我正在尝试在Ubuntu 18计算机上安装Eclipse Ditto，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？
提前致谢!
最佳答案
为了“安装” Ditto，您不必自己构建它(因此您不需要执行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)。
