In a nutshell: Metricbeat needs access to the Docker socket to retrieve stats from it, but the docker image we ship runs as a user by default (to make it more secure). There are several ways to allow Metricbeat accessing the docker socket:

- Running as root user inside the container
- Using file system ACLs
- Adding metricbeat user to docker group, check [Trouble running metricbeat:5.3.0 with docker module](https://discuss.elastic.co/t/trouble-running-metricbeat-5-3-0-with-docker-module/82204/7)
