## 一：环境准备
|
||||
|
||||
1.docker环境
|
||||
|
||||
2.docker-compose环境
|
||||
|
||||
3.jar包
|
||||
|
||||
注意：
|
||||
|
||||
该案例主要是网络的配置（network）创建网络；使用网络
|
||||
|
||||
该案例主要是links使用（相当于本地服务器域名解析）
|
||||
|
||||
项目在连接数据库时，可以在docker-compose使用links连接hostname（项目中数据库地址改为hostname的值）
|
||||
|
||||
该项目配置了数据库在docker-compose文件中直接导入（官方Dockerfile中有专门的目录和执行脚本）
|
||||
|
||||
## 二：Docker-compose
|
||||
|
||||
#### 1.准备
|
||||
|
||||
|
||||
|
||||
#### 2.Dockerfile文件
|
||||
|
||||
```shell
|
||||
[root@nfs-harbor a]# cat Dockerfile
|
||||
FROM centos:7
|
||||
MAINTAINER "xingdian" <xingdian@gmail.com>

||||
ENV LANG=en_US.UTF-8
|
||||

|
||||

|
||||
ADD jdk-8u211-linux-x64.tar.gz /usr/local/
|
||||
RUN mv /usr/local/jdk1.8.0_211 /usr/local/java
|
||||
ENV JAVA_HOME /usr/local/java/
|
||||
ENV PATH $PATH:$JAVA_HOME/bin
|
||||
COPY mayday.jar /usr/local
|
||||
EXPOSE 10086
|
||||
CMD java -jar /usr/local/mayday.jar
|
||||
```
|
||||
|
||||
#### 3.Docker-compose文件
|
||||
|
||||
