1、GitLab类似github，是个私有仓库

1、GitLab安装，至少8G内存4核cpu

# 查找Gitlab镜像
docker search gitlab/gitlab-ce
# gitlab镜像拉取
docker pull gitlab/gitlab-ce
# 查看镜像
docker images
# 本机先建3个目录，为了gitlab容器通过挂载本机目录启动后可以映射到本机目录
# 配置文件
mkdir -p /home/gitlab/etc
# 数据文件
mkdir -p /home/gitlab/data
# 日志文件
mkdir -p /home/gitlab/logs
# 启动容器 mygitlab，如果不指定--hostname，默认使用的是容器id访问。
docker run --name mygitlab -d \
--hostname=10.1.1.118 \
-p 4443:443 -p 8888:80 -p 8022:22 \
-v /home/gitlab/etc:/etc/gitlab \
-v /home/gitlab/data:/var/opt/gitlab \
-v /home/gitlab/logs:/var/log/gitlab \
--privileged=true \
gitlab/gitlab-ce:latest
# 动态查看容器日志
docker logs -f mygitlab

# 配置http协议所使用的访问地址，不加端口默认为80
vim /home/gitlab/etc/gitlab.rb  加上下面这一行配置
external_url 'http://10.1.1.118'

/home/gitlab/data/gitlab-rails/etc/gitlab.yml，刚才启动容器指定的--hostname可在此配置文件查看

网页访问登入，http://10.1.1.118:8888

# 查看root用户默认密码
cat /home/gitlab/etc/initial_root_password
Password: Gsxzpjm/RwJgHlHIUJIOTFvfYnM19sC2VMPM7NTmCng=

登录成功后，修改密码

创建项目

直接像使用github一样，所有操作都一样。

# 本机需要安装git环境
yum install git -y
git --version

# 克隆项目
git config --global user.name "Administrator"
git config --global user.email "admin@example.com"
git config --global credential.helper store

# 注意点：需要配置端口8888
git clone http://10.1.1.118:8888/root/base-test.git
cd base-test
touch README.md
git add .
git commit -m "update"
git push -u origin master

设置免密提交
