1.
首先，构建用于
Linux
的二进制文件：
make build-linux
2.
然后构建
Docker
镜像：
export DAPR_REGISTRY=docker.io/<your Docker account>
export DAPR_TAG=dev
make docker-build
make docker-push
3.
如果你之前使用
Helm
或
build
脚本部署了
Dapr
，请先使用
Helm
删除它。
helm delete dapr --purge
4.
最后，部署新的
Dapr
构建：
make docker-deploy-k8s

小结
Dapr
为应用程序提供了简单的基于
key/value
的状态
API
来存储状态。该
API
隐藏了底层数据存储的细节，从而使应用开发者从对这些操作的关注中
解脱出来。
Dapr
使用模块化架构，允许新的状态存储以
Dapr
组件的方式插入。
Dapr
以
Redis
作为默认的状态存储，但社区已经贡献了越来越多的数据存储列表，涵
盖了很多流行的开源选项和云平台。
Dapr
支持不同的并发模型和一致性模型，允许将额外的元数据附加到请求中，
以便利用存储的特定功能。虽然状态访问代码通常是可移植的，但在决定使
用哪些状态存储时，需要了解不同存储实现之间的微妙差异以及特定存储的
限制。可以通过自定义中间件进一步定制状态处理，在中间件中可以应用额
外的数据转换，如加密
/
解密、压缩和标准化。
在下一章中，我们将把关注点转移到集成上。我们将讨论
Dapr
如何启用各种
消息模式，你可以使用这些模式来构建松耦合的、 ...
