Question

我在EC2实例上运行一个jenkins容器并执行一个简单的管道来测试和部署一个简单的flask应用程序。我正在使用具有Jenkinsfile的git repo。使用管道，我正在一个临时容器中构建和测试，然后将其部署为容器应用程序。这是Jenkins文件。

pipeline {
  agent {
    dockerfile {
      filename "Dockerfile"
      args '-i --entrypoint='
               }
        }
  stages {
    stage('build') {
      steps {
        echo 'hello world'
      }
    }
    stage('test') {
      steps {
        sh 'python3 test.py'
      }
      post {
        always {
          junit 'test-results/*.xml'
        }
      }
    }
    stage('Deploy') {
      steps {
        sh 'echo $PATH'
        sh 'whoami'
      }
    }
 }

我正在尝试使用'sh'执行docker命令，但是jenkins生成日志说找不到命令，这很奇怪，因为我已经确认使用docker安装在jenkins容器中 sudo docker exec -it jenkins /bin/sh 接着 which docker 输出'/ usr / bin / docker'

经过一番调查后，由于$ PATH值与构建日志中的jenkins容器不同，因此似乎在容器内执行了“ sh”命令。这是上面Jenkinsfile的构建日志。

BOTTOMLINE：我想在成功测试后部署烧瓶容器，但是我不确定该怎么做。我尝试执行“码头工人”，但失败，并说“找不到命令”。

如果需要，这里是Dockerfile的内容。

FROM python:3.7.6

# Create app directory
WORKDIR /usr/src/app
ADD . /usr/src/app

# Install app dependencies
RUN pip install -r requirements.txt


EXPOSE 5000
ENTRYPOINT ["python"]
CMD ["app.py"]

在詹金斯容器中，$ PATH为 /usr/local/openjdk-8/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

无法在jenkins容器内执行docker命令（找不到docker命令）
