尝试在标准 CI/CD 流的容器中执行 dotnet 构建时，我遇到了一个非常烦人的问题。这些问题似乎是“随机”发生的（从 Jenkins 运行时，平均大约 4/10 的构建失败，而两者之间的代码或配置没有任何更改）。我遇到的问题（在下面的堆栈跟踪中出现的问题似乎有点随机）：
- MSB4018：CreateAppHost 任务意外失败 - 最常发生

- NETSDK1029：无法使用 .../apphost 作为应用程序主机可执行文件，因为它不包含预期的占位符字节序列 - 我个人最喜欢 :)

关于现在，我想我已经浏览了所有的搜索结果，但到目前为止没有一个答案有帮助 - 所以也许在这里我会很幸运（并希望在此过程中帮助某人）。
技术数据：
Jenkins 代理
在 RHEL 8.4 和 Podman v. 3.2.3 上运行
容器数据
操作系统 - RHEL7.9 和 RHEL8.4（我都尝试过）使用来自 Jenkins 代理的挂载卷运行（包含从存储库克隆的源代码的目录）。基本 Dockerfile 设置，我使用内部存储库中的 RHEL8 基本映像 - RHEL7 是通过安装 scl-utils 等进行修改的，但总体思路是相同的
ARG rhel_version=7.9
ARG build_version=1.0.0
FROM <baseRHELimage>
ENV HOME=/opt/app-root/ \
DOTNET_APP_PATH=/opt/app-root/
#DOTNET_RUNNING_IN_CONTAINER=true
# Don't download/extract docs for nuget packages
ENV NUGET_XMLDOC_MODE=skip
RUN <setup yum repos>
dnf install -y dotnet-sdk-3.1 &&\
dnf update -y; dnf clean all
.NET 数据
使用 dotnet core 3.1 SDK
当我尝试运行 dotnet 构建时会出现这些问题。Jenkinsfile 首先在第一阶段删除所有 bin/ 和 obj/ 目录，然后为应用程序调用构建。
我尝试过的最有希望的事情：
- 有人建议需要完全删除文件夹 bin/ 和 obj/ - 这发生在运行前的第一阶段
- 我尝试将 dotnet publish 命令拆分为：
dotnet restore
dotnet build --no-restore
dotnet publish --no-build
... 使用dotnet build直接在构建中随机抛出这 3 个错误之一
我尝试使用不同的标志调用 dotnet 构建，例如“不并行”，认为线程可能是某种根本原因（我收到很多“进程无法访问文件，因为它正被另一个进程使用”警告 - 但这些发生了对于成功的构建 - 默认的 dotnet 重试似乎正在处理那些
有人知道我可能会错过什么吗？CI/CD 管道之前直接在 RHEL7.7 代理上运行（不使用容器）。现在我们想使用新版本的 RedHat 迁移到容器化构建 - 但这些随机重复出现的问题阻碍了我，所以如果有人有任何建议 - 非常感谢；）
