Docker Desktop安装及配置

1. 本地安装docker，本地是windows环境安装的是Docker Desktop，安装参考docker desktop 安装部署及使用 - 我是一只搬砖狗 - 博客园 (cnblogs.com) (opens new window)
2. 配置环境，修改 ~/.docker/config.json 配置文件

{
    "auths": {
        "registry.cn-hangzhou.aliyuncs.com": {}
    },
    "credsStore": "wincred"
}

将以上配置的 "credsStore":"wincred" 去掉，这样在登陆后会将认证保存在此文件中，不然 docker-maven-plugin 获取不到认证信息，导致推送镜像失败 3. 执行以下命令并输入密码，保存阿里云的认证信息

docker login --username=wuzhiyong1990 registry.cn-hangzhou.aliyuncs.com

本地编译

1. docker-maven-plugin插件配置

<build>
	<plugins>
		<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
		</plugin>

		<plugin>
			<groupId>com.spotify</groupId>
			<artifactId>docker-maven-plugin</artifactId>
<!--                <version>1.0.0</version>-->
			<configuration>
<!--                    参考https://github.com/zq2599/blog_demos/blob/master/mavendockerplugindemo/pom_4_ali_server.xml-->
<!--                    <imageName>${docker.image.prefix}/${project.artifactId}</imageName>-->
				<imageName>registry.cn-hangzhou.aliyuncs.com/wuzhiyong/wx_mp</imageName>
				<dockerDirectory>src/main/docker</dockerDirectory>
				<resources>
					<resource>
						<targetPath>/</targetPath>
						<directory>${project.build.directory}</directory>
						<include>${project.build.finalName}.jar</include>
					</resource>
				</resources>
				<serverId>docker-aliyun</serverId>
				<registryUrl>registry.cn-hangzhou.aliyuncs.com</registryUrl>
				<pushImage>true</pushImage>
			</configuration>
		</plugin>
	</plugins>
</build>

2. Dockerfile

FROM openjdk:8-jdk-alpine  
VOLUME /tmp  
ADD weixin-java-mp-demo-1.0.0-SNAPSHOT.jar app.jar  
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

3. maven里加入docker-aliyun的配置，D:\Programs\apache-maven-3.6.0\conf\settings.xml加入以下

<servers>
	<server> 
	  <id>docker-aliyun</id>
	  <username>wuzhiyong1990</username>
	  <password>xxxxxx</password>
	</server>
  </servers>

4. 执行mvn package -DskipTests docker:build，编译后会同步推送到阿里云的镜像仓库
