  • 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.
  • Docker Upgrade Container Tracking; Estimated reading time: 15 minutes. Docker’s run utility is the command that actually launches a container. Each container is an instance of an image.Containers are designed to be transient and temporary, but they can. Upgrade Kubernetes. Docker Desktop does not upgrade your Kubernetes cluster automatically.
  • Docker engine is the user engine, where the user can authorize his container part. Docker engine works with server host and client host. To install the Docker engine first, you need to update the apt of your Linux. For that, use the apt-update command from the terminal. Sudo apt-get update.
  • Install Docker Desktop. With the WSL 2 backend supported in Docker Desktop for Windows, you can work in a Linux-based development environment and build Linux-based containers, while using Visual Studio Code for code editing and debugging, and running your container in the Microsoft Edge browser on Windows.

Install Docker CE on Amazon Linux 2. Before we start the update, let’s ensure our system is updated. Sudo yum -y update. Once the update has been done, reboot your system. Sudo systemctl reboot. Wait for reboot to be completed then login back and continue with the installation of Docker CE on Amazon Linux 2.

Docker is an open-source containerization technology that is designed to create, deploy and run container-based applications. In this article, you will learn how to install the Docker Community Edition (CE) on Linux Mint 20.

If you have any older version of docker already installed in your machine you have to remove it.

Let’s get started…

How to Install Docker in Linux Mint

Now there are three ways you can install Docker in Linux Mint.

  1. Setting up docker repository.
  2. Download and install the .deb package locally.
  3. Using Docker installation script.

1. Install Docker Using Repository

Using this method we will add the Docker repository to the apt package manager index and will install the docker from there. By default apt will not support HTTPS, you have to enable it.

Now add GPG key for docker.

Now add the stable repository. As per the official documentation, if you use Linux Mint and if you face any installation issue then replace $(lsb_release -cs) with your parent Ubuntu distribution. In my case, my parent ubuntu distribution will be focal.

Linux Upgrade Docker

Update the repository and install the docker package using the below command.

2. Install Docker Manually Using Deb Package

In this method, we will download the .deb file and install it locally using the apt or dpkg command. Go to the docker index page from where you can download the .deb file. If you take a look at the below image there is no package for ulyana so I will download .deb from focal.

You can go inside “ubuntu/dists/focal/pool/stable/amd64/” and download .deb package for the Docker Engine version you wish to install.

Once you have downloaded the packages go inside the directory where the file is downloaded and run the following command.

3. Install Docker Using Installation Script

In this method, you will install docker using a shell script which will take care of installing docker in your machine. This script will try to install the latest version that is released under the edge channel. If you already have docker installed in your machine, running this script will cause issues. Run the following command to download and run the script.

How to Validate the Docker Installation

You can choose any of the three methods described in previous sections for installing docker. Once the installation is completed you can run the “hello-world” container to check if your installation is successful.

To check the docker version run the following command.

In Ubuntu-based distribution, docker will be automatically started and enabled to start during boot.

How to Run Docker as a Normal User

Instead of binding with TCP socket docker binds with Unix socket which is accessible only by root. If you wish not to use sudo every time to work with docker then you can create a group called docker and add non-root users into the group.

Now open a new terminal and run the hello-world container without sudo. From the below image you can see I am able to successfully run the container without sudo privilege.

That’s it for this article. If you have any feedback use the comment section.

Learn how to install Docker on Ubuntu in this easy to follow guide for beginners. Just follow the steps and start using Docker in a matter of minutes.

Docker is a platform that packages the application and all its dependencies in the container so that the application works seamlessly. It uses virtualization technology to provide isolated containers for software and tools. They are similar to virtual machines, but containers are more portable, and more resource-friendly.

This article will show you the easiest way to install Docker on Ubuntu and get it running.

Installing Docker on Ubuntu

Docker is available for installation from the standard Ubuntu repos, but it may not always be the latest version. To ensure we get the latest version, we’ll install Docker from the official Docker repository.

1. Update Packages

First, update the packages index and install the dependencies necessary to add a new HTTPS repository.

2. Add the Docker Repo

Next, import the GPG key for the official Docker repository to your system. This is a security feature to ensure that the software you’re installing is authentic.

In order to be able to install Docker on your Ubuntu system, you must first add the stable Docker APT repository to it:

Finally, update the package database with the Docker packages from the newly added repo:

3. Install Docker

To install the latest version of Docker on Ubuntu, run the command below.

Congratulations! Docker should now be installed, the service started and enabled to start on boot. In addition, you can check the Docker state using:

When a new version of Docker is released, you can just update the packages using the standard apt update procedure.

Enabling Non-root Users to Run Docker Commands

Linux Upgrade Docker Code

So far, we have successfully installed a Docker on your Ubuntu system.

By default, only root and user with sudo privileges can execute Docker commands. If you attempt to run the docker command without prefixing it with sudo, you’ll get an output like this:

To run Docker commands as a non-root user, you have to add your user to the docker group. To do that, type in:

In the command shown above, ${USER} is an environment variable that holds your username. To apply the new group membership, log out and back in.
