Docker的Docker Hub是一个公有的Registry, 从Docker Hub上可以找到很多的官方或个人构建的Docker Image, 通常, 这些image能满足开发、测试的需求. 但是如果想构建的image只在控制范围内共享, 而不是开放环境, 那就得搭建自己的私有Docker Registry. Docker官方实现了docker-registy, 根据官方的说明可以搭建自己的Docker Registry, 官方有两种方式搭建Docker Registry, 一种是按传统的部署软件的方法安装Docker Registry, 详细可参考Matthew Fisher的博客, 另一种是通过官方构建的Docker image来搭建Docker Registry. 本文简单介绍如何通过官方Docker image搭建自己的私有Docker Registry.

第一步: 下载官方Registry Docker Image

docker pull registry:latest

第二步: 准备配置文件

创建配置文件

Docker Registry自带一个config_sample.yml配置文件, 通常将这个文件重命名为config.yml作为基本配置文件.

配置flavors

Docker Registry可以以几种flavors运行, 这使得Docker Registry可以运行在开发模式, 产线模式或者自定义的模式. 从配置文件config_sample.yml可知包括如下的一些flavors.
common: 作为其他flavors的基本配置.
local: 将数据存放在本地文件系统.
s3: 使用AWS S3存放数据.
dev: 使用local flavor作为基本配置.
test: 作为单元测试的flavor.
prod: 默认使用s3 flavor作为产线配置.
除此之外, 也可以使用OpenStack的swift, glance, glance-swift来存放数据, 还有key/value存储elliptics, 以及Google Cloud Storage GCE来存放数据. 除前所述的内置flavors, 也可以自定义flavor. 下面是一个简单config.yml配置文件:
common:
    loglevel: info
    search_backend: "_env:SEARCH_BACKEND:"sqlalchemy_index_database:"_env:SQLALCHEMY_INDEX_DATABASE:sqlite:////tmp/docker-registry.db"prod:
    loglevel: warn
    storage: s3
    s3_access_key: _env:AWS_S3_ACCESS_KEY
    s3_secret_key: _env:AWS_S3_SECRET_KEY
    s3_bucket: _env:AWS_S3_BUCKET
    boto_bucket: _env:AWS_S3_BUCKET
    storage_path: /srv/docker
    smtp_host: localhost
    from_addr: docker@myself.com
    to_addr: my@myself.com

dev:
    loglevel: debug
    storage: local
    storage_path: /home/myself/docker

test:
    storage: local
    storage_path: /tmp/tmpdockertmp
Docker Registry的默认运行环境是dev, 如果你需要更改运行环境, 可通过环境变量SETTINGS_FLAVOR来指定, 例如, 通过执行如下可设定运行环境为prod.
export SETTINGS_FLAVOR=prod

指定配置文件位置

Docker Registry运行时可以通过环境变量DOCKER_REGISTRY_CONFIG指定config.yml的默认路径, 例如指定config.yml的默认位置为/opt/docker-registry/conf如下:
export DOCKER_REGISTRY_CONFIG=/opt/docker-registy/conf/config.yml

配置选项

通用配置选项包括loglevel, debug_versions, storage_redirect等, 其中logleve可以设置为info, debug, warn, error和critical级别.
# Default log level is infologlevel: _env:LOGLEVEL:info
授权选项包括standalone, index_endpoint和disable_token_auth等, standalone用来设定Docker Registry server为stand-alone模式, index_endpoint配置index endpoint的hostname, 通常用来验证用户登录时的密码, 默认是https://index.docker.io.
# By default, the registry acts standalone (eg: doesn‘t query the index)standalone: _env:STANDALONE:true# The default endpoint to use (if NOT standalone) is index.docker.ioindex_endpoint: _env:INDEX_ENDPOINT:https://index.docker.io# Token auth is enabled (if NOT standalone)disable_token_auth: _env:DISABLE_TOKEN_AUTH
搜索引擎选项search_backend用来设定后台搜索引擎, 如果为空, 则没有索引, 当前支持的backend为sqlalchemy.
# No search backendsearch_backend: _env:SEARCH_BACKEND# SQLite search backendsqlalchemy_index_database: _env:SQLALCHEMY_INDEX_DATABASE:sqlite:////tmp/docker-registry.db
存储选项storage设置存储引擎, Docker Registry默认存储引擎为file和s3, 也可以通过pip install docker-registry-driver-STORAGE_NAME来安装其他storage, 比如swift, gcs, glance等, 然后配置storage为STORAGE_NAME, 跟storage选项一起使用的是storage_path, 其用来指定存储数据的路径, 比如: /registry.
local:
  storage: file
  storage_path: /mnt/registry
  
prod:
  storage: s3
  s3_region: us-west-1
  s3_bucket: acme-docker
  storage_path: /registry
  s3_access_key: AKIAHSHB43HS3J92MXZ
  s3_secret_key: xdDowwlK7TJajV1Y7EoOZrmuPEJlHYcNP2k4j49T

第三步: 运行Docker Registry

准备Docker Registry的配置文件路径以及在dev, test, prod模式下存放images的路径.

mkdir -p /opt/docker-registry/{conf,dev,test,prod}

配置config.yml文件如下:

# All other flavors inherit the `common‘ config snippetcommon: &common# Default log level is info    loglevel: _env:LOGLEVEL:info# Enable the debugging /_versions endpoint    debug_versions: _env:DEBUG_VERSIONS:false# By default, the registry acts standalone (eg: doesn‘t query the index)    standalone: _env:STANDALONE:true# The default endpoint to use (if NOT standalone) is index.docker.io    index_endpoint: _env:INDEX_ENDPOINT:https://index.docker.io# Storage redirect is disabled    storage_redirect: _env:STORAGE_REDIRECT# Token auth is enabled (if NOT standalone)    disable_token_auth: _env:DISABLE_TOKEN_AUTH# No priv key    privileged_key: _env:PRIVILEGED_KEY# No search backend    search_backend: _env:SEARCH_BACKEND# SQLite search backend    sqlalchemy_index_database: _env:SQLALCHEMY_INDEX_DATABASE:sqlite:////tmp/docker-registry.db# Enable bugsnag (set the API key)    bugsnag: _env:BUGSNAG

local: &local<<: *common
    storage: local# This is the default configuration when no flavor is specifieddev: &dev<<: *local
    loglevel: _env:LOGLEVEL:debug
    debug_versions: _env:DEBUG_VERSIONS:true
    search_backend: _env:SEARCH_BACKEND:sqlalchemy
    storage_path: _env:STORAGE_PATH:/opt/docker-registry/dev# This flavor is used by unit teststest:<<: *dev
    standalone: true
    storage_path: _env:STORAGE_PATH:/opt/docker-registry/test# To specify another flavor, set the environment variable SETTINGS_FLAVOR# $ export SETTINGS_FLAVOR=prodprod:<<: *dev
    storage_path: _env:STORAGE_PATH:/opt/docker-registry/prod

运行Docker Registry(dev模式)

docker run  -p 5000:5000 -v /opt/docker-registry/conf/:/opt/docker-registry/conf/  -v /opt/docker-registry/dev:/opt/docker-registry/dev --name=test-docker-registry -e DOCKER_REGISTRY_CONFIG=/opt/docker-registry/conf/config.yml registry

其中设置volume /opt/docker-registry/dev为本地数据存储目录, –e DOCKER_REGISTRY_CONFIG=/opt/docer-registry/conf/config.yml为配置文件, 最后运行输出如下:

除此之外你也可以在浏览器上输入http://10.224.106.43:5000看到Docker Registry的运行模式, 当前运行模式为dev, 其输出信息如"docker-registry server (dev) (v0.8.1)".这时在/opt/docker-registry/dev目录下, 你能看到两个新的目录images和repositories, 这是新上传busybox的信息. 而且你可以在其他机器上从Docker Registry(10.224.106.43)上下载刚上传的image. 如:

[root@docker02 ~]# docker pull 10.224.106.43:5000/busyboxPulling repository 10.224.106.43:5000/busybox
a9eb17255234: Download complete

运行Docker Registry(prod模式)

通过环境变量SETTINGS_FLAVOR使得Docker Registry以prod模式运行, 运行命令如:

docker run -d -p 5000:5000 -v /opt/docker-registry/conf/:/opt/docker-registry/conf/  -v /opt/docker-registry/prod:/opt/docker-registry/prod --name=test-docker-registry -e DOCKER_REGISTRY_CONFIG=/opt/docker-registry/conf/config.yml -e SETTINGS_FLAVOR=prod registry

这时如果上传image,你能在/opt/docker-registry/prod下发现新上传的image数据, 而且也可以从其他机器下载新上传的image.
