#使用docker构建工程步骤
|
||
### 1. 使用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>192.168.0.188</id>
|
||
<username>admin</username>
|
||
<password>admin12345</password>
|
||
<configuration>
|
||
<email>smallchill@163.com</email>
|
||
</configuration>
|
||
</server>
|
||
</servers>
|
||
|
||
<pluginGroups>
|
||
<pluginGroup>io.fabric8</pluginGroup>
|
||
</pluginGroups>
|
||
```
|
||
|
||
### 2. docker开启远程访问
|
||
|
||
如果没有远程访问,会报 `Connect to 192.168.0.188:2375 [/192.168.0.188] 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. 配置http访问
|
||
因为docker1.3.2版本开始默认docker registry使用的是https，我们设置Harbor默认http方式，所以当执行用docker login、pull、push等命令操作非https的docker regsitry的时就会报错。
|
||
解决办法：配置`/etc/docker/daemon.json`
|
||
|
||
```
|
||
[root@localhost harbor]# vi /etc/docker/daemon.json
|
||
{
|
||
"registry-mirrors": ["https://3dse7md.mirror.aliyuncs.com"]
|
||
}
|
||
```
|
||
|
||
将其修改为：
|
||
|
||
```
|
||
{
|
||
"registry-mirrors": ["https://3dse7md.mirror.aliyuncs.com"],
|
||
"insecure-registries":["192.168.0.188"]
|
||
}
|
||
```
|
||
|
||
### 4. 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>io.fabric8</groupId>
|
||
<artifactId>docker-maven-plugin</artifactId>
|
||
<configuration>
|
||
<skip>${docker.fabric.skip}</skip>
|
||
</configuration>
|
||
</plugin>
|
||
</plugins>
|
||
</build>
|
||
```
|
||
|
||
### 5. 在每个需要构建子项目的根目录下加入Dockerfile,内容可参考如下
|
||
|
||
```
|
||
FROM energyx/alpine-java:openjdk8-openj9_cn_slim
|
||
|
||
MAINTAINER energyjava@qq.com
|
||
|
||
RUN mkdir -p /energy/gateway
|
||
|
||
WORKDIR /energy/gateway
|
||
|
||
EXPOSE 80
|
||
|
||
ADD ./target/energy-gateway.jar ./app.jar
|
||
|
||
ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "app.jar"]
|
||
|
||
CMD ["--spring.profiles.active=test"]
|
||
```
|
||
|
||
### 6. 在工程根目录的docker-compose.yml下加入配置，内容可参考如下
|
||
```
|
||
energy-gateway:
|
||
image: "${REGISTER}/energy-gateway:${TAG}"
|
||
ports:
|
||
- 80:80
|
||
networks:
|
||
energy_net:
|
||
ipv4_address: 192.168.2.1
|
||
```
|
||
|
||
### 7. 一切配置完毕，采用fabric插件命令执行构建推送：
|
||
```
|
||
mvn clean package docker:build docker:push
|
||
``` |
