2.gitlab所需文件准备

.gitlab-ci.yml

stages:
  - build
  - deploy

build:
  stage: build
  script:
    - chmod a+x build-push.sh 
    - sh build-push.sh
deploy:
  image: roffe/kubectl
  stage: deploy
  script:
    - chmod a+x deploy.sh
    - sh deploy.sh

3.gitlab-runner配置文件修改和k8s-master权限授予

#gitlab-runner主机修改

vim /etc/gitlab-runner/config.toml

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

#k8s集群master设置

kubectl create clusterrolebinding serviceaccounts-cluster-admin   --clusterrole=cluster-admin   --group=system:serviceaccounts

4.gitlab-ci/cd工作流程

1.代码持续集成到gitlab

2.触发流水线自动部署，根据.gitlab-ci.yml定义内容工作

3.gitlab-runner接收到任务进行一系列工作

4.流程 代码集成---触发gitlab-ci/cd---gitlab-runner接收任务并工作---镜像编译---推送镜像至harbor---k8s替换镜像版本完成更新
