For more information, refer to > [Docker and ufw](../../network/packet-filtering-firewalls.md#docker-and-ufw). ### OS requirements To install Docker Engine, you need the 64-bit version of one of these Debian versions: - Debian Bookworm 12 (stable) - Debian Bullseye 11 (oldstable) Docker Engine for Debian is compatible with x86_64 (or amd64), armhf, arm64, and ppc64le (ppc64el) architectures. ### Uninstall old versions Before you can install Docker Engine, you must first make sure that any conflicting packages are uninstalled. Distro maintainers provide an unofficial distribution of Docker packages in their repositories. You must uninstall these packages before you can install the official version of Docker Engine. The unofficial packages to uninstall are: - `docker.io` - `docker-compose` - `docker-doc` - `podman-docker` Moreover, Docker Engine depends on `containerd` and `runc`. Docker Engine bundles these dependencies as one bundle: `containerd.io`. If you have installed the `containerd` or `runc` previously, uninstall them to avoid conflicts with the versions bundled with Docker Engine. Run the following command to uninstall all conflicting packages: ```console $ for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done ``` `apt-get` might report that you have none of these packages installed. Images, containers, volumes, and networks stored in `/var/lib/docker/` aren't automatically removed when you uninstall Docker. If you want to start with a clean installation, and prefer to clean up any existing data, read the [uninstall Docker Engine](#uninstall-docker-engine) section. ## Installation methods You can install Docker Engine in different ways, depending on your needs: - Docker Engine comes bundled with [Docker Desktop for Linux](../../desktop/install/linux-install.md). This is the easiest and quickest way to get started. - Set up and install Docker Engine from [Docker's `apt` repository](#install-using-the-repository). - [Install it manually](#install-from-a-package) and manage upgrades manually. - Use a [convenience scripts](#install-using-the-convenience-script). Only recommended for testing and development environments. ### Install using the apt repository {#install-using-the-repository} Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository. #### Set up the repository {% assign download-url-base = "https://download.docker.com/linux/debian" %} 1. Update the `apt` package index and install packages to allow `apt` to use a repository over HTTPS: ```console $ sudo apt-get update $ sudo apt-get install ca-certificates curl gnupg ``` 2. Add Docker's official GPG key: ```console $ sudo install -m 0755 -d /etc/apt/keyrings $ curl -fsSL {{ download-url-base }}/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg $ sudo chmod a+r /etc/apt/keyrings/docker.gpg ``` 3. Use the following command to set up the repository: ```console $ echo \ "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] {{ download-url-base }} \ "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/null ``` > **Note** > > If you use a derivative distro, such as Kali Linux, > you may need to substitute the part of this command that's expected to > print the version codename: > > ```console > $(. /etc/os-release && echo "$VERSION_CODENAME") > ``` #### Install Docker Engine 1. Update the `apt` package index: ```console $ sudo apt-get update ``` 2. Install Docker Engine, containerd, and Docker Compose.
