红帽全球峰会16.5. 验证镜像签名
您可以启用镜像签名验证，以确保您的镜像服务(glance)镜像在计算服务(nova)启动实例前不包含未授权的更改。启用此功能后，您可以防止新实例启动，其中可能包括恶意软件或安全漏洞。
流程
在 heat 模板中，通过将
True的值设置为VerifyGlanceSignatures参数来启用实例签名验证：parameter_defaults: VerifyGlanceSignatures: Trueparameter_defaults: VerifyGlanceSignatures: TrueCopy to Clipboard Copied! Toggle word wrap Toggle overflow -
确保用于修改
VerifyGlanceSignatures参数的模板包含在openstack overcloud deployscript 中，并重新运行 deploy 脚本。
注意
如果您使用没有签名的镜像创建实例，则镜像会失败，且实例不会启动。有关签名镜像的更多信息，请参阅签名镜像。
