修复剧本中的错误后如何继续执行失败的任务? [英] How to continue execution on failed task after fixing error in playbook?

问题描述

在编写和调试 Ansible playbook 时，典型的工作流程如下:

When writing and debugging Ansible playbooks, typical workflow is as follows:

1. ansible-playbook ./main.yaml
2. Playbook 在某些任务上失败
3. 修复此任务并重复第 1 行，等待所有先前的任务再次执行.这需要很多时间

理想情况下，我想恢复执行失败的任务，拥有清单和以前任务收集的所有事实.甚至有可能吗?如何使剧本编写/调试更快?

Ideally, i'd like to resume execution on failed task, having inventory and all facts collected by previous tasks. Is it even possible? How to make playbook writing/debugging faster?

推荐答案

看一看 执行故障排除手册.如果您想在特定任务上开始执行您的剧本，您可以使用 --start-at-task 选项:

Take a look at Executing playbooks for troubleshooting. If you want to start executing your playbook at a particular task, you can do so with the --start-at-task option:

ansible-playbook playbook.yml --start-at-task="install packages"

以上将在名为安装包"的任务中开始执行您的剧本.

The above will start executing your playbook at a task named "install packages".

或者，看看这个以前的答案 如何在 ansible playbook 中只运行一项任务?

Alternatively, take a look at this previous answer How to run only one task in ansible playbook?

最后，当一个游戏失败时，它通常会给你一些类似的东西:

Finally, when a play fails, it usually gives you something along the lines of:

PLAY RECAP ******************************************************************** 
           to retry, use: --limit @/home/user/site.retry

使用那个 --limit 命令，它应该从失败的任务中重试.

Use that --limit command and it should retry from the failed task.
