如何运行 docker-compose inside docker in docker which 运行s inside gitlab-运行ner container？

Question

我在 docker 容器中有一个 gitlab 运行ner，运行如果我运行像 nginx 这样的图像就没问题。但是现在我试图运行 docker in docker (dind) inside the gitlab 运行ner 我想运行 docker-compose inside笨蛋。 Docker 信息运行很好，但是如果我尝试运行 docker-compose，我会收到权限被拒绝的错误。

我link编辑了/usr/local/bin/docker-compose文件到gitlab运行ner容器中，在运行nerconfig.toml文件的volumes参数中输入.

如果我尝试运行 sudo 它以未知命令错误结束，所以这不是解决方案。

我是否需要 link 一些文件或太多的嵌套容器？

Answer 1

如果你正在使用 dind，这意味着 docker 工作正常，现在你只需要安装 docker-compose 这只是简单的 python 包，你可以在before_script

.gitlab-ci.yml

image: docker:latest

services:
  - docker:dind

variables:
  DOCKER_DRIVER: overlay2

stages:
- test

before_script:
  - apk add --no-cache py-pip
  - pip install docker-compose
  - docker info
  - docker login -u gitlab-ci-token -p $CI_JOB_TOKEN docker.registry.com

test:
  stage: test
  script:

    - cp .env.sample .env # copy environement variable
    - docker-compose up -d
    # run some test here

Answer 2

为了拥有 docker-compose，您需要为图像 docker 安装它，它的版本为 18.09.6，在撰写本文时构建 481bc77。

因为 docker-compose version 1.24.0, you also need the following dependencies for docker-compose to be installed on alpine:

apk add py-pip python3-dev libffi-dev openssl-dev gcc libc-dev make

这是一个示例 .gitlab-ci.yml:

image: docker:stable

stages:
    - deploy

services:
  - docker:dind

before_script:
  - apk update
  - apk add py-pip python3-dev libffi-dev openssl-dev gcc libc-dev make
  - pip install docker-compose

deploy_app:
    stage: deploy
    script:
        - docker-compose down
        - docker-compose up -d

Answer 3

运行 docker-compose inside docker in docker 的最佳选择是使用 docker/compose 图像，如下所示：

job-x:
  image: docker/compose
  script:
    - docker-compose version

一个真实而完整的例子是使用 docker-compose 在服务器上部署特定安装的运行器，如下所示：

image: docker:stable

services:
  - docker:dind

stages:
  - build
  - deploy

before_script:
  # resolve TAG
  # Default branch leaves tag latest
  # All other branches are tagged with the escaped branch name (commit ref slug)
  - |
    if [[ "$CI_COMMIT_BRANCH" == "$CI_DEFAULT_BRANCH" ]]; then
      TAG="latest"
      echo "Running on default branch '$CI_DEFAULT_BRANCH': tag = '$TAG'"
    else
      TAG="$CI_COMMIT_REF_SLUG"
      echo "Running on branch '$CI_COMMIT_BRANCH': tag = $TAG"
    fi
  

docker-build:
  stage: build
  script:
    - echo "user ${CI_REGISTRY_USER}"
    - echo "registry ${CI_REGISTRY}"
    - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
    - docker build --build-arg BUILDKIT_INLINE_CACHE=1 --cache-from "$CI_REGISTRY_IMAGE:${TAG}" -t "$CI_REGISTRY_IMAGE:${TAG}" .
    - docker push "$CI_REGISTRY_IMAGE:${TAG}"
  when: manual

deploy-staging:
  image: docker/compose
  stage: deploy
  variables:
    IMAGE: $CI_REGISTRY_IMAGE
    TAG: $TAG
    HOST_PORT: $HOST_PORT
  script:
    - docker-compose version
    - docker-compose -f docker-compose.yml up -d --no-build
  when: manual

docker-compose.yml 文件看起来像：

version: "3.7"

services:
  web:
    image: $IMAGE:$TAG
    build:
      context: .
    ports:
      - $HOST_PORT:8000
