Running a command as root in JenkinsFile

I have a command which requires root in JenkinsFile.But when i run it on my localhost it gives error that "sudo not found".The JenkinsFile is in the source code.

stage('Install packages') {
  sh("docker run --rm -v `pwd`:/app -w /app node yarn install")
  sh("sudo chown -R jenkins: ./node_modules")
}

I have already tried this. How to run a script as root in Jenkins? The temp sh script is created on each build. And the error is

/var/jenkins_home/workspace/boilerplate_master-2ESKZDF4PBIXGKODFFKIVAND5RN5VWF6QLEGRZ44LZGESCULVC4Q@tmp/durable-14d87eaa/script.sh: line 1: sudo: not found

You are seeing "sudo not found" since sudo is not installed on your docker image. Check the default user's ID.
i.e. For Maven, it is the root user (ID: 0).

The user may be mapped to ID, and not name.
i.e. The user ID on host is 1000, which corresponds to the user node in the image.

sh “chown -R 1000 /mydir”  /* Replace 1000 with actual user ID> */

The above command will solve your issue if the user IDs match, or else it will set an unknown owner to your files.

Please try the following Jenkins script I wrote based on the Docker image you provided.

pipeline{
agent any
stages{
    stage('test'){
        steps{
            script{
                    def image = docker.image('mhart/alpine-node:8.11.3')
                    image.pull()
                    image.inside() {
                        sh 'id'
                        sh 'ls -lrt'
                        sh 'node yarn install'
                    }
              }
          }
      }
    }
}

try to run such commands as 'jenkins' user instead:

stage('Install packages') {
  sh("docker run --user='jenkins' --rm -v `pwd`:/app -w /app node yarn install")
}
