how to install eclipse Ditto

Question

I am trying to install Eclipse Ditto on my Ubuntu 18 machine, Maven and OpenJDK version "1.8.0_222", Docker version 18.09.7 are installed. When running the command:

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

I get the following error:

What am I missing here?

Thanks in advance!

Hi Samia, do you really wish to build the docker images yourself? Or are you trying to start the ditto docker images? — Yannic Bürgmann, Nov 21 '19 at 12:12

In order to "install" Ditto, you don't have to build it yourself (so you don't need to do mvn clean install). Please have a look at the Running Ditto guide. The simplest way is to just start it with Docker compose liked documented there.

You can find other options for deployment here (e.g. Kubernetes, OpenShift, deployment via Helm).
