Docker Compose is used to run multiple containers as a single service. For example, suppose you had an application which required NGNIX and MySQL, you could create one file which would start both the containers as a service without the need to start each one separately. Install Compose on Linux systems. On Linux, you can download the Docker Compose binary from the Compose repository release page on GitHub.Follow the instructions from the link, which involve running the curl command in your terminal to download the binaries. Use Docker Compose. Estimated reading time: 11 minutes. Docker Compose is a tool that was developed to help define and share multi-container applications. With Compose, we can create a YAML file to define the services and with a single command, can spin everything up or tear it all down.

In the introductory chapters, we have seen the installation of Docker toolbox on Windows. The Docker toolbox is developed so that Docker containers can be run on Windows and MacOS. The site for toolbox on Windows is https://docs.docker.com/docker-for-windows/

Docker

For Windows, you need to have Windows 10 or Windows Server 2016 with Hyper-V enabled.

The toolbox consists of the following components −

  • Docker Engine − This is used as the base engine or Docker daemon that is used to run Docker containers.

  • Docker Machine − for running Docker machine commands.

  • Docker Compose for running Docker compose commands.

  • Kinematic − This is the Docker GUI built for Windows and Mac OS.

  • Oracle virtualbox

Let’s now discuss the different types of activities that are possible with Docker toolbox.

Running in Powershell

With Docker toolbox on Windows 10, you can now run Docker commands off powershell. If you open powershell on Windows and type in the command of Docker version, you will get all the required details about the Docker version installed.

Pulling Images and Running Containers

You can also now pull Images from Docker Hub and run containers in powershell as you would do in Linux. The following example will show in brief the downloading of the Ubuntu image and running of the container off the image.

The first step is to use the Docker pull command to pull the Ubuntu image from Docker Hub.

The next step is to run the Docker image using the following run command −

You will notice that the command is the same as it was in Linux.

Kitematic

This is the GUI equivalent of Docker on Windows. To open this GUI, go to the taskbar and on the Docker icon, right-click and choose to open Kitematic.

It will prompt you to download Kitematic GUI. Once downloaded, just unzip the contents. There will be a file called Kitematic.exe. Double-click this exe file to open the GUI interface.

You will then be requested to log into Docker Hub, enter through the GUI. Just enter the required username and password and then click the Login button.

Once logged in, you will be able to see all the images downloaded on the system on the left-hand side of the interface.

On the right-hand side, you will find all the images available on Docker Hub.

Let’s take an example to understand how to download the Node image from Docker Hub using Kitematic.

Step 1 − Enter the keyword of node in the search criteria.

Step 2 − Click the create button on official Node image. You will then see the image being downloaded.

Once the image has been downloaded, it will then start running the Node container.

Step 3 − If you go to the settings tab, you can drill-down to further settings options, as shown below.

  • General settings − In this tab, you can name the container, change the path settings, and delete the container.

  • Ports − Here you can see the different port mappings. If you want, you can create your own port mappings.

  • Volumes − Here you can see the different volume mappings.

  • Advanced − It contains the advanced settings for the container.
