For a list of supported operating systems and distributions for different Docker editions, see [Docker variants](/engine/installation/#docker-variants). ### OS requirements To install Docker CE, you need the 64-bit version of one of these Debian or Raspbian versions: - Buster 10 (Docker CE 17.11 Edge only) - Stretch 9 (stable) / Raspbian Stretch - Jessie 8 (LTS) / Raspbian Jessie - Wheezy 7.7 (LTS) Docker CE is supported on both `x86_64` (or `amd64`) and `armhf` architectures for Jessie and Stretch. ### Uninstall old versions Older versions of Docker were called `docker` or `docker-engine`. If these are installed, uninstall them: ```bash $ sudo apt-get remove docker docker-engine docker.io ``` It's OK if `apt-get` reports that none of these packages are installed. The contents of `/var/lib/docker/`, including images, containers, volumes, and networks, are preserved. The Docker CE package is now called `docker-ce`. ### Extra steps for Wheezy 7.7 - You need at least version 3.10 of the Linux kernel. Debian Wheezy ships with version 3.2, so you may need to [update the kernel](https://wiki.debian.org/HowToUpgradeKernel){: target="_blank" class="_" }. To check your kernel version: ```bash $ uname -r ``` - Enable the `backports` repository. See the [Debian documentation](https://backports.debian.org/Instructions/){: target="_blank" class"_"}. ## Install Docker CE You can install Docker CE in different ways, depending on your needs: - Most users [set up Docker's repositories](#install-using-the-repository) and install from them, for ease of installation and upgrade tasks. This is the recommended approach, except for Raspbian. - Some users download the DEB package and [install it manually](#install-from-a-package) and manage upgrades completely manually. This is useful in situations such as installing Docker on air-gapped systems with no access to the internet. - In testing and development environments, some users choose to use automated [convenience scripts](#install-using-the-convenience-script) to install Docker. This is currently the only approach for Raspbian. ### Install using the repository Before you install Docker CE 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. > **Raspbian users cannot use this method!** > > For Raspbian, installing using the repository is not yet supported. You must > instead use the [convenience script](#install-using-the-convenience-script). #### Set up the repository {% assign download-url-base = 'https://download.docker.com/linux/$(. /etc/os-release; echo "$ID")' %} 1. Update the `apt` package index: ```bash $ sudo apt-get update ``` 2. Install packages to allow `apt` to use a repository over HTTPS:
```bash $ sudo apt-get install \ apt-transport-https \ ca-certificates \ curl \ gnupg2 \ software-properties-common ```
```bash $ sudo apt-get install \ apt-transport-https \ ca-certificates \ curl \ python-software-properties ```
3. Add Docker's official GPG key: ```bash $ curl -fsSL {{ download-url-base}}/gpg | sudo apt-key add - ``` Verify that you now have the key with the fingerprint `9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88`, by searching for the last 8 characters of the fingerprint. ```bash $ sudo apt-key fingerprint 0EBFCD88 pub 4096R/0EBFCD88 2017-02-22 Key fingerprint = 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 uid Docker Release (CE deb) sub 4096R/F273FCD8 2017-02-22 ``` 4. Use the following command to set up the **stable** repository. You always need the **stable** repository, even if you want to install builds from the **edge** or **test** repositories as well. To add the **edge** or **test** repository, add the word `edge` or `test` (or both) after the word `stable` in the commands below. > **Note**: The `lsb_release -cs` sub-command below returns the name of your > Debian distribution, such as `jessie`. To also add the **edge** repository, add `edge` after `stable` on the last line of the command.
```bash $ sudo add-apt-repository \ "deb [arch=amd64] {{ download-url-base }} \ $(lsb_release -cs) \ stable" ```
```bash $ echo "deb [arch=armhf] {{ download-url-base }} \ $(lsb_release -cs) stable" | \ sudo tee /etc/apt/sources.list.d/docker.list ```
5. **Wheezy only**: The version of `add-apt-repository` on Wheezy adds a `deb-src` repository that does not exist. You need to comment out this repository or running `apt-get update` will fail. Edit `/etc/apt/sources.list`. Find the line like the following, and comment it out or remove it: ```none deb-src [arch=amd64] https://download.docker.com/linux/debian wheezy stable ``` Save and exit the file. > **Note**: Starting with Docker 17.06, stable releases are also pushed to > the **edge** and **test** repositories. [Learn about **stable** and **edge** channels](/engine/installation/). #### Install Docker CE > **Note**: This procedure works for Debian on `x86_64` / `amd64`, Debian ARM, > or Raspbian. 1. Update the `apt` package index. ```bash $ sudo apt-get update ``` 2. Install the latest version of Docker CE, or go to the next step to install a specific version. Any existing installation of Docker is replaced. ```bash $ sudo apt-get install docker-ce ``` > Got multiple Docker repositories? > > If you have multiple Docker repositories enabled, installing > or updating without specifying a version in the `apt-get install` or > `apt-get update` command will always install the highest possible version, > which may not be appropriate for your stability needs. {:.warning} 3. On production systems, you should install a specific version of Docker CE instead of always using the latest. This output is truncated. List the available versions: ```bash $ apt-cache madison docker-ce docker-ce | {{ site.docker_ce_stable_version }}.0~ce-0~debian | https://download.docker.com/linux/debian jessie/stable amd64 Packages ``` The contents of the list depend upon which repositories are enabled. Choose a specific version to install. The second column is the version string. The third column is the repository name, which indicates which repository the package is from and by extension its stability level. To install a specific version, append the version string to the package name and separate them by an equals sign (`=`): ```bash $ sudo apt-get install docker-ce= ``` The Docker daemon starts automatically. 4. Verify that Docker CE is installed correctly by running the `hello-world` image. **x86_64**: ```bash $ sudo docker run hello-world ``` **armhf**: ```bash $ sudo docker run armhf/hello-world ``` This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits. Docker CE is installed and running. You need to use `sudo` to run Docker commands. Continue to [Linux postinstall](/engine/installation/linux/linux-postinstall.md) to allow non-privileged users to run Docker commands and for other optional configuration steps. For Raspbian, you can optionally [install Docker Compose for Raspbian](#install-docker-compose-for-raspbian). #### Upgrade Docker CE To upgrade Docker CE, first run `sudo apt-get update`, then follow the [installation instructions](#install-docker), choosing the new version you want to install. ### Install from a package If you cannot use Docker's repository to install Docker CE, you can download the `.deb` file for your release and install it manually. You will need to download a new file each time you want to upgrade Docker. 1. Go to `{{ download-url-base }}/dists/`, choose your Debian version, browse to `pool/stable/`, choose either `amd64` or `armhf`, and download the `.deb` file for the Docker CE version you want to install. > **Note**: To install an **edge** package, change the word > `stable` in the URL to `edge`. > [Learn about **stable** and **edge** channels](/engine/installation/). 2. Install Docker CE, changing the path below to the path where you downloaded the Docker package. ```bash $ sudo dpkg -i /path/to/package.deb ``` The Docker daemon starts automatically. 3. Verify that Docker CE is installed correctly by running the `hello-world` image. ```bash $ sudo docker run hello-world ``` This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits. Docker CE is installed and running. You need to use `sudo` to run Docker commands. Continue to [Post-installation steps for Linux](/engine/installation/linux/linux-postinstall.md) to allow non-privileged users to run Docker commands and for other optional configuration steps. For Raspbian, you can optionally [install Docker Compose for Raspbian](#install-docker-compose-for-raspbian). #### Upgrade Docker CE To upgrade Docker, download the newer package file and repeat the [installation procedure](#install-from-a-package), pointing to the new file. {% include install-script.md %} ## Install Docker Compose for Raspbian You can install Docker Compose using `pip`: ```bash $ sudo pip install docker-compose ``` [Hypriot](https://hypriot.com/){: target="_blank" class="_" } provides a static binary of `docker-compose` for Raspbian. It may not always be up to date, but if space is at a premium, you may find it useful. To use it, first follow Hypriot's [instructions for setting up the repository](https://blog.hypriot.com/post/your-number-one-source-for-docker-on-arm/){: target="_blank" class="_" }, then run the following command: ```bash sudo apt-get install docker-compose ``` ## Uninstall Docker CE 1. Uninstall the Docker CE package: ```bash $ sudo apt-get purge docker-ce ``` 2. Images, containers, volumes, or customized configuration files on your host are not automatically removed. To delete all images, containers, and volumes: ```bash $ sudo rm -rf /var/lib/docker ``` You must delete any edited configuration files manually. ## Next steps - Continue to [Post-installation steps for Linux](/engine/installation/linux/linux-postinstall.md) - Continue with the [User Guide](/engine/userguide/index.md).
