Question

这是我的错误信息：

似乎暴露要求一个参数。应该是什么？

这是dockerfile。

我尝试将EXPOSE_PORT设置为22和8899无效。此错误信息：

[ERROR] Failed to execute goal com.spotify:docker-maven-plugin:0.4.13:build (default) on project spri

谢谢！

这是除pom.xml之外有关管理服务器的插件：

<profiles>
    <profile>
        <id>buildDocker</id>
        <build>
            <plugins>
                <plugin>
                    <groupId>com.spotify</groupId>
                    <artifactId>docker-maven-plugin</artifactId>
                    <version>${docker.plugin.version}</version>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

Answer 1

您还可以使用Jib进行设置

<configuration>
    <container>
        <ports>
            <port>xxxx</port>
        </ports>
    </container>
</configuration>

Answer 2

EXPOSE指令通知Docker容器在运行时侦听指定的网络端口。您可以指定端口是侦听TCP还是UDP，如果未指定协议，则默认为TCP。

EXPOSE <port> [<port>/<protocol>...]

示例： EXPOSE 80/udp

Refer this.

也see this.

mvn全新安装-PbuildDocker不起作用

谢谢！
