Professional use of Docker Desktop in large organizations (more than 250 employees or more than $10 million in revenue) requires users to have a paid Docker subscription. While the effective date of these terms is August 31, 2021, there is a grace period until January 31, 2022, for those that require a paid subscription. For more information, see the blog Docker is Updating and Extending Our Product Subscriptions.

The list returned depends on which repositories are enabled, and is specific to your version of CentOS (indicated by the.el7 suffix in this example). Install a specific version by its fully qualified package name, which is the package name (docker-ce) plus the version string (2nd column) starting at the first colon (:), up to the first hyphen, separated by a hyphen (-). Notice that docker-ce is not installed, but the candidate for installation is from the Docker repository for Ubuntu 18.04 ( bionic ). Finally, install Docker: sudo apt install docker-ce. Docker should now be installed, the daemon started, and the process enabled to start on boot.

There are two versions of Docker – Docker CE (Community Edition) and Docker EE (Enterprise Edition). If you have a small-scale project, or you’re just learning, you will want to use Docker CE. In this tutorial, learn how to install Docker on Ubuntu 18.04. In this tutorial, we are going to learn how to install Docker CE on Ubuntu 20.04. Docker is a platform that enables developers and system administrators to build, run, and share applications with containers.

Docker is an open platform for developing, shipping, and running applications.Docker enables you to separate your applications from your infrastructure so youcan deliver software quickly. With Docker, you can manage your infrastructure inthe same ways you manage your applications. By taking advantage of Docker’smethodologies for shipping, testing, and deploying code quickly, you cansignificantly reduce the delay between writing code and running it in production.

You can download and install Docker on multiple platforms. Refer to the followingsection and choose the best installation path for you.

Docker Desktop for Mac

A native application using the macOS sandbox security model which delivers all Docker tools to your Mac.

Docker Desktop for Windows

A native Windows application which delivers all Docker tools to your Windows computer.

Docker for Linux

Install Docker on a computer which already has a Linux distribution installed.

To start the installation of Docker, we are going to use an Ubuntu instance. You can use Oracle Virtual Box to setup a virtual Linux instance, in case you don’t have it already.

The following screenshot shows a simple Ubuntu server which has been installed on Oracle Virtual Box. There is an OS user named demo which has been defined on the system having entire root access to the sever.

To install Docker, we need to follow the steps given below.

Step 1 − Before installing Docker, you first have to ensure that you have the right Linux kernel version running. Docker is only designed to run on Linux kernel version 3.8 and higher. We can do this by running the following command.

System

uname

This method returns the system information about the Linux system.

Syntax

Options

a − This is used to ensure that the system information is returned.

Return Value

This method returns the following information on the Linux system −

  • kernel name
  • node name
  • kernel release
  • kernel version
  • machine
  • processor
  • hardware platform
  • operating system

Example

Output

When we run above command, we will get the following result −

From the output, we can see that the Linux kernel version is 4.2.0-27 which is higher than version 3.8, so we are good to go.

Step 2 − You need to update the OS with the latest packages, which can be done via the following command −

This method installs packages from the Internet on to the Linux system.

Syntax

sudo apt-get update

Options

  • sudo − The sudo command is used to ensure that the command runs with root access.

  • update − The update option is used ensure that all packages are updated on the Linux system.

Return Value

None

Example

Output

When we run the above command, we will get the following result −

This command will connect to the internet and download the latest system packages for Ubuntu.

Step 3 − The next step is to install the necessary certificates that will be required to work with the Docker site later on to download the necessary Docker packages. It can be done with the following command.

Step 4 − The next step is to add the new GPG key. This key is required to ensure that all data is encrypted when downloading the necessary packages for Docker.

The following command will download the key with the ID 58118E89F3A912897C070ADBF76221572C52609D from the keyserver hkp://ha.pool.sks-keyservers.net:80 and adds it to the adv keychain. Please note that this particular key is required to download the necessary Docker packages.

Step 5 − Next, depending on the version of Ubuntu you have, you will need to add the relevant site to the docker.list for the apt package manager, so that it will be able to detect the Docker packages from the Docker site and download them accordingly.

  • Precise 12.04 (LTS) ─ deb https://apt.dockerproject.org/repoubuntu-precise main

  • Trusty 14.04 (LTS) ─ deb https://apt.dockerproject.org/repo/ ubuntu-trusty main

  • Wily 15.10 ─ deb https://apt.dockerproject.org/repo ubuntu-wily main

  • Xenial 16.04 (LTS) - https://apt.dockerproject.org/repo ubuntu-xenial main

Since our OS is Ubuntu 14.04, we will use the Repository name as “deb https://apt.dockerproject.org/repoubuntu-trusty main”.

And then, we will need to add this repository to the docker.list as mentioned above.

Step 6 − Next, we issue the apt-get update command to update the packages on the Ubuntu system.

Step 7 − If you want to verify that the package manager is pointing to the right repository, you can do it by issuing the apt-cache command.

In the output, you will get the link to https://apt.dockerproject.org/repo/

Step 8 − Issue the apt-get update command to ensure all the packages on the local system are up to date.

Step 9 − For Ubuntu Trusty, Wily, and Xenial, we have to install the linux-image-extra-* kernel packages, which allows one to use the aufs storage driver. This driver is used by the newer versions of Docker.

It can be done by using the following command.

Step 10 − The final step is to install Docker and we can do this with the following command −

Here, apt-get uses the install option to download the Docker-engine image from the Docker website and get Docker installed.

The Docker-engine is the official package from the Docker Corporation for Ubuntu-based systems.

In the next section, we will see how to check for the version of Docker that was installed.

Docker Version

To see the version of Docker running, you can issue the following command −

Syntax

Options

Docker Ce Download Linux
  • version − It is used to ensure the Docker command returns the Docker version installed.

Return Value

The output will provide the various details of the Docker version installed on the system.

Example

Output

Docker Ce Download Linux

When we run the above program, we will get the following result −

Docker Info

To see more information on the Docker running on the system, you can issue the following command −

Syntax

Options

  • info − It is used to ensure that the Docker command returns the detailed information on the Docker service installed.

Return Value

The output will provide the various details of the Docker installed on the system such as −

  • Number of containers
  • Number of images
  • The storage driver used by Docker
  • The root directory used by Docker
  • The execution driver used by Docker

Example

Output

When we run the above command, we will get the following result −
