1.Docker registry 说明本文记录的个人完整搭建docker registry操作过程，官方虽然提供了Docker Hub作为一个公开的集中仓库，但是天朝的网络可想而知，第一次pull一个镜像不是失败就是时间很长，为了解决这个问题需要创建一个私有的仓库在本地pull 本地push。我使用的docker版本是:1.5.0
2、安装docker-registry
复制代码代码如下:docker run -d -e SETTINGS_FLAVOR=dev -e STORAGE_PATH=/tmp/registry -v /alidata/registry:/tmp/registry -p 5000:5000 registry# 如果本地没有下载过docker-registry，则首次会pull registry 运行时会映射路径和端口，以后就可以从/data/registry下找到私有仓库
3、客户端上的操作#从本地仓库上获取有哪些镜像复制代码代码如下:curl -X GET http://registry.wpython.com:5000/v1/search curl http://registry.wpython.com:5000/v1/search{\”num_results\”: 1, \”query\”: \”\”, \”results\”: [{\”description\”: \”\”, \”name\”: \”library/centos6\”}]}
# 拉取到本地复制代码代码如下:docker pull library/centos6
# tag 一个镜像复制代码代码如下:docker tag 8552ea9a16f9 registry.wpython.com:5000/centos6_x86_64.mini
# 将新的docker images push 到本地仓库复制代码代码如下:docker push registry.wpython.com:5000/centos6_x86_64.mini
4、加入nginx认证Docker 启动监听端口后，使用的是 http，可以远程来管理 Docker 主机。这样的场景存在弊端，API 层面是没有提供用户验证、Token 之类身份验证功能，任何人都可以通过地址加端口来控制 Docker 主机，为了避免这样的情况发生，Docker 官方也支持 https 方式，不过需要我们自己来生成证书。新版本的docker 也强制必须使用https否则会报错
# 安装nginx过程略创建一个登陆用户(如果没有htpasswd命令 请安装httpd-tools这个包)
复制代码代码如下:htpasswd -c /alidata/server/nginx/docker-registry.htpasswd adminNew password: Re-type new password: Adding password for user admin
# 生成根密钥复制代码代码如下:cd /etc/pki/CA/openssl genrsa -out private/cakey.pem 2048
# 生成根证书复制代码代码如下:openssl req -new -x509 -key private/cakey.pem -out cacert.pemCountry Name (2 letter code) [AU]:CNState or Province Name (full name) [Some-State]:BrijingLocality Name (eg, city) []:ChaoyangOrganization Name (eg, company) [Internet Widgits Pty Ltd]:Organizational Unit Name (eg, section) []:Common Name (e.g. server FQDN or YOUR name) []:registry.wpython.comEmail Address []:
# 为nginx服务器生成ssl密钥复制代码代码如下:cd /alidata/server/nginx/ssl openssl genrsa -out nginx.key 2048
# 为nginx生成的证书签署请求复制代码代码如下: openssl req -new -key nginx.key -out nginx.csrYou are about to be asked to enter information that will be incorporatedinto your certificate request.What you are about to enter is what is called a Distinguished Name or a DN.There are quite a few fields but you can leave some blankFor some fields there will be a default value,If you enter \’.\’, the field will be left blank.—–Country Name (2 letter code) [AU]:CNState or Province Name (full name) [Some-State]:BeijingLocality Name (eg, city) []:ChaoyangOrganization Name (eg, company) [Internet Widgits Pty Ltd]:Organizational Unit Name (eg, section) []:Common Name (e.g. server FQDN or YOUR name) []:registry.wpython.comEmail Address []:Please enter the following \’extra\’ attributesto be sent with your certificate requestA challenge password []:An optional company name []:
# 私有CA根据请求来签发证书复制代码代码如下:openssl ca -in nginx.csr -out nginx.crt# 如果报如下错误：Using configuration from /usr/local/ssl/openssl.cnf/etc/pki/CA/index.txt: No such file or directoryunable to open \’/etc/pki/CA/index.txt\’140137408210600:error:02001002:system library:fopen:No such file or directory:bss_file.c:398:fopen(\’/etc/pki/CA/index.txt\’,\’r\’)140137408210600:error:20074002:BIO routines:FILE_CTRL:system lib:bss_file.c:400:# 执行以下命令复制代码代码如下:cd /etc/pki/CA/mkdir newcerts touch index.txt touch serial echo 01 > serialcd – openssl ca -in nginx.csr -out nginx.crtUsing configuration from /usr/local/ssl/openssl.cnfCheck that the request matches the signatureSignature okCertificate Details: Serial Number: 1 (0x1) Validity Not Before: May 12 04:15:08 2015 GMT Not After : May 11 04:15:08 2016 GMT Subject: countryName = CN stateOrProvinceName = Beijing organizationName = Internet Widgits Pty Ltd commonName = registry.wpython.com emailAddress = 739827282@qq.com X509v3 extensions: X509v3 Basic Constraints: CA:FALSE Netscape Comment: OpenSSL Generated Certificate X509v3 Subject Key Identifier: B5:20:C7:47:26:D9:26:54:12:F7:36:7E:4E:3A:F0:D9:0E:2C:F7:BD X509v3 Authority Key Identifier: keyid:93:F7:86:72:1B:2B:24:CD:AF:24:EF:53:F4:E1:FA:EC:E7:70:1A:90Certificate is to be certified until May 11 04:15:08 2016 GMT (365 days)Sign the certificate?

# 发现根证书
复制代码代码如下:# cp /etc/pki/tls/certs/ca-bundle.crt{,.bak} 备份以防出错# cat /etc/pki/CA/cacert.pem >> /etc/pki/tls/certs/ca-bundle.crt
# 创建nginx配置文件复制代码代码如下:# vi /alidata/server/nginx/conf/vhosts/www.wpython.com.confupstream docker-registry { server localhost:5000;} server { listen 8080; server_name registry.wpython.com; # enabled ssl ssl on; ssl_certificate /alidata/server/nginx/ssl/nginx.crt; ssl_certificate_key /alidata/server/nginx/ssl/nginx.key; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; client_max_body_size 0; chunked_transfer_encoding on; location / { auth_basic \”Restricted\”; auth_basic_user_file docker-registry.htpasswd; proxy_pass http://docker-registry; } location /_ping { auth_basic off; proxy_pass http://docker-registry; } location /v1/_ping { auth_basic off; proxy_pass http://docker-registry; }}
