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
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:
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:
#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:
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
vim /etc/hosts 127.0.0.1 docker.registry.com
安装Nginx
apt-get install nginx #配置Nginx config vim /etc/nginx/nginx.conf
user www-data; worker_processes 4; pid /run/nginx.pid; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; # server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "msie6"; # gzip_vary on; # gzip_proxied any; # gzip_comp_level 6; # gzip_buffers 16 8k; # gzip_http_version 1.1; # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; ## # nginx-naxsi config ## # Uncomment it if you installed nginx-naxsi ## #include /etc/nginx/naxsi_core.rules; ## # nginx-passenger config ## # Uncomment it if you installed nginx-passenger ## #passenger_root /usr; #passenger_ruby /usr/bin/ruby; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; upstream docker-registry { server localhost:5000; } server { listen 80; server_name docker.registry.com; proxy_set_header Host $http_host; # required for docker client's sake proxy_set_header X-Real-IP $remote_addr; # pass on real client's IP client_max_body_size 0; # disable any limits to avoid HTTP 413 for large image uploads # required to avoid HTTP 411: see Issue #1486 (https://github.com/dotcloud/docker/issues/1486) chunked_transfer_encoding on; # location / { proxy_pass http://docker-registry; } } }
启动Nginx
service nginx start
访问浏览器测试
http://192.168.124.130/
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
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
[program:docker-registry] directory=/opt/docker-registry #使用docker用户 user=docker command=/usr/local/bin/gunicorn --access-logfile - --error-logfile - -k gevent -b 0.0.0.0:5000 -w 8 --max-requests 100 --graceful-timeout 3600 -t 3600 docker_registry.wsgi:application redirect_stderr=true stderr_logfile=none stdout_logfile=/var/log/supervisor/docker-registry.log autostart=true autorestart=true
#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}
