微服务 Docker 镜像打包

父项目（xdclass-cloud）添加 SpringBoot 版本依赖

1 <properties>
2        <java.version>11</java.version>
3        <maven.compiler.source>11</maven.compiler.source>

5        <spring.boot.version>2.3.3.RELEASE</spring.boot.version>
6  </properties>

每个子模块项目添加依赖（xdclass-api-gateway）

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

1${project.build.finalName} 产出物名称，缺省为${project.artifactId}-${project.version}

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

1FROM  adoptopenjdk/openjdk11:ubi
2VOLUME /tmp
3ARG JAR_FILE
4COPY ${JAR_FILE} app.jar
5ENTRYPOINT ["java","-jar","/app.jar"]

构建镜像( 去到子模块 pom 文件下)执行命令

1mvn 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

 11. 登录阿里云Docker Registry
 2sudo docker login --username=soulboy1990116 registry.cn-shanghai.aliyuncs.com
 3
 4
 52. 将镜像推送到Registry
 6本地镜像打标签
 7$ sudo docker tag [ImageId] registry.cn-shanghai.aliyuncs.com/abc1024/cloud-gateway:[镜像版本号]
 8$ sudo docker tag a8722afafb45 registry.cn-shanghai.aliyuncs.com/abc1024/cloud-gateway:v1.0

10将本地镜像推送至阿里云私有仓库
11$ sudo docker push registry.cn-shanghai.aliyuncs.com/abc1024/cloud-gateway:[镜像版本号]
12$ 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

11. 从Registry中拉取镜像
2sudo docker pull registry.cn-shanghai.aliyuncs.com/abc1024/cloud-gateway:v1.0
3
42.网关容器启动
5docker run  --name xdclass-gateway -d -p 8888:8888 [镜像id]
