Docker-compose — это утилита, позволяющая запускать одновременно несколько контейнеров, используя при этом единый файл конфигурации всего стека сервисов, нужных вашему приложению. Например, такая ситуация: запускаем node.js webapp, которому нужна для работы mongodb, compose выполнит build вашего контейнера с webapp (традиционный Dockerfile) и перед его запуском запустит контейнер с mongodb внутри; так же может выполнить линк их между собой. Что крайне удобно как в разработке, так и в CI самого приложения. Так сложилось, что Windows пользователи были обделены возможностью использовать столько удобное средство, ввиду того, что официальной поддержки данной ОС все еще нет. А python версия для *nix не работает в окружении windows cmd, ввиду ограничений консоли Windows.
Для того, чтобы запустить docker-compose, мы можем использовать консольную оболочку Babun. Это, так сказать, «прокаченный» форк cygwin.
Итак, рецепт запуска docker-compose в Windows из консоли babun такой:
1. Скачиваем(~280MB!) и устанавливаем сам babun, узнать больше об этой оболочке можно на ее домашней странице babun.github.io;
2. Распаковываем архив (после установки полученную папку можно удалять);
3. Запускаем файл install.bat и ждем, пока пройдет установка;
4. После в открывшемся окне babun введем команду:
babun update
И убедимся, что у нас самая последняя версия оболочки (далее все команды выполняются только внутри оболочки babun);
5. Если вам не нравится дефолтный shell babun (используется zsh), его можно изменить на bash. Для этого вводим:
babun shell /bin/bash
6. Теперь нам нужно установить те самые зависимости Python, которых так не хватает docker-compose. Для этого выполним следующие команды по очереди:
pact install python-setuptools
pact install libxml2-devel libxslt-devel libyaml-devel
curl -skS https://bootstrap.pypa.io/get-pip.py | python
pip install virtualenv
curl -skS https://raw.githubusercontent.com/mitsuhiko/pipsi/master/get-pipsi.py | python
7. Теперь мы готовы установить сам docker-compose:
pip install -U docker-compose
Если все прошло успешно, увидим:
{ ~ } » docker-compose --version
docker-compose 1.2.0
Если же вы получили ошибку, error python fcntl или сообщение о не найдом файле docker-compose, попробуйте найти файл docker-compose в папках /usr/local/bin, /usr/sbin и подобных, затем можно сделать симлинк на /bin/. либо добавить в системный PATH недостающий путь.
Для правильной работы docker-compose нужно иметь уже настроенное окружение консоли для работы с docker-machine или boot2docker, а так же сам клиент docker должен быть доступен в системном PATH. О том, что такое docker, docker-machine и как с ними работать отлично рассказывает официальная документация.
Для входа в окружение нашего хоста докера, запущенного в docker-machine, нужно выполнить:
eval "$(docker-machine env ИМЯ_МАШИНЫ)"
Либо тоже самое для boot2docker:
eval "$(boot2docker shellinit)"
Проверить правильность работы клиента docker можно так:
docker ps
Если получаем список контейнеров или просто заголовки таблицы, значит, все ок!
docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
Для запуска стека приложения переходим в каталог нашего приложения, где у нас уже должен быть заготовлен файл docker-compose.yml или fig.yml. Синтаксис yml файла описан тут.
Далее для запуска вводим команду:
docker-compose up
Если нужно запустить в фоне, добавляем -d. Compose построит нужный образ и запустит его согласно вашему файлу docker-compose.yml.
На этом все.
Спасибо за внимание, надеюсь было полезно.
p.s. Я умышлено не стал говорить о варианте запуска compose как контейнера, т.к. считаю его неудобным.
Update 2021: docker-compose has been rewritten in Go, and is now a docker command docker compose
As such, there is no longer the need to «install» it.
See docker compose
.
Update 7th of november 2018:
On desktop systems like Docker for Mac and Windows, Docker Compose is
included as part of those desktop installs.
Accordingly to the documentation, Docker for Windows and Docker Toolbox already include Compose along with other Docker apps, so most Windows users do not need to install Compose separately.
Update 2017: this is now officially managed (for Windows 10 supporting Hyper-V) with «Docker for Windows».
See «Install Docker for Windows».
It does have a chocolatey installation package for Docker, so:
choco install docker-for-windows
# or
choco upgrade docker-for-windows
Again, this requires a 64bit Windows 10 Pro, Enterprise and Education (1511 November update, Build 10586 or later) and Microsoft Hyper-V.
For other Windows, you still need VirtualBox + Boot2Docker.
Update: docker compose 1.5 (Nov 2015) should make it officially available for Windows (since RC2).
Pull requests like PR 2230 and PR 2143 helped.
Commit 13d5efc details the official Build process for the Windows binary.
Original answer (Q1-Q3 2015).
Warning: the original answer («docker-compose
in a container») below seems to have a bug, according to Ed Morley (edmorley
).
There appear to be caching issues with the «docker-compose in a container» method (See issue #6: «Changes to docker-compose.yml and Dockerfile not being detected»)
Ed recommends:
As such for now, running the Python
docker-compose
package insideboot2docker
seems to be the most reliable solution for Windows users (having spent many hours trying to battle with the alternatives).To install docker-compose from PyPI, run this from inside
boot2docker
:docker@boot2docker:~$ tce-load -wi python && curl https://bootstrap.pypa.io/get-pip.py | \ sudo python - && sudo pip install -U docker-compose
To save having to run the above every time the
boot2docker
VM is restarted (since changes don’t persist), you can usebootlocal.sh
like so:docker@boot2docker:~$ echo 'su docker -c "tce-load -wi python" && \ curl https://bootstrap.pypa.io/get-pip.py | \ python - && pip install -U docker-compose' | \ sudo tee /var/lib/boot2docker/bootlocal.sh > /dev/null && \ sudo chmod +x /var/lib/boot2docker/bootlocal.sh
(The
su docker -c
gymnastics are required sincetce-load
cannot be run asroot
, andbootlocal.sh
is run asroot
. Thechmod
ofbootlocal.sh
should be unnecessary once #915 is fixed.
Add-a
to thetee
command if you need to append, rather than overwritebootlocal.sh
.)If you wish to use a pre-release version of docker-compose, then replace
pip install -U docker-compose
withpip install -U docker-compose>=1.3.0rc1
or equivalent.
Original answer:
I also run docker-compose
(on Windows boot2docker) in a image by:
-
cloning https://github.com/docker/compose in
/c/Users/<username>/myproject/compose
(in order to have persistence, since/c/Users/<username>
is automatically mounted, when I use VirtualBox with its extension pack ) -
building the docker-compose image:
cd /c/Users/<username>/myproject/compose # that will put the repo in a detached HEAD, but it does not matter here git checkout 1.2.0 docker build -t docker-compose .
-
adding a ‘
dc
‘ alias (in aprofile
file that I copy to my/home/docker/.ashrc
before launching the boot2docker ssh session.)dc='docker run --rm -i -t -v /var/run/docker.sock:/var/run/docker.sock -v `pwd`:`pwd` -w `pwd` docker-compose'
From there, a ‘dc up
‘ or ‘dc ps
‘ just works. On Windows. With boot2docker 1.6.
How to Install Docker Compose on Windows Server 2016 / 2019 / 2022. In this tutorial we will introduce Docker with it’s main advantages then move onto installation phase on Windows server.
Imagine a situation where you want to use two containers in a single system. In such a case, building, running and connecting the container from separate Docker files can be very difficult. It will take a lot of your time and even affect your productivity. That is why you need to consider Docker Compose.
What Is Docker Compose?
A Docker tool used for defining and running multi container Docker applications. Every container running on this platform is isolated. However, they can interact with each other as and when needed.
Moreover, Docker Compose files are written in an easy scripting language called YAML. An XML based language whose acronym is Yet Another Markup Language. What makes this tool highly popular among users is its feature of providing access to activate all the services using a single command.
In a nutshell, instead of containing all the services in a huge container, Docker Compose splits them up into individually manageable containers. It proves to be highly advantageous both for building and deployment as you can manage all of them in distinct codebases.
You can use a Docker Compose in three processes:
- Firstly to build component images using Docker Files, or get them from the libraries.
- Secondly to determine every component service in the “docker-compose.yml” files.
- Lastly to run them together via “docker-compose” CLI.
Docker Compose Features
Docker Compose constitutes the following features:
- Supporting Environment Variables -here the Docker Compose enables you to customize containers based on different environments or users by adding variables in the Docker Compose files. This way, you tend to get more flexibility while setting up containers with Compose. Interestingly you can use this feature for almost anything from securely providing passwords to specifying a software version.
- Reusing Existing Containers – where Docker Compose recreates containers that have changed since the last run. If it notices no changes, it re uses the existing container. It relies on the ability of the software to cache container configuration, thereby allowing you to set up your services faster.
- Volume Data Preservation – with Docker Compose it saves data used by the services. You do not have to worry about losing data created in containers. If you have containers from the previous run, it will find them and copy their volumes to the new run.
Advantages Of Docker Compose
Some of the crucial benefits of Docker Compose are as follows:
- Immediate And Straightforward Configurations – Since Docker Compose uses YAML scripts and environment variables, configuring and modifying application services is very effortless.
- Provides Portability And CI/CD Support – All the services are defined inside of the Docker Compose files, making it effortless for developers to access and share the entire configuration. If they pull the YAML files and source code, an environment can be launched in just a matter of minutes. This way, setting and enabling CI/CD pipelines is very easy.
- Internal Communication Security – With the help of Docker Compose, you can create a network for all the services to share. It adds an extra security layer for the app as the services cannot be accessed externally.
- Using Resources Efficiently -by using Docker Compose, you can host multiple environments on one host. When you run everything on a single piece of hardware, you save a lot of resources. This way, it can cache configuration and re use existing containers contributing to resource efficiency.
Follow this post to show you how to install Docker Compose on Windows Server 2016, 2019 and 2022.
Install Docker Compose on Windows Server 2016, 2019 and 2022

Create a Sample IIS Container with Docker Compose
To use Docker Compose, you will need to create a docker-compose.yml file where you can define your all applications, interconnect all with each other and run them using a single command.
Let’s create a docker-compose.yml file to launch a simple IIS container. To do so, open your Notepad++ editor and add the following configurations:
version: "2.1"
services:
iis-demo:
build: .
image: "iis-demo:1.0"
ports:
- "80"
networks:
nat:
ipv4_address: 172.24.128.2
volumes:
- "c:/temp:c:/inetpub/logs/LogFiles"
environment:
- "env1=LIVE1"
- "env2=LIVE2"
- "HOSTS=1.2.3.4:TEST.COM"
networks:
nat:
external: true
Save the file with name docker-compose.yml.
Next step is to create a Docker file using the Notepad++ editor using the following content:
FROM microsoft/iis
# install ASP.NET 4.5
RUN dism /online /enable-feature /all /featurename:IIS-ASPNET45 /NoRestart
# enable windows eventlog
RUN powershell.exe -command Set-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Control\WMI\Autologger\EventLog-Application Start 1
# set IIS log fields
RUN /windows/system32/inetsrv/appcmd.exe set config /section:system.applicationHost/sites /siteDefaults.logFile.logExtFileFlags:"Date, Time, ClientIP, UserName, SiteName, ServerIP, Method, UriStem, UriQuery, HttpStatus, Win32Status, TimeTaken, ServerPort, UserAgent, Referer, HttpSubStatus" /commit:apphost
# deploy webapp
COPY publish /inetpub/wwwroot/iis-demo
RUN /windows/system32/inetsrv/appcmd.exe add app /site.name:"Default Web Site" /path:"/iis-demo" /physicalPath:"c:\inetpub\wwwroot\iis-demo"
# set entrypoint script
ADD SetHostsAndStartMonitoring.cmd \SetHostsAndStartMonitoring.cmd
ENTRYPOINT ["C:\\SetHostsAndStartMonitoring.cmd"]
# declare volumes
VOLUME ["c:/inetpub/logs/LogFiles"]
Save the file with name Dockerfile.
Following step is to open your PowerShell as a administrator and change the directory to the directory where your docker-compose.yml and Dockerfile are saved.
Now run the following command to download IIS image and start the container:
Once the IIS container is started, you can verify the running container using the following command:
To check the container logs, run the following command:
If you want to stop the IIS container, run the following command:
That is great! We have learned How to Install Docker Compose on Windows Server 2016 / 2019 / 2022. it is time to summarize.
How to install Docker Compose on Windows Server 2016, 2019 and 2022 Conclusion
In this post, we explained how to install Docker Compose on Windows server 2016, 2019 and 2022. We also explained how to create a Docker file and docker-compose.yml file to launch the IIS demo container. I hope you can now easily launch your container using Docker Compose on Windows machine.
Docker Compose is very useful tool that make it easier orchestrate multiple containers to work together, especially in the case where you need to orchestrate more complex applications with multiple services. Docker compose also helps developers to automate the deployment of their code.
Please take a look at our Docker content here.
This page contains information on how to install Docker Compose. You can run Compose on macOS, Windows, and 64-bit Linux.
Prerequisites
Docker Compose relies on Docker Engine for any meaningful work, so make sure you have Docker Engine installed either locally or remote, depending on your setup.
-
On desktop systems like Docker Desktop for Mac and Windows, Docker Compose is included as part of those desktop installs.
-
On Linux systems, you can install Docker Compose with the Docker Engine using the convenience script. Select the install Docker Engine page for your distribution and then look for instructions on installing using the convenience script.
Otherwise, you should first install the Docker Engine for your OS and then refer to this page for instructions on installing Compose on Linux systems. -
To run Compose as a non-root user, see Manage Docker as a non-root user.
Install Compose
Follow the instructions below to install Compose on Mac, Windows, Windows Server, or Linux systems.
Install a different version
The instructions below outline installation of the current stable release (v2.5.0) of Compose. To install a different version of Compose, replace the given release number with the one that you want.
Compose releases are also listed and available for direct download on the Compose repository release page on GitHub.
To install the Python version of Compose, follow instructions in the Compose v1 GitHub branch.
- Mac
- Windows
- Windows Server
- Linux
- Linux Standalone binary
Install Compose on macOS
Docker Desktop for Mac includes Compose along with 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 Compose along with other Docker apps, so most Windows users do not need to install Compose separately. For install instructions, see Install Docker Desktop on Windows.
If you are running the Docker daemon and client directly on Microsoft Windows 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 directly on Microsoft Windows Server and want to install Docker Compose.
-
Start an “elevated” PowerShell (run it as administrator). Search for PowerShell, right-click, and choose Run as administrator. When asked if you want to allow this app to make changes to your device, click Yes.
-
In PowerShell, since GitHub now requires TLS1.2, run the following:
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
Then run the following command to download the current stable release of Compose (v2.5.0):
Invoke-WebRequest "https://github.com/docker/compose/releases/download/v2.5.0/docker-compose-Windows-x86_64.exe" -UseBasicParsing -OutFile $Env:ProgramFiles\Docker\docker-compose.exe
Note
On Windows Server 2019, you can add the Compose executable to
$Env:ProgramFiles\Docker
. Because this directory is registered in the systemPATH
, you can run thedocker-compose --version
command on the subsequent step with no additional configuration.To install a different version of Compose, substitute
v2.5.0
with the version of Compose you want to use. -
Test the installation.
$ docker compose version Docker Compose version v2.5.0
Install Compose on Linux systems
You can install Docker Compose in different ways, depending on your needs:
- In testing and development environments, some users choose to use automated convenience scripts to install Docker.
- Most users set up Docker’s repositories and install from them, for ease of installation and upgrade tasks. This is the recommended approach.
- Some users download and install the binary, and manage upgrades manually.
Install using the convenience script
As Docker Compose is now part of the Docker CLI it can be installed via a convenience script with Docker Engine and the CLI.
Choose your Linux distribution and follow the instructions.
Install using the repository
If you already follow the instructions to install Docker Engine, Docker Compose should already be installed.
Otherwise, you can set up the Docker repository as mentioned in the Docker Engine installation, choose your Linux distribution and go to the Set up the repository
section.
When finished
-
Update the
apt
package index, and install the latest version of Docker Compose, or go to the next step to install a specific version:$ sudo apt-get update $ sudo apt-get install docker-compose-plugin
-
To install a specific version of Docker Engine, list the available versions in the repo, then select and install:
a. List the versions available in your repo:
$ apt-cache madison docker-compose-plugin docker-compose-plugin | 2.3.3~ubuntu-focal | https://download.docker.com/linux/ubuntu focal/stable arm64 Packages
b. Install a specific version using the version string from the second column, for example,
2.3.3~ubuntu-focal
.$ sudo apt-get install docker-compose-plugin=<VERSION_STRING>
-
Verify that Docker Compose is installed correctly by checking the version.
$ docker compose version Docker Compose version v2.3.3
Install the binary manually
On Linux, you can download the Docker Compose binary from the Compose repository release page on GitHub and copying it into $HOME/.docker/cli-plugins
as docker-compose
. Follow the instructions from the link, which involve running the curl
command in your terminal to download the binaries. These step-by-step instructions are also included below.
-
Run this command to download the current stable release of Docker Compose:
$ DOCKER_CONFIG=${DOCKER_CONFIG:-$HOME/.docker} $ mkdir -p $DOCKER_CONFIG/cli-plugins $ curl -SL https://github.com/docker/compose/releases/download/v2.5.0/docker-compose-linux-x86_64 -o $DOCKER_CONFIG/cli-plugins/docker-compose
This command installs Compose for the active user under
$HOME
directory. To install Docker Compose for all users on your system, replace~/.docker/cli-plugins
with/usr/local/lib/docker/cli-plugins
.To install a different version of Compose, substitute
v2.5.0
with the version of Compose you want to use. -
Apply executable permissions to the binary:
$ chmod +x $DOCKER_CONFIG/cli-plugins/docker-compose
or if you choose to install Compose for all users
$ sudo chmod +x /usr/local/lib/docker/cli-plugins/docker-compose
-
Test the installation.
$ docker compose version Docker Compose version v2.5.0
Install Compose as standalone binary on Linux systems
You can use Compose as a standalone binary without installing the Docker CLI.
- Run this command to download the current stable release of Docker Compose:
$ curl -SL https://github.com/docker/compose/releases/download/v2.5.0/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose
To install a different version of Compose, substitute
v2.5.0
with the version of Compose you want to use.
- Apply executable permissions to the binary:
$ sudo chmod +x /usr/local/bin/docker-compose
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.For example:
$ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
-
Test the installation.
$ docker-compose --version Docker Compose version v2.5.0
Uninstallation
To uninstall Docker Compose if you installed using curl
:
$ rm $DOCKER_CONFIG/cli-plugins/docker-compose
or if you choose to install Compose for all users
$ sudo rm /usr/local/lib/docker/cli-plugins/docker-compose
Got a “Permission denied” error?
If you get a “Permission denied” error using either of the above methods, you probably do not have the proper permissions to remove
docker-compose
. To force the removal, prependsudo
to either of the above commands and run again.

Introduction
Installing docker-compose
on Windows requires a few steps. Here’s a step-by-step guide that should help you get set up:
- Step 1 — Install Docker for Windows
To use docker-compose
, you’ll first need to have Docker installed on your Windows machine. If you don’t have it installed already, you can download it from the Docker website:
- Go to the Docker website (https://www.docker.com/products/docker-desktop)
- Click on the «Get Docker» button to download the installer
- Run the installer and follow the prompts to complete the installation
Once Docker is installed, you should be able to open the Docker application from the Windows Start menu and see the Docker daemon running. This is an important step, as docker-compose
relies on the Docker engine to work.
- Step 2 — Install Docker Compose
After installing Docker, you can proceed to install docker-compose
. You have a few different options for doing this, depending on your setup and preferences. Here are two methods you can use:
Method 1: Download the docker-compose
binary
- Go to the
docker-compose
releases page on GitHub (https://github.com/docker/compose/releases) - Download the
docker-compose-Windows-x86_64.exe
file for the latest release. - Move the downloaded executable file to a directory in your system’s PATH. This can be done by creating a new directory in
C:\Program Files\
and adding the directory path to the PATH environment variable.
Method 2: Use pip to install docker-compose
- Install python by downloading the installer from https://www.python.org/downloads/ and run the installer,
- add python executable to your system PATH by checking the «Add Python to PATH» checkbox on the first step of the installer.
- Open the command prompt and type
pip install docker-compose
After you have installed docker-compose
, you should be able to run the docker-compose
command from the command prompt or PowerShell to see the version of docker-compose
installed and check if it’s working properly.
- Step 3 — Verify the installation
To verify that docker-compose
is installed and working properly, you can run the following command:
This should print the version of docker-compose
that you have installed, along with some other information. If you see an error message instead, then the installation may not have been successful, and you should check the error message to see what went wrong.
That’s it! You should now have docker-compose
installed on your Windows machine and be able to use it to run multi-container applications.
Keep in mind that, this is just a basic introduction, and to learn more about docker-compose
and how to use it, you can check the official documentation.
- Step 4 — Using
docker-compose
Now that you have docker-compose
installed, you can use it to start, stop and manage multi-container applications.
A docker-compose.yml
file is used to define the services, networks and volumes for your application. It’s a YAML file that describes the services, networks and volumes needed for your application. Here’s an example docker-compose.yml
file that defines a simple web application with a web service and a redis service:
version: '3'
services:
web:
build: .
ports:
- "8000:8000"
volumes:
- .:/code
depends_on:
- redis
redis:
image: redis
Once you have a docker-compose.yml
file, you can use the docker-compose
command to start, stop and manage your application. Here are a few examples of common docker-compose
commands you might use:
docker-compose up
— start the services defined in thedocker-compose.yml
filedocker-compose down
— stop the services and remove the containers, networks, and volumes defined in thedocker-compose.yml
filedocker-compose ps
— show the status of the services defined in thedocker-compose.yml
filedocker-compose logs
— show the logs for the services defined in thedocker-compose.yml
filedocker-compose exec
— execute a command in a running container
These are just a few examples of the commands you can use with docker-compose
, there are many more options and capabilities that you can explore and use to manage your multi-container applications.
Conclusion
In conclusion, docker-compose
is a powerful tool that allows you to easily manage multi-container applications on a Windows machine. The process of installing it requires a few steps, including having Docker installed first. Once you have docker-compose
installed, you can use the docker-compose
command along with a docker-compose.yml
file to start, stop, and manage your application.
It’s a good idea to take a look at the official documentation to explore other options and capabilities of docker-compose
as well as to explore some examples of real-world usage. As a beginner, it might take some time for you to get used to the concepts and commands, but with time and practice, you will get more comfortable and confident with it.
