Both accounts are locked (no default password is available). The images for the LXD containers have both a root account and also a user account, in the Ubuntu images is called ubuntu. We instructed to execute ( exec) in the neo4j container the command that appears after the - separator.

It’s good to go! Connecting to the LXD container
Here, the container is in the RUNNING state, and also has a private IP address. It takes a few seconds for a new container to launch. | NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS | Let’s see the container details: $ lxc list Here we launched a container named neo4j, that runs Ubuntu 16.04 (Xenial, hence ubuntu:x). Then, let’s start with creating a container for neo4j: $ lxc launch ubuntu:x neo4j
