    Git           New
