将.war部署到fabric8io docker-maven-plugin的码头映像中

Question

我对Docker和fabric8io docker-maven-plugin非常陌生。要将.war部署到jboss/wildfly one导出的映像中，我遇到了一些困难。我可以通过命令行成功地构建.war附带的映像，但是我不能通过前面提到的插件来实现。据我所知，一旦您给出了正确的上下文和Dockerfile，就应该只需：

<build>
  <finalName>${project.build.finalName}.${project.packaging}</finalName>
  ...
  <assembly>
    <descriptorRef>artifact</descriptorRef>
  </assembly>
</build>

但是我发现了这个错误：

[INFO] <<< docker-maven-plugin:0.19.0:build (default-cli) < package @ YoOffer <<<
[INFO] 
[INFO] --- docker-maven-plugin:0.19.0:build (default-cli) @ YoOffer ---

[WARNING] The following patterns were never triggered in this artifact inclusion filter:

这里是我的沙箱。

更新：，我清理了我的pom中的一些混乱。现在看起来是这样的：

<images>
    <image>
        <alias>yowildfly</alias>
        <name>jboss/wildfly</name>
        <build>
        <!--
            <assembly>
                <descriptorRef>${project.basedir}/src/test/resources/DOCKER/assembly.xml</descriptorRef>
            </assembly>
        -->
            <args>
                <webapp>target/${project.build.finalName}.${project.packaging}</webapp>
            </args>
            <dockerFileDir>${project.basedir}</dockerFileDir>
            <dockerFile>src/test/resources/DOCKER/wildfly/Dockerfile</dockerFile>
            </build>
            <run>
                <ports>
                    <port>8080:8080</port>
                </ports>
            </run>
        </image>
...
</images>

现在我得到了这个错误：

...    
[ERROR] DOCKER> Unable to build image [jboss/wildfly]

因此，对于docs，与dockerFile一起使用的dockerFile应该标记映像构建上下文。

Answer 1

我误解了fabric8io的插件文档。您可以同时使用dockerFileDir和dockerFile，但是构建上下文不会被设置为dockerFileDir值。要从target部署我的工件，我必须将Dockerfile放到我的项目的根目录，用项目根路径设置dockerFileDir值，从Dockerfile中删除dockerFile条目。我的沙盒是这样更新的。下一步是通过在assembly中使用build conf，以一种更干净的方式实现同样的目标。

Answer 2

您应该能够将您的Dockerfile放在您想要的任何位置，而不受Docker工作方式的限制。因此，在io.fabric8 maven插件中有一个选项，它允许您复制您在构建码头映像时所需的文件。对我来说是这样的：

1. 我决定把我的Dockerfile放进src/main/docker
2. 我需要两个文件在码头映像构建：
   • target/SomeName.war (这是包maven阶段的产物)
   • src/main/resources/OtherFiles.xml (这只是我还需要的另一种资源)

​

io.fabric8插件配置在pom.xml文件中：

<plugin>
  <groupId>io.fabric8</groupId>
  <artifactId>docker-maven-plugin</artifactId>
  <version>0.24.0</version>
  <configuration>

          <dockerFile>Dockerfile</dockerFile>

                  <outputDirectory>./</outputDirectory>
                  <destName>SomeName.war</destName>

                <file>
                  <source>${project.basedir}/src/test/resources/OtherFiles.xml</source>
                  <outputDirectory>./</outputDirectory>
                  <destName>OtherFiles.xml</destName>
                </file>
              </files>
            </inline>
          </assembly>
        </build>
        <run>
          <ports>
            <port>8080:8080</port>
          </ports>
          <network>
            <mode>host</mode>
          </network>
          <wait>
            <log>.*WildFly .* \(WildFly .*\) started in [0-9]*ms - Started [0-9]* of [0-9]* services</log>
            <time>360000</time>
          </wait>
        </run>
      </image>
    </images>
    <showLogs>true</showLogs>
  </configuration>
  <!-- Connect start/stop to pre- and post-integration-test phase, respectively if you want to start your docker containers during integration tests -->
  <executions>
    <execution>
      <id>start</id>
      <phase>pre-integration-test</phase>
      <goals>
        <!-- "build" should be used to create the images with the artifact -->
        <goal>build</goal>
        <goal>start</goal>
      </goals>
    </execution>
    <execution>
      <id>stop</id>
      <phase>post-integration-test</phase>
      <goals>
        <goal>stop</goal>
      </goals>
    </execution>
  </executions>
</plugin>

最后，我如何在Dockerfile中引用这些文件

ADD maven/SomeName.war /opt/jboss/wildfly/standalone/deployments/

请注意，maven是您在pom.xml (<name>maven/</name>)中输入的名称。你当然可以用你想要的任何东西来代替。
