云计算-容器云-部署CICD-Runners-demo2048

1、部署GitLab(3分)
​ 将GitLab部署到Kubernetes集群中，设置GitLab服务root用户的密码，使用Service暴露服务，并将提供的项目包导入到GitLab中。

​ 在Kubernetes集群中新建命名空间gitlab-ci，将GitLab部署到该命名空间下，Deployment和Service名称均为gitlab，以NodePort方式将80端口对外暴露为30880，设置GitLab服务root用户的密码为admin@123，将项目包demo-2048.tar.gz导入到GitLab中并命名为demo-2048。(需要用到的软件包：CICD-Runners-demo2048.tar.gz)

登录后复制

# 上传解压文件
tar -zxvf Gitlab-CI.tar.gz

# 导入镜像
ctr -n k8s.io image import gitlab-ci/images/images.tar

# 新建空间
kubectl create ns gitlab-ci

# 进入命名空间
