我正在使用 DockerToolBox。我正在尝试将 Spring-Boot 与 Docker 一起使用。我正在关注本教程。我的项目的 pom.xml 是这样的：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    </parent>

    <properties>
        <java.version>1.8</java.version>
        <docker.image.prefix>jayram</docker.image.prefix>
    </properties>

        </dependency>
    </dependencies>


    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>0.4.13</version>
                <configuration>
                    <imageName>${docker.image.prefix}/${project.artifactId}</imageName>
                    <dockerDirectory>src/main/docker</dockerDirectory>
                    <!--dockerHost>https://192.168.99.100:2376</dockerHost-->
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

当我运行此命令时：mvn package docker:build，我收到以下错误：

Failed to execute goal com.spotify:docker-maven-plugin:0.4.13:build (default-cli) on project jk-spring-boot-docker: 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 -> [Help 1]

我尝试添加<dockerHost>https://192.168.99.100:2376</dockerHost>pom.xml，但出现以下错误：

Failed to execute goal com.spotify:docker-maven-plugin:0.4.13:build (default-cli) on project jk-spring-boot-docker: Exception caught: Timeout: GET https://192.168.99.100:2376/version: com.spotify.docker.client.shaded.javax.ws.rs.ProcessingException: org.apache.http.conn.ConnectTimeoutException: Connect to 192.168.99.100:2376 [/192.168.99.100] failed: connect timed out

更新：

Docker 没有运行。我启动了 docker，然后运行命令，它给出了以下错误：

Failed to execute goal com.spotify:docker-maven-plugin:0.4.13:build (default-cli) on project jk-spring-boot-docker: Exception caught: java.util.concurrent.ExecutionException: com.spotify.docker.client.shaded.javax.ws.rs.ProcessingException: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

请帮我解决这个问题。
