Question

如何对Chef批处理资源的not_if和run_if进行评估？我想创建一个新的Windows服务，除非它已经存在

action :enable do
  batch "install Windows service nexus3_nexus" do
    code "c:/Nexus3/nexus-3.14.0-04/nexus.exe /install nexus3_nexus"
    action :run
    not_if "sc.exe query nexus3_nexus"
  end

据我了解文档，如果“ sc.exe query nexus3_nexus”退出代码为<> 0-字符串作为shell命令执行，则应运行批处理命令。如果命令返回0，则应用防护。 但是，似乎该命令虽然返回0，但仍会应用该代码：

c:\Nexus3\nexus-3.14.0-04\bin>sc.exe query nexus3_ne

SERVICE_NAME: nexus3_nexus
        TYPE               : 110  WIN32_OWN_PROCESS
        STATE              : 4  RUNNING
                                (STOPPABLE, NOT_PAUS
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0

c:\Nexus3\nexus-3.14.0-04\bin>echo %errorlevel%
0

在Chef-client-run的输出下方：

* batch[install Windows service nexus3_nexus] action run[2018-12-[12T11:16:30+01:00] INFO: Processing batch[install Windows service nexus3_nexus] action run (c:/chef/cache/cookbooks/my_nexus/resources/service_windows.rb line 11)

not_if和run_if用于批处理资源
