Use maven plugin to build micro-mirror services Docker

1. Add a plug-in pom service

                        <plugin>
     <groupId>com.spotify</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <version>0.4.13</version>
    <configuration>
        <imageName>eureka</imageName>
        <dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory>
        <dockerHost>http://Docker宿主机ip:2375</dockerHost>
        <resources>
            <resource>
                <targetPath>/</targetPath>
                <directory>${project.build.directory}</directory>
                <include>${project.build.finalName}.jar</include>
            </resource>
        </resources>
    </configuration>

</plugin>

2. Add the src / main / docker source folder, and add Dockerfile, content:

FROM java:8


VOLUME /temp


ADD eureka-service-1.0.jar app.jar
RUN bash -c 'touch /app.jar'


EXPOSE 8088

ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

3. used locally: mvn clean package docker: build -DskipTests

If you're lucky enough, you can build on top of three steps should be mirrored on the server locally. I said the following about a variety of pit encountered! ! !

1) Failed to execute goal com.spotify: docker-maven-plugin: 0.4.13: build (default-cli) on project springb: Exception caught: java.util.concurrent.ExecutionException: com.spotify.docker.client.shaded .javax.ws.rs.ProcessingException: org.apache.http.conn.HttpHostConnectException: Connect to localhost: 2375 [localhost / 127.0.0.1, localhost / 0: 0: 0: 0: 0: 0: 0: 1] failed : Connection refused: connect ==== "this problem can be configured in the pom <dockerHost> http: // Docker host ip: 2375 </ dockerHost> to solve, but doing so may quote the following fault, I That's it

2） Failed to execute goal com.spotify:docker-maven-plugin:0.4.13:build (default-cli) on project eureka-service: Exception caught: Timeout: GET http://10.61.213.105:2372135/version: com.spotify.docker.client.shaded.javax.ws.rs.ProcessingException: org.apache.http.conn.ConnectTimeoutException: Connect to 10.61.213.105:2375 [/10.61.213.105] failed: connect timed out

Here is the solution ==================== ========================== ===========

/usr/lib/systemd/system/docker.service add attributes:

The ExecStart = / usr / bin / dockerd -current into ExecStart = / usr / bin / dockerd -H tcp: //0.0.0.0: 2375 -H unix: //var/run/docker.sock, the original \ to retention and systemctl daemon-reload. Restart docker, telnet success (believe me there are a lot of pit), the effect is as follows:! [Here insert a picture description] (https://img-blog.csdnimg.cn/20200219224008611.png?x-oss-process=image / watermark, type_ZmFuZ3poZW5naGVpdGk, shadow_10, text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zMjgyMjc1OQ ==, size_16, color_FFFFFF, t_70)

3) If the above problem persists, there is no need to check the server port to open remote connections, the firewall may need to do some operations that can find some information on the Internet, and finally Good luck, do not use this kind can jenkins way up. . .
