To install Docker on Linux, you can follow the official documentation for your specific distribution. Generally, the steps involve adding the Docker repository, installing the Docker engine, and configuring Docker to start on boot.
Once Docker is installed, you can use various tools to manage containers, such as Docker Compose, Docker Swarm, and Kubernetes. Docker Compose is used to define and run multi-container applications, while Docker Swarm and Kubernetes are used to orchestrate container clusters.
To install these tools, you can follow their respective documentation, which usually involves downloading the binary and adding it to your system path. Once installed, you can use these tools to manage and scale your containerized applications.
To install Docker on Debian/Ubuntu, you can follow these steps:
sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates curl gnupg lsb-release
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
sudo docker run hello-world
That’s it! Docker should now be installed on your Debian/Ubuntu system.
To install Docker Compose on Debian, you can follow these steps:
sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version
That’s it! Docker Compose should now be installed on your Debian system. You can now use it to define and run multi-container Docker applications.
