How To Upgrade Docker to a Specific Version on Ubuntu

Ubuntu 10

In this tutorial, we will guide you through the process of upgrading Docker to a specific version on your Ubuntu system. This can be particularly useful if you require a certain version for compatibility with a specific software or for testing purposes.

Quick Answer

To upgrade Docker to a specific version on Ubuntu, you need to remove the existing Docker installation, add the Docker repository, update the package list, and install the desired version using the apt-get install command. Additionally, if you want to upgrade Docker Compose, you can remove the existing binary, download the specific version from the official GitHub releases page, and set the correct permissions.

What is Docker?

Docker is an open-source platform that automates the deployment, scaling, and management of applications. It uses containerization technology to bundle an application and its dependencies into a single object, which can be easily distributed and run on any system that has Docker installed.

Preparing for the Upgrade

Before we start, it’s important to ensure that you have administrative access to your Ubuntu system, as you’ll need to execute commands with sudo privileges.

Firstly, let’s remove the existing Docker installation. This can be done using the following command:

sudo apt-get remove docker-ce docker-ce-cli containerd.io

Here, apt-get remove is used to remove the packages. The docker-ce, docker-ce-cli, and containerd.io packages are the Docker Community Edition, Docker CLI, and containerd packages respectively.

Adding Docker Repository

Next, we need to add the Docker repository to our system. This is necessary because the default Ubuntu repositories may not contain the specific version of Docker that you need. The official Docker documentation provides detailed instructions on how to do this.

Updating the Package List

Once the Docker repository is added, you need to update the package list. This ensures that apt-get knows about the new packages available in the Docker repository. You can do this by running the following command:

sudo apt-get update

Installing a Specific Version of Docker

Now that our system is prepared, we can install the desired version of Docker. This can be done by specifying the version number in the apt-get install command as follows:

sudo apt-get install docker-ce=20.10.17 docker-ce-cli=20.10.17 containerd.io

In this command, docker-ce=20.10.17 and docker-ce-cli=20.10.17 specify the versions of Docker CE and Docker CLI that we want to install, respectively.

After running this command, Docker version 20.10.17 should be installed on your Ubuntu system.

Upgrading Docker Compose

If you also want to upgrade Docker Compose to a specific version, you can follow these steps:

  1. Remove the existing Docker Compose binary:
sudo rm /usr/local/bin/docker-compose
  1. Visit the official Docker Compose GitHub releases page and determine the desired version number.
  2. Download the specific version of Docker Compose using the following command (replace <VERSION> with the desired version number):
sudo curl -L "https://github.com/docker/compose/releases/download/<VERSION>/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

In this command, curl -L is used to follow redirects and download the file. The URL is the direct link to the Docker Compose binary for the specified version.

  1. Set the correct permissions for the Docker Compose binary:
sudo chmod +x /usr/local/bin/docker-compose

This command changes the permissions of the downloaded binary, making it executable.

After following these steps, you should have the desired version of Docker Compose installed on your system.
