我正在基于ubuntu创建一个自定义docker映像(testing：latest).我想为流星应用程序运行一些单元测试.

FROM ubuntu:16.04
RUN apt-get update -y && \
    apt-get install -yqq --no-install-recommends apt-transport-https ca-certificates curl nodejs-legacy && \
    apt-get clean && apt-get autoclean && apt-get autoremove && \
    curl https://install.meteor.com/ | sh && \
    meteor npm install eslint eslint-plugin-react && \
    apt-get remove -y apt-transport-https ca-certificates curl && \
    rm -rf /var/lib/apt/lists/*

我正在使用dockerrunner使用gitlab CI.所以我的yml文件看起来像

stages:
  - test

lint:
  image: testing:latest
  stage: test
  script:
    - /node_modules/.bin/eslint --ext .js --ext .jsx .
  except:
    - master

unit:
  image: testing:latest
  stage: test
  script:
    - whoami
    - meteor test --driver-package=practicalmeteor:mocha-console-runner
  except:
    - master

运行whoami向我显示当前用户是root.因此流星测试未在运行,因为它不应与root一起使用

You are attempting to run Meteor as the 'root' superuser. If you are
developing,this is almost certainly *not* what you want to do and will likely
result in incorrect file permissions. However,if you are running this command
in a build process (CI,etc.),or you are absolutely sure you know what you are
doing,set the METEOR_ALLOW_SUPERUSER environment variable or pass
--allow-superuser to proceed.

Even with METEOR_ALLOW_SUPERUSER or --allow-superuser,permissions in your app
directory will be incorrect if you ever attempt to perform any Meteor tasks as
a normal user. If you need to fix your permissions,run the following command
from the root of your project:

  sudo chown -Rh <username> .meteor/local

如何使用其他用户？我必须在dockerfile中这样做吗？还是我必须在yml文件中添加一些命令？
