概述
特性标记安全发布工作流是一个中级难度的工作流。用特性标记按百分比渐进发布新功能，支持即时回滚。该工作流的目标是：Deploy a new feature safely using gradual rollout with the ability to instantly roll back.
环境准备
执行本工作流需要以下环境：A feature flag system；A new feature behind a flag；Monitoring and alerting for the feature。请确保在开始前准备好所有必需的工具和资源，以避免中途因环境问题中断。
执行步骤
本工作流包含5个步骤。步骤1：Create the flag——Create a feature flag in the flag system with a description and owner. 步骤2：Roll out to 5 percent——Enable the flag for 5 percent of users and monitor for errors. 步骤3：Gradually increase——Increase the rollout percentage in stages: 25, 50, 75, 100 percent. 步骤4：Monitor each stage——Check error rates, performance, and user feedback at each stage before proceeding. 步骤5：Full rollout or rollback——Complete the rollout at 100 percent or roll back instantly if issues are detected.
验证与清理
预期结果：The new feature is safely rolled out to all users, or rolled back, with minimal risk at each stage.。验证方法：Monitor error rates and performance metrics at each rollout stage; confirm the flag can be turned off instantly.。清理操作：Disable the feature flag if issues are detected; clean up the flag after full successful rollout.。estimatedMinutes 为 45 分钟。
