Quay和Clair的集成

版本基于Quay 3.2 ，Clair 3.2

1.搭建DNS named

2.搭建Quay的基础服务

参考

https://www.cnblogs.com/ericnie/p/12233269.html

这里更新一个地方，在配置的时候，生成SSL的key后直接写在配置界面上。

 

 然后选择security scanner,把key id记录下来，比如

700660d27213683afbeafa8da4af9b53ff933dba4b8614e39c1bd717cf84f72c

直接在/mnt/quay/config下解压文件所得 

[root@registry config]# ls
config.yaml  extra_ca_certs  quay-config.tar.gz  ssl.cert  ssl.key

启动quay，打开quay的界面转到superuser可以看到key,千万别删除，千万别删除，千万别删除。

注意启动quay以后，需要保证jwtproxy服务启动

[root@f2072855dcac quay-registry]# ps -aux | grep jwtproxy
root       196  0.0  0.1 303656 13620 ?        Sl   10:14   0:00 /usr/local/bin/jwtproxy --config /quay-registry/conf/jwtproxy_conf.yaml
root       552  0.0  0.0  10692   976 ?        R+   10:43   0:00 grep --color=auto jwtproxy

 3.配置clair

docker run --name postgres -p 5432:5432 -d postgres
sleep 5
docker run --rm --link postgres:postgres postgres 
   sh -c 'echo "create database clairtest" | psql -h 
   "$POSTGRES_PORT_5432_TCP_ADDR" -p  
   "$POSTGRES_PORT_5432_TCP_PORT" -U postgres'

mkdir /clair-config

config.xml

[root@registry config]# cat /clair-config/config.yaml 
clair:
  database:
    type: pgsql
    options:

    # https://clair.mycompany.com, the health will be reported at
    # http://clair.mycompany.com:6061/health.
    healthport: 6061

    port: 6062
    timeout: 900s

    # paginationkey can be any random set of characters. *Must be the same across all Clair instances*.
    paginationkey: "XxoPtCUzrUv4JV5dS+yQ+MdW7yLEJnRMwigVY/bpgtQ="

  updater:
    # interval defines how often Clair will check for updates from its upstream vulnerability databases.
    interval: 6h
    notifier:
      attempts: 3
      renotifyinterval: 1h
      http:
        # QUAY_ENDPOINT defines the endpoint at which Quay is running.
        # For example: https://myregistry.mycompany.com
        endpoint: https://registry.example.com/secscan/notify

jwtproxy:
  signer_proxy:
    enabled: true

      private_key:
        type: preshared
        options:
          # The ID of the service key generated for Clair. The ID is returned when setting up
          # the key in [Quay Setup](security-scanning.md)
          key_id: 700660d27213683afbeafa8da4af9b53ff933dba4b8614e39c1bd717cf84f72c
          private_key_path: /clair/config/security_scanner.pem


  verifier_proxies:
  - enabled: true
    # The port at which Clair will listen.
    listen_addr: :6060

    # If Clair is to be served via TLS, uncomment these lines. See the "Running Clair under TLS"
    # section below for more information.
    # key_file: /clair/config/clair.key

    verifier:
      # CLAIR_ENDPOINT is the endpoint at which this Clair will be accessible. Note that the port
      # specified here must match the listen_addr port a few lines above this.
      # Example: https://myclair.mycompany.com:6060
      audience: http://registry.example.com:6060

      upstream: http://localhost:6062
      key_server:
        type: keyregistry

          registry: https://registry.example.com/keys/

[root@registry clair-config]# ls
config.yaml  security_scanner.pem

启动clair

docker run --restart=always -p 6060:6060 -p 6061:6061 
   -v /clair-config:/clair/config 
   -v /mnt/quay/config/extra_ca_certs/rootCA.crt:/etc/pki/ca-trust/source/anchors/ca.crt  
   quay.io/redhat/clair-jwt:v3.2.0

4.push镜像，验证

cp rootCA.pem /etc/docker/certs.d/registry.redhat.ren/ca.crt

[root@registry ~]# docker push registry.example.com/admin/debian34:9.5
The push refers to a repository [registry.example.com/admin/debian34]
f715ed19c28b: Pushed

转到quay界面

关键坑

• DNS

因为无论是quay还是clair启动都会需要根据域名访问对方，所以需要配置dns

需要修改宿主机的/etc/reslov.conf, quay和clair启动中会去读取dns记录

虚拟机重启以后/etc/reslov.conf会修改，记住改回

• Quay和Clair间的Key

这个也比较坑，设置为preshard模式吧。

• Jwtproxy

一开始运行的时候会有此进程，但如果docker restart后这个就没有了。

• Clair的config.yaml

折腾好几天。。。。
