错误解决方法

1. ERROR: Job failed (system failure): prepare environment: exit status 1. Check https://docs.gitlab.com/runner/shells/index.html#shell-profile-loading for more information

   原因：Ubuntu 20.04版本在执行ci时会出现此错误，解决方法是删除工作目录下的.bash_logout文件

   # 查看gitlab-runner配置
   jack@k8smaster:~$ ps aux | grep gitlab-runner
   
   root      314163  0.2  0.3 143980 30740 ?        Ssl  08:06   0:01 /usr/bin/gitlab-runner run --working-directory /home/gitlab-runner --config /etc/gitlab-runner/config.toml --service gitlab-runner --user gitlab-runner

   # 删除.bash_logout
   jack@k8smaster:~$ sudo rm -r /home/gitlab-runner/.bash_logout
   

2. Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.24/auth: dial unix /var/run/docker.sock: connect: permission denied

   原因：gitlab-runner账号权限不足，不能访问/var/run/docker.sock。

   # 将gitlab-runner用户加入docker组
   [root@gitlab-runner ~]# usermod -aG docker gitlab-runner
   
   # 查看
   [root@gitlab-runner ~]# groups gitlab-runner 
   

3. 执行kubectl命令报错：The connection to the server localhost:8080 was refused - did you specify the right host or port?

   原因：gitlab-runner账号没有kubeadm配置文件。

   mkdir -p /home/gitlab-runner/.kube
   sudo cp -i /etc/kubernetes/admin.conf /home/gitlab-runner/.kube/config
   sudo chown 755 /home/gitlab-runner/.kube/config
   

4. 启用多分支报错：Error: Cannot perform an interactive login from a non TTY device

   原因：变量受到保护，而除master分支默认被保护之外，其他分支未设置保护，无法读取被保护的变量

   将分支添加到受保护的分支下面；
   设置->仓库->Protected branches,选择要保护的分支。
