docker安装部署gitlab[完全自主版]

GitLab是由GitLabInc.开发，使用MIT许可证的基于网络的Git仓库管理工具，且具有wiki和issue跟踪功能。使用Git作为代码管理工具，并在此基础上搭建起来的web服务。时常别企业用作代码存储仓库。文章使用docker中运行操作系统的方式完成部署软件，不使用已有的gitlab-ce镜像。文章约定琥珀字体命令为容器中执行命令，黑色字体为宿主机执行命令，红色字体为需替换参数，青蓝色为命令输出或配置文件内容。

实施步骤

步骤概述：

1. 定制操作系统镜像
2. 部署软件
3. 配置gitlab

一、定制镜像

容器ubuntu 18、20镜像默认没有安装systemd服务，会导致容器赋予操作系统特权时报错失败，需要手动安装systemd服务。同时部署一些常用的软件及工具。

宿主机中执行

# docker run -idt  --name define_ubuntu 54919e10a95d
# docker exec -it define_ubuntu  /bin/bash


以下命令容器中执行，容器中安装软件

# apt clean all 
# apt-get update
# apt-get install libsemanage1 libsemanage1-dev  -y
# apt-get install wget sudo  systemd openssh-server vim net-tools tzdata -y
# exit


生成镜像

# docker commit -p  define_ubuntu

宿主机中执行，为新生成的镜像打标签,通过查到的镜像id号打标

# docker images  
# docker tag  image_id    ubuntu:18.04_2
# docker images


删除容器，一定要确认自定义镜像能够正常运行再删除。

# docker rm -f define_ubuntu

二、部署软件

基于第一步制作的镜像，运行一个具有操作特权的容器，在容器中进行gitlab软件安装配置,由于在运行容器的时候使用 –privileged=true 参数后期会出现agetty进程占用过高的CPU，所以需要执行systemctl stop getty@tty1.service和 systemctl disable getty@tty1.service命令关闭agetty进程。

2.1 安装软件

# docker run -idt --privileged=true -p 8866:8866  --name ubuntu_gitlab  ubuntu:18.04_2  /sbin/init
# docker exec -it ubuntu_gitlab  /bin/bash

# systemctl stop getty@tty1.service
# systemctl disable getty@tty1.service
# cd 
# wget  https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/ubuntu/pool/xenial/main/g/gitlab-ce/gitlab-ce_11.11.8-ce.0_amd64.deb
# ls -l
# dpkg -i gitlab-ce_11.11.8-ce.0_amd64.deb

Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
  sudo gitlab-ctl reconfigure

For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md

2.2 配置软件

便捷/etc/gitlab/gitlab.rb配置文件,红字部分根据实际情况配置。配置文件可以直接复制然后按照实际情况修改。

# cp -rp /etc/gitlab/gitlab.rb  /root/gitlab.rb.bakcup
# vim /etc/gitlab/gitlab.rb
external_url 'http://192.168.111.136:8866'
#mail configure
gitlab_rails['gitlab_email_from'] = '302950208@qq.com'
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.qq.com"
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = "302950208@qq.com"
gitlab_rails['smtp_password'] = "adhxxxblssssffblbcafe"
gitlab_rails['smtp_domain'] = "qq.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true
user['git_user_name'] = "302950208@qq.com"

执行命令配置软件

# nohup sudo /opt/gitlab/embedded/bin/runsvdir-start &
# sudo gitlab-ctl   reconfigure 
..................
