GitlabCI构建失败，docker.sock：写：断管

标签： docker gitlab-ci gitlab-ci-runner rancher

我正在尝试使用GitlabCI实现新的CI工作流程，但现在我无法理解这个问题。我跟着this doc，我选择了Docker套接字绑定方法。

一切都在同一台机器上运行，RancherOS：

$ uname -a

$ docker ps

运行跑步者容器的命令

$ docker run -d --name gitlab-runner --restart always \
-v ~/docker/gitlab-runner/config:/etc/gitlab-runner \
-v /var/run/docker.sock:/var/run/docker.sock \
gitlab/gitlab-runner:latest

Runner的配置

$ sudo cat ~/docker/gitlab-runner/config/config.toml 
concurrent = 1
check_interval = 0

[[runners]]
  name = "ITrancher, docker based runner 4"
  url = "https://git.xxx.com"
  token = "xxx"
  executor = "docker"
  [runners.docker]
    tls_verify = false
    image = "docker:latest"
    privileged = false
    disable_cache = false
    volumes = ["/var/run/docker.sock:/var/run/docker.sock", "/cache"]
  [runners.cache]
  [runners.kubernetes]
    host = ""
    cert_file = ""
    key_file = ""
    ca_file = ""
    image = ""
    namespace = ""
    privileged = false
    cpus = ""
    memory = ""
    service_cpus = ""
    service_memory = ""

这是我的.gitlab-ci.yml文件 

image: docker:latest
before_script:
- docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.xxx.com
stages:
- build
build:
  stage: build
  script:
  - docker build --pull -f Dockerfile-php -t registry.xxx.com/dev/kayako-php:latest .
  - docker push registry.xxx.com/dev/kayako-php:latest
  - docker build --pull -f Dockerfile-nginx -t registry.xxx.com/dev/kayako-nginx:latest .
  - docker push registry.xxx.com/dev/kayako-nginx:latest

这就是我在构建被挂钩时进入GitlabCI的原因

当我尝试在我的gitlab-runner容器中使用--debug标志本地运行构建时，这是输出。

但我的docker.sock绑定似乎没问题：

# echo -e "GET /containers/json HTTP/1.0\r\n" | nc -U /var/run/docker.sock
HTTP/1.0 200 OK
Content-Type: application/json
Server: Docker/1.10.3 (linux)
Date: Wed, 19 Oct 2016 10:22:58 GMT

[{json is ok}]

有人有想法吗？

这是 gitlab-ci-multi-runner 的最新版本的已知错误（从v1.5.0开始）。

您可以使用版本1.4.2，直到错误得到妥善修复。 以下是使用最新工作版本的docker run命令：

$ docker run -d --name gitlab-runner --restart always \
-v ~/docker/gitlab-runner/config:/etc/gitlab-runner \
-v /var/run/docker.sock:/var/run/docker.sock \
gitlab/gitlab-runner:v1.4.2

Gitlab CI Multi Runner存储库中已存在一个问题：https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/issues/1617

修改：请使用v1.4.2代替v1.4.3。 Docker Hub上错误地标记了v1.4.3：

$ docker run --rm -it gitlab/gitlab-runner:v1.4.3 -v
Version:      1.5.2
Git revision: 76fdacd
Git branch:   1-5-stable
GO version:   go1.6.3
Built:        Wed, 24 Aug 2016 13:35:10 +0000
OS/Arch:      linux/amd64

这个问题已经很老了，虽然最初的问题可能已经回答，并且使用建议的解决方法工作，但是它目前不适用于gitlab-runner的11.0.0版本。我能够上班了...

OS：rancheros 1.4.0 控制台：高山 码头工人：docker-17.12.1-ce && docker-18.03.1-ce

我照常安装转轮，然后注册。发现故障...然后编辑toml文件，并将privileged = false更改为privileged = true。

sudo vim /srv/gitlab-runner/config/config.toml docker stop gitlab-runner docker rm gitlab-runner docker run -d --privileged --name gitlab-runner --restart always -v /srv/gitlab-runner/config:/etc/gitlab-runner -v /var/run/docker.sock:/var/run/docker.sock gitlab/gitlab-runner:latest
