Question

我的Jenkins在Docker中运行。我有一个只有npm install的简单Dockerfile。

我使用声明性Jenkins管道，因此它可以构建并运行容器，但是当我运行npm run test时，Jenkins会抛出错误，表明Jest不存在，并且

npm WARN Local package.json exists, but node_modules missing, did you mean to install?

尽管应该在映像构建node_modules期间安装

Step 4/5 : RUN npm install --unsafe-perm ---> Using cache。

Dockerfile

WORKDIR /app
COPY package*.json /app/
RUN npm install --unsafe-perm
COPY ./ /app/

Jenkinsfile

pipeline {
    agent {
        dockerfile {
            filename 'docker/Dockerfile.test'
            dir '.'
        }
    }
    stages {
        stage ('Test') {
            steps {
                sh 'npm run test'
            }
        }
    }
}

Jenkins控制台输出

正如其他人所述，here尝试在npm init之前使用npm install。 npm init会动态创建package.json。

使用声明性Jenkins Pipeline在Docker中运行命令
