ansible - 有没有办法让角色在戏剧中成功之前？

Question

我有一个角色名称 system_check。
系统启动后，我需要等到这个角色成功。
有没有办法重复运行这个角色直到它成功？

Answer 1

Q: "Is there a way to running a role until it succeeds in a play?"

答:这是不可能的。模块 include_role说

Ignores some keywords, like until and retries.

相反，请使用 ansible-runner .例如 Use Runner as a standalone command line tool并测试 artifacts (rc，状态，标准输出)。

例如

#!/bin/bash

rcfile=private1/artifacts/ID01/rc
statusfile=private1/artifacts/ID01/status

    ansible-runner -p test.yml -i ID01 run private1
    rc=$(cat $rcfile)
    echo "rc: $rc"

    until [ "0"  == "$rc" ]; do
        ansible-runner -p test.yml -i ID01 run private1
        rc=$(cat $rcfile)
        echo "rc: $rc"
    done
