Docker 和 CircleCI 2.0 的高 uid 错误问题

Question

我正在尝试使用 Circle Ci 构建持续集成流程。当我将我的代码推送到 github 时，流程开始，但因错误而停止：

CircleCI was unable to start the container because of a userns remapping failure in Docker.

This typically means the image contains files with UID/GID values that are higher than Docr and CircleCI can use.

Checkout our docs https://circleci.com/docs/2.0/high-uid-error/ to learn how to fix this problem.

Original error: failed to register layer: Error processing tar file(exit status 1): Container ID 5924152 cannot be mapped to a host ID

我按照 link 并按照那里的建议进行操作，但我找不到任何具有该 ID 的内容。

这是我的配置圈 yml 文件：

version: 2

jobs:
  build:
    docker:
      - image: micheleminno/elasticsearch:latest
      - image: mysql:5.5
        environment:
          MYSQL_ROOT_PASSWORD: password
          MYSQL_DATABASE: real-affinities-test
          MYSQL_USER: development
          MYSQL_PASSWORD: development
      - image: micheleminno/db-migrations
        environment:
          - NODE_ENV: development

    working_directory: ~/

    steps:
      - checkout
      - run:
          name: Build real-affinities and run tests
          command: docker-compose -f docker-compose.test.yml -p ci up --build

2017 年 9 月 9 日更新：

我按照@FelicianoTech 的建议直接在 Dockerfile 中更改文件的所有权，更新了导致高 uids 问题的项目的 Dockerfile：

FROM node:8.1.4-alpine

WORKDIR /app

# add package.json and run npm install before adding the rest of the files
# this way, you only run npm install when package.json changes
ADD package.json /app
RUN npm install

# add the rest of the files
ADD . /app

# change ownership recursively of all files
RUN chown root:root . -R

CMD ["./node_modules/.bin/knex", "migrate:latest"]

但问题依旧。

问题出在第三张 Docker 图片 micheleminno/db-migrations 上。如果您运行本地图像，并且运行此命令：

ls -lah /app/node_modules/

您会看到几个目录的用户 ID 高于 65534。这就是问题所在。将这些 ID 更改为更低的 ID 以解决此问题。
