Save and close the docker-compose.yml file. Create a Django project. In this step, you create a Django starter project by building the image from the build context defined in the previous procedure. Change to the root of your project directory. Create the Django project by running the docker-compose run command as follows.
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. We’ll then use the docker client to deploy this to a Kubernetes cluster running the controller: $ docker stack deploy -orchestrator=kubernetes -c docker-compose.yml words Waiting for the stack to be stable and running. Db: Ready pod status: 1/1 ready, 0/1 pending, 0/1 failed web: Ready pod status: 1/1 ready, 0/1 pending, 0/1 failed. When using a docker-compose.yml and docker-compose.override.yml file, which both contain a port mapping, where the host port is the same for both mappings, but the container port differs, then this causes docker to try and allocate the host port twice.

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 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.
Install Compose
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.
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.
For alpine, the following dependency packages are needed:py-pip, python3-dev, libffi-dev, openssl-dev, gcc, libc-dev, rust, cargo and make.
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.
For example:
Optionally, install command completion for the
bashandzshshell.Test the installation.
Alternative install options
Install using pip
For alpine, the following dependency packages are needed:py-pip, python3-dev, libffi-dev, openssl-dev, gcc, libc-dev, rust, cargo, and make.
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.
If you are not using virtualenv,
pip version 6.0 or greater is required.
Install as a container
Running Docker Compose In Openshift
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.
Upgrading
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.
Running Docker Compose
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:
Alternatively, if you’re not worried about keeping them, you can remove them.Compose just creates new ones.
Uninstallation
To uninstall Docker Compose if you installed using curl:
To uninstall Docker Compose if you installed using pip:
Got a “Permission denied” error?
If you get a “Permission denied” error using either of the abovemethods, you probably do not have the proper permissions to removedocker-compose. To force the removal, prepend sudo to either of the abovecommands and run again.
