在CircleCI上更改用户

Question

这是扼杀我，找不到答案.我只是想将当前用户从根更改为预先创建的名为“节点”的用户，给出“节点:9”的基本图像。

下面是我现在拥有的. .circleci/config.yml文件：

# Javascript Node CircleCI 2.0 configuration file
#
# Check https://circleci.com/docs/2.0/language-javascript/ for more details
#
version: 2
jobs:
  build:
    docker:
      # specify the version you desire here
      - image: circleci/node:9

      # Specify service dependencies here if necessary
      # CircleCI maintains a library of pre-built images
      # documented at https://circleci.com/docs/2.0/circleci-images/
      # - image: circleci/mongo:3.4.4

    working_directory: ~/repo

    steps:
      - checkout
      - restore_cache:  # Download and cache dependencies
          keys:
          - v1-dependencies-{{ checksum "package.json" }}
          # fallback to using the latest cache if no exact match is found
          - v1-dependencies-

      - run: sudo npm install --loglevel=warn

      - save_cache:
          paths:
            - node_modules
          key: v1-dependencies-{{ checksum "package.json" }}

      # run tests!
      - run: echo "here are the tests"

下面是您如何处理Docker的方法：

RUN echo "newuser ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers
RUN useradd -ms /bin/bash newuser
USER newuser

但我相信节点:9张图片附带了一个预先创建的用户，所以可以简单地说：

 USER node
 WORKDIR /home/node/app

，但我找不到任何关于如何从根用户更改为CircleCI.的非根用户的文档。

下面是一些文档：https://circleci.com/docs/2.0/configuration-reference/

可以使用user参数在image部分中选择在停靠器映像中运行的可用用户。

docker:
  - image: circleci/node:9
    user: node
