Docker auf Ubuntu Server installieren

Step 1 — Prepare the system for installation Before we can start installing docker & docker-compose we need to make sure that the system is up to date. You can do it by running the following commands:

sudo apt update sudo apt upgrade -y

Step 2 — Download and Install the docker repository Docker is using an installation repository. to install the repository and use it we need to install the following packages:

sudo apt install -y ca-certificates curl gnupg lsb-release

After the package installation, we need to add Docker’s GPG Key to our system by running the following commands:

sudo mkdir -p /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg –dearmor -o /etc/apt/keyrings/docker.gpg

Now we can install the docker repository by running the following commands:

sudo echo “deb [arch=$(dpkg –print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable” | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt update

Step 3 — Installing Docker You can proceed to install Docker by executing the provided command below. This straightforward command will enable you to initiate the Docker installation process on your system.

sudo apt install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

To install docker-compose tun the following commands:

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

To verify that your Docker Compose installation was successful, you can use the following command:

docker-compose –version

Running this command will display the version of Docker Compose that is currently installed on your system. If you see the version information, it means the installation was successful, and Docker Compose is ready for use.
