官方已經(jīng)提供了很多版本的 Linux 鏡像，直接從官方倉庫（Public Repositories）下載就可以了。如果考慮到安全性和速度，我們可能會想在自己局域網(wǎng)里架設(shè)一個私有倉庫（Private Repositories）來放我們自己的鏡像，Docker-Registry 正是我們需要的工具。

本次搭建

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

添加docker用戶和目錄

為了安全起見，我們可以添加一個用戶docker，使用這個非root用戶來允許docker registry程序，同時指定好docker鏡像的存儲位置，本處指定為/home/docker_registry目錄

useradd docker
mkdir -p /home/docker_registry
chown -R docker.docker /home/docker_registry/

從github克隆最新版本registry, 進入這個目錄下的config子目錄，從模板復制一個配置文件出來：

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

此時可以修改這個config.yml配置文件，需要注意修改以下的兩個地方：

#配置sqlite數(shù)據(jù)庫位置
sqlalchemy_index_database: _env:SQLALCHEMY_INDEX_DATABASE:sqlite:////home/docker_registry/docker-registry.db
#配置本地存儲位置
local: &local
  storage: local
  storage_path: _env:STORAGE_PATH:/home/docker_registry

安裝一些必要軟件包和一些 Docker-Registry 需要用到的 Python 工具和庫：

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

使用apt-get安裝軟件包時經(jīng)常會提示讓你插入netinst的光盤：

Media change: please insert the disc labeled

當沒有時就無法進行安裝了，這時可以打開文件/etc/apt/sources.list文件，注釋掉cdrom那一行，

然后再執(zhí)行apt-get update更新下deb倉庫，

這樣以后再使用apt-get安裝時就不會再搜尋cdrom了

修改HOSTS文件加上域名

vim /etc/hosts
127.0.0.1 docker.registry.com

安裝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;
   }
  }
}

啟動Nginx

service nginx start

訪問瀏覽器測試

http://192.168.124.130/

安裝python依賴

cd /opt/docker-registry
pip install .

若出現(xiàn)：Cannot connect to proxy. Socket error: [Errno -2] Name or service not known.

手動安裝依賴包加代理參數(shù)

pip install -i http://pypi.v2ex.com/simple .
#注銷下面的 pip install . 安裝全部
--pip install -i http://pypi.v2ex.com/simple gunicorn

建立軟連接

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

nginx啟動之后，使用docker用戶執(zhí)行以下的命令可以測試啟動：

gunicorn --access-logfile - --error-logfile - -k gevent -b 0.0.0.0:5000 -w 8 --max-requests 100 docker_registry.wsgi:application
訪問瀏覽器

http://docker.registry.com

如果看到以下的輸出，則表明docker registry安裝成功

給目錄下數(shù)據(jù)庫賦權(quán)限,不然上傳文件時會不能寫數(shù)據(jù)庫

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

使用supervisord來進行進程的監(jiān)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用戶
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

#重新加載 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

啟動重啟

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