gitlab-runner Docker安裝

Docker gitlab-runner安裝方法，推薦安裝原生服務器的runner，並修改.gitlab.yml以簡化測服部署步驟

鏡像拉取

sudo docker pull gitlab/gitlab-runner:v1.10.7

容器啓動

添加 gitlab-runner container

sudo docker run -d
--net host \
 --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:v1.10.7

Runner註冊

sudo docker exec -it gitlab-runner gitlab-ci-multi-runner register

註冊Runner步驟

Please enter the gitlab-ci coordinator URL:
    http://gitlab.com/ci
Please enter the gitlab-ci token for this runner:
    38sUHxxStGXytDTyfxDg
Please enter the gitlab-ci description for this runner:
    dubbo-runner(IP)
Please enter the gitlab-ci tags for this runner (comma separated):
    dubbo
Whether to run untagged builds [true/false]:
    true
Please enter the executor: docker, parallels, shell, kubernetes, docker-ssh, ssh, virtualbox, docker+machine, docker-ssh+machine:

Please enter the default Docker image (e.g. ruby:2.1):

Runner啓用

gitlab -> project -> Runners

Maven依賴

docker image每次構建都是在獨立的container裏， maven的 .m2文件並不會被多次構建公用，這裏我們可以通過修改gitlab-runner的配置，將maven .m2目錄加到volumes中，並增加鏡像拉取規則（默認是從遠程拉取鏡像，這裏修改爲優先獲取本地鏡像，不存在時纔去遠程拉取鏡像）。

config.toml爲runner配置文件，路徑見容器啓動的掛載目錄

[runners.docker]
    tls_verify = false
    image = "maven:3.3.9-jdk-8"
    privileged = false
    disable_cache = false
    volumes = ["/cache", "/media/raid10/maven/.m2:/root/.m2"]
    pull_policy = "if-not-present"
