将微服务运行在Docker上

我们需要把之前的微服务部署到docker上去,之前的微服务搭建可以翻看我博客的【Spring Cloud 基础设施搭建系列】

我对之前的一些配置进行了抽取,抽取了common的配置,并且放置到配置中心,还解决了Admin Server中无法获取Config Server的健康状态,解决方法是在Config Server的security配置中过滤掉"/actuator/health"端点。

这次我们主要讲一下如何使用Maven插件构建Docker镜像,如果对Docker不熟悉的可以先去看看Docker的基础使用。

使用Maven插件构建Docker镜像

Maven是一个强大的项目管理与构建工具。如果可以使用Maven构建Docker镜像,工作就能得到进一步的简化。

我们以cloud-eureka为例子,演示一下如何使用Maven插件构建Docker镜像

  1. 首先我们需要在parent pom文件中加入maven的插件。
    我们这里使用的是spotify的docker插件。
<plugin>
    <groupId>com.spotifygroupId>
    <artifactId>docker-maven-pluginartifactId>
    <version>0.4.13version>
    <configuration>
        <forceTags>trueforceTags>
        <imageName>spring-cloud-demo/${project.artifactId}:${project.version}imageName>
        <baseImage>javabaseImage>
        <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]entryPoint>
        <resources>
            <resource>
                <targetPath>/targetPath>
                <directory>${project.build.directory}directory>
                <include>${project.build.finalName}.jarinclude>
            resource>
        resources>
    configuration>
plugin>

简要说明一下插件的配置:

  • imageName:用于指定镜像名称,其中spring-cloud-demo是仓库名称,${project.artifactId}是镜像名称, ${project.version}是标签名称。
  • baselmage:用于指定基础镜像,类似于Dockerfile中的FROM指令。
  • entrypoint:类似于Dockerfile的ENTRYPOINT指令。
  • resources.resource.directory:用于指定需要复制的根目录,${project.build.directory}
    表示target目录。
  • resources.resource.include:用于指定需要复制的文件。${project.build.finalName}.jar指的是打包后的jar包文件。

${project.build.finalName},${project.build.directory}对应的值到底是什么呢?

我们可以右键我们的cloud-eureka项目,找到Maven-> Show Effective POM,然后搜索finalName就可以找到。

【Spring Cloud 基础设施搭建系列】Spring Cloud Demo项目 将微服务运行在Docker上_第2张图片

【Spring Cloud 基础设施搭建系列】Spring Cloud Demo项目 将微服务运行在Docker上_第3张图片

其实${project.build.finalName}默认值就是为${project.artifactId}-${project.version}

我们搜directory就可以找到${project.build.directory}

【Spring Cloud 基础设施搭建系列】Spring Cloud Demo项目 将微服务运行在Docker上_第4张图片

其实${project.build.directory}是构建目录,默认为target目录

Maven内置变量说明:

  • ${basedir} 项目根目录
  • ${project.build.directory} 构建目录,缺省为target
  • ${project.build.outputDirectory} 构建过程输出目录,缺省为target/classes
  • ${project.build.finalName} 产出物名称,缺省为${project.artifactId}-${project.version}
  • ${project.packaging} 打包类型,缺省为jar
  • ${project.xxx} 当前pom文件的任意节点的内容

由以上日志可知,已成功构建了一个Docker镜像。

  1. 执行docker images命令,即可查看刚刚构建的镜像。
$ docker images
REPOSITORY                TAG                 IMAGE ID            CREATED             SIZE
cloud-demo/cloud-eureka   1.0                 2bddac8bfef7        10 minutes ago      687MB
  1. 启动以下镜像:
$ docker run -d -p 8888:8888 cloud-demo/cloud-eureka:1.0
9105eacca9aa7dc01d6285aef9571b1397c70040bdb691515fe2d3b9e2c66882
  1. 访问测试
    访问 http://Docker 宿主机IP:8888,能够看到Eureka Server的首页。

我们这里访问 http://192.168.99.100:8888/

使用Maven插件读取Dockerfile进行构建

之前的示例直接在pom.xml中设置了一些构建的参数。很多场景下希望使用Dockerfile更精确、有可读性地构建镜像。

  1. 首先在/cloud-eureka/src/main/docker目录下,新建一个Dockerfile文件
FROM java:8
VOLUME /tmp
ADD cloud-eureka-1.0.jar app.jar
RUN bash -c 'touch /app.jar'
EXPOSE 8888
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

VOLUME 指定挂载点

  • 该指令使容器中的一个目录具有持久化存储的功能,该目录可被容器本身使用,也可共享给其他容器。当容器中的应用有持久化数据的需求时可以在Dockerfile中使用该指令。

ADD复制文件

  • ADD指令用于复制文件

EXPOSE声明暴露的端口

  • EXPOSE指令用于声明在运行时容器提供服务的端口
  1. 修改pom.xml
<plugin>
        <groupId>com.spotifygroupId>
        <artifactId>docker-maven-pluginartifactId>
        <version>0.4.13version>
        <configuration>
            <imageName>cloud-demo/${project.artifactId}:${project.version}imageName>
            <dockerDirectory>${project.basedir}/src/main/dockerdockerDirectory>
            <resources>
                <resource>
                    <targetPath>/targetPath>
                    <directory>${project.build.directory}directory>
                    <include>${project.build.finalName}.jarinclude>
                resource>
            resources>
        configuration>
    plugin>

可以看到,不再指定baselImage和entrypoint,而是使用dockerDirectory指定Dockerfile所在的路径。这样,就可以使用Dockerfile构建Docker镜像了。

将插件绑定在某个phase执行

很多场景下,有这样的需求,执行例如mvn clean package时,插件就自动为构建 Docker镜像。要想实现这点,只须将插件的goal绑定在某个phase即可。

phase和goal可以这样理解:maven命令格式是:mvn phase:goal,例如mvn package docker
:build。那么,package和docker都是phase,build则是goal。示例:

<plugin>
    <groupId>com.spotifygroupId>
    <artifactId>docker-maven-pluginartifactId>
    <version>0.4.13version>
    <executions>
        <execution>
            <id>build-imageid>
            <phase>packagephase>
            <goals>
                <goal>buildgoal>
            goals>
        execution>
    executions>
    <configuration>
        <imageName>cloud-demo/${project.artifactId}:${project.version}imageName>
        <dockerDirectory>${project.basedir}/src/main/dockerdockerDirectory>
        <resources>
            <resource>
                <targetPath>/targetPath>
                <directory>${project.build.directory}directory>
                <include>${project.build.finalName}.jarinclude>
            resource>
        resources>
    configuration>
plugin>

由配置可知,只须添加如下配置:

<executions>
    <execution>
        <id>build-imageid>
        <phase>packagephase>
        <goals>
            <goal>buildgoal>
        goals>
    execution>
executions>

就可将插件绑定在package这个phase上。也就是说,用户只须执行mvn package,就会自动执行mvn docker:build。当然,读者也可按照需求,将插件绑定到其他的phase。

然后我们执行如下命令就可以进行构建了。
