Hyperledger Fabric framework runs on Docker Engine. So it is important to verify that Docker Engine is running correctly on your local Ubuntu system. Here are some suggestions on how to verify the Docker Engine.

1. Verify version of the Docker Engine and make sure it is running as a background process (daemon):

$ docker --version

Docker version 18.09.2, build 6247962

$ ps -e | grep dockerd
17939 ?        00:39:58 dockerd

2. Check the status of the Docker Engine background process:

$ sudo systemctl status docker

● docker.service - Docker Application Container Engine
   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: e
   Active: active (running) since Thu 2019-03-31 16:58:03 UTC; 3 days
