#使用docker构建工程步骤
###1. 使用docker-harbor作为私有库,需要配置maven,找到setting.xml( `linux可以使用find / -name settings.xml`)加入以下配置
```
<servers>
<server>
<id>192.168.186.129</id>
<username>admin</username>
<password>Harbor12345</password>
<configuration>
<email>smallchill@163.com</email>
</configuration>
</server>
</servers>
<pluginGroups>
<pluginGroup>com.spotify</pluginGroup>
</pluginGroups>
```
###2. docker开启远程访问
如果没有远程访问,会报 `Connect to 192.168.186.129:2375 [/192.168.186.129] failed: Connection refused: connect`
在`/usr/lib/systemd/system/docker.service`,配置远程访问。主要是在[Service]这个部分,加上下面两个参数:
```
cd /usr/lib/systemd/system
vi docker.service
ExecStart=
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
```
###3. 在每个需要构建子项目的pom.xml下加入配置,内容可参考如下
```
<build>
<plugins>
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>${docker.plugin.version}</version>
<configuration>
<imageName>${docker.registry.url}/blade/${project.artifactId}:${project.version}</imageName>
<dockerDirectory>${project.basedir}</dockerDirectory>
<dockerHost>${docker.registry.host}</dockerHost>
<resources>
<resource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.build.finalName}.jar</include>
</resource>
</resources>
<registryUrl>${docker.registry.url}</registryUrl>
<serverId>${docker.registry.url}</serverId>
<pushImage>true</pushImage>
</configuration>
</plugin>
</plugins>
</build>
```
###4. 在每个需要构建子项目的根目录下加入Dockerfile,内容可参考如下
```
FROM anapsix/alpine-java:8_server-jre_unlimited
MAINTAINER smallchill@163.com
RUN mkdir -p /blade/gateway
WORKDIR /blade/gateway
EXPOSE 80
ADD ./target/blade-gateway.jar ./app.jar
CMD java -Djava.security.egd=file:/dev/./urandom -jar app.jar --spring.profiles.active=test
```
###5. 在工程根目录的docker-compose.yml下加入配置内容可参考如下
```
blade-gateway:
image: "${REGISTER}/blade/blade-gateway:${TAG}"
ports:
- 80:80
networks:
blade_net:
ipv4_address: 192.168.2.1
```
