GitLab Installation and Port Configuration on a Kubernetes Master

Install the necessary utilities on the Kubernetes master:

yum install curl policycoreutils openssh-server openssh-clients postfix -y

Restart Postfix and configure it to listen on all interfaces: systemctl restart postfix Edit /etc/postfix/main.cf and replace inet_interfaces = localhost with inet_interfaces = all.

Add the GitLab CE repository by creating /etc/yum.repos.d/gitlab-ce.repo with the following content:

[gitlab-ce]
name=gitlab-ce
baseurl=http://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7
repo_gpgcheck=0
gpgcheck=0
enabled=1
gpgkey=https://packages.gitlab.com/gpg.key

Refresh the repository cache and install GitLab CE:

yum makecache

yum -y install gitlab-ce

If the default ports 80 and 8080 are already in use, modify GitLab’s port settings. Edit /etc/gitlab/gitlab.rb and change: #unicorn['port'] = 8080 to

unicorn['port'] = 8070

#nginx['listen_port'] = nil

to nginx['listen_port'] = 8090 Update the Unicorn configuration file /var/opt/gitlab/gitlab-rails/etc/unicorn.rb: #listen "127.0.0.1:8080", :tcp_nopush => true becomes listen "127.0.0.1:8070", :tcp_nopush => true Adjust the Nginx configuration /var/opt/gitlab/nginx/conf/gitlab-http.conf: #listen *:80; becomes listen *:8090; Apply all changes with the GitLab reconfiguration command (which may take some time): gitlab-ctl reconfigure Optionally increase memory and reload the configuration again using the same command.

Manage the GitLab service with the following commands: gitlab-ctl start – start the service gitlab-ctl stop – stop the service gitlab-ctl restart – restart the service gitlab-ctl status – view service status

Finally, access GitLab via the web interface at http://192.168.210.85/ , log in as root, and create a new project to complete the deployment.
