1、开启Docker daemon服务远程访问
修改docker.service配置
[root@localhost docker.registry:5000]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.3 (Maipo)vim /lib/systemd/system/docker.service
不同系统路径可能会有差别，找到
ExecStart=/usr/bin/dockerd
添加 -H tcp://0.0.0.0:5200 -H unix:///var/run/docker.sock
重启docker
sudo service docker start验证
[root@localhost ~]# docker -H 172.16.1.146:5200 images

此处根据dockerfile生成镜像，
pom.xml中添加插件。
<!-- 生成时间戳 -->
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.9.1</version>
<executions>

</plugin>
<!-- 打包生成镜像、push镜像到私有镜像中心 -->
<plugin>

</goals>
</execution>
</executions>
<configuration>
<!-- 私有镜像中心的用户名 -->

<!-- 172.16.1.146:8888：私有镜像中心地址； wondertek/${project.artifactId}：镜像名称-->
<repository>172.16.1.146:8888/wondertek/${project.artifactId}</repository>
<!-- 镜像版本号 -->
<tag>${project.version}-${current.time}</tag>
<buildArgs>
<!-- 参数，提供给dockerfile使用 -->
<JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
<JAR_FILE>target/docker-test-1.0.0.jar</JAR_FILE>
</buildArgs>
</configuration>
</plugin>3、dockerfile配置
官网说明：https://docs.docker.com/develop/develop-images/dockerfile_best-practices/
# 拉取基础镜像
FROM hub.c.163.com/library/java:8-jdk
# 镜像的作者
MAINTAINER [email protected]
#挂载目录，通过 VOLUME 指令创建的挂载点，无法指定主机上对应的目录，是自动生成的
VOLUME ["/data1","/data2"]
RUN ["mkdir", "-p", "/app"]
#结合maven插件dockerfile-maven-plugin的打包使用
ARG JAR_FILE
ADD ${JAR_FILE} /app/app.jar
#为后面的 RUN, CMD, ENTRYPOINT, ADD 或 COPY 指令设置镜像中的当前工作目录。
#WORKDIR /usr/local/docker/test
#拷贝当前目录文件到容器/app
#COPY . /app
#与 COPY 类似，从 build context 复制文件到镜像。不同的是，如果 src 是归档文件（tar, zip, tgz, xz 等），文件会被自动解压到 dest。
#ADD src dest
#设置环境变量，环境变量可被后面的指令使用
ENV EVN_SET_TEST "WELCOME TO DOCKERFILE CONTAINER！'
##################
# RUN、CDM、ENTRYPOINT 命令都包含两种格式：Shell 格式和 Exec 格式
# CMD还可以放在ENTRYPOINT后，为其传递参数。
##### shell 格式：######
## 底层会调用 /bin/sh -c <command>
# 在容器中运行指定的命令
RUN echo $EVN_SET_TEST
# 容器启动命令 只有最后一个生效，CMD 可以被 docker run 之后的参数替换。
#只有最后一个生效
CMD echo "CMD Hello world"
#配置容器启动时运行的命令
ENTRYPOINT echo "ENTRYPOINT Hello, $EVN_SET_TEST"
###### Exec 格式： #####
## 当指令执行时，会直接调用 <command>，不会被 shell 解析
# ENTRYPOINT ["/bin/echo", "Hello, $EVN_SET_TEST"]
# 正确写法应该为：
# ENTRYPOINT ["/bin/sh", "-c", "echo Hello, $EVN_SET_TEST"]
# 为Exec 格式的ENTRYPOINT传递参数，结果输出Hello, $EVN_SET_TEST dockerfile world
# CMD ["dockerfile world"]
#只有最后一个生效
ENTRYPOINT ["java","-jar","/app/app.jar"]
#表示哪个端口提供服务的提示，宿主机如果要访问，需要结合-P参数联合使用。
EXPOSE 80804、build publish镜像
配置远程docker环境变量
export DOCKER_HOST=tcp://172.16.1.146:5200windows直接在环境变量中添加。
mvn命令执行
build镜像：
mvn clean package dockerfile:build -DskipTests发布到镜像中心，注意，该命令不会build镜像。
mvn dockerfile:push配置中 build 和 publish 都绑定在install周期上。
如果不想触发相关流程，可以添加相关例外参数。
mvn clean install -Ddockerfile.skip| 命令 | 说明 |
|---|---|
| dockerfile.skip | Disables the entire dockerfile plugin; all goals become no-ops. |
| dockerfile.build.skip | Disables the build goal; it becomes a no-op. |
| dockerfile.tag.skip | Disables the tag goal; it becomes a no-op. |
| dockerfile.push.skip | Disables the push goal; it becomes a no-op. |
