這是阿里內網的一篇文章，感有用，故轉載來了，自己實際搭建了，故記錄一下：

背景
在日常工作中，我們往往會搭建基于jenkins的集成測試環境來保證每次代碼功能的正確性，相關jenkins插件也非常豐富，比較適合復雜的集成環境。jenkins雖好，但需要投入人力維護，那有沒有一種比較輕量級別的集成工具，答案是肯定的。GitLab自從8.0版本之后，自動集成GitLab-CI功能。那接下來讓我們窺探下docker+GitLab-CI結合的集成環境。
GitLab 開啟build功能
GitLab項目-》項目設置-》勾選builds選項-》保存。開啟后會發現多了幾個菜單，打開setting，選擇runner，提示Runner安裝指令。其中Runner有兩種模式：Specific runners 和 Shared runners，如下圖：

runners

基于docker的GitLab-Muti-Runner安裝、啟動&注冊
準備工作
準備一臺已裝有Docker engine的ECS機器，由于alidocker不支持CMD，顧以下均原生docker以及Specific Runners為示例進行說明。
安裝&啟動
docker run -d --name gitlab-runner --restart always \ -v /var/run/docker.sock:/var/run/docker.sock \ -v /home/fanzhong/gitlab-runner/config:/etc/gitlab-runner \ gitlab/gitlab-runner:latest

腳本說明：
/var/run/docker.sock:/var/run/docker.sock：后續docker相關操作有關，務必配置
/home/fanzhong/gitlab-runner/config:/etc/gitlab-runner：mount此文件，方便配置gitlab-runner相關配置以及資源等，建議配置；

注冊Runner至GitLab
注冊的過程，實際是將Runner與GitLab web端關聯起來，其注冊過程如下：

docker exec -it gitlab-runner gitlab-ci-multi-runner registerRunning in system-mode. Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/ci):http://gitlab.alibaba-inc.com/ciPlease enter the gitlab-ci token for this runner:xxxxxxxxxxxxxPlease enter the gitlab-ci description for this runner:Please enter the gitlab-ci tags for this runner (comma separated):dockerRegistering runner... succeeded runner=270fa832Please enter the executor: docker-ssh, parallels, shell, ssh, virtualbox, docker+machine, docker-ssh+machine, docker:dockerPlease enter the default Docker image (eg. ruby:2.1):reg.docker.alibaba-inc.com/aliexpress/spring-boot-start-scripts-ci:no-nginxRunner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!

其中的Coordinator URL 和 token來自GitLab。最終GitLab-Runner生成的相關配置config.toml內容如下:
concurrent = 1check_interval = 0[[runners]] name = "spring-boot-scripts" url = "http://gitlab.alibaba-inc.com/ci" token = "xxxxx" executor = "docker" [runners.docker] tls_verify = false image="reg.docker.alibaba-inc.com/aliexpress/spring-boot-start-scripts-ci:no-nginx" privileged = false disable_cache = false volumes = ["/cache"] [runners.cache] Insecure = false

.gitlab-ci.yml
在項目根目錄下面添加yml配置文件，內容如下，更多配置信息詳見.gitlab-ci.yml：
image: reg.docker.alibaba-inc.com/aliexpress/spring-boot-start-scripts-ci:no-nginxbefore_script: - rsync -avz /tmp/builds/spring-boot/startup-scripts/template/bin/* /home/admin/spring-boot-demo-application/bin/ | sed 's/^/ /g' - sed -i "s/template/spring-boot-demo-application/g" /home/admin/spring-boot-demo-application/bin/setenv.sh - rsync -avz /tmp/builds/spring-boot/startup-scripts/cai/* /home/admin/cai/ - sed -i "s/@appName@/spring-boot-demo-application/g" /home/admin/cai/conf/* - chmod u+x /home/admin/spring-boot-demo-application/bin/* /home/admin/cai/bin/nginxctl - chown -R admin:admin /home/admin/*stages: - testjob_no_nginx: stage: test script: - sed -i "s/NGINX_SKIP=0/NGINX_SKIP=1/g" /home/admin/spring-boot-demo-application/bin/setenv.sh - sh /home/admin/start.sh#job_nginx:# stage: test# script:# - sh /home/admin/start.sh# - curl localhost/status.taobao

用戶鏡像spring-boot-start-scripts-ci:no-nginx
此鏡像必須支持CMD命令，否則yml中相關scripts不會運行，內部提供的幾個OS基礎鏡像無法正常運行(alidocker不支持CMD)，請基于docker官方鏡像構建。
