我有一个FastAPI应用程序，我已经为其配置了Jenkins管道。当我在启用代码覆盖率的情况下执行单元测试时，它们会失败，并出现以下错误：

Jenkins菲尔

pipeline {
 agent any
  
triggers {
    githubPush()
}
stages {
    
    stage('Setup'){
       steps{
       withPythonEnv('/usr/bin/python3.8') {
            sh 'echo "Job is starting" '
        }            
        }
     }    
stage('Unit Tests'){ 
           steps{
               withPythonEnv('/usr/bin/python3.8') {
                 sh '''pip install -r requirements.txt
                       sudo chown -R jenkins:jenkins ./docs/unit-tests/htmlcoverage
                       pytest -v --junitxml=docs/unit-tests/htmlcoverage/coverage.xml --cov-report xml --cov app.main
                '''
             }           
            }                    
         }                
       stage('Publish Test Report'){ 
           steps{
              cobertura autoUpdateHealth: false, autoUpdateStability: false, coberturaReportFile: 'coverage*.xml', conditionalCoverageTargets: '70, 0, 0', failUnhealthy: false, failUnstable: false, lineCoverageTargets: '80, 0, 0', maxNumberOfBuilds: 0, methodCoverageTargets: '80, 0, 0', onlyStable: false, sourceEncoding: 'ASCII', zoomCoverageChart: false
              archiveArtifacts artifacts: 'docs/unit-tests/htmlcoverage/*.*'
            }                    
         }        

      }
}

我添加了 sudo chown -R jenkins：jenkins ./docs/unit-tests/htmlcoverage 行，因为我遇到了覆盖文件的权限错误：

INTERNALERROR> PermissionError: [Errno 13] Permission denied: 'coverage.xml'

我还验证了coverage.xml是root用户，而不是常规的jenkins用户（是什么原因导致的？）：

我尝试过的：

echo “jenkins ALL=(ALL) NOPASSWD: ALL” >> /etc/sudoers

这将导致相同的错误sudo: a terminal is required to read the password; either use the -S option to read from standard input or configure an askpass helper

echo “jenkins ALL= NOPASSWD: ALL” >> /etc/sudoers

这也会导致相同的错误sudo: a terminal is required to read the password; either use the -S option to read from standard input or configure an askpass helper
在这两种情况下，我都重新启动了jenkins服务。jenkins用户也已经添加到sudo组。
我到底错过了什么

由于docs文件夹属于root，所以需要root来清理，可以添加临时stage来清理，如下所示，一旦确定管道不会使用root，就可以移除临时stage

stage('Clean Test Report') {
    steps {
        sh '''
            docker run -t \
                -u root \
                -v "$(pwd)":"$(pwd)" \
                -w "$(pwd) \
                --entrypoint='' \
                <what ever a docker image> \
                rm -rf docs
        '''
    }
}

stage('Unit Tests'){ 
   steps{
       withPythonEnv('/usr/bin/python3.8') {
         sh '''
            ls -al
            pip install -r requirements.txt
            pytest -v \
                --junitxml=docs/unit-tests/htmlcoverage/coverage.xml \
                --cov-report xml \
                --cov app.main
        '''
     }           
    }                    
}

要阻止管道以root用户身份运行容器，可以执行以下操作

# run container by sh step
sh '''
  docker run \
    -u $(id -u):$(id -g) \
    -v /etc/passwd:/etc/passwd \
    ...
'''

# run container by docker global variable
container = docker.image(<image>).run(
    '-u $(id -u):$(id -g) -v /etc/passwd:/etc/passwd -t', 
    'cat'
)

docker.image(<image>).withRun(
   '-u $(id -u):$(id -g) -v /etc/passwd:/etc/passwd -t', 'cat') { container ->
   sh """
      docker exec -it ${container.id} -c \
        "pip install .. \
         pytest ..
        "
   """
}

docker.image(<image>).inside('-v /etc/passwd:/etc/passwd') {
# inside() run container as current host user by default

   sh '''
      pip install .. \
      pytest ...
   '''
}

# specify container as agent
# which runs container as current host user by default
agent {
   docker {
     args: '-v /etc/passwd:/etc/passwd'
   }   
}

agent {
   dockerfile {
     args: '-v /etc/passwd:/etc/passwd'
   }   
}

对于任何正在努力解决这个问题的人来说，问题在于/etc/sudoers内部的规则优先级。
默认情况下 * 如果/etc/sudoers文件中有多个用户条目，sudo将使用最后一个规则 *
由于规则在/etc/sudoers中的位置，对jenkins用户的更改被覆盖：
