本地打包

我们使用jar包与配置文件分离的方式进行打包：

配置文件放在config目录下，项目依赖的jar包放在lib目录下。

docker远程访问

修改 /usr/lib/systemd/system/docker.service 文件，ExecStart中加入如下内容

-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

重启docker让它生效

systemctl daemon-reload    
systemctl restart docker

idea测试docker连接

可以看到连接成功：

制作镜像

项目中引入docker-maven-plugin插件，在pom.xml引入插件并做相应的配置：

1、打包的时候忽略resource配置

FROM openjdk:8
ARG SERVICE_PACKAGE
MAINTAINER zhuhongliang 'castile.github.io'
ENV APP_HOME=/opt/castile/app

ADD opt/castile/app /opt/castile/app/
EXPOSE 9090
WORKDIR /opt/castile/app
#CMD  /bin/bash ${APP_HOME}/config/docker-start.sh
ENTRYPOINT ["java", "-Xbootclasspath/a:/opt/castile/app/config", "-Djava.ext.dirs=/opt/castile/app/lib:$JAVA_HOME/jre/lib/ext","-jar","/opt/castile/app/castile-seckill-0.0.1-SNAPSHOT-boot.jar"]

推送至docker私服：

启动部署

1
2
docker run -d --name castile -p 9090:9090 -v /opt/applications/castile-seckill/config/:/opt/castile/app/config  192.168.160.140:5000/castile-seckill:0.0.1-SNAPSHOT

这里设置宿主机的opt/applications/castile-seckill/config/目录和容器内/opt/castile/app/config目录映射，为了修改配置方便些。

执行的java命令：

1
java -Xbootclasspath/a:/opt/castile/app/config -Djava.ext.dirs=/opt/castile/app/lib:$JAVA_HOME/jre/lib/ext -jar /opt/castile/app/castile-seckill-0.0.1-SNAPSHOT-boot.jar

部署msql

因为项目依赖mysql，因此需要把mysql容器先启动，再启动项目

1
docker run --name mysql8 -v /var/mysql/data:/var/lib/mysql -v /var/mysql/conf.d -e MYSQL_ROOT_PASSWORD=123456 -p 3306:                                      3306 -d mysql:8.0.32

设置远程访问：

1
select host, user, plugin,  authentication_string, password_expired from user;
1
2
3
4
5
ALTER USER root@'%' IDENTIFIED WITH mysql_native_password BY '123456';
ALTER USER root@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

刷新权限
 FLUSH PRIVILEGES;

测试访问

浏览器输入：

1
http://192.168.160.140:9090/login.html

已经可以成功访问啦，可以验证基本功能都正常。
