三分钟游览

从三秒游结束的地方开始，本节将介绍 Skipper 的附加命令和其他功能。每个部分演练了同一组作，但针对不同的平台：spring-doc.cadn.net.cn

8. 本地机器

启动服务器和 shell，就像在三秒游中一样。spring-doc.cadn.net.cn

现在，您可以安装并更新 Hello World 应用程序。首先运行package install命令，如以下示例所示（及其输出）：spring-doc.cadn.net.cn

skipper:>package install --release-name helloworldlocal --package-name helloworld --package-version 1.0.0 --properties spec.applicationProperties.server.port=8099
Released helloworldlocal. Now at version v1.

您现在可以卷曲greetingendpoint，如以下示例所示（及其输出）：spring-doc.cadn.net.cn

$ curl http://localhost:8099/greeting
Hello World!
$ curl http://localhost:8099/about
Hello World v1.0.0.RELEASE

我们使用 YAML 文件来更新版本。此应用程序包含一个 Spring Boot@ConfigurationProperty叫helloworld.greeting，因此我们将其与标准 Spring Boot 属性一起设置：endpoints.sensitive=false. 我们还将内存提升到 2G，使引导执行器端点不敏感，并将端口设置为 8100。spring-doc.cadn.net.cn

这helloworld-upgrade-local.yml文件包含以下代码：spring-doc.cadn.net.cn

spec:
  applicationProperties:
    server.port: 8100
    endpoints.sensitive: false
    helloworld.greeting: yo
  deploymentProperties:
    spring.cloud.deployer.memory: 2048m

以下示例显示了release upgrade命令，其输出：spring-doc.cadn.net.cn

skipper:>release upgrade --release-name helloworldlocal --package-name helloworld --package-version 1.0.1 --file /home/mpollack/helloworld-upgrade-local.yml
helloworldlocal has been upgraded.  Now at version v2.

这--package-version 1.0.1命令行选项也用于升级到较新版本的软件包。spring-doc.cadn.net.cn

当前的升级策略很简单：如果新应用程序正常，则删除旧应用程序。没有滚动升级选项。部署并检查所有新应用的运行状况。然后删除所有以前的版本。计划在 Skipper 的未来版本中提供更灵活的升级策略。spring-doc.cadn.net.cn

您现在可以卷曲greetingendpoint 和aboutendpoint，如以下示例所示（及其输出）：spring-doc.cadn.net.cn

$ curl http://localhost:8100/greeting
yo
$ curl http://localhost:8100/about
Hello World v1.0.1.RELEASE

您还可以在浏览器中查看端点。spring-doc.cadn.net.cn

这list命令显示当前DEPLOYED和DELETED每个发布名称的发布。在本例中，只有一个条目，正如您在release list命令，如下所示：spring-doc.cadn.net.cn

skipper:>release list

（一个manifest diff命令将在未来的版本中推出。spring-doc.cadn.net.cn

现在我们可以使用rollback命令来部署旧版本的应用程序。由于我们拥有该版本的清单，因此我们拥有重新部署早期版本所需的一切，如以下示例所示（及其输出）：spring-doc.cadn.net.cn

skipper:>release rollback --release-name helloworldlocal --release-version 1
helloworldlocal has been rolled back.  Now at version v3.

历史记录现在显示新的v3版本，即使它在应用程序行为方面与v1版本。

9. 云代工

首先，按照在 Cloud Foundry 上安装一节中的说明将 Skipper Server 部署到 Cloud Foundry。spring-doc.cadn.net.cn

当您启动 Skipper shell 时，默认情况下，它会尝试在同一台（本地）机器上查找 Skipper 服务器。要指定在 Cloud Foundry 上运行的 Skipper 服务器，请提供serverUrl启动 shell 时或使用config命令。以下示例提供了serverUrl:spring-doc.cadn.net.cn

java -jar spring-cloud-skipper-shell-2.11.5.jar --spring.cloud.skipper.client.serverUri=https://mlp-skipper.cfapps.io/api

以下示例使用config:spring-doc.cadn.net.cn

skipper:>skipper config --uri https://mlp-skipper.cfapps.io/api
Successfully targeted https://mlp-skipper.cfapps.io/api

这repo list命令显示experimental和local存储库，因为它们是默认配置的。这local存储库是您可以上传新包的地方。这experimental存储库有一些“Hello World”应用程序可以帮助您入门。以下示例显示了repo list命令和我们示例的输出：spring-doc.cadn.net.cn

skipper:>repo list
╔════════════╤═══════════════════════════════════════════════════════════╤═════╤═════╗

╚════╧════════════╧═════════════════════════════════════════════════════════════════════════╝

在前面的示例中，只有一个 Cloud Foundry 平台。spring-doc.cadn.net.cn

现在我们可以安装 Hello World 应用程序（特别是基于 maven 的工件）。以下示例显示了package install命令（及其输出），我们用来安装Hello World应用：spring-doc.cadn.net.cn

skipper:>package install --release-name helloworldpcf --package-name helloworld --package-version 1.0.0 --platform-name pws --properties spec.deploymentProperties.spring.cloud.deployer.cloudfoundry.route=helloworldpcf.cfapps.io
Released helloworldpcf. Now at version v1.

这spring.cloud.deployer.cloudfoundry.route=helloworldpcf.cfapps.iodeployment 属性，以便在部署此应用程序的不同版本时，它们具有相同的 HTTP 路由。spring-doc.cadn.net.cn

因为该 shell 选项的默认值是default`he `--platform-name pws，我们使用了命令选项。安装 Skipper 时，您可以在名称下注册一个平台default，但最佳做法是指定目标平台名称。spring-doc.cadn.net.cn

您可以使用release status命令，如以下示例所示（及其输出）：spring-doc.cadn.net.cn

skipper:>release status --release-name helloworldpcf
╔═══════════════╤════════════════════════════════════════════════╗
║Last Deployed  │Thu Jan 18 13:18:44 EST 2018                    ║

║               │[helloworldpcf-helloworld-v1], State = [partial]║
╚═══════════════╧════════════════════════════════════════════════╝

最终，平台状态显示：All applications have been successfully deployed.spring-doc.cadn.net.cn

这DEPLOYEDstatus 表示 Skipper 已告知平台进行部署。 Skipper 不跟踪“部署”或“删除”的中间状态。平台状态提供更细粒度的状态信息。

这cf apps命令现在具有此已部署应用程序的新列表，如以下示例所示（及其输出）：spring-doc.cadn.net.cn

$ cf apps
Getting apps in org scdf-ci / space space-mark as [email protected]...
OK

name                          requested state   instances   memory   disk   urls
helloworldpcf-helloworld-v1   started           1/1         1G       1G     helloworldpcf.cfapps.io

您现在可以卷曲greetingendpoint 和about端点，如以下示例所示：spring-doc.cadn.net.cn

$ curl https://helloworldpcf.cfapps.io/greeting
Hello World!
$ curl https://helloworldpcf.cfapps.io/about
Hello World v1.0.0.RELEASE

应用程序的名称基于<release-name>-<package-name>-v<incrementing-counter>公约。spring-doc.cadn.net.cn

另请注意，我们为此应用程序指定了与应用程序名称不同的路由。部署属性spring.cloud.deployer.cloudfoundry.route设置为在部署此应用程序的不同版本时不会更改的内容 - 在本例中，helloworldpcf.cfapps.io.spring-doc.cadn.net.cn

该软件包提供了一种模板化应用程序版本、应用程序属性和部署属性的方法，这些属性用于将应用程序部署到 Cloud Foundry。这manifest get命令显示传递给 Spring Cloud Deployer 库的最终 YAML 文件，如以下示例所示（及其输出）：spring-doc.cadn.net.cn

skipper:>manifest get --release-name helloworldpcf

---
# Source: helloworld.yml
apiVersion: skipper.spring.io/v1
kind: SpringCloudDeployerApplication
metadata:
  name: helloworld
  type: demo
spec:
  resource: maven://org.springframework.cloud.samples:spring-cloud-skipper-samples-helloworld:1.0.0.RELEASE
  applicationProperties:
  deploymentProperties:
    spring.cloud.deployer.cloudfoundry.route: helloworldpcf.cfapps.io

清单格式的灵感来自 Kubernetes 资源文件格式。通过查看清单，您可以看到在最终推送到 Cloud Foundry 之前使用了哪些 Maven 工件以及设置了哪些属性。 Skipper 的未来版本将使用元数据值来支持基于这些值搜索版本。spring-doc.cadn.net.cn

由于为--properties参数，您还可以在安装或升级时指定 YAML 文件的位置。在下一个示例中，我们使用一个名为helloworld-upgrade.yml，以更新版本。此应用程序包含一个 Spring Boot@ConfigurationProperty叫helloworld.greeting，因此我们将其与标准 Spring Boot 属性一起设置：endpoints.sensitive=false. 我们还将内存从默认的 2G 提高到 1G。的内容helloworld-upgrade.yml文件如下：spring-doc.cadn.net.cn

spec:
  applicationProperties:
    endpoints.sensitive: false
    helloworld.greeting: yo
  deploymentProperties:
    spring.cloud.deployer.cloudfoundry.route: helloworldpcf.cfapps.io
    spring.cloud.deployer.memory: 2048m

现在，您可以运行release upgrade命令，如以下示例所示（及其输出）：spring-doc.cadn.net.cn

skipper:>release upgrade --release-name helloworldpcf --package-name helloworld --package-version 1.0.0 --file /home/mpollack/helloworld-upgrade.yml
helloworldpcf has been upgraded.  Now at version v2.

前面的示例启动hello world应用程序的另一个实例，Skipper确定何时可以停止上一个实例的实例。如果未指定--package-version，它会选择最新版本的helloworld包。您无需指定--platform-name，因为它始终是部署当前应用程序的位置。spring-doc.cadn.net.cn

以下示例显示了cf apps命令及其输出：spring-doc.cadn.net.cn

$ cf apps
Getting apps in org scdf-ci / space space-mark as [email protected]...
OK

name                          requested state   instances   memory   disk   urls
helloworldpcf-helloworld-v1   started           1/1         1G       1G     helloworldpcf.cfapps.io
helloworldpcf-helloworld-v2   stopped           0/1         2G       1G     helloworldpcf.cfapps.io

以下示例显示了cf routes命令及其输出：spring-doc.cadn.net.cn

$ cf routes
Getting routes for org scdf-ci / space space-mark as [email protected] ...

space        host                          domain      port   path   type   apps                                                      service
space-mark   helloworldpcf                 cfapps.io                        helloworldpcf-helloworld-v1,helloworldpcf-helloworld-v2

此时，Skipper 正在检查新应用程序的运行状况。默认运行状况检查应用程序的 HTTP 端口是否打开。 Skipper 中有一个自定义功能，会影响运行状况检查的执行方式。这spring.cloud.skipper.server.strategies.healthcheck.timeoutInMillis属性是升级过程等待正常应用的最长时间。默认值为 5 分钟。如果 Skipper 在该时间内不正常，则部署失败。这spring.cloud.skipper.server.strategies.healthcheck.sleepInMillis属性是两次健康检查之间的睡眠时间。spring-doc.cadn.net.cn

当前的升级策略非常简单：如果新应用程序正常，则删除旧应用程序。没有滚动升级选项，部署所有新应用，检查运行状况，然后删除以前的版本。计划在未来的版本中提供更灵活的升级策略。spring-doc.cadn.net.cn

您现在可以卷曲greetingendpoint 和about端点，如以下示例所示：spring-doc.cadn.net.cn

$ curl https://helloworldpcf.cfapps.io/greeting
yo
$ curl https://helloworldpcf.cfapps.io/about

更典型的升级过程不是更改应用程序属性，而是更改应用程序的版本，因为代码已更改。在下面的示例中，我们现在升级版本以使用新的 Maven 工件 1.0.1 版，该工件也对应于 1.0.1 版的helloworld船长套餐。在这种情况下，除了路由之外，我们不会添加任何其他属性。以下示例显示了release upgrade命令（及其更新）来部署版本 1.0.1：spring-doc.cadn.net.cn

skipper:>release upgrade --release-name helloworldpcf --package-name helloworld --package-version 1.0.1 --properties spec.deploymentProperties.spring.cloud.deployer.cloudfoundry.route=helloworldpcf.cfapps.io
helloworldpcf has been upgraded.  Now at version v3.

请注意，当前版本的属性值，例如使用 2G 或问候语是yo不会结转。未来的版本将引入--reuse-properties命令，该命令将当前版本属性传递到下一个要制作的版本。您可以使用status命令，如以下示例所示（及其输出）：spring-doc.cadn.net.cn

skipper:>release status --release-name helloworldpcf

现在我们可以安装 Hello World 应用程序（特别是基于 Docker 的工件），如下所示：spring-doc.cadn.net.cn

skipper:>package install --release-name helloworldk8s --package-name helloworld-docker --package-version 1.0.0 --platform-name minikube --properties spec.deploymentProperties.spring.cloud.deployer.kubernetes.createNodePort=32123
Released helloworldk8s. Now at version v1.

我们使用--platform-name minikubecommand 选项，因为该 shell 选项的默认值是default. 您可以在defaultname 时，但最佳做法是指定目标平台名称。spring-doc.cadn.net.cn

您可以使用release status命令，如下所示：spring-doc.cadn.net.cn

skipper:>release status --release-name helloworldk8s
╔═══════════════╤══════════════════════════════════════════════════════════════════════════════════════════════════╗

╚═══════════════╧══════════════════════════════════════════════════════════════════════════════════════════════════╝

最终，平台状态显示：All applications have been successfully deployed.spring-doc.cadn.net.cn

请注意，DEPLOYEDstatus 表示 Skipper 已告知平台进行部署。 Skipper 不跟踪中间状态（“部署”或“删除”）。spring-doc.cadn.net.cn

一个kubectl pods命令现在显示此已部署应用程序的新列表，如下所示：spring-doc.cadn.net.cn

$ kubectl get pods
NAME                                       READY     STATUS    RESTARTS   AGE
helloworldk8s-helloworld-docker-v1-g8j39   0/1       Running   0          37s

$ kubectl get service

要在 minikube 上获取此应用程序的 URL，请使用minikube service命令，如下所示：spring-doc.cadn.net.cn

$ minikube service --url helloworldk8s-helloworld-docker-v1
https://192.168.99.100:32123

您现在可以卷曲greetingendpoint 和about端点，如以下示例所示：spring-doc.cadn.net.cn

$ curl https://192.168.99.100:32123/greeting
Hello World!
$ curl https://192.168.99.100:32123/about
Hello World v1.0.0.RELEASE

应用程序的名称基于以下约定：<release-name>-<package-name>-v<incrementing-counter>. 未来的版本将更改此约定以正确处理路由。spring-doc.cadn.net.cn

该包提供了一种模板化应用程序版本、应用程序属性和部署属性的方法，这些属性用于将应用程序部署到 Kubernetes。这manifest get命令显示最终的 YAML 文件，该文件被传递给 Spring Cloud Deployer 库，如以下示例所示（及其输出）：spring-doc.cadn.net.cn

skipper:>manifest get --release-name helloworldk8s

---
# Source: template.yml
apiVersion: skipper.spring.io/v1
kind: SpringCloudDeployerApplication
metadata:
  name: helloworld-docker
spec:
  resource: docker:springcloud/spring-cloud-skipper-samples-helloworld:1.0.0.RELEASE
  applicationProperties:
  deploymentProperties:
    spring.cloud.deployer.kubernetes.createNodePort: 32123

的格式灵感来自 Kubernetes 资源文件格式。通过查看清单，您可以看到在最终推送到 Kubernetes 之前使用了哪些 Docker 镜像以及设置了哪些属性。 Skipper 的未来版本将使用元数据值来支持基于这些值搜索版本。spring-doc.cadn.net.cn

由于为--properties参数，您还可以在安装或升级时指定 YAML 文件的位置。我们在更新版本时使用 YAML 文件。此应用程序包含一个 Spring Boot@ConfigurationProperty叫helloworld.greeting，因此我们将其与标准 Spring Boot 属性一起设置：endpoints.sensitive=false. 我们还将内存从默认的 1G 降低到 768m。以下列表显示了所有设置：spring-doc.cadn.net.cn

spec:
  applicationProperties:
    endpoints.sensitive: false
    helloworld.greeting: yo
  deploymentProperties:
    spring.cloud.deployer.kubernetes.createNodePort: 32124
    spring.cloud.deployer.memory: 768m

以下示例显示了release upgrade命令及其输出：spring-doc.cadn.net.cn

skipper:>release upgrade --release-name helloworldk8s --package-name helloworld-docker --package-version 1.0.0 --file /home/mpollack/helloworld-upgrade-k8s.yml
helloworldk8s has been upgraded.  Now at version v2.

上述命令启动 hello world 应用程序的另一个实例。如果您未指定--package-version，它会选择最新版本的helloworld-docker包。您无需指定--platform-name因为它始终是部署当前应用程序的位置。spring-doc.cadn.net.cn

以下示例显示了kubectl get all命令及其输出：spring-doc.cadn.net.cn

$ kubectl get all

此时，Skipper 正在查看启动应用程序的运行状况终结点是否正常。这spring.cloud.skipper.server.strategies.healthcheck.timeoutInMillis属性设置升级过程等待正常应用的最长时间。默认值为 5 分钟。如果 Skipper 在该时间内不正常，则部署失败。这spring.cloud.skipper.server.strategies.healthcheck.sleepInMillis属性设置运行状况检查之间的睡眠时间。spring-doc.cadn.net.cn

当前的升级策略很简单：如果新应用程序正常，则删除旧应用程序。没有滚动升级选项。部署并检查所有新应用的运行状况。然后删除所有以前的版本。未来的版本将具有更灵活的升级策略，以及引入 Spring Cloud State Machine 项目来编排更新过程。spring-doc.cadn.net.cn

您现在可以卷曲greetingendpoint 和about端点，如下所示：spring-doc.cadn.net.cn

$ curl https://192.168.99.100:32124/greeting
yo
$ curl https://192.168.99.100:32124/about

更典型的升级过程不是更改应用程序属性，而是更改应用程序的版本，因为代码已更改。我们现在可以升级该版本以使用新的 Docker 工件 1.0.1 版，该工件也对应于 1.0.1 版的helloworld船长套餐。在下面的示例中，我们不会添加除NodePort:spring-doc.cadn.net.cn

skipper:>release upgrade --release-name helloworldk8s --package-name helloworld-docker --package-version 1.0.1 --properties spec.deploymentProperties.spring.cloud.deployer.kubernetes.createNodePort=32125
Released helloworldk8s. Now at version v3.
