验证访问

客户端新增hosts记录 192.168.3.160 gitlab.local.com
账号默认：root
密码需要去容器里面的 这里路径查看cat /etc/gitlab/initial_root_password
root@k8s-master-01:~/gitlab# kubectl exec -it -n cicd   gitlab-6fb47c476-vb6wf -- bash
root@gitlab-6fb47c476-vb6wf:/# cat /etc/gitlab/initial_root_password
# WARNING: This value is valid only in the following conditions
#          1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails['initial_root_password']` setting in `gitlab.rb`, it was provided before database was seeded for the first time (usually, the first reconfigure run).
#          2. Password hasn't been changed manually, either via UI or via command line.
#
#          If the password shown here doesn't work, you must reset the admin password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.
