gitlab-CICD共享runner基本配置

使用docker部署runner
多个项目使用共享runner
部署机器与runner不在同一台服务器上（使用ssh部署）

部署runner

部署镜像

docker pull gitlab/gitlab-runner:latestdocker run -d --name gitlab-runner-shared \ --restart always \ -v /var/run/docker.sock:/var/run/docker.sock \ gitlab/gitlab-runner:latest

注册runner

docker exec -it gitlab-runner-shared gitlab-runner \ register -n \ --tag-list "gitlab-runner-shared" \ --description "描述" \ --url <私有gitlab地址> \ --registration-token <项目/共享token> \ --executor docker \ --docker-privileged \ --docker-image "alpine:latest" \ --docker-pull-policy "if-not-present" \ --docker-volumes "/var/run/docker.sock:/var/run/docker.sock"

SSH相关配置

【gitlab-CICD共享runner基本配置】在linux服务器使用ssh-keygen创建一个ssh key

ssh-keygen -t rsa -P "" ~/.ssh/id_rsa
推送到部署服务器上

ssh-copy-id -i ~/.ssh/id_rsa.pub <远程服务器ip>
测试登录

ssh <远程服务器登录名>@<远程服务器ip> # 按提示输入密码

将私钥复制下来

cat ~/.ssh/id_rsa
将私钥设置到Gitlab的变量中（例如：SSH_PRIVATE_KEY）
远程部署（编写ci文件）

image_build: stage: build image: alpine:latest before_script: - sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories # 设置国内镜像源 - 'which ssh-agent || ( apk update && apk add openssh-client )' # 安装ssh - eval $(ssh-agent -s) - echo "$SSH_PRIVATE_KEY" > deploy.key # 设置ssh私钥 - chmod 0600 deploy.key # 设置私钥权限 - ssh-add deploy.key # 添加到缓存中 - mkdir -p ~/.ssh - '[[ -f /.dockerenv ]] && echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config' # 第一次登录不需要询问 script: - ssh <用户名>@<服务器ip> "ls && exit" # 远程执行语句

使用docker打包

image-build: stage: build image: docker:18.09.7 services: - docker:18.09.7-dind script: - docker build --no-cache -t <镜像>:<镜像tag> . # 生成镜像 - docker login -u -p # 登录云端 - docker push <镜像>:<镜像tag> # 镜像推送到云端 after_script: - docker rmi -f <镜像>:<镜像tag> # 已上传云端，清理本地镜像，减少占用内存 retry: max: 2 when: always

通知（curl）

build-job-failure: stage: build-notify when: on_failure# 失败时通知 image: alpine:latest before_script: - sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories # 设置国内镜像源 - apk update && apk add curl # 安装curl script: - if [ "$CI_COMMIT_REF_NAME" == "dev" ]; then env_name="dev"; else env_name="prod"; fi - echo '{"content":"@'$GITLAB_USER_LOGIN' '${CI_COMMIT_TITLE}'\n'$CI_PROJECT_NAME' 构建'$env_name'环境 [ 失败 ]"}' > content.json # 避免提交文字中有空格导致报错，使用json的方式 - curl -X POST -H "Content-Type:application/json" -d @content.json "$NOTIFY_URL"
