如何在本地搭建Docker-Registry

獲取Docker-Registry

docker pull registry:0.6.7

配置Docker-Registry

mkdir /datadisk/data/registry
mkdir /datadisk/data/registry/conf
mkdir /datadisk/data/registry/data

vim  /datadisk/data/registry/conf/config.yml

config.yml:

common:
    loglevel: info
    secret_key: _env:SECRET_KEY
dev:
    storage: local
    storage_path: /registry-data

啓動Docker-Registry

REGISTRY=$(docker run -d -i -t --dns x.x.x.x --expose 80 -v /datadisk/data/registry/conf:/registry-conf -v /datadisk/data/registry/data:/registry-data -e REGISTRY_PORT=80 -e DOCKER_REGISTRY_CONFIG=/registry-conf/config.yml -e SETTINGS_FLAVOR=dev registry)

請將DNS換成您自己的DNS服務器

此處只所以要使用私有DNS的原因是因爲我們希望用簡短的域名訪問這個服務，比如repos.rd,但是這個域名又不存在，所以我們需要這個私有DNS服務器做解析，當然如果我們的域名是公有的，或直接使用IP，則不需要設置，否則會出現http://repos.rd/v1/_ping: i/o timeout

獲取這個Container的IP

docker inspect -format '{{ .NetworkSettings.IPAddress }}' $REGISTRY

配置NGINX

sudo vim /etc/nginx/sites-enabled/docker-registr.conf

請確保/etc/nginx/nginx.conf有include /etc/nginx/sites-enabled/*.conf這條語句

upstream docker-registry {
  server 172.30.0.4:80; # docker-registry
}

server {
  listen 80;
  server_name repos.rd; # private local netework name


  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
  #proxy_set_header Authorization  "";

  client_max_body_size 0; # disable any limits to avoid HTTP 413 for large image uploads

  location / {
    proxy_pass http://docker-registry;
  }
}

重啓 NGINX

sudo service nginx restart
