Gitlab-ci + DinD + Mysql服务权限问题

Question

我创建了两个gitlab作业:

• 测试单元(在gitlab上使用php注册的docker)
• 声纳(使用docker服务运行"Letsdeal/docker-sonar-scanner")

我使用以下gitlab-ci-multi-runner配置:

concurrent = 1
check_interval = 0

[[runners]]
  name = "name-ci"
  url = "https://uri/ci"
  token = "token"
  executor = "docker"
  [runners.docker]
    tls_verify = false
    image = "docker:latest"
    privileged = true
    disable_cache = false
    volumes = ["/cache"]
    shm_size = 0
  [runners.cache]

测试单元作业正常工作但Sonar作业对以下消息失败:

service runner-f66e3b66-project-227-concurrent-0-docker-wait-for-service did timeout

2017-07-05T16:13:18.543802416Z mount: mounting none on /sys/kernel/security failed: Permission denied
2017-07-05T16:13:18.543846406Z Could not mount /sys/kernel/security.
2017-07-05T16:13:18.543855189Z AppArmor detection and --privileged mode might break.
2017-07-05T16:13:18.543861712Z mount: mounting none on /tmp failed: Permission denied

当我将'runner.docker'的配置参数'privileged'更改为false时.声纳工作但测试单元失败:

service runner-f66e3b66-project-227-concurrent-0-mysql-wait-for-service did timeout

2017-07-05T15:08:49.178114891Z 
2017-07-05T15:08:49.178257497Z ERROR: mysqld failed while attempting to check config
2017-07-05T15:08:49.178266378Z command was: "mysqld --verbose --help"
2017-07-05T15:08:49.178271850Z 
2017-07-05T15:08:49.178276837Z mysqld: error while loading shared libraries: libpthread.so.0: cannot open shared object file: Permission denied

"特权"的参数必须是真实的才能在docker中使用docker.但是我不明白为什么它会为像MySQL这样的服务打破许可.

这是我的gitlab-ci文件:

stage :
  - test-unit
  - analyse

.php_job_template: &php_job_template
  image: custom_docker_image
  before_script:
    - eval $(ssh-agent -s) && ssh-add <(echo "$SSH_PRIVATE_KEY")
    - mkdir -p ~/.ssh && echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config
  services :
    - mysql
  variables:
    MYSQL_DATABASE: blabla
    MYSQL_USER: blabla
    MYSQL_PASSWORD: blabla
    MYSQL_ROOT_PASSWORD: blabla

test_phpunit_dev:
  <<: *php_job_template
  stage: test-unit
  script:
    - mysql -h mysql -u blabla -pblabla <<< "SET GLOBAL sql_mode = '';"
    - php composer.phar install -q
    - php vendor/bin/phpunit -c tests/phpunit.xml

sonar:
  stage: analyse
  image: docker:1.12.6
  services:
    - docker:dind
  script:
    - docker run --rm -v `pwd`:/build -w /build letsdeal/sonar-scanner:2.7 scan -e

如果有人知道该解决谁,欢迎你.谢谢.

我遇到了同样的问题，并且能够通过删除 MySQL （因为我在 CI 服务器上不需要它）并禁用AppArmor来解决它。在 Ubuntu 上，您可以运行：

# Remove Mysql
sudo apt-get remove mysql-server

# Disable AppArmor for MySQL
sudo ln -s /etc/apparmor.d/usr.sbin.mysqld /etc/apparmor.d/disable/
sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.mysqld
