<!--
|

In this tutorial you will learn how and why to externalize your microservice’s configuration.
|
||||
Specifically, you will learn how to use Kubernetes ConfigMaps and Secrets to set environment
|
||||
variables and then consume them using MicroProfile Config.
|
||||
-->
|
||||
在本教程中，你会学到如何以及为什么要实现外部化微服务应用配置。
|
||||
具体来说，你将学习如何使用 Kubernetes ConfigMaps 和 Secrets 设置环境变量，
|
||||
然后在 MicroProfile config 中使用它们。
|
||||
|
||||
## {{% heading "prerequisites" %}}

|
||||
### Creating Kubernetes ConfigMaps & Secrets
|
||||
There are several ways to set environment variables for a Docker container in Kubernetes,
|
||||
including: Dockerfile, kubernetes.yml, Kubernetes ConfigMaps, and Kubernetes Secrets. In the
|
||||
tutorial, you will learn how to use the latter two for setting your environment variables whose
|
||||
values will be injected into your microservices. One of the benefits for using ConfigMaps and
|
||||
Secrets is that they can be re-used across multiple containers, including being assigned to
|
||||
different environment variables for the different containers.
|
||||
-->
|
||||
### 创建 Kubernetes ConfigMaps 和 Secrets {#creating-kubernetes-configmaps-secrets}
|
||||
在 Kubernetes 中，为 docker 容器设置环境变量有几种不同的方式，比如：
|
||||
Dockerfile、kubernetes.yml、Kubernetes ConfigMaps、和 Kubernetes Secrets。
|
||||
在本教程中，你将学到怎么用后两个方式去设置你的环境变量，而环境变量的值将注入到你的微服务里。
|
||||
使用 ConfigMaps 和 Secrets 的一个好处是他们能在多个容器间复用，
|
||||
比如赋值给不同的容器中的不同环境变量。
|
||||
|
||||
<!--
|
||||
ConfigMaps are API Objects that store non-confidential key-value pairs. In the Interactive
|
||||
Tutorial you will learn how to use a ConfigMap to store the application's name. For more
|
||||
information regarding ConfigMaps, you can find the documentation
|
||||
[here](/docs/tasks/configure-pod-container/configure-pod-configmap/).
|
||||
|
||||
Although Secrets are also used to store key-value pairs, they differ from ConfigMaps in that
|
||||
they're intended for confidential/sensitive information and are stored using Base64 encoding.
|
||||
This makes secrets the appropriate choice for storing such things as credentials, keys, and
|
||||
tokens, the former of which you'll do in the Interactive Tutorial. For more information on
|
||||
Secrets, you can find the documentation [here](/docs/concepts/configuration/secret/).
|
||||
-->
|
||||
ConfigMaps 是存储非机密键值对的 API 对象。
|
||||
在互动教程中，你会学到如何用 ConfigMap 来保存应用名字。
|
||||
ConfigMap 的更多信息，你可以在[这里](/zh-cn/docs/tasks/configure-pod-container/configure-pod-configmap/)找到文档。
|
||||
|
||||
Secrets 尽管也用来存储键值对，但区别于 ConfigMaps 的是：它针对机密/敏感数据，且存储格式为 Base64 编码。
|
||||
secrets 的这种特性使得它适合于存储证书、密钥、令牌，上述内容你将在交互教程中实现。
|
||||
Secrets 的更多信息，你可以在[这里](/zh-cn/docs/concepts/configuration/secret/)找到文档。
|
||||
|
||||

<!--
|
||||
### Externalizing Config from Code
|
||||
Externalized application configuration is useful because configuration usually changes depending
|
||||
on your environment. In order to accomplish this, we'll use Java's Contexts and Dependency
|
||||
Injection (CDI) and MicroProfile Config. MicroProfile Config is a feature of MicroProfile, a set
|
||||
of open Java technologies for developing and deploying cloud-native microservices.
|
||||
-->
|
||||
### 从代码外部化配置
|
||||
外部化应用配置之所以有用处，是因为配置常常根据环境的不同而变化。
|
||||
为了实现此功能，我们用到了 Java 上下文和依赖注入（Contexts and Dependency Injection, CDI）、MicroProfile 配置。
|
||||
MicroProfile config 是 MicroProfile 的功能特性，
|
||||
是一组开放 Java 技术，用于开发、部署云原生微服务。
|
||||
|
||||
<!--
|
||||
CDI provides a standard dependency injection capability enabling an application to be assembled
|
||||
from collaborating, loosely-coupled beans. MicroProfile Config provides apps and microservices a
|
||||
standard way to obtain config properties from various sources, including the application, runtime,
|
||||
and environment. Based on the source's defined priority, the properties are automatically
|
||||
combined into a single set of properties that the application can access via an API. Together,
|
||||
CDI & MicroProfile will be used in the Interactive Tutorial to retrieve the externally provided
|
||||
properties from the Kubernetes ConfigMaps and Secrets and get injected into your application code.
|
||||
|
||||
Many open source frameworks and runtimes implement and support MicroProfile Config. Throughout
|
||||
the interactive tutorial, you'll be using Open Liberty, a flexible open-source Java runtime for
|
||||
building and running cloud-native apps and microservices. However, any MicroProfile compatible
|
||||
runtime could be used instead.
|
||||
-->
|
||||
CDI 提供一套标准的依赖注入能力，使得应用程序可以由相互协作的、松耦合的 beans 组装而成。
|
||||
MicroProfile Config 为 app 和微服务提供从各种来源，比如应用、运行时、环境，获取配置参数的标准方法。
|
||||
基于来源定义的优先级，属性可以自动的合并到单独一组应用可以通过 API 访问到的属性。
|
||||
CDI & MicroProfile 都会被用在互动教程中，
|
||||
用来从 Kubernetes ConfigMaps 和 Secrets 获得外部提供的属性，并注入应用程序代码中。
|
||||
|
||||
很多开源框架、运行时支持 MicroProfile Config。
|
||||
对于整个互动教程，你都可以使用开放的库、灵活的开源 Java 运行时，去构建并运行云原生的 apps 和微服务。
|
||||
然而，任何 MicroProfile 兼容的运行时都可以用来做替代品。
