These instructions work for Docker EE for Oracle Linux and for Docker EE for Linux, which includes access to Docker EE for all Linux distributions.To get this information: - Go to [https://store.docker.com/my-content](https://store.docker.com/my-content). - Choose **Get Details** / **Setup Instructions** within the **Docker Enterprise Edition for Oracle Linux** section. - Copy the URL from the field labeled **Copy and paste this URL to download your Edition**. Use this URL when you see the placeholder text ``. To learn more about Docker EE, see [Docker Enterprise Edition](https://www.docker.com/enterprise-edition/){: target="_blank" class="_" }. ### OS requirements To install Docker EE, you need the 64-bit version of Oracle Linux 7.3 running the Red Hat Compatible kernel (RHCK) 3.10.0-514 or higher. Older versions of Oracle Linux are not supported. In addition, you must use the `devicemapper` storage driver if you use Docker EE. On production systems, you must use `direct-lvm` mode, which requires one or more dedicated block devices. Fast storage such as solid-state media (SSD) is recommended. ### Uninstall old versions Older versions of Docker were called `docker` or `docker-engine`. If these are installed, uninstall them, along with associated dependencies. ```bash $ sudo yum remove docker \ docker-engine \ docker-engine-selinux ``` It's OK if `yum` reports that none of these packages are installed. The contents of `/var/lib/docker/`, including images, containers, volumes, and networks, are preserved. The Docker EE package is now called `docker-ee`. ## Install Docker EE You can install Docker EE 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. - Some users download the RPM package and install it manually and manage upgrades completely manually. This is useful in situations such as installing Docker on air-gapped systems with no access to the internet. ### Install using the repository Before you install Docker EE for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker EE from the repository. #### Set up the repository 1. Remove any existing Docker repositories from `/etc/yum.repos.d/`. 2. Store your EE repository URL in `/etc/yum/vars/dockerurl`. Replace `` with the URL you noted down in the [prerequisites](#prerequisites). ```bash $ sudo sh -c 'echo "/oraclelinux" > /etc/yum/vars/dockerurl' ``` 3. Install required packages. `yum-utils` provides the `yum-config-manager` utility, and `device-mapper-persistent-data` and `lvm2` are required by the `devicemapper` storage driver. ```bash $ sudo yum install -y yum-utils device-mapper-persistent-data lvm2 container-selinux ``` 4. Use the following command to add the **stable** repository: ```bash $ sudo yum-config-manager \ --add-repo \ /oraclelinux/docker-ee.repo ``` #### Install Docker EE 1. Update the `yum` package index. ```bash $ sudo yum makecache fast ``` If this is the first time you have refreshed the package index since adding the Docker repositories, you will be prompted to accept the GPG key, and the key's fingerprint will be shown. Verify that the fingerprint matches `77FE DA13 1A83 1D29 A418 D3E8 99E5 FF2E 7668 2BC9` and if so, accept the key. 2. Install the latest version of Docker EE, or go to the next step to install a specific version. ```bash $ sudo yum -y install docker-ee ``` 3. On production systems, you should install a specific version of Docker instead of always using the latest. List the available versions. This example uses the `sort -r` command to sort the results by version number, highest to lowest. The output is truncated. > **Note**: This `yum list` command only shows binary packages. To show > source packages as well, omit the `.x86_64` from the package name. {% assign minor-version = "17.03" %} ```bash $ yum list docker-ee.x86_64 --showduplicates | sort -r docker-ee.x86_64 {{ minor-version }}.0.el7 docker-ee-stable ``` The contents of the list depend upon which repositories you have 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 a hyphen (`-`): ```bash $ sudo yum -y install docker-ee- ``` 4. Edit `/etc/docker/daemon.json`. If it does not yet exist, create it. Assuming that the file was empty, add the following contents. ```json { "storage-driver": "devicemapper" } ``` 5. For production systems, you must use `direct-lvm` mode, which requires you to prepare the block devices. Follow the procedure in the [devicemapper storage driver guide](/engine/userguide/storagedriver/device-mapper-driver.md#configure-direct-lvm-mode-for-production){: target="_blank" class="_" } **before starting Docker**. 6. Start the Docker daemon. ```bash $ sudo systemctl start docker ``` 7. Verify that Docker EE 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 EE is installed and running. You need to use `sudo` to run Docker commands. Continue to [Linux postinstall](linux-postinstall.md) to allow non-privileged users to run Docker commands and for other optional configuration steps. #### Upgrade Docker EE To upgrade Docker EE, first run `sudo yum makecache fast`, then follow the [installation instructions](#install-docker), choosing the new version you want to install. ### Install from a package If you cannot use the official Docker repository to install Docker EE, you can download the `.rpm` file for your release and install it manually. You will need to download a new file each time you want to upgrade Docker EE. 1. Go to the Docker EE repository URL associated with your trial or subscription in your browser. Browse to `oraclelinux/7/x86_64/stable-{{ minor-version }}/Packages` and download the `.rpm` file for the Docker version you want to install. 2. Install Docker EE, changing the path below to the path where you downloaded the Docker package. ```bash $ sudo yum install /path/to/package.rpm ``` 3. Edit `/etc/docker/daemon.json`. If it does not yet exist, create it. Assuming that the file was empty, add the following contents. ```json { "storage-driver": "devicemapper" } ``` 4. For production systems, you must use `direct-lvm` mode, which requires you to prepare the block devices. Follow the procedure in the [devicemapper storage driver guide](/engine/userguide/storagedriver/device-mapper-driver.md#configure-direct-lvm-mode-for-production){: target="_blank" class="_" } **before starting Docker**. 5. Start the Docker daemon. ```bash $ sudo systemctl start docker ``` 6. Verify that Docker EE 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 EE is installed and running. You need to use `sudo` to run Docker commands. Continue to [Post-installation steps for Linux](linux-postinstall.md) to allow non-privileged users to run Docker commands and for other optional configuration steps. #### Upgrade Docker EE To upgrade Docker EE, download the newer package file and repeat the [installation procedure](#install-from-a-package), using `yum -y upgrade` instead of `yum -y install`, and pointing to the new file. ## Uninstall Docker EE 1. Uninstall the Docker EE package: ```bash $ sudo yum remove docker-ee ``` 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 ``` 3. If desired, remove the `devicemapper` thin pool and reformat the block devices that were part of it. 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).
