Docker使用Dockerfile构建微服务发现镜像实例

我们以微服务发现测试demo为例，打包并构建微服务发现镜像。实现docker镜像构建需要准备docker环境，这里就不在赘述了。通过docker方式可以快速实现微服务的发布和部署，使得开发和部署不再复杂而繁琐。单体应用的整体维护容易引入bug而微服务只需要对存在bug的服务模块进行修复不影响其它模块的运行，虽然很多情况下考虑微服务会带来维护成本的增加，但是在开发运维一体化的实践过程中，“开发即运维

Maven打出可运行的jar包

找到项目主路径使用mvn命令打包：

mvn install

打包后可以在target下找到相应的jar包：

我们在centos中创建一个microservcice目录并上传jar包：

mkdir microservcice
cd microservcice
rz  microservice-discovery-eureka-0.0.1-SNAPSHOT.jar

Dockerfile文件的创建和编辑

在microservcice路径下使用vi编辑Dockerfile并创建文件：

vi Dockerfile

Dockerfile的内容如下：

# 基于哪个镜像
FROM java:8

# 将本地文件夹挂载到当前容器
VOLUME /tmp

# 拷贝文件到容器，也可以直接写成ADD microservice-discovery-eureka-0.0.1-SNAPSHOT.jar /app.jar
ADD microservice-discovery-eureka-0.0.1-SNAPSHOT.jar app.jar
RUN bash -c 'touch /app.jar'

# 开放8761端口
EXPOSE 8761

# 配置容器启动后执行的命令
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

注：为使镜像文件不至于过大所以基础镜像不采用任何Unix镜像而直接用就JDK镜像。

Docker构建和运行微服务发现

镜像构建命令：docker build -t boonyadocker/centos-microservice-discovery-eureka .

[root@mysqlserver microservice]# docker build -t boonyadocker/centos-microservice-discovery-eureka .

深入理解 Mocha 测试框架：从零实现一个 Mocha

前言什么是自动化测试自动化测试在很多团队中都是Devops环节中很难执行起来的一个环节，主要原因在于测试代码的编写工作很难抽象，99%的场景都需要和业务强绑定，而且写测试代码的编写工作量往往比编写实际业务代码的工作量更多。在一些很多业务场景中投入产出比很低，适合写自动化测试的应该是那些中长期业务以及一些诸如组件一样的基础库。自动化测试是个比较大的概念，其中分类也比较多，比如单元测试，端对端测试，集
