DockerFile 文件详解、docker-maven-plugins的使用的使用

一、dockerFile的指令详解

1、举例

FROM java:8
MAINTAINER 12345@qq.com
# 指定零时文件路径，在主机下的路径
VOLUME /usr/local/docker/tmp
ADD cloud-docker-test-1.0.0.jar docker-test.jar
# 运行jar
RUN bash -c 'touch /docker-test.jar' ENTRYPOINT ["java","-jar","/docker-test.jar"]
EXPOSE 8881

2、jeecg-boot的某个配置

https://gitee.com/jeecg/jeecg-boot/blob/master/jeecg-server-cloud/jeecg-cloud-gateway/Dockerfile

FROM anapsix/alpine-java:8_server-jre_unlimited

MAINTAINER jeecgos@163.com

RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

RUN mkdir -p /jeecg-cloud-gateway

WORKDIR /jeecg-cloud-gateway

EXPOSE 9999

ADD ./target/jeecg-cloud-gateway-3.4.0.jar ./

CMD sleep 50;java -Dfile.encoding=utf-8 -Djava.security.egd=file:/dev/./urandom -jar jeecg-cloud-gateway-3.4.0.jar

二、docker-maven-plugins的使用

1、让docker可以远程访问、开放2375端口

修改docker.service文件

vim /lib/systemd/system/docker.service
1

修改前

ExecStart=/usr/bin/docker -H fd:// --containerd=/run/containerd/containerd.sock

修改后

ExecStart=/usr/bin/docker -H fd:// --containerd=/run/containerd/containerd.sock ‐H tcp://0.0.0.0:2375 ‐H unix:///var/run/docker.sock

• 开放端口

firewall-cmd --zone=public --add-port=2375/tcp --permanent
firewall-cmd --reload

2

2、刷新配置，重启服务

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

3、配置防火墙

systemctl stop firewalld (关闭防火墙)
systemctl disable firewalld (禁用防火墙，开机不会启动)

4、关闭防火墙

#编辑selinux/config文件
vi /etc/selinux/config
#SELINUX=enforcing改为disabled
SELINUX=disabled
#重启防火墙
systemctl restart firewalld # 重启防火墙
systemctl status firewalld #查看防火墙状态

5、项目中的使用

<plugin>
    <groupId>com.spotifygroupId>
    <artifactId>docker-maven-pluginartifactId>
    <version>1.0.0version>
    <configuration>
        <dockerHost>http://192.168.11.131:2375dockerHost>

        <cmd>["java", "-version"]cmd>
        <entryPoint>["java", "-jar", "${project.build.finalName}.jar"]        entryPoint>
        
        <resources>
            <resource>
