spotify/dockerfile-maven 插件：无法构建图像：javax.net.ssl.SSLException：无法识别的 SSL 消息，纯文本连接

Question

maven-plugin 来构建我的 docker 镜像。

每当我跑步时

dockerfile:build

我总是收到此错误：

"failed to execute goal com.spotify:dockerfile-maven-plugin:1.3.6:build (default-cli) on project XXX: Could not build image"
"Caused by: com.spotify.docker.client.shaded.javax.ws.rs.ProcessingException: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?"

我会在最后附上错误日志。

请您看看这里出了什么问题吗？

这是我用于此插件的 pom.xml 文件。

<plugin>
        <groupId>com.spotify</groupId>
        <artifactId>dockerfile-maven-plugin</artifactId>
        <version>1.3.6</version>
        <executions>
            <execution>
                <id>default</id>
                <goals>
                    <goal>build</goal>
                    <goal>push</goal>
                </goals>
            </execution>
        </executions>
        <configuration>
            <repository>company/imagename</repository>
            <tag>${project.version}</tag>
        </configuration>
</plugin>

docker版本是：17.06.2-ce

操作系统：Windows 10。

我检查了“general--Expose daemon on tcp://localhost:2375”，并在 Windows 的 docker 中添加了不安全的注册表。

我还在系统变量中添加了 DOCKER_HOST="tcp://localhost:2375" 和 DOCKER_CERT_PATH 。

Answer 1

您需要将 pullNewerImage 设置为 false，因为它默认为 true。 欲了解更多详情，请参阅以下链接。 https://github.com/spotify/dockerfile-maven/issues/3

Answer 2

如果您使用的是 Windows 10 和 docker 版本：版本 2.0.0.3 (31259) 或更高版本，您需要启用不带 TLS 选项的 Expose Daemon！

第1步：右键单击“Docker Desktop正在运行图标”

第2步：点击设置

第 3 步：在“常规选项卡”中，您必须启用复选框“在 tcp://localhost:2375 上公开守护进程而不使用 TLS”

如果您不启用此功能，您将在后续步骤中看到此错误 - java.net.ConnectException：连接被拒绝：连接

Answer 3

我遇到了同样的问题，我不知道如何解决，为什么这个插件不支持config docker post？
