How to use docker to build a gitlab server in Centos7? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

Install and start docker

Installation: yum-y install docker

Launch: systemctl start docker

Boot: systemctl enable docker

Second, pull the image file

Docker images # check the image file. There is no image before pulling it.

Docker search gitlab # search for images

The first image will be downloaded in this article.

Docker pull docker.io/gitlab/gitlab-ce # download image, after the download is completed

Docker images # View image file

Run the gitlab container

The copy code is as follows:

Docker run-- name='gitlab-ce'-d-p 10022 restart always-- volume / opt/gitlab/config:/etc/gitlab-- volume / opt/gitlab/logs:/var/log/gitlab-- volume / opt/gitlab/data:/var/opt/gitlab/ gitlab/gitlab-ce 80:80

Note:

-- name= "nginx-lb": specify a name for the container

-d: runs the container in the background and returns the container ID

-p: specify the mapped port number. In this article, port 22 of ssh is mapped to port 10022, and port 80 accessed by web is mapped to port 80

-volume: used to specify the mount directory and mount the config configuration directory, data data directory and logs log directory to the host for convenient backup in the future.

Finally, there is the name of the downloaded container.

This allows you to run a gitlab server through the docker container.

Docker ps # View the running container

Docker stop name or ID # close the container

Docker start name or ID number # Open the container

Docker rmiID # Delete the container

Configure the access address and mailbox of the gitlab server

When the gitlab server is running, a configuration file gitlab.rb is generated in the mapping directory / opt/gitlab/config/ directory

Edit the gitlab.rb file

Vim / opt/gitlab/config/gitlab.rb# configure the access address used by the http protocol external_url 'http://172.16.81.81'# configure the access address and port gitlab_rails used by the ssh protocol [' gitlab_ssh_host'] = '172.16.81.81'gitlab_rails [' gitlab_shell_ssh_port'] = 10022

Configure Mail

Vim / opt/gitlab/config/gitlab.rb# take Sina's mailbox as an example to configure the smtp server gitlab_rails ['smtp_enable'] = truegitlab_rails [' smtp_address'] = "smtp.xxx.com" gitlab_rails ['smtp_port'] = 25gitlab_rails [' smtp_user_name'] = "name4mail" gitlab_rails ['smtp_password'] = "passwd4mail" gitlab_rails [' smtp_domain'] = "xxx.com" gitlab_rails [' Smtp_authentication'] =: logingitlab_rails ['smtp_enable_starttls_auto'] = true# another thing to note is to specify the mailbox to use to send the mail. This should be consistent with the mailbox configured above gitlab_rails ['gitlab_email_from'] =' name4mail@xxx.com'

Set up the network IP

# set the network IPpipework br0 gitlab-ce 172.16.81.81Universe 172.16.81.1

After modifying the gitlab.rb configuration file, restart the container.

# enter the container docker exec-it gitlab-ce bash# to restart gitlabgitlab-ctl reconfigure

The access address generated by the project on gitlab is as follows

# HTTP http://172.16.81.81/root/test-docker-gitlab.git # SSH ssh://git@172.16.81.81:10022/root/test-docker-gitlab.git

5. Web access verification

The initial page is to set the password, and the setting is what you saw at the beginning.

Initial user name: root
