azure-devops - Azure devops 托管代理可疑主机文件

Question

这可能是一个奇怪的问题，但请听我说。我正在使用 Azure Devops Hosted Agent 进行持续部署。在发布期间，我有一项任务是在托管代理上的主机文件中添加一行。以前的主机文件看起来像这样:

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#   127.0.0.1       localhost
#   ::1             localhost 
xx.xxx.x.xx mydomain.net

正如您在 powershell 中看到的那样，我将 mydomain.net IP 添加到主机文件中。这在很长一段时间内都运行良好。

最近我的发布开始失败，因为它错误地更新了主机文件。我检查了托管代理上的主机文件，现在它看起来像这样:

尽管我可以通过向我的 powershell 脚本添加新的行分隔符来解决这个问题，但我更感兴趣的是那些添加到主机文件的地址是什么？我的印象是，当我选择托管代理时，Azure 会为我提供新机器，对吗？谁可以给我解释一下这个？或者这是托管代理防止某些加密挖矿的新方法？

编辑:

这是我正在使用的 powershell 脚本:

$file = "$env:windir\System32\drivers\etc\hosts"
"xx.xxx.x.xx mydomain.net" | Add-Content -PassThru $file
Get-Content -Path $file

Answer 1

Microsoft 最近取消了对托管代理的按小时付费限制。由于有无限的免费托管代理分钟数，他们必须采取一些措施来防止他们的毛钱被加密挖掘。

我没有官方证实这一点，但它似乎很合乎逻辑。
