Gitlab CI/CD 之 gitlab-runner 用 Docker 方式如何顺利工作

前阵子,k8s 是搭建起来了.但是这玩意更新太快,3个月后, 以前的方法不好使了...又有新坑了...

干脆就只跑 Docker 吧....

我擦,Docker也跑不起来了...说

**docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.**







以前只要在 .gitlab-ci.yml 里面填写 标红的就可以了.但是现在不行,会报 

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?



services:
  - docker:dind

variables:

  DOCKER_DRIVER: overlay




build:

  stage: build

  script:

  - export DOCKER_HOST="tcp://localhost:2375"




build-master:

  stage: build

  script:
    - echo $CI_REGISTRY_PASSWORD |  docker login -u "$CI_REGISTRY_USER" $CI_REGISTRY --password-stdin
    - docker build .





(注意, $CI_REGISTRY 这些环境变量是要填写在 Gitlab web 环境变量中的)







研究后,要在 gitlab-run 的 文件中包含

    volumes = ["/cache", "/var/run/docker.sock:/var/run/docker.sock"]







sudo cat /etc/gitlab-runner/config.toml



concurrent = 1

check_interval = 0




[[runners]]

  name = "k8s"

  url = "https://x.net"

  token = "xxxxxxxxxx"

  executor = "docker"

  [runners.docker]

    tls_verify = false

    privileged = true

    disable_cache = false

    volumes = ["/cache", "/var/run/docker.sock:/var/run/docker.sock"]

    shm_size = 0

  [runners.cache]










这样就可以 build 你项目中的 Dockerfile 了~

























贴个完整的 .gitlab.yml 文件:




image: docker:git
services:
  - docker:dind
variables:
  DOCKER_DRIVER: overlay
  
before_script:

  - echo $CI_REGISTRY_PASSWORD |  docker login -u "$CI_REGISTRY_USER" $CI_REGISTRY --password-stdin

build-master:
  stage: build
  script:
    - docker build .
    

  only:
    - master

build:
  stage: build
  script:
    - docker build .
  except:
    - master
