Additional features such as a Kubernetes cluster and a vulnerability scanner are included. To use it, install docker-compose.ĭocker Desktop is a proprietary desktop application that runs the Docker Engine inside a Linux virtual machine. This is useful for setting up reoccuring services that are use often and/or have complex configurations. Docker Composeĭocker Compose is an alternate CLI frontend for the Docker Engine, which specifies properties of containers using a docker-compose.yml YAML file rather than, for example, a script with docker run options. Warning: Anyone added to the docker group is root equivalent because they can use the docker run -privileged command to start containers with root privileges. If you want to be able to run the docker CLI command as a non-root user, add your user to the docker user group, re-login, and restart rvice. # docker run -it -rm archlinux bash -c "echo hello world" The following command downloads the latest Arch Linux image and uses it to run a Hello World program within a container: Next, verify that you can run containers. You can also try to deconflict the networks (see solutions or ). You may reconnect the VPN immediately afterwards. If this is the case, try disconnecting the VPN before starting the docker service. Note that starting the docker service may fail if you have an active VPN connection due to IP conflicts between the VPN and Docker's bridge and overlay networks. Next enable/start rvice and verify operation: Install the docker package or, for the development version, the docker-git AUR package. The Docker Engine includes a daemon to manage the containers, as well as the docker CLI frontend. To pull Docker images and run Docker containers, you need the Docker Engine. Please do share your feedback and queries in the below comments section.Docker is a utility to pack, ship and run any application as a lightweight container. That’s all from this guide,I hope you have found it informative and useful. In case you are done with docker testing and want to remove docker from your system completely then run following commands to uninstall it, $ sudo apt purge docker-ce docker-ce-cli containerd.io \ĭocker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras -y To allow local user to run docker commands without sudo, add the user to docker group (secondary group) using usermod command. 5) Allow Local User to Run Docker Command In order to spin up ‘hello-world’ container, run below docker command with sudo $ sudo docker run hello-worldĪbove informational message confirms that docker is working properly. To verify the docker installation, try to spin up a ‘ hello-world’ container and see whether informational message is displayed or not. $ sudo systemctl start docker 4) Verify Docker Installation In case docker service is not running then try to start its service using beneath command. Verify its version and service status by running, $ sudo docker versionĪbove output confirm that, docker service is up and running. Once the docker is installed successfully then it’s service starts automatically. $ sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y Now it’s time to install Docker itself, run the following apt commands to install docker engine, $ sudo apt update Sudo tee /etc/apt//docker.list > /dev/null etc/os-release & echo "$VERSION_CODENAME")" stable" | \ Next, run echo command to add official docker repository. $ sudo chmod a+r /etc/apt/keyrings/docker.gpg $ curl -fsSL | sudo gpg -dearmor -o /etc/apt/keyrings/docker.gpg $ sudo install -m 0755 -d /etc/apt/keyrings To add docker repository, let’s first add Docker’s GPG key via following curl command. $ sudo apt install -y ca-certificates curl gnupg 2) Add Docker Repository Login to your Debian 12 system, open the terminal and run below command to update apt package index $ sudo apt update
