Question

我使用brew install docker安装了Docker可执行文件，并且可以在PATH的{{1}}中看到它：

bash

我为此$ which docker /usr/local/bin/docker设置了一个Spring Boot应用程序：

Dockerfile

当我运行Docker GUI应用程序时，Maven会构建该应用程序，我可以运行它并在本地查看它。但是，当Docker GUI应用程序未运行时，即使它在bash可执行文件中，Maven也无法构建该应用程序，因为它无法建立与Docker的连接：

FROM openjdk:8-jre
MAINTAINER ...

COPY dist /dist/
ARG JAR_FILE
COPY target/${JAR_FILE} /target/app.jar
EXPOSE 8080
CMD ["java", "-jar", "/target/app.jar"]

Maven使用的$ mvn clean install [INFO] Scanning for projects... ... [WARNING] An attempt failed, will retry 1 more times org.apache.maven.plugin.MojoExecutionException: Could not build image ...

Answer 1

Docker使用客户端-服务器架构，“鲸鱼”应用程序提供其中一半的“服务器”。在Mac上，您需要运行桌面应用程序（或重量较大的VM，例如Docker Machine或minikube提供的VM），以使用任何Docker命令或与Docker进行交互。

Maven构建适用于运行的Docker GUI，但不适用于二进制文件
