Question

我正在尝试通过使用dockerfile-maven-plugin为我的spring boot maven项目构建一个docker映像。我在Windows 7上使用Docker Tool Box，并且运行良好。

我遇到了以下错误：

无法加载Google应用程序默认凭据 java.io.IOException：应用程序默认凭据不是可用。如果它们在Google Compute Engine中运行，则可用。否则，环境变量GOOGLE_APPLICATION_CREDENTIALS 必须定义为指向定义凭据的文件。看到 https://developers.google.com/accounts/docs/application-default-credentials 有关更多信息。

    </plugins>
</build>

我不明白为什么我们需要Google默认证书来构建本地映像。请帮助我，因为我是Docker World的新手。

似乎是bug，默认情况下，插件将googleContainerRegistryEnabled标志设置为true，因此您必须将该标志更改为false，请尝试以下操作：

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
    <spring-cloud.version>Greenwich.RC2</spring-cloud.version>
    <docker.image.prefix>prefix</docker.image.prefix>
    <docker.image.name>${project.artifactId}</docker.image.name>
    <docker.image.tag>${project.version}</docker.image.tag>
    <docker.file>Dockerfile</docker.file>
</properties>
        ...
        <plugin>
            <groupId>com.spotify</groupId>
            <artifactId>dockerfile-maven-plugin</artifactId>
            <version>1.4.10</version>
            <configuration>
                <googleContainerRegistryEnabled>false</googleContainerRegistryEnabled>
                <repository>${docker.image.prefix}/${docker.image.name}</repository>
                <tag>${docker.image.tag}</tag>
                <dockerfile>${docker.file}</dockerfile>
            </configuration>
            <executions>
                <execution>
                    <id>build</id>
                    <goals>
                        <goal>build</goal>
                        <goal>tag</goal>
