搭建私有Docker Registry

Docker的Docker Hub是一個公有的Registry, 從Docker Hub上可以找到很多的官方或個人構建的Docker Image, 通常, 這些p_w_picpath能滿足開發、測試的需求.  但是如果想構建的p_w_picpath只在控制範圍內共享, 而不是開放環境, 那就得搭建自己的私有Docker Registry. Docker官方實現了docker-registy, 根據官方的說明可以搭建自己的Docker Registry, 官方有兩種方式搭建Docker Registry, 一種是按傳統的部署軟件的方法安裝Docker Registry,  詳細可參考Matthew Fisher的博客, 另一種是通過官方構建的Docker p_w_picpath來搭建Docker Registry. 本文簡單介紹如何通過官方Docker p_w_picpath搭建自己的私有Docker Registry.

 

第一步: 下載官方Registry Docker Image

docker pull registry:latest

第二步: 準備配置文件

• 創建配置文件

Docker Registry自帶一個config_sample.yml配置文件, 通常將這個文件重命名爲config.yml作爲基本配置文件.

• 配置flavors

Docker Registry可以以幾種flavors運行, 這使得Docker Registry可以運行在開發模式, 產線模式或者自定義的模式. 從配置文件config_sample.yml可知包括如下的一些flavors.

common:  作爲其他flavors的基本配置.

local:  將數據存放在本地文件系統.

s3: 使用AWS S3存放數據.

dev: 使用local flavor作爲基本配置.

test: 作爲單元測試的flavor.

prod: 默認使用s3 flavor作爲產線配置.

除此之外, 也可以使用OpenStack的swift, glance, glance-swift來存放數據, 還有key/value存儲elliptics, 以及Google Cloud Storage GCE來存放數據.  除前所述的內置flavors, 也可以自定義flavor. 下面是一個簡單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: [email protected]
    to_addr: [email protected]

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

test:
    storage: local
    storage_path: /tmp/tmpdockertmp

Docker Registry的默認運行環境是dev, 如果你需要更改運行環境, 可通過環境變量SETTINGS_FLAVOR來指定, 例如, 通過執行如下可設定運行環境爲prod.

export SETTINGS_FLAVOR=prod

• 指定配置文件位置

Docker Registry運行時可以通過環境變量DOCKER_REGISTRY_CONFIG指定config.yml的默認路徑,  例如指定config.yml的默認位置爲/opt/docker-registry/conf如下:

export DOCKER_REGISTRY_CONFIG=/opt/docker-registy/conf/config.yml

• 配置選項

通用配置選項包括loglevel, debug_versions, storage_redirect等, 其中logleve可以設置爲info, debug, warn, error和critical級別.

# Default log level is infologlevel: _env:LOGLEVEL:info

授權選項包括standalone, index_endpoint和disable_token_auth等, standalone用來設定Docker Registry server爲stand-alone模式, index_endpoint配置index endpoint的hostname, 通常用來驗證用戶登錄時的密碼, 默認是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

搜索引擎選項search_backend用來設定後臺搜索引擎, 如果爲空, 則沒有索引, 當前支持的backend爲sqlalchemy.

# No search backendsearch_backend: _env:SEARCH_BACKEND# SQLite search backendsqlalchemy_index_database: _env:SQLALCHEMY_INDEX_DATABASE:sqlite:////tmp/docker-registry.db

存儲選項storage設置存儲引擎, Docker Registry默認存儲引擎爲file和s3, 也可以通過pip install docker-registry-driver-STORAGE_NAME來安裝其他storage, 比如swift, gcs, glance等, 然後配置storage爲STORAGE_NAME, 跟storage選項一起使用的是storage_path, 其用來指定存儲數據的路徑, 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: 運行Docker Registry

• 準備Docker Registry的配置文件路徑以及在dev, test, prod模式下存放p_w_picpaths的路徑.

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

• 運行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

其中設置volume /opt/docker-registry/dev爲本地數據存儲目錄, –e DOCKER_REGISTRY_CONFIG=/opt/docer-registry/conf/config.yml爲配置文件, 最後運行輸出如下:

除此之外你也可以在瀏覽器上輸入http://10.224.106.43:5000看到Docker Registry的運行模式, 當前運行模式爲dev, 其輸出信息如"docker-registry server (dev) (v0.8.1)".這時在/opt/docker-registry/dev目錄下, 你能看到兩個新的目錄p_w_picpaths和repositories, 這是新上傳busybox的信息. 而且你可以在其他機器上從Docker Registry(10.224.106.43)上下載剛上傳的p_w_picpath. 如:

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

• 運行Docker Registry(prod模式)

通過環境變量SETTINGS_FLAVOR使得Docker Registry以prod模式運行, 運行命令如:

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

這時如果上傳p_w_picpath,你能在/opt/docker-registry/prod下發現新上傳的p_w_picpath數據, 而且也可以從其他機器下載新上傳的p_w_picpath.
