当我运行任何带有管道或重定向的命令时,它失败了。
master和minion都在Digital Ocean上运行新的Ubuntu 14.04盒子,这些盒子是为了测试Salt而创建的。
两者都是使用引导脚本从 git 中提取最新分支安装的。
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).
它在没有管道的情况下工作正常,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'

来自cmd.run
文档(强调我的):
警告:此函数不通过 shell 处理命令 除非python_shell标志设置为 True。这意味着任何 外壳特定的功能,例如"回声"或使用管道, 重定向或 &&,应迁移到 cmd.shell 或具有 python_shell=此处设置了真标志。
