No such user git commit error in Jenkinsfile

Question

I'm trying to run npm version in a node:10 Docker container as part of a Jenkinsfile and am getting the following error.

npm ERR! fatal: unable to look up current user in the passwd file: no such user

Is there a way to allow git to look for the user another way?

Answer 1

Without testing, I can't guarantee this, but it should guide you in the right direction:

Jenkins starts the docker container without a user (using the UID and GID), so you can start it with root (or add a new user in your Dockerfile which is better):

agent {
    docker {
        image 'node:10'
        args  '--user root'
    }
}

Another option is that you can set these environment variables:

export GIT_COMMITTER_NAME=’user_name’
export GIT_COMMITTER_EMAIL=’user_email’

You can add these as part of the Jenkinsfile or Dockerfile
