Windows 2016主机,通过默认MSFTdocker提供程序运行Docker。 码头版本17.06.2-ee-5,构建508bb92 docker-构建版本1.17.1,构建6d101fb0
我有一个基于microsoft/windowsservercore:latest
的Windows容器,并试图为竹服务器设置一个映像。在创建构建计划期间,服务器生成一个密码,用于竹类和Bitbucket之间的通信。在正在运行的容器中,密码文件夹/文件生成失败,出现以下错误:
java.nio.file.AccessDeniedException: C:\bamboo-home\xml-data\configuration\cipher\cipher.key_0
我尝试将卷C:\bamboo-home
连接到我的Windows主机上,并将其完全包含在容器中。两次都犯了同样的错误。
Windows容器使用一个名为“容器管理员”的管理员帐户运行;在默认映像中和在使用入口点时都是这样,如下所示。
标准图像运行:
PS C:\> docker run -it microsoft/windowsservercore:latest powershell
Windows PowerShell Copyright (C) 2016 Microsoft Corporation. All
rights reserved.
PS C:\> whoami
user manager\containeradministrator
和用于测试入口点的自定义映像:
PS C:\test> docker-compose build
Building testentrypoint
Step 1/2 : FROM microsoft/windowsservercore:latest
---> 2cddde20d95d
Step 2/2 : ENTRYPOINT whoami

testentrypoint_1 | user manager\containeradministrator

据我所知,这个用户是管理员的别名,但有趣的是,它在net user
中没有显示为这个名称:
PS C:\> net user
User accounts for \\
-------------------------------------------------------------------------------
Administrator DefaultAccount Guest
The command completed with one or more errors.
因此,这是一个潜在的问题,但不管怎么说,根据我的判断,用户拥有完全的管理权限:
PS C:\> $user = [Security.Principal.WindowsIdentity]::GetCurrent()
PS C:\> $user

PS C:\> (New-Object Security.Principal.WindowsPrincipal $user).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)

因此,我尝试了以下方法::
每次在尝试生成密码文件之前,权限如下所示:
PS C:\> Get-ACL C:\bamboo-home\xml-data\configuration\ | fl
Path : Microsoft.PowerShell.Core\FileSystem::C:\bamboo-home\xml-data\configuration\
Owner : User Manager\ContainerAdministrator
Group : User Manager\ContainerAdministrator
Access : Everyone Allow FullControl
NT AUTHORITY\SYSTEM Allow FullControl

上述错误在尝试生成后发生,权限更改为:
PS C:\> Get-ACL C:\bamboo-home\xml-data\configuration\ | fl
Path : Microsoft.PowerShell.Core\FileSystem::C:\bamboo-home\xml-data\configuration\
Owner : User Manager\ContainerAdministrator
Group : User Manager\ContainerAdministrator

为什么默认帐户(可能是名为容器管理员的管理员)在它似乎表明它有所有权的情况下会失去对这个目录的访问权?为什么它不能首先创建文件(或文件夹),因为在这两种情况下,“每个人”都应该有完全的访问权限?

我没有识别主机/容器权限之间的问题,但是我提出容器的方式允许了这个问题的发生。通过更改我的设置过程,我能够纠正这个问题。
初始创建(创建文件夹的权限失败):
新创建(工作正常):
