Download Docker Container Manually


To enable Kubernetes support and install a standalone instance of Kubernetes running as a Docker container, select Enable. To manually add a custom. This is a much better solution as the manual download has much lower chances to fail than restarting the docker-machine hoping that docker pull starts working. To download a docker image manually, there is a script called 'download-frozen-image-v2.sh' in the Moby project that lets us do that.

Docker cp Command. The quickest way to copy files to and from a Docker container is to use the docker cp command. This command closely mimics the Unix cp command and has the following syntax: docker cp. Before we look at some examples of this command, let's assume we have the following Docker containers running: CONTAINER ID IMAGE. After starting the Docker Engine service, proceed to download the pre-created.NET sample image on the Docker Hub registry: docker pull microsoft/dotnet-samples:dotnetapp-nanoserver-1809. After the download, you can deploy a simple Docker container that runs the.Net ‘Hello World’ application.

In our last tutorial, we have discussed the fundamentals of Docker. To begin experimenting with Docker, like learning the commands, working with Docker, and deploying applications, we need first to install Docker on our machine. Almost all operating systems support Docker, but we need to follow a specific sequence of installation. In this tutorial, we will discuss the installation of Docker on Windows and Linux. In addition, Docker Engine is supported by the following platforms.

  1. Linux.
  2. Windows OS.
  3. macOS.

Windows and Mac OS offer Docker installation through 'Docker Desktop'. In addition, Docker provides '.rpm' or '.deb' packages for Linux architectures and distributions for various Linux versions.

Subsequently, we will be discussing the following topics in this article:

How to install Docker on Linux?

We should ensure that we fulfill all the prerequisites and/or system requirements before installing Docker in a Linux environment,

System Requirements/Prerequisites

We should ensure that the Linux machine has satisfied the following requirements.

Check for OS requirements.

To install Docker on Linux, the system should be 64-bit and have one of the following Linux Ubuntu versions installed.

  • Ubuntu Focal 20.04 (LTS)
  • Ubuntu Bionic 18.04 (LTS)
  • Or, Ubuntu Xenial 16.04 (LTS)

The various architectures that support Docker Engine are x86_64 (amd64), armhf, and arm64.

Uninstall older Docker versions

Next, we need to uninstall any older Docker versions on the machine. Older versions of Docker were named docker-engine, docker.io, docker. To uninstall these versions, run the following command.

This command will remove the Docker software from the machine if any or will give a message that none were found.

Configure Driver support

Docker Engine supports overlay2, btrfs, and aufs storage drivers on Ubuntu. By default, Docker Engine uses the overlay2 driver. So we need to ensure the appropriate drivers are configured. (Usually present on the machine. If we need another like aufs, then we need to manually configure it).

How to Install Docker on Ubuntu?

We can install Docker on Ubuntu in three ways:

  1. Repositories: This is the recommended approach. In this approach, we set up Docker's repositories and install Docker in Ubuntu from these repositories. This approach makes installation as well as upgrade tasks easier.
  2. Manual Installation: In this approach, users download the 'DEB' package and install the docker manually in Ubuntu. This approach can be adopted when there is no access to the internet.
  3. Using automated convenience scripts This approach is mostly used in development and testing environments wherein users use automated convenience scripts to install Docker.

In this article, we will provide a detailed approach to install Docker in Ubuntu by using repositories.

Installing Docker using repositories

We have to set the repository before installing Docker Engine for the first time on a fresh Linux machine. Then we can install Docker Engine and upgrade it.

Download Docker Container Manually Using

The following are steps or sequences of commands to install Docker on an Ubuntu 18.04 (LTS) machine. One can repeat these same steps on machines with other versions of Ubuntu.

Set up the repository for Docker

The following sequence of steps is carried out for setting up the repository.

i. Update the 'apt' package index. For this given the following command.

The above command generates the following output.

Once the 'apt' package index is updated, install the packages that allow apt to use a repository over HTTPS. For this, execute the following command:

The above command will set up the repository. For example, this command gives the following output.

The above screenshot shows the entire process of setting up a repository due to the 'sudo apt-get install...' command.

ii. Once the repository is installed, we have to add and verify Docker's official GPG key.

Note: GPG Key: This is not Docker-specific but Linux - specific. Using the GPG key, Linux package managers can validate the integrity of the software package being installed by verifying it PGP or GPG key. Most modern Linux distributions come with a set of PGP keys installed for default repositories for that particular distribution. Docker runs its own package repositories for major distribution.

After this, add Docker's official GPG key with the following command.

Once the GPG key is added, we can verify it by giving the following command.

Executing the above commands one after the other generates the following output.

In the above screenshot, we can see the GPG key details.

iii. Once our GPG key is added, we can set up a stable repository of the 'nightly' or 'test' repository by giving the following command.

This command gives the following output.

As seen from the above output, we have used a test repository here.

Now, we have successfully set up the repository, and we can proceed with the next step of installation of Docker Engine.

Install Docker Engine

First, to install Docker Engine, we update the 'apt' package and then install the latest version of Docker Engine and 'containerd'.

To update the 'apt' package, we give the same command we have given in step 1.


Once the apt package is updated, we install the latest version of the Docker Engine.

The command is as follows:

The above command generates the following output.

We can verify if the Docker Engine is successfully installed by issuing the following command that generates the following output (partial output).

Or we can give any command like

The above command will download a test image and run it in a container. Finally, the container will run and print the informational message and exit.

Upgrade Docker Engine

If we need to upgrade the Docker Engine to another version, we once again need to execute the command.

Repeat the above installation instructions further to install the new version.

How to uninstall Docker?

To uninstall the Docker from the Linux machine (with Ubuntu), give the following command.

This will uninstall the Docker, CLI, and containerd packages from the machine.

Note that the above command will not remove images, containers, customized configurations, or volumes from the machine. So we need to delete them with the following command explicitly.

Still, if there are any additional configurations, we have to delete them manually.

What are the other Docker installation methods?

Apart from the installation method described above, we can use other installation methods as well.

Below we briefly discuss the other two methods:

Install Docker from a package

Although installing Docker using a repository is a recommended method, we can also install Docker by downloading the '.deb' package and installing it manually.

The steps involved are as follows:

Access the link https://download.docker.com/linux/ubuntu/dists/. Navigate to 'pool/stable/' . Select amd64/armf/arm64 and then download the '.deb' file. A screenshot of one of the repository contents is shown below:

We can select any folder (as per our requirements) from the 'dists' folder, and further, we can see the contents of each repository. For example, in the above screenshot, we have selected the 'eoan' folder, and then we navigate to the '.deb' file as explained in the following steps.

Install docker with the following command.

The path in the command '/path/to/package.deb' should be changed to the appropriate Docker package path.

As with the first installation method, we can verify if the Docker is installed correctly using the command.

Note: If we need a nightly or test package, we can do so by replacing the word 'stable' with 'nightly' or 'test'.

Install Docker using Convenience scripts

Installing Docker using Convenience scripts is not a recommended option, especially for the production environment. The reason Convenience scripts are not recommended :

  1. The convenience scripts mostly install packages without asking for confirmation.
  2. Also, we need 'root' or 'sudo' privileges to run the convenience scripts.
  3. Convenience scripts do not allow us to customize any installation.
  4. It, by default, installs the latest version of Docker, and we have no option to specify a version of our choice.

We can find the convenience scripts for installing edge and testing versions of Docker Engine - Community at get.docker.com and test.docker.com, respectively. We can use these scripts for installing Docker in a non-interactive mode in the development environment.

The command to run the convenience script is as follows:


  1. We should not use convenience scripts on the host machine on which the Docker is installed using other methods.

  2. We should always verify the downloaded convenience scripts before running them on the local machine.

How to install Docker on other Linux versions?

We have seen the Docker installation on the Ubuntu version of Linux. In this section, let us briefly discuss the Docker installation on other Linux versions.

One thing to keep in mind is that irrespective of the Linux distributions, we always need 64-bit installations and kernel version with 3.10 or newer. 4

Docker runs on:

  • Ubuntu
    • Xenial 16.04 LTS
    • Wily 15.10
    • Trusty 14.04 LTS
    • Precise 12.04 LTS
  • Debian
    • testing stretch
    • Debian 8.0 Jessie
    • Debian 7.0 Wheezy (with backports enabled)

The steps to install Docker on the Debian Linux version are basically the same as described above. But if we are installing docker on Debian distribution, then first, we need to enable the backports.

The steps to enable backports on Debian Wheezy are as follows:

  1. Log in to the Linux terminal with root/sudo privileges
  2. Navigate to and open '/etc/apt/sources.list.d/backports.list' . (Create the file if not already exists)
  3. Remove existing entries.
  4. Now add an entry for backports:
  1. Now update the packages using the following command:

Once the above steps are completed, proceed with the installation of Docker.

How to Install Docker on Windows?

Docker provides a community version for Microsoft windows in the form of Docker Desktop.

We can install Docker Desktop on Windows 10 Enterprise, Pro, and Education. In addition, we can install Docker on Windows 10 Home. One can download it from here. This link opens up the following screen.

When 'Get Docker' is clicked, the installer 'Docker Desktop Installer.exe' is downloaded.

Before we proceed with the installation, let us discuss the system requirements/ prerequisites of the installation.

Prerequisites for installing Docker on Windows

The Windows system on which Docker Desktop is to be installed should fulfill the following prerequisites.

  1. Windows 10 should be a 64-bit machine with one of the versions: Pro, Enterprise, or Education. The build should be 16299 or later.
  2. Windows features, namely, Hyper-V and Containers, should be enabled.
  3. For the successful running of Client Hyper-V on Windows 10, the fulfillment of the following hardware prerequisites should happen:
    • System RAM should be at least 4GB.
    • The processor (64 bit) should have Second Level Address Translation (SLAT)
    • Using BIOS settings, enable BIOS-level hardware virtualization support.

Once these requirements are fulfilled, we can proceed with the Docker Desktop installation on Windows.

How to install Docker Desktop on Windows?

One should follow the sequence of steps below to install Docker Desktop on Windows.

  1. Double Click the 'Docker Desktop Installer.exe' to begin the installation.

  2. The Docker Desktop installation begins by first downloading the files, and the installation begins as shown in the below screenshot.

The above screenshot shows the installation in progress. Once all the packed files are installed, it will prompt the user to check/uncheck the configuration.

  1. During the installation, the installer prompts us to enable Hyper-v Windows features.

Here we should ensure that all Hyper-v Windows features are enabled, and appropriate components are installed.

Once the configuration dialog box is checked, click 'Ok' to proceed with the installation.

  1. Once installation completes, the user is prompted to restart the machine.

We can click 'Close and restart' to restart the machine to complete the installation.

Once the Docker Desktop installation is successful, it does not start immediately. Instead, we can start Docker Desktop by clicking the related Icon from programs or clicking on the Docker Desktop shortcut. Once this is done, the following screen appears.

The above screenshot shows the 'Settings screen for the Docker Desktop'. Now that the Docker Desktop is installed successfully and running, we can access it from any terminal window.

  1. First, click the Windows Start menu, and select Settings > Apps > Apps & features.
  2. Now select/ choose Docker Desktop from the Apps & features list and then click Uninstall.
  3. Click Uninstall to confirm your selection.

Note: As a result of Docker Desktop uninstallation, the Docker containers and images local to the machine are destroyed and also remove the files generated by the application.

How to Install Docker on macOS?

Docker can be installed on macOS either using the HomeBrew package installer or downloading the package directly from the docker site. In this article, we will cover the details of how we can install the Docker on a macOS machine using the HomeBrew package:

Run the following command to install Docker using HomeBrew:

Once Docker will be successfully installed, it will show a success message as shown in the following image:

You can also validate the successful installation of Docker on macOS by checking the details in Docker Desktop, as shown below:

Once the Docker is running, you can use it for pulling any of the Docker images and spinning containers.

How to uninstall Docker on macOS?

You can run the following command to uninstall Docker from a Mac machine:

This will remove all the components from the machine.

Note: The Docker images will not remove from the machine.

Key Takeaways:

  • Docker supports almost all modern operating systems, and we can install using various package managers provided by the operating systems.
  • On Windows and macOS, Docker provides a desktop version as well that we can use to enable various settings and configurations for the Docker.

Initially, the inception of Docker containerization started out with Linux as its base platform. However, over the years, Docker and Microsoft have continuously grown their partnership, creating a conveniently consistent interface for building, shipping, and running applications without the usual dependence hurdles associated with virtual machines.

Though a huge number of enterprises are already using Docker on Windows platforms, there has been a number of subtle functionality disparities between Windows and Linux containers. However, Windows Server 2019 (1809 build) has successfully addressed most of the inconsistencies between Docker containers in Linux and Windows environments.

Requirements for Installation of Docker on Windows

Docker containers are powered by a Docker engine. Though initially designed for Linux, extensive work has been done to allow Docker containers to run on Windows and macOS environments.

To run Docker containers on a Windows platform, one prerequisite is the installation of a Windows server. You can do this in a physical server machine, on a cloud environment running in Azure, or an on-premise virtual machine.

Install the Hyper-V feature on your Windows server 2019

There are two distinct modes to run Decker containers on Windows platforms: Process isolation and Hyper-V isolation. With the Process isolation mode, the Docker containers share the OS kernel with the host platform, hence they are lightweight and identical to Linux system Docker containers.

On the other hand, the running of Docker containers in the Hyper-V mode is confined to a special nominal virtual machine. This enables improved compatibility and secure kernel-level. To run Docker containers in this mode, you must first enable Hyper-V in the host operating system.

The default operation mode for Docker installation on a Windows server is the operation mode (enabling Hyper-V is optional). However, it’s a prerequisite to enable the Hyper-V isolation mode if you need to run Linux containers on a Windows Server interface.

The OS build is another crucial determinant on the need for Hyper-V mode as Windows containers should be of the same build version as the container host OS’s version. Still, Windows container images with a lower build version than the container host OS can run with Hyper-V isolation.

To install Hyper-V on Windows Server 2019, run the PowerShell as Administrator and run the commands below:

Enable-WindowsOptionalFeature –Online -FeatureName Microsoft-Hyper-V –All -NoRestart

Install-WindowsFeature RSAT-Hyper-V-Tools -IncludeAllSubFeature

Next, restart your Windows Server VM.

Prerequisites for the container host

You must enable virtualization in the hosting Windows server platform to utilize Hyper-V isolation in your containers: enable hardware virtualization for a container host running on hardware and nested virtualization in the base interface for a container host running on a cloud space or Hyper-V.

Running Docker Containers on Windows Server 2019

Before running multiple isolated applications using Windows Containers, you need to activate (enable) the containers feature and install Docker on your Windows Server 2019. Here’s the process:

  1. Enable the containers feature in Windows Server 2019.

Run PowerShell as an Administrator and run this command:

Install-Module -Name DockerMsftProvider -Repository PSGallery -Force

This command will install the Docker-Microsoft Package Management Provider from the PowerShell Gallery.

When prompted to install and import NuGet provider, type Y and hit ENTER

  1. Install Docker on your Windows Server 2019

After installing the Containers feature on Windows Server 2019, it’s time to install the latest versions of Docker Engine and Docker Client. Run this command in your PowerShell session:

Install-Package -Name docker -ProviderName DockerMsftProvider

Accept the installation by selecting “Yes”, “Y” or “A” to Agree to all the installation requests.

After the completion of this installation, reboot your computer.

Restart-Computer –Force

You can check your installed Docker version via the PowerShell command:

Get-Package -Name Docker -ProviderName DockerMsftProvider

You can also confirm the installed Docker version using the docker –version command:

Download Docker Container Manually Free

docker –version

You can opt to upgrade anytime by running the commands below on PowerShell:

Install-Package -Name Docker -ProviderName DockerMsftProvider -Update -Force

Then start the docker service.

Start-Service Docker

  1. Launch (Run) Docker Containers on Windows Server 2019

Run the following commands on PowerShell:

Start-Service Docker

After starting the Docker Engine service, proceed to download the pre-created .NET sample image on the Docker Hub registry:

docker pull microsoft/dotnet-samples:dotnetapp-nanoserver-1809

After the download, you can deploy a simple Docker container that runs the .Net ‘Hello World’ application:

docker run microsoft/dotnet-samples:dotnetapp-nanoserver-1809

After running the command, an ASCII image will be printed to the shell accompanied by the “Hello” message.

Running Linux Containers on your Window Server 2019

By default, Docker on Windows only runs Windows containers. To launch Linux containers on Windows Server, use the Docker Enterprise Edition Preview that comes with a full LinuxKit system to run Docker Linux containers.

  1. First, uninstall the already installed Docker CE.

Uninstall-Package -Name docker -ProviderName DockerMSFTProvider

  1. Enable Nested Virtualization in case you’re running Docker Containers on a Linux Virtual Machine running on Hyper-V.

Download Docker Container Manually Windows 10

Get-VM WinContainerHost Set-VMProcessor -ExposeVirtualizationExtensions $true

NOTE:WinContainerHost is the name of your virtual machine

  1. Install the Module Docker Provider

Install-Module DockerProvider

Install-Package Docker -ProviderName DockerProvider -RequiredVersion preview

A restart will be required after this operation

  1. Enable LinuxKit system to run Linux containers

[Environment]::SetEnvironmentVariable(“LCOW_SUPPORTED”, “1”, “Machine”)

  1. Restart the Docker Service after the change above and restart the Service Docker

Restart-Service docker


To switch back to running Windows containers, execute the following command in PowerShell:

[Environment]::SetEnvironmentVariable(“LCOW_SUPPORTED”, “$null”, “Machine”)

You have finally installed and configured Docker your Windows Server machine to run both Linux and Windows containers. We hope this guide was insightful.
