K8S+GitLab-自动化分布式部署ASP.NET Core(一) 部署环境

推荐两种部署方式:
1.https://github.com/wise2c-devops/breeze   (可视化Kubernetes集群部署工具,注本篇的部署方式)
2.https://github.com/opsnull/follow-me-install-kubernetes-cluster  (手动部署)

docker-compose安装推荐

version: '3'
services:
  gitlab:
    image: 'twang2218/gitlab-ce-zh'
    container_name: gitlab
    restart: unless-stopped
    environment:
      TZ: 'Asia/Shanghai'
      GITLAB_OMNIBUS_CONFIG: |
        external_url 'http://gitlab.evan.com'
        gitlab_rails['time_zone'] = 'Asia/Shanghai'
        #以下为启用邮件相关设置,我用的是QQ邮箱
        gitlab_rails['smtp_enable'] = true
        gitlab_rails['smtp_address'] = 'smtp.qq.com'
        gitlab_rails['smtp_port'] = 465
        gitlab_rails['smtp_user_name'] = '你的邮箱@qq.com'
        gitlab_rails['smtp_password'] = '邮箱密码'
        gitlab_rails['smtp_domain'] = 'smtp.qq.com'
        gitlab_rails['smtp_authentication'] = 'plain'
        gitlab_rails['smtp_enable_starttls_auto'] = true
        gitlab_rails['smtp_tls'] = true
        gitlab_rails['gitlab_email_from'] = '你的邮箱@qq.com'
        user["git_user_email"] = '你的邮箱@qq.com'
        #修改sidekiq的数量，减少内存占用，默认为15，也可以不填
        sidekiq['concurrency'] = 10
        #使用外部redis所需设置，根据刚刚生成的redis设置修改
        gitlab_rails['redis_port'] = 6379
        gitlab_rails['redis_host'] = '127.0.0.1'
        gitlab_rails['redis_password'] = '123'
        gitlab_rails['redis_database'] = '2'
        #因为22端口被占用，修改映射的端口号时，同时修改在Gitlab项目中的ssh地址加上端口号
        gitlab_rails['gitlab_shell_ssh_port'] = 10022
    ports:
      - '10080:80'
      - '10443:443'
      - '10022:22'
    networks:
      - net_db
    volumes:
      - ./config:/etc/gitlab
      - gitlab-data:/var/opt/gitlab
      - ./logs:/var/log/gitlab
volumes:
  gitlab-data:
    external: true
networks:
  net_db:
    external: true

docker network create net_db
docker volume create gitlab-data
docker-compose up -d
docker-compose logs -f (查看部署状态)

修改gitlab.rb文件
 external_url 'http://你的gitlab地址:10080'
 nginx['listen_port'] =80
docker-compose restart 

部署成功后Git运行以下命令:

Git global setup（Git全局设置）:
git config --global user.name "xxx"
git config --global user.email "xxx.com"

  ssh-keygen -t rsa -C "xxx@qq.com" -b 4096

 cat ~/.ssh/id_rsa.pub
 ssh -T -p 10022 git@localhost  (修改成你的地址,测试是否连接成功)
 打印: Welcome to GitLab, @xxx!  说明成功了

如果官方的Runner下载不了下载下面的

Gitlab-Runner服务器上安装Git
yum install -y git

1.下载二进制文件
# Linux x86-64
 sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64
2.赋予它执行权限：
 sudo chmod +x /usr/local/bin/gitlab-runner
3.创建GitLab CI用户：
 sudo useradd --comment 'GitLab Runner' --create-home gitlab-runner --shell /bin/bash
4.将gitlab ci用户添加到docker运行用户的组里面
 sudo usermod -aG root gitlab-runner
 sudo usermod -aG docker gitlab-runner

5.安装并作为服务运行：
sudo gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner 
 sudo gitlab-runner start
6.注册Gitlab-Runner ,shell 方式 
sudo gitlab-runner register
  官网参考链接:https://docs.gitlab.com/runner/register/index.html
7.测试
 sudo -u gitlab-runner -H docker info
8.给Gitlab-Runner 执行kubectl权限,拷贝 /root/.kube 文件夹 到 gitlab-runner 用户家目录下，且修改此文件夹属于 gitlab-runner用户和组
chown -R gitlab-runner.gitlab-runner .kube
sudo -u gitlab-runner kubectl get cs

sudo rpm -Uvh https://packages.microsoft.com/config/rhel/7/packages-microsoft-prod.rpm

sudo yum update

sudo yum install dotnet-sdk-2.2
