Detailed explanation of using docker to deploy GitLab CE Chinese version application on CentOS 7

1. Pulling images in China is relatively slow, so the DaoCloud source is used here.

# curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://43049fd0.m.daocloud.io

2. Pull the image

# docker pull twang2218/gitlab-ce-zh

3. Start the container

docker run --detach \
--hostname git.xiaohuruwei.com \
--publish 8443:443 --publish 8080:80 --publish 2222:22 \
--name gitlab \
--restart always \
--volume /srv/gitlab/config:/etc/gitlab \
--volume /srv/gitlab/gitlab/logs:/var/log/gitlab \
--volume /srv/gitlab/gitlab/data:/var/opt/gitlab \
twang2218/gitlab-ce-zh:latest

4. Explanation of command parameters

--hostname
指定容器中绑定的域名，会在创建镜像仓库的时候使用到，这里绑定git.xiaohuruwei.com
 
--publish
端口映射，冒号前面是宿主机端口，后面是容器expose出的端口
 
--volume
volume 映射，冒号前面是宿主机的一个文件路径，后面是容器中的文件路径

5. Local access address

git.xiaohuruwei.com

Note: When you open it for the first time, you need to set a password. The default username is root.

ssh access

Because it is deployed using docker, access through ssh (such as git clone git@git.xiaohuruwei.com) will have two layers of authentication:

The first layer is the certification of the freelancer server

The other layer is gitlab certification.

The latter requires the use of ssh-key

The former may require the reverse proxy of ssh itself (the nginx currently used does not support reverse proxies other than http and https),

Now I find it difficult to use port forwarding, but you can change the default gitlab ssh port to a non-standard port:

Directly modify the variables in the gitlab configuration file:

gitlab_shell_ssh_port = 2222

Then restart the docker container, you can see the corresponding ssh address has changed in the web interface: ssh://git@git.xiaohuruwei.com:2222/root/test.git Then you can continue to use it directly git clone to continue the operation
