Docker is a platform for running applications in an isolated environment called a 'container' (or Docker container). Applications like Jenkins can be downloaded as read-only 'images' (or Docker images), each of which is run in Docker as a container. A Docker container is in effect a 'running instance' of a Docker image.
Once you have installed Docker Desktop for Windows, you will find the Docker icon in your system tray. You can right click, and access the menu to change some of the settings. As you can see from screen below, we are currently running Linux containers, and can switch to Windows container by clicking the menu option. If you are using the docker-slim container make sure you run it configured with the Docker IPC information, so it can communicate with the Docker daemon. The most common way to do it is by mounting the Docker unix socket to the docker-slim container. In case of Docker Container, since the container runs on your host OS, you can save precious boot-up time. This is a clear advantage over Virtual Machine. Consider a situation where I want to install two different versions of Ruby on my system.

Docker Desktop for Mac is the Community version of Docker for Mac.You can download Docker Desktop for Mac from Docker Hub.
By downloading Docker Desktop, you agree to the terms of the Docker Software End User License Agreement and the Docker Data Processing Agreement.
Your Mac must meet the following requirements to successfully install Docker Desktop:
macOS must be version 10.14 or newer. That is, Mojave, Catalina, or Big Sur. We recommend upgrading to the latest version of macOS.
If you experience any issues after upgrading your macOS to version 10.15, you must install the latest version of Docker Desktop to be compatible with this version of macOS.
Docker supports Docker Desktop on the most recent versions of macOS. That is, the current release of macOS and the previous two releases. As new major versions of macOS are made generally available, Docker stops supporting the oldest version and supports the newest version of macOS (in addition to the previous two releases). Docker Desktop currently supports macOS Mojave, macOS Catalina, and macOS Big Sur.
At least 4 GB of RAM.
VirtualBox prior to version 4.3.30 must not be installed as it is not compatible with Docker Desktop.

You can run Compose on macOS, Windows, and 64-bit Linux.
Docker Compose relies on Docker Engine for any meaningful work, so make sure youhave Docker Engine installed either locally or remote, depending on your setup.
On desktop systems like Docker Desktop for Mac and Windows, Docker Compose isincluded as part of those desktop installs.
On Linux systems, first install theDocker Enginefor your OS as described on the Get Docker page, then come back here forinstructions on installing Compose onLinux systems.
To run Compose as a non-root user, see Manage Docker as a non-root user.
Follow the instructions below to install Compose on Mac, Windows, Windows Server2016, or Linux systems, or find out about alternatives like using the
pipPython package manager or installing Compose as a container.
Install a different version
The instructions below outline installation of the current stable release(v1.28.6) of Compose. To install a different version ofCompose, replace the given release number with the one that you want. Composereleases are also listed and available for direct download on theCompose repository release page on GitHub.To install a pre-release of Compose, refer to the install pre-release buildssection.
Install Compose on macOS
Docker Desktop for Mac includes Compose alongwith other Docker apps, so Mac users do not need to install Compose separately.For installation instructions, see Install Docker Desktop on Mac.
Install Compose on Windows desktop systems
Docker Desktop for Windows includes Composealong with other Docker apps, so most Windows users do not need toinstall Compose separately. For install instructions, see Install Docker Desktop on Windows.
If you are running the Docker daemon and client directly on MicrosoftWindows Server, follow the instructions in the Windows Server tab.
Install Compose on Windows Server
Follow these instructions if you are running the Docker daemon and client directlyon Microsoft Windows Server and want to install Docker Compose.
Install Docker Container On Windows
Start an “elevated” PowerShell (run it as administrator).Search for PowerShell, right-click, and chooseRun as administrator. When asked if you want to allow this appto make changes to your device, click Yes.
In PowerShell, since GitHub now requires TLS1.2, run the following:
Then run the following command to download the current stable release ofCompose (v1.28.6):
Note: On Windows Server 2019, you can add the Compose executable to
$Env:ProgramFilesDocker. Because this directory is registered in the system
PATH, you can run the
docker-compose --version command on the subsequent step with no additional configuration.
Test the installation.
Install Compose on Linux systems
On Linux, you can download the Docker Compose binary from theCompose repository release page on GitHub.Follow the instructions from the link, which involve running the
curl commandin your terminal to download the binaries. These step-by-step instructions arealso included below.
alpine, the following dependency packages are needed:
Run this command to download the current stable release of Docker Compose:
To install a different version of Compose, substitute
1.28.6with the version of Compose you want to use.
If you have problems installing with
curl, seeAlternative Install Options tab above.
Apply executable permissions to the binary:
Note: If the command
docker-compose fails after installation, check your path.You can also create a symbolic link to
/usr/bin or any other directory in your path.
Optionally, install command completion for the
Test the installation.
Alternative install options
Install using pip
alpine, the following dependency packages are needed:
Compose can be installed frompypi using
pip. If you installusing
pip, we recommend that you use avirtualenv because many operatingsystems have python system packages that conflict with docker-composedependencies. See the virtualenvtutorial to getstarted.
Docker Container With Docker Installed
If you are not using virtualenv,
pip version 6.0 or greater is required.
Install as a container
Compose can also be run inside a container, from a small bash script wrapper. Toinstall compose as a container run this command:
Install pre-release builds
If you’re interested in trying out a pre-release build, you can download releasecandidates from the Compose repository release page on GitHub.Follow the instructions from the link, which involves running the
curl commandin your terminal to download the binaries.
Pre-releases built from the “master” branch are also available for download athttps://dl.bintray.com/docker-compose/master/.
Pre-release builds allow you to try out new features before they are released,but may be less stable.
If you’re upgrading from Compose 1.2 or earlier, remove ormigrate your existing containers after upgrading Compose. This is because, as ofversion 1.3, Compose uses Docker labels to keep track of containers, and yourcontainers need to be recreated to add the labels.
If Compose detects containers that were created without labels, it refusesto run, so that you don’t end up with two sets of them. If you want to keep usingyour existing containers (for example, because they have data volumes you wantto preserve), you can use Compose 1.5.x to migrate them with the followingcommand:
Debian Docker Image With Docker Installed
Alternatively, if you’re not worried about keeping them, you can remove them.Compose just creates new ones.

After you have installed docker on your linux machine, the next step is to create an image and run a container. You need to create a base image of an OS distribution and after that you can add and modify the base image by installing packages and dependencies and committing the changes to it.
In this article, we will show you how to create an ubuntu base image and on top of that create intermediate image layers by adding packages in it and keep committing the changes. We will update the ubuntu base image, install 3 packages - vim editor, firefox and python 3.
Note that we can do this using two ways - either we mention all the commands inside a dockerfile and build the image all at once or we can do it step by step and keep committing the changes through CLI. We will discuss both the methods here.
Method 1. Step by Step using CLI.
Open a terminal and run the following command. Note that if you are not the root user, you need to add sudo before all the commands.
Install Docker Container
This will check if an ubuntu image exists locally or not. If it does not exist, it will display “Unable to find image 'ubuntu:latest' locally” message and start pulling it from docker hub. After pulling the image, it will run the apt update command.
We will now install a vim editor inside the container. For that, we will run the bash of the ubuntu image.
This will open an interactive ubuntu bash. Inside the bash, type the following commands one by one to install the packages.
The first command runs an update. It then installs vim editor, firefox and some dependencies for python 3. Then it adds the official python 3 repository and installs python 3.7 and then exits the bash.
You can check the version of python using the following command.
After exiting the bash, you need to commit the changes. Find out the container ID using the following command.
Copy the container ID and paste in the following command.
You can check that the new ubuntu image with the specified name and installed packages has been created using the following command.
Method 2. By creating a dockerfile
Create a file name dockerfile and place the following commands in it.
Build the image using the following command.
This command builds the docker image using the dockerfile.
Run the docker image using the following command.
To conclude, the better method to create an image and install packages is by creating a dockerfile with the appropriate commands because it will help you to keep track of the changes that you make and the packages that you install and gives a better clarity of the whole project.
