Git as your state store. Anything that complies with this principle can be used in GitOps (S3 storage, for example). However, in this book we will be focusing on using Git as the state store. Chapter desired state is pulled from configuration information that is versioned and stored in an immutable storage system. If there is a difference between the de- sired and running states, they are reconciled by to the private key that is stored on the system. If you’re managing many clusters, managing the storage process at scale can become an issue. This private key needs to be installed on every Sealed Secret

此需要预留固定的公网 IP 地址，绑定给特定的虚拟机使用，使得 重启后，通过固定的 IP 地址仍然能够访问。 对象存储 是公有云提供的一种新型的存储服务，英文是 Object-based Storage。不同的云厂商对它有不同的英文缩写命名。例如阿里 云把自家的对象存储服务叫做 OSS，华为云叫 OBS，腾讯云叫 COS。与传统块存储不同的是，第一，操作对象上是对象 （Object），而不是文本文件中文本；第二，存储方式通过
