docker - Gitlab CI 构建失败，docker.sock : write: broken pipe

标签 docker gitlab-ci gitlab-ci-runner rancher

我试图使用 GitlabCI 实现新的 CI 工作流程，但现在我无法理解这个问题。我关注了this doc我选择的是Docker套接字绑定(bind)方法。

一切都在同一台机器上运行，RancherOS:

$ uname -a

$ docker ps

运行器容器的运行命令

$ 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

运行者的配置

$ 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

这就是当构建 Hook 时我进入 GitlabCI 的内容

这是我尝试在 gitlab-runner 容器内使用 --debug 标志在本地运行构建时的输出。

但是我的 docker.sock 绑定(bind)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？

最佳答案

这是最新版本 gitlab-ci-multi-runner 的一个已知错误(从 v1.5.0 开始)。

您可以使用版本1.4.2，直到错误得到正确修复。 这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 存储库中已存在问题:https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/issues/1617

编辑:请使用v1.4.2而不是v1.4.3。 v1.4.3 在 Docker Hub 上被错误标记:

$ 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
