【问题描述】：

我正在尝试在我的 Ubuntu 18 机器上安装 Eclipse Ditto，安装了 Maven 和 OpenJDK 版本“1.8.0_222”，Docker 版本 18.09.7。运行命令时：

mvn clean install -Pdocker-build-image \
    -Ddocker.daemon.url=unix:///var/run/docker.sock

我收到以下错误：

我在这里错过了什么？

提前致谢！

【问题讨论】：

嗨 Samia，您真的希望自己构建 docker 映像吗？或者您是否正在尝试启动同上的 docker 图像？

标签： maven docker eclipse-ditto

【解决方案1】：

为了“安装” Ditto，您不必自己构建它（因此您无需执行mvn clean install）。请查看Running Ditto 指南。最简单的方法是从那里记录的 Docker compose 开始。

您可以找到其他部署选项here（例如 Kubernetes、OpenShift、通过 Helm 部署）。
