Docker  Registry 私有仓库搭建

官方已经提供了很多版本的 Linux 镜像,直接从官方仓库(Public Repositories)下载就可以了。如果考虑到安全性和速度,我们可能会想在自己局域网里架设一个私有仓库(Private Repositories)来放我们自己的镜像,Docker-Registry 正是我们需要的工具。

本次搭建

docker-registry server (dev) (v0.9.0)

添加docker用户和目录

为了安全起见,我们可以添加一个用户docker,使用这个非root用户来允许docker registry程序,同时指定好docker镜像的存储位置,本处指定为/home/docker_registry目录

?
1
2
3
useradd docker
mkdir -p /home/docker_registry
chown -R docker.docker /home/docker_registry/

 从github克隆最新版本registry, 进入这个目录下的config子目录,从模板复制一个配置文件出来:

?
1
2
3
git clone https://github.com/docker/docker-registry.git
cd docker-registry/config
cp config_sample.yml config.yml

此时可以修改这个config.yml配置文件,需要注意修改以下的两个地方:

?

6
#配置sqlite数据库位置
sqlalchemy_index_database: _env:SQLALCHEMY_INDEX_DATABASE:sqlite:////home/docker_registry/docker-registry.db
#配置本地存储位置
local: &local
  storage: local
  storage_path: _env:STORAGE_PATH:/home/docker_registry

安装一些必要软件包和一些 Docker-Registry 需要用到的 Python 工具和库:

?
1
2
apt-get update
apt-get install build-essential python-dev liblzma-dev libevent-dev python-pip libssl-dev

使用apt-get安装软件包时经常会提示让你插入netinst的光盘:

Media change: please insert the disc labeled

当没有时就无法进行安装了, 这时可以打开文件/etc/apt/sources.list文件,注释掉cdrom那一行,

然后再执行apt-get update更新下deb仓库,

这样以后再使用apt-get安装时就不会再搜寻cdrom了

修改HOSTS文件加上域名

?
1
2
vim /etc/hosts
127.0.0.1 docker.registry.com

安装Nginx

?
1
2
3
apt-get install nginx
#配置Nginx config
vim /etc/nginx/nginx.conf

启动Nginx

service nginx start

访问浏览器测试

安装python依赖

?

cd /opt/docker-registry
pip install .

若出现:Cannot connect to proxy. Socket error: [Errno -2] Name or service not known.

手动安装依赖包 加代理参数

?

3
pip install -i http://pypi.v2ex.com/simple .
#注销下面的 pip install . 安装全部
--pip install -i http://pypi.v2ex.com/simple gunicorn

建立软连接

ln -s /usr/local/bin/gunicorn /usr/bin/gunicorn

nginx启动之后,使用docker用户执行以下的命令可以测试启动:

gunicorn --access-logfile - --error-logfile - -k gevent -b 0.0.0.0:5000 -w 8 --max-requests 100 docker_registry.wsgi:application
访问浏览器

http://docker.registry.com

如果看到以下的输出,则表明docker registry安装成功

给目录下数据库赋权限,不然上传文件时会不能写数据库

chmod 777 /home/docker_registry/repositories/docker-registry.db

使用supervisord来进行进程的监控

apt-get install supervisor

配置supervisor [docker-registry]

vim /etc/supervisor/conf.d/docker-registry.conf

#重新加载 supervisor 配置:
supervisorctl
supervisor> reread
docker-registry: available
supervisor> update
docker-registry: added process group
supervisor> status
docker-registry  RUNNING  pid 4371, uptime 0:00:01

查看端口占用

netstat -apn | grep 5000

启动重启

service supervisor start
#/etc/init.d/supervisord {start|stop|restart|force-reload|status|force-stop}
