Saltstack:忽略cmd.run的结果

Question

我试图通过Saltstack调用配置命令.如果命令失败,那么我得到状态失败,我不希望它(命令的重新编码无关紧要).

目前我有以下解决方法:

Run something:
  cmd.run:
    - name: command_which_can_fail || true

有没有办法使用salt功能使这种状态忽略retcode？或者我可以从日志中排除这种状态？

用途check_cmd:

fails:
  cmd.run:
    - name: /bin/false

succeeds:
  cmd.run:
    - name: /bin/false
    - check_cmd:
      - /bin/true

输出:

local:
----------
          ID: fails
    Function: cmd.run
        Name: /bin/false
      Result: False
     Comment: Command "/bin/false" run
     Started: 16:04:40.189840
    Duration: 7.347 ms
     Changes:
              ----------
              pid:
                  4021
              retcode:
                  1
              stderr:

              stdout:

----------
          ID: succeeds
    Function: cmd.run
        Name: /bin/false
      Result: True
     Comment: check_cmd determined the state succeeded

              retcode:
                  1
              stderr:

              stdout:

Failed:    1

Total states run:     2

Answer 2

如果你不关心命令的结果是什么，你可以使用：

Run something:
 cmd.run:
    - name: command_which_can_fail; exit 0

这在 Salt 2017.7.0 中进行了测试，但可能适用于早期版本。
