About this Hands-on Lab

Docker CE is a great way to get started using the Docker engine. It is free and open-source, but provides a high-quality container runtime. This lab will help you practice the steps involved in installing and configuring the Docker Engine. You will practice installing Docker CE and configuring a logging driver. This lab will help provide you with some basic insight into how the Docker Engine is installed and configured on systems in the real world.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Install Docker CE on the server.
  1. First, set up the Docker Repository.

    sudo apt-get update
    sudo apt-get -y install 
    curl -fsSL | sudo apt-key add -
    sudo add-apt-repository 
     "deb [arch=amd64] 
     $(lsb_release -cs) 
  2. Install docker packages.

    sudo apt-get update
    sudo apt-get install -y docker-ce=5:18.09.5~3-0~ubuntu-bionic docker-ce-cli=5:18.09.5~3-0~ubuntu-bionic
  3. Verify that your installation is working.

    sudo docker version
Give cloud_user access to run Docker commands.
  1. Add cloud_user to the docker group.

    sudo usermod -a -G docker cloud_user

    Log out of the server, then log back in.

  2. Once you are logged back on, you can verify cloud-user‘s access:

    docker version
Set the default logging driver to syslog.
  1. Edit daemon.json:

    sudo vi /etc/docker/daemon.json
  2. Add configuration to daemon.json to set the default logging driver.

     "log-driver": "syslog"
  3. Restart docker.

    sudo systemctl restart docker
  4. Verify that the logging driver was set properly like so:

    docker info | grep Logging
  5. This command should return a line that says:

    Logging Driver: syslog

Additional Resources

Your company is ready to start using Docker on some of their servers. In order to get started, they want you to set up and configure Docker CE on a server that has already been set up. You will need to make sure that the server meets the following specifications:

  • Docker CE is installed and running on the server.
  • Use Docker CE version 5:18.09.5~3-0~ubuntu-bionic.
  • The user cloud_user has permission to run docker commands.
  • The default logging driver is set to syslog.

If you get stuck, feel free to check out the solution video, or the detailed instructions under each objective. Good luck!
