Environment background:
Docker technology has become a popular, recording about the use of docker engine installation gitlab.
test environment:
| system | software | rely |
| CentOS 7.4 | GitLab（latest） | docker is 18 |
Installation process:
1. Install and start the engine docker
[root @ server-10 ~] # yum install docker-ce -y // need to go to the official docker.repo file [root @ Server-10 ~] # systemctl enable Docker [root @ Server-10 ~] # systemctl Start Docker
2. Get image packages gitlab
[Root @ server-10 ~] # docker pull gitlab / gitlab-ce // something more integrated inside mirror may be relatively large
View downloaded image
[root@server-10 logs]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE gitlab/gitlab-ce latest 991cd608c116 2 weeks ago 1.59GB
3. Prepare the working directory on the local gitlab
[root@server-10 ~]# mkdir -p /data/docker/gitlab/{config,data,logs}
In the above the machine is set up three directories can be mapped to gitlab container configuration file after startup mount the local directory, the data files, log files to the machine, and then can view and edit follow directly in the machine, and no longer operation into the container.
4. gitlab start (critical step)
Description:
-d : background
--name : Set the vessel's name;
--hostname : Setting the host name of the vessel;
--restart : Set a container restart policy options: no | on-failure [: max-retries] | always | unless-stopped;
-p (lowercase letters): port mapping, form: [hostPort:] containerPort, if not the host port, random port will be generated on the host;
-v (lower case letters): mounted directories form: [HOST-DIR:] CONTAINER -DIR;
4. Check the startup information
[root@server-10 ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3c8cdd184582 gitlab/gitlab-ce:latest "/assets/wrapper" About a minute ago Up About a minute (health: starting) 0.0.0.0:2222->22/tcp, 0.0.0.0:8888->80/tcp, 0.0.0.0:4443->443/tcp gitlab
It takes some time to start, after a period of time to see again
[root@server-10 logs]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3c8cdd184582 gitlab/gitlab-ce:latest "/assets/wrapper" 3 minutes ago Up 3 minutes (healthy) 0.0.0.0:2222->22/tcp, 0.0.0.0:8888->80/tcp, 0.0.0.0:4443->443/tcp gitlab
View local port status
[root@server-10 ~]# netstat -tnl Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN tcp6 0 0 :::2222 :::* LISTEN tcp6 0 0 :::22 :::* LISTEN tcp6 0 0 :::8888 :::* LISTEN tcp6 0 0 :::4443 :::* LISTEN

As can be seen above integrated inside or with a lot of things.
5. Log gitlab
Enter the installation gitlab container in the browser host address, in the form of IP: PORT
First login set a new password, and then log on to the next screen, the user name: root , Password: < Previous set password >
Later you can use.
6. Troubleshooting
If the initial login browser 502 check to see if a port conflict, modify the file gitlab.rb port-related items Unicorn [ 'Port'] = PORT ;
Can also be based logs directory information tracking and tracing, if GitLab external URL must include a schema and FQDN , please try to modify the configuration item format external_url gitlab.rb files = 'gitlab.xxx.com' or external_url ' HTTP: / / 138.138.82.10 '.
7. Update GitLab
If the above method to install, update, change is simple: stop gitlab container, remove the stop gitlab container, get a new image, use the original start command to start a new gitlab container again. Do not worry about data loss, as long as consistent with previous mount directory, it will automatically read the data in the original directory host.
Attached commonly used command gitlab
gitlab-ctl reconfigure // reapply gitlab configuration
gitlab-ctl restart // restart gitlab service
gitlab-ctl status // View gitlab running state
gitlab-ctl stop // stop gitlab service
gitlab-ctl tail // Check gitlab Run Log
End.
