配置JDK11

参考

微服务Docker镜像打包

父项目（xdclass-cloud）添加springboot版本依赖

 <properties>
        <java.version>11</java.version>
        <maven.compiler.source>11</maven.compiler.source>
        <maven.compiler.target>11</maven.compiler.target>
        <spring.boot.version>2.3.3.RELEASE</spring.boot.version>
  </properties>

每个子模块项目添加依赖（xdclass-api-gateway）

//配置文件增加
    <properties>
        <docker.image.prefix>xdclass-cloud</docker.image.prefix>
    </properties>


<build>
        <finalName>alibaba-cloud-gateway</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
		<executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <fork>true</fork>
                    <addResources>true</addResources>
                </configuration>
            </plugin>

            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>dockerfile-maven-plugin</artifactId>
                <version>1.4.10</version>
                <configuration>
                    <repository>${docker.image.prefix}/${project.artifactId}</repository>
                    <buildArgs>
                        <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
                    </buildArgs>
                </configuration>
            </plugin>
        </plugins>
    </build>

• Spotify 的 docker-maven-plugin 插件是用maven插件方式构建docker镜像的。

${project.build.finalName} 产出物名称，缺省为${project.artifactId}-${project.version}

在每个子项目（xdclass-api-gateway）的根目录下创建文件Dockerfile

FROM  adoptopenjdk/openjdk11:ubi
VOLUME /tmp
ARG JAR_FILE
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-jar","/app.jar"]

构建镜像( 去到子模块pom文件下)执行命令

mvn install -Dmaven.test.skip=true dockerfile:build

等待执行成功

本地镜像上传阿里云私有仓库

1. 登录阿里云Docker Registry
sudo docker login --username=soulboy1990116 registry.cn-shanghai.aliyuncs.com


2. 将镜像推送到Registry
本地镜像打标签
$ sudo docker tag [ImageId] registry.cn-shanghai.aliyuncs.com/abc1024/cloud-gateway:[镜像版本号]
$ sudo docker tag a8722afafb45 registry.cn-shanghai.aliyuncs.com/abc1024/cloud-gateway:v1.0

将本地镜像推送至阿里云私有仓库
$ sudo docker push registry.cn-shanghai.aliyuncs.com/abc1024/cloud-gateway:[镜像版本号]
$ sudo docker push registry.cn-shanghai.aliyuncs.com/abc1024/cloud-gateway:v1.0

从阿里云私有仓库拉去镜像到阿里云ECS部署服务

1. 从Registry中拉取镜像
sudo docker pull registry.cn-shanghai.aliyuncs.com/abc1024/cloud-gateway:v1.0

2.网关容器启动
docker run  --name xdclass-gateway -d -p 8888:8888 [镜像id]
