我们的Docker私有仓库Registry服务只有加了认证机制之后我们的Registry服务才会更加的安全可靠。赶快跟随以下步骤来增加认证机制吧。

创建密码

创建docker registry工作目录

mkdir -p /data/docker.registry

创建将保存凭据的文件夹

mkdir -p /data/docker.registry/etc/registry/auth

安装htpasswd工具。

yum -y install httpd-tools

创建管理员admin，存入/data/docker.registry/etc/registry/auth/passwd里面，此passwd文件将包含登录凭据和加密的passwd

htpasswd -Bbn admin 123456 > /data/docker.registry/etc/registry/auth/passwd

验证密码

cat /data/docker.registry/etc/registry/auth/passwd
admin:$2y$05$3R0Y9nlTM.DQEAgSrGCdp.zFMkeRr8ILeK6kW/o0kvlagZLlpUmDG

启动Registry

配置Registry删除权限
默认安装的Registry不支持删除

# vi /data/docker.registry/etc/registry/config.yml 
version: 0.1
log:
  fields:
    service: registry
storage:
  cache:
    blobdescriptor: inmemory
  filesystem:
    rootdirectory: /var/lib/registry
  delete: #配置删除权限,默认安装的Registry不支持删除
    enabled: true
http:
  addr: :5000
  headers:
    X-Content-Type-Options: [nosniff]
health:
  storagedriver:
    enabled: true
    interval: 10s
    threshold: 3

密码创建完成，将凭据添加到注册表中。在这里,将auth目录和config.xml配置文件挂载到容器中:

docker run -d -p 5000:5000 \
--restart=always \
--name registry_private \
-v /data/docker.registry/etc/registry/auth:/etc/registry/auth \
-v /data/docker.registry/etc/registry/config.yml:/etc/docker/registry/config.yml \
-v /data/docker.registry/var/lib/registry:/var/lib/registry \
-e "REGISTRY_AUTH=htpasswd" \
-e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
-e "REGISTRY_AUTH_HTPASSWD_PATH=/etc/registry/auth/passwd" \
registry:latest

成功后会在/root/.docker/config.json 保存5000端口的密码，启动registry-web会用到，如下图：
docker配置htpasswd,容器化,docker,运维
3. 测试

[root@test data]# docker tag registry:latest 127.0.0.1:5000/registry:latest
[root@test data]# docker push 127.0.0.1:5000/registry
The push refers to repository [127.0.0.1:5000/registry]
fb6b1a93008f: Preparing
6d2d8cb41f01: Preparing
4f5aa08c5eaa: Preparing
8ebb9d6ed165: Preparing
0fcbbeeeb0d7: Preparing
no basic auth credentials

认证

[root@test data]# docker login 127.0.0.1:5000 # admin/123456
Username (): admin
Password:
Login Succeeded

重试推送

[root@test data]# docker push 127.0.0.1:5000/registry
The push refers to repository [127.0.0.1:5000/registry]
fb6b1a93008f: Pushed
6d2d8cb41f01: Pushed
4f5aa08c5eaa: Pushed
8ebb9d6ed165: Pushed
0fcbbeeeb0d7: Pushed
latest: digest: sha256:a0dd61073ad21122e5f1517682800272ef29df52041aaea7ee29e92a5d22aa28 size: 1363

凭据保存在 .docker/config.json中:

[root@test data]# cat ~/.docker/config.json
{
“auths”: {
“127.0.0.1:5000”: {
“auth”: “YWRtaW46ZkZHHGGluVDQ1SA==”
}
}
}

注意： 在使用凭据时建议使用https.

使用

登录
docker login 172.x.x.x:5000
输入用户名密码 admin/123456

查看镜像

浏览器访问：http:// 172.x.x.x:5000/v2/_catalog
输入用户名/密码admin/123456

查询镜像标签列表

curl -u admin:123456 ‘http:// 127.0.0.1:5000/v2/qingzhu-backend-gray/tags/list’

安装 registry-web

平时对仓库镜像的管理，如果仅通过接口请求来操作仓库镜像，还是挺麻烦的。
hyper/docker-registry-webUI是一款轻量级的管理界面

# 拉取镜像
docker pull hyper/docker-registry-web
# 启动容器 --link registry_private 是我以前安装的 Registry 
docker rm -f registry-web
docker run -d \
-p 8000:8080 \
--name registry-web\
--restart=always \
--link registry_private \
-e registry_url=http://registry_private:5000/v2 \
-e registry_name=registry_private \
-e REGISTRY_TRUST_ANY_SSL=false   \
-e REGISTRY_BASIC_AUTH="YWRtaW46ZkZ0WWluVDQ1SA==" \
-e registry_auth_enabled=false \
-e registry_readonly=false \
hyper/docker-registry-web:latest

docker logs -f registry-web

浏览器访问：

http://172.x.x.x:8000

启用registry-web登录认证

令牌身份验证需要PEM格式的RSA私钥以及与该密钥匹配的证书

生成私钥和证书

mkdir conf
openssl req -new -newkey rsa:4096 -days 365 -subj "/CN=localhost" \
        -nodes -x509 -keyout conf/auth.key -out conf/auth.cert

创建registry配置 conf/registry-srv.yml

version: 0.1    

storage:
  filesystem:
    rootdirectory: /var/lib/registry
    
http:
  addr: 0.0.0.0:5000   
    
auth:
  token:
    # external url to docker-web authentication endpoint
    realm: http://localhost:8080/api/auth
    # should be same as registry.name of registry-web
    service: localhost:5000
    # should be same as registry.auth.issuer of registry-web
    issuer: 'my issuer'
    # path to auth certificate
    rootcertbundle: /etc/docker/registry/auth.cert

Start docker registry

docker run -v $(pwd)/conf/registry-srv.yml:/etc/docker/registry/config.yml:ro \
            -v $(pwd)/conf/auth.cert:/etc/docker/registry/auth.cert:ro -p 5000:5000  --name registry-srv -d registry:2

Create configuration file conf/registry-web.yml

registry:
  # Docker registry url
  url: http://registry-srv:5000/v2
  # Docker registry fqdn
  name: localhost:5000
  # To allow image delete, should be false
  readonly: false
  auth:
    # Enable authentication
    enabled: true
    # Token issuer
    # should equals to auth.token.issuer of docker registry
    issuer: 'my issuer'
    # Private key for token signing
    # certificate used on auth.token.rootcertbundle should signed by this key
    key: /conf/auth.key

Start registry-web

docker run -v $(pwd)/conf/registry-web.yml:/conf/config.yml:ro \
           -v $(pwd)/conf/auth.key:/conf/auth.key -v $(pwd)/db:/data \
           -it -p 8080:8080 --link registry-srv --name registry-web hyper/docker-registry-web
