You could ignore errors on <code>wait_for</code> and register the result to force kill failed items:

<pre><code>- name: Get running processes
 shell: "ps -ef | grep -v grep | grep -w {{ PROCESS }} | awk '{print $2}'"
 register: running_processes

- name: Kill running processes
 shell: "kill {{ item }}"
 with_items: "{{ running_processes.stdout_lines }}"

- wait_for:
 path: "/proc/{{ item }}/status"
 state: absent
 with_items: "{{ running_processes.stdout_lines }}"
 ignore_errors: yes
 register: killed_processes

- name: Force kill stuck processes
 shell: "kill -9 {{ item }}"
 with_items: "{{ killed_processes.results | select('failed') | map(attribute='item') | list }}"
</code></pre>

The <code>killall</code> command has a wait option that might be useful.
Install psmisc:
<pre><code>tasks:
 - apt: pkg=psmisc state=present
</code></pre>
Then use killall like this:
<pre><code>tasks:
 - shell: &quot;killall screen --wait&quot;
 ignore_errors: true # In case there is no process
</code></pre>
<code>-w, --wait</code>:
Wait for all killed processes to die. killall checks once per second if any of the killed processes still exist and only returns if none are left.

I have an ansible playbook to kill running processes and works great most of the time!, however, from time to time we find processes that just can't be killed so, "wait_for" gets to the timeout, throws an error and it stops the process. 

The current workaround is to manually go into the box, use "kill -9" and run the ansible playbook again so I was wondering if there is any way to handle this scenario from ansible itself?, I mean, I don't want to use kill -9 from the beginning but I maybe a way to handle the timeout?, even to use kill -9 only if process hasn't been killed in 300 seconds? but what would be the best way to do it?

These are the tasks I currently have: 

<pre><code>- name: Get running processes
 shell: "ps -ef | grep -v grep | grep -w {{ PROCESS }} | awk '{print $2}'"
 register: running_processes

- name: Kill running processes
 shell: "kill {{ item }}"
 with_items: "{{ running_processes.stdout_lines }}"

- name: Waiting until all running processes are killed
 wait_for:
 path: "/proc/{{ item }}/status"
 state: absent
 with_items: "{{ running_processes.stdout_lines }}"
</code></pre>

Thanks!

我有一个ansible剧本来杀死正在运行的进程，并且大部分时间工作得很好！然而，我们不时地发现无法被杀死的进程，因此，"wait_for“到达超时，抛出一个错误并停止该进程。目前的解决办法是手动进入盒子，使用“杀死-9”，然后再次运行“ansible剧本”，所以我想知道是否有任何方法可以从ansible本身处理这个场景...
