前言

今天开始第四篇, 主要介绍下几个微服务的部署. 介绍2种方法, 一种是分步的, 构建jar、打镜像、传到镜像库、K8S部署；另一种直接通过Maven + Farbic8 一气呵成。

微服务部署

微服务部署这里介绍2种方式:

Maven, Docker build, K8S 部署
Maven Farbic8 直接部署到K8S

如果已有的maven编译等方式不希望改动, 且希望build和deploy分离, 则推荐用第一种方式;

如果希望更快速高效, 全新的代码直接上K8S, 则推荐第二种方式.

第二种 Maven Farbic8 直接部署到K8S 部署方式的一些优点:

参数, 变量, 配置可以全局应用. 如: 服务名....
会检测actuator, 并自动添加K8S Liveness和Readiness Probe
可以添加icon到容器平台, 展示更友好;
可以根据编译好的版本号等自动打镜像tag
自动登录K8S或OpenShift平台;
自动部署

Maven, Docker build, K8S 部署

细节就不介绍了, 说一下简要步骤.

Maven 构建为jar包
写个Dockerfile, jar包通过docker build方式构建为docker镜像;
将构建好的镜像打好tag, 如snapshot-191114-111831-0702, push到镜像仓库.
K8S 创建Deployment和Service和Ingress(或Route), 并引用镜像仓库中新的镜像tag, 并启动.

Maven Farbic8 直接部署到K8S

要部署Spring启动服务，使用Maven构建项目，使用openshift配置文件的fabric8:deploy target将构建的镜像部署到openshift。为了方便起见，在项目的根目录下提供了一个聚合器pom文件，它将同一个Maven构建委托给所有6个配置的模块.

$ mvn clean fabric8:deploy -Popenshift

以上是RedHat官方的做法: 用fabric8 maven插件, 直接将源代码打成镜像, 并推送到镜像仓库. 另外会直接访问OpenShift去创建相关的 Deployment, Service, Route等.

Farbic8 详细解释

maven Farbic8:deploy 举一个 airports 的构建例子, 具体构建日志如下:

运行于 K8S mode: [INFO] F8: Running in Kubernetes mode
generator spring-boot. [INFO] F8: Running generator spring-boot
使用Docker Image: registry.access.redhat.com/redhat-openjdk-18/openjdk18-openshift作为基础镜像和构建镜像. [INFO] F8: spring-boot: Using Docker image registry.access.redhat.com/redhat-openjdk-18/openjdk18-openshift as base / builder
使用Airports\src\main\fabric8 resource templates, 里边包括deployment.yml和svc.yml. 用于创建OpenShift Deployment和Service. [INFO] F8: using resource templates from D:\Projects\spring-boot-msa-ocp\Airports\src\main\fabric8
由于使用了spring-boot的spring-boot-starter-actuator, 所以会自动加 Readiness Probe. INFO] F8: spring-boot-health-check: Adding readiness probe on port 8080, path='/health', scheme='HTTP', with initial delay 10 seconds
同理, 也加了Liveness Probe: [INFO] F8: spring-boot-health-check: Adding liveness probe on port 8080, path='/health', scheme='HTTP', with initial delay 180 seconds
还能自动加icon到Deployment和Service: [INFO] F8: f8-icon: Adding icon for deployment [INFO] F8: f8-icon: Adding icon for service
找有没有OpenShift的 DeploymentConfig 的yaml文件, 没找到.
找有没有K8S的Deployment 的yaml文件, 没找到.
然后就可以常规的编译, 生成spring-boot jar包: airports-1.0-SNAPSHOT.jar 和 airports-1.0-SNAPSHOT-exec.jar
把airports-1.0-SNAPSHOT-exec.jar拷贝到target\docker\lambdaair\airports\snapshot-191114-101239-0722\build\maven目录: [INFO] Copying files to D:\Projects\spring-boot-msa-ocp\Airports\target\docker\lambdaair\airports\snapshot-191114-101239-0722\build\maven
然后用Dockerfile 执行docker build, 其实很简单的: FROM registry.access.redhat.com/redhat-openjdk-18/openjdk18-openshift ENV JAVA_APP_DIR=/deployments EXPOSE 8080 8778 9779 COPY maven /deployments/
然后打上标签: latest
接下来连接K8S或OpenShift控制台. (我用的是OpenShift 4.2, farbic8好像不兼容, 认成了K8S了. K8S创建的是Deployment, OpenShift创建的是DeploymentConfig).
使用Project: lambdaair
创建SVC: [INFO] Updated Service: \target\fabric8\applyJson\lambdaair\service-airports.json
创建Deployment: [INFO] Updated Deployment: \target\fabric8\applyJson\lambdaair\deployment-airports.json. 这时候已经启动了Pod.
完成.

一旦所有服务都被构建和部署，应该总共有8个运行的pod，包括之前的2个Zipkin pod，以及6个服务中的每一个新的pod:

$ oc get pods
NAME                       READY     STATUS      RESTARTS   AGE

小结

presentation 服务还创建一个Route。再次列出OpenShift项目中的路由:

$ oc get routes
NAME           HOST/PORT                                    PATH      SERVICES       PORT      TERMINATION   WILDCARD
presentation   presentation-lambdaair.ocp.xxx.example.com             presentation   8080                    None
zipkin         zipkin-lambdaair.ocp.xxx.example.com                   zipkin         9411                    None

使用路由的URL从浏览器访问HTML应用程序，并验证它是否出现.
