#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>
|
2019-04-01 22:56:46 +08:00
|
|
|
|
<id>10.211.55.5</id>
|
2019-01-30 17:06:23 +08:00
|
|
|
|
<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
|
|
|
|
|
|
|
2019-04-01 22:56:46 +08:00
|
|
|
|
如果没有远程访问,会报 `Connect to 10.211.55.5:2375 [/10.211.55.5] failed: Connection refused: connect`
|
2019-01-30 17:06:23 +08:00
|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
|
```
|
