win10 idea springboot上传镜像到远程docker服务器

1. 开启2375端口，供外部访问docker

vim /usr/lib/systemd/system/docker.service
修改ExecStart为下面一行内容
#ExecStart=/usr/bin/dockerd -H unix://
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

systemctl daemon-reload // 1，加载docker守护线程
systemctl restart docker // 2，重启docker

测试端口是否成功 curl 127.0.0.1:2375/info

在win10客户端添加环境变量

添加dos下mvn命令的执行

直接在Path属性后面添加一条当前Maven的文件地址加上\bin

2. 使用docker-maven-plugin插件上传镜像到docker服务器

<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.</version>
                <configuration>
                    <imageName>${project.name}:${project.version}</imageName>
                    <dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory>
                    <dockerHost>http://192.168.1.10:2375</dockerHost>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>
        </plugins>
    </build>

3. 在src/main下面新建文件夹docker

添加文件Dockerfile

FROM daocloud.io/library/java:8u40-b22  #这里是巨坑，下载慢的话一定要关闭从新下载
VOLUME /tmp
ADD gexin-docker-demo-1.0-SNAPSHOT.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]

执行命令  mvn clean package docker:build

执行成功出现如下截图内容

报错如下：

1. No plugin found for prefix 'docker' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (F:\repo), nexus-aliyun (http://maven.aliyun.com/nexus/content/groups/public)] -> [Help 1]

解决办法：在maven的conf/setting.xml中要加入

<pluginGroups>
    <!-- pluginGroup
     | Specifies a further group identifier to use for plugin lookup.
    <pluginGroup>com.your.plugins</pluginGroup>
    -->
    <pluginGroup>com.spotify</pluginGroup>
  </pluginGroups>

<mirrors>
<!-- mirror
| Specifies a repository mirror site to use instead of a given repository. The repository that
| this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
| for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
|
<mirror>
<id>mirrorId</id>
<mirrorOf>repositoryId</mirrorOf>
<name>Human Readable Name for this Mirror.</name>
<url>http://my.repository.com/repo/path</url>
</mirror>
-->
<mirror>
    <id>nexus-aliyun</id>
    <mirrorOf>*</mirrorOf>
    <name>Nexus aliyun</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>
</mirrors>

再次执行mvn clean package docker:build

4. 登录虚拟机可以看到

[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

在浏览器查看结果 http://192.168.1.10:8091/

总结：

1. 选择使用docker和dockerfile执行很重要

2. FROM 选择jdk很重要，可能造成下载过慢或者找不到包
