Salt无法使用管道或重定向执行命令

Question

当我使用管道或重定向运行任何命令时,它会失败.

master和minion都在Digital Ocean上的新Ubuntu 14.04盒子上运行,以测试Salt.

两者都是使用引导脚本从git中提取最新分支来安装的.

这是我得到的:

# salt-call --local cmd.run "ps aux | grep hello" -l debug
[DEBUG   ] Reading configuration from /etc/salt/minion
[DEBUG   ] Using cached minion ID from /etc/salt/minion_id: XXX.XXX.XX
[DEBUG   ] Configuration file path: /etc/salt/minion
[DEBUG   ] Reading configuration from /etc/salt/minion
[DEBUG   ] Failed to import module debian_service. The exeception was No module named systemd. Another attempt will be made to try to resolve dependencies.
[DEBUG   ] compile template:
[ERROR   ] Template does not exist:
[INFO    ] Executing command 'ps aux | grep hello' in directory '/root'
[ERROR   ] Command 'ps aux | grep hello' failed with return code: 1
[ERROR   ] output: error: garbage option

Usage:
  ps [options]

  Try 'ps --help <simple|list|output|threads|misc|all>'
  or 'ps --help <s|l|o|t|m|a>'
  for additional help text.

For more details see ps(1).

没有管道它工作正常,但显然返回完整的输出.

尝试使用python_shell=True或cmd.shell:

root@323be0968814:/# salt-call --local cmd.run "ps aux | grep hello" python_shell=True
[INFO    ] Executing command 'ps aux | grep hello' in directory '/root'
local:
    root      4796  0.0  0.1 134688 24200 ?        S+   14:50   0:00 /usr/bin/python /usr/bin/salt-call --local cmd.run ps aux | grep hello python_shell=True
    root      4819  0.0  0.0   4444   652 ?        S+   14:50   0:00 /bin/sh -c ps aux | grep hello
    root      4821  0.0  0.0   4444   104 ?        R+   14:50   0:00 /bin/sh -c ps aux | grep hello

root@323be0968814:/# salt-call --local cmd.shell "ps aux | grep hello" 
[INFO    ] Executing command 'ps aux | grep hello' in directory '/root'
local:
    root      4822  0.0  0.1 134688 24204 ?        S+   14:52   0:00 /usr/bin/python /usr/bin/salt-call --local cmd.shell ps aux | grep hello
    root      4845  0.0  0.0   4444   648 ?        S+   14:52   0:00 /bin/sh -c ps aux | grep hello
    root      4847  0.0  0.0   4444   100 ?        R+   14:52   0:00 /bin/sh -c ps aux | grep hello

从该cmd.run文档(重点煤矿):

警告:除非python_shell标志设置为True,否则此函数不会通过shell处理命令.这意味着任何特定于shell的功能(如"echo"或管道,重定向或&&的使用)都应迁移到cmd.shell或在此处设置python_shell = True标志.
