Docker Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration. Compose is great for development, testing, and staging environments, as well as CI/CD pipelines.
If you’re looking for a way to run docker containers on your Raspberry Pi, you’ve come to the right place. In this blog post, we’ll show you how to install docker and docker-compose on your Raspberry Pi.
Installing Docker on Raspberry Pi
Docker can be installed on a Raspberry Pi in a few different ways. The easiest way is to use the HypriotOS image, which comes with Docker pre-installed. You can also install Docker on Raspbian, the official Raspberry Pi operating system.
Installing Docker on a Raspberry Pi is a great way to get started with container-based virtualization. Docker is easy to use and can help you package and deploy applications quickly and easily.
To install Docker on Raspberry Pi, follow these steps:
- First, update your Linux software database by running the following command
sudo apt-get update
- Once the update is completed, you can install Docker using its official installation script.
curl -sSL https://get.docker.com | sh
Installing Docker Compose on Raspberry Pi
docker-compose is the tool for defining and running multi-container Docker applications. In other words, it allows you to define and run multiple containers with a single command.
This is important for several reasons. First, it allows you to easily spin up and down multiple containers, this can be helpful when testing or developing new applications.
Second, docker-compose also allows you to define dependencies between containers, you’ll need it when you want one container to start up before another.
Overall, docker-compose is a powerful tool that can help developers more easily manage and run multi-container applications.
In order to install Docker Compose on Raspberry Pi, follow the instructions below:
First, install the latest version of
pip by running the following command:
sudo curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py && sudo python3 get-pip.py
Then, fetch and install docker-compose from apt repository using the command below.
sudo apt-get install docker-compose
Remember to add your user (in this example, named
pi) to the
docker group afterwards so that the Docker executable can access Unix sockets when needed. Run the following command to do that:
sudo usermod -aG docker pi
Once you’ve done, log out and log back in (or reboot) for the changes to take effect
You can verify that Docker and Docker Compose are installed properly by running these two commands:
docker -v docker-compose -v
The commands will print out the version and build number of both Docker and Docker-Compose, which should look something similar to this:
Code language: CSS (css)
Docker version 19.03.8, build afacb8b7f0 docker-compose version 1.25.5, build 8a1c60f6
