3.6. 覆盖需要订阅的系统存储库

流程

1. 从 /etc/yum.repos.d/redhat.repo 文件中获取 baseurl ：

   # cat /etc/yum.repos.d/redhat.repo
   [AppStream]
   name = AppStream mirror example
   baseurl = https://mirror.example.com/RHEL-9/9.0/AppStream/x86_64/os/
   enabled = 1
   gpgcheck = 0
   sslverify = 1
   sslcacert = /etc/pki/ca1/ca.crt
   sslclientkey = /etc/pki/ca1/client.key
   sslclientcert = /etc/pki/ca1/client.crt
   metadata_expire = 86400
   enabled_metadata = 0

2. 配置存储库覆盖以使用相同的 baseurl，并将 rhsm 设为 true：

   {
       "x86_64": [
           {
               "name": "AppStream mirror example",
               "baseurl": "https://mirror.example.com/RHEL-9/9.0/AppStream/x86_64/os/",
               "gpgkey": "-----BEGIN PGP PUBLIC KEY BLOCK-----\n\n (…​)",
               "check_gpg": true,
               "rhsm": true
           }
       ]
   }

3. 重启 osbuild-composer.service ：

   $ sudo systemctl restart osbuild-composer.service
