The default user is ubuntu with password ubuntu Use the sudo command to run tasks as root in the container.Please make a note of login details, you would require this information to log in to the containers.If you want to create a container based on Ubuntu 1.Starting Linux Containers Once after creating the containers, start it using the following command, d to run containers in the background.Now, take a console of the container using the following command.Enter the username ubuntu and password ubuntu to log in.You can find the default credential at the end of the output during the creation of a container.Sample output Connected to tty 1.Type lt Ctrla q to exit the console, lt Ctrla Ctrla to enter Ctrla itself.Ubuntu Xenial Xerus development branch ubuntulxc pts0.Password. Welcome to Ubuntu Xenial Xerus development branch GNULinux 4.Documentation https help.The programs included with the Ubuntu system are free software.Ubuntu comes with ABSOLUTELY NO WARRANTY, to the extent permitted by.To run a command as administrator user root, use sudo lt command.See man sudoroot for details.You can perform all your work in this container as like you do on a Linux servers.To exit from the containers console, press Ctrla followed by q.Now, you will be returned to host computers terminal.If you want to connect to the console of the container again the container is still running, run the following command.Working with Linux Containers To listing down the available containers on the host machine, use the following command.Use the following command to list down the containers that are currently running on the host computer.You could see the same output for both of the commands as I have only one container which is currently running.You can use the following command to list the containers with detailed information.NAME STATE AUTOSTART GROUPS IPV4 IPV6.RUNNING 0 1.To get the details of the running container, issue the following command.Name ubuntulxc.State RUNNING.PID 2.IP 1.CPU use 0.Blk.

BYou can use IP address to connect to the containers.You can stop running containers using lxc stop command, use the following command to stop ubuntulxc.Cloning containers LXC offers a feature of cloning a container from the existing container, run the following command to clone an existing ubuntulxc container to a new container ubuntulxcclone.Note You must stop a container before initiating the clone.N ubuntulxcclone.Check out whether a container is created successfully.
