Gitlab + 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注册的对接程序)
• 声纳(使用对接服务运行“Letsdeal/ docker扫描仪”)

我使用以下gitlab-ci-多运行程序配置：

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]

测试单元作业工作正常，但Sonar作业在下列消息中失败：

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“特权”更改为false时，Sonar作业可以工作，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

param“特权”必须是真实的，才能在码头上使用码头。但我不明白为什么MySQL这样的服务会被破坏。

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

我该怎么解决这个问题？

Answer 1

例如，为什么不使用ciricihq/gitlab-sonar-scanner呢？它不需要使用dind或特权模式

官方github储存库

Answer 2

我也遇到了同样的问题，并且能够通过删除MySQL (反正在CI服务器上不需要它)和禁用AppArmor来解决这个问题。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
