Question

我试图在我的Ubuntu 18计算机上安装Eclipse Ditto，并安装了Maven和OpenJDK版本“ 1.8.0_222”，以及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：

我在这里想念什么？

谢谢！

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。最简单的方法是从此处记录的Docker compose开始。

您可以找到其他用于部署here的选项（例如Kubernetes，OpenShift，通过Helm进行部署）。
