1 准备工作

• 创建一个文件夹registry,后续专门在该文件下操作；
• 拥有一个私有仓库地址，比如demo.testdocker.com。

2 准备站点证书

注意：以下是使用 openssl 自行签发demo.testdocker.com 的站点 SSL 证书。

2.1 创建CA私钥

$ sudo openssl genrsa -out "root-ca.key" 4096

2.2 创建CA根证书请求文件

sudo openssl req -new -key "root-ca.key" -out "root-ca.csr" -sha256 -subj '/C=CN/ST=Shanxi/L=Xian/O=Company/CN=Company Docker Registry CA'

2.3 配置CA根证书

• 新建root-ca.cnf：
  

• 并写入如下内容：

[root_ca]
basicConstraints = critical,CA:TRUE,pathlen:1
keyUsage = critical, nonRepudiation, cRLSign, keyCertSign
subjectKeyIdentifier=hash

2.4 签发根证书

sudo openssl x509 -req -days 3650 -in "root-ca.csr" -signkey "root-ca.key" -sha256 -out "root-ca.crt" -extfile "root-ca.cnf" -extensions root_ca

2.5 生成站点SSL私钥

sudo openssl genrsa -out "demo.testdocker.com.key" 4096

2.6 私钥生成证书请求文件

sudo openssl req -new -key "demo.testdocker.com.key" -out "site.csr" -sha256 -subj '/C=CN/ST=Shanxi/L=Xian/O=Company/CN=demo.testdocker.com'

2.7 配置证书

• 新建 site.cnf 文件：

• 写入如下内容：

[server]
authorityKeyIdentifier=keyid,issuer
basicConstraints = critical,CA:FALSE
extendedKeyUsage=serverAuth
keyUsage = critical, digitalSignature, keyEncipherment
subjectAltName = DNS:demo.testdocker.com, IP:127.0.0.1
subjectKeyIdentifier=hash

2.8 签署站点SSL证书

sudo openssl x509 -req -days 750 -in "site.csr" -sha256 -CA "root-ca.crt" -CAkey "root-ca.key" -CAcreateserial -out "demo.testdocker.com.crt" -extfile "site.cnf" -extensions server

此时拥有了 demo.testdocker.com 的网站 SSL 私钥 demo.testdocker.com.key 和 SSL 证书
demo.testdocker.crt 及 CA 根证书 root-ca.crt

ssl 文件夹并将 docker.domain.com.key docker.domain.com.crt root-ca.crt 这
三个文件移入，删除其他文件

3 配置私有仓库

• 私有仓库默认的配置文件位于 /etc/docker/registry/config.yml:

version: 0.1
log:
  accesslog:
    disabled: true
  level: debug
  formatter: text
  fields:
    service: registry
    environment: staging
storage:
  delete:
    enabled: true
  cache:
    blobdescriptor: inmemory
  filesystem:
    rootdirectory: /var/lib/registry
auth:
  htpasswd:
    realm: basic-realm
    path: /etc/docker/registry/auth/nginx.htpasswd
http:
  addr: :443
  host: https://demo.testdocker.com
  headers:
    X-Content-Type-Options: [nosniff]
  http2:
    disabled: false
  tls:
    certificate: /etc/docker/registry/ssl/demo.testdocker.com.crt
    key: /etc/docker/registry/ssl/demo.testdocker.com.key
health:
  storagedriver:
    enabled: true
    interval: 10s
threshold: 3

4 生成 http 认证文件

• 创建auth文件夹：
  
• 执行如下命令：

sudo docker run --rm --entrypoint htpasswd httpd:alpine -Bbn noamanelson 123456 > auth/nginx.htpasswd

noamanelson@noamanelson-Virtual-Machine:/etc/docker/registry$ sudo docker run --rm --entrypoint htpasswd httpd:alpine -Bbn noamanelson 123456 > auth/nginx.htpasswd

Status: Downloaded newer image for httpd:alpine
noamanelson@noamanelson-Virtual-Machine:/etc/docker/registry$ 

• 编辑编辑 docker-compose.yml：
  

version: '3'

ervices:
  registry:
    image: registry
    ports:
      - "443:443"
    volumes:
      - ./:/etc/docker/registry
      - registry-data:/var/lib/registry
volumes:
  registry-data:

5 修改hosts文件

• sudo vim /etc/hosts

6 启动

• 使用命令提示找不到，需要安装：

noamanelson@noamanelson-Virtual-Machine:/etc/docker/registry$ sudo docker-compose up -d
sudo: docker-compose：找不到命令

• 安装docker-compose：

sudo apt-get install docker-compose

• 再次启动，又报错了：
  
• 应为docker-compose的版本不对，重新卸载docker-compose：

sudo apt-get remove docker-compose

• 再次安装：

sudo apt-get update
sudo apt-get install docker-compose-plugin

• 启动：

sudo docker compose up -d

7 测试私有仓库

7.1 移动证书

• 由于自行签发的 CA 根证书不被系统信任，所以我们需要将 CA 根证书 ssl/root-ca.crt 移入 /etc/docker/certs.d/docker.test.com 文件夹中：

sudo mkdir -p /etc/docker/certs.d/demo.testdocker.com
sudo cp ssl/root-ca.crt /etc/docker/certs.d/demo.testdocker.com/ca.crt

7.2 登陆仓库

• sudo docker login demo.testdocker.com：
  

7.3 拉取推送镜像

# noamanelson是我的用户名，改为自己的即可
sudo docker pull ubuntu:18.04
sudo docker tag ubuntu:18.04 docker.domain.com/noamanelson/ubuntu:18.04
sudo docker push docker.domain.com/noamanelson/ubuntu:18.04
sudo docker image rm docker.domain.com/noamanelson/ubuntu:18.04
sudo docker pull docker.domain.com/noamanelson/ubuntu:18.04

7.4 退出登陆，并推送镜像

docker logout docker.domain.com
docker push docker.domain.com/noamanelson/ubuntu:18.04
