For a list of supported operating systems and distributions for different Docker editions, see [Docker variants](/install/index.md#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/debian' %} 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` fails. 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](/install/index.md). #### 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: ```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 always installs the highest possible version, > which may not be appropriate for your stability needs. 3. To install a _specific version_ of Docker CE, list the available versions in the repo, then select and install: a. List the versions available in your repo: ```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 ``` b. Install a specific version by its fully qualified package name, which is the package name (`docker-ce`) plus the version string (2nd column) up to the first hyphen, separated by a an equals sign (`=`), for example, `docker-ce=18.03.0.ce`. ```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. The `docker` group is created but no users are added to it. You need to use `sudo` to run Docker commands. Continue to [Linux postinstall](/install/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 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](/install/index.md). 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. The `docker` group is created but no users are added to it. You need to use `sudo` to run Docker commands. Continue to [Post-installation steps for Linux](/install/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](/install/linux/linux-postinstall.md) - Continue with the [User Guide](/engine/userguide/index.md).
